Mr. Rhenium Simply traveling at a high percentage of c causes time dilatation so anything and anyone inside the ship experiences a shorter duration than those observing from the sidelines. This only becomes useful closer to c than the early designs in this video. Actually reaching or surpassing c would require finding a significant flaw in Einstein's theories of relativity, while reaching 99.9% of c only requires a lot of energy and the time to accelerate at a survivable G force.
It would be funny if, in a few years time, we spotted thousands of tiny probes shooting through the solar system at 20% the speed of light, originating from Proxima Centauri.
If it is, I would expect somewhat larger probes, or even manned "or aliened" ships, as they would be getting a *lot* of power from their star. Still, it's about 1400 light years away, so we're probably safe for a few more centuries...
That possibility has been discussed on Centauri Dreams www.centauri-dreams.com . A 1-kilogram probe moving at 0.3 c (30% of the speed of light) would, if it hit a planet, release as much energy as a 1-megaton nuclear weapon! The Starshot probes will weigh considerably less than 1 kilogram and will travel more slowly ("only" 0.2 c), but they will still pack the punch of a nuclear bomb. Stellar systems are by far mostly empty space, so the odds of a Starshot probe hitting a planet, moon, asteroid, or comet in the Alpha Centauri system (including in the very diffuse Oort comet clouds of its stars) are very tiny, but not zero...
1. At the speed of light? An entire PLANET is only a few miles thick relative to an object moving that fast, so an atmosphere is effectively non-existent. 2. Lighten up, Francis.
chocolatecrud well because of the dark ages religion brought us. Maybe we could have gone to space by the year 1500 if Catholic church wouldn't have been cutting everyone's head who thought the Earth orbited the sun, but not really since I don't think the world would have even been ready for it yet, but who knows what we could have achieved by now if the Catholic church wouldn't have been feeding bullshit to people and saying they already know everything there is to know about the world and killing everyone who disagrees. We can thank the people who stood up against the Catholic Church for getting us out of the horrible dark ages.

You will not. Even if they launch those little probes it will take 20 years for them to get there and 5 years for the signal to come back. That's all you're going to see. Maybe.
About 20 years until expected launch, another 20 years to reach their destination, plus about 4.4 years for the signal to return. About 45 years. If you are under 40 (maybe even if you are a little over 40) then you should be able to make it if you eat healthy and exercise (the average lifespan of an American male is just a little under 80 years, so if you are on the edge you may need to push a bit past the average, but average lifespans should increase a bit in that time too). I know I'm planning on sticking around for it.
Let's just hope our galaxy is closer to like star trek and not warhammer 40k. With the latter we'd be better off just minding our own business and not make ourselves visible in any way
Its so sad that most likely we wont see interstellar travel within most of our lifetimes. Im 15 and have been obsessed with space since 6 years old. Maybe i have a chance at being around to hear the news that we have reached interstellar planets and stuff.
Don't give up hope. There is a universe of fascination out there. When I was younger I felt much the same as you, being a massive Star Trek fan, I was depressed that we may never have something like warp drive. But the more science I read the more excited I got in general. Also, in a few weeks I may have my next video out about the Solar Gravitational Lens. Where by using the lensing effect of our sun, we may be able to image an exoplanet. Something that I would be very confident in seeing happen in mine and your life time.
take baby steps, first lets get to common manned interplanetary flights and colonize other planets/moons within sol before we go to hell also known as interstellar space. at that point we will have hopefully invented better technology.

"but exploration is scary and what if we find more immigrants in space? We have too few walls built on earth to be throwing money into space." -says the average person in the U.S.
Lightspeed would allow us to travel to planets in MINUTES. Just think of going to Earths moon or to Mars in a snap. 1.3 light seconds is the distance between us and the moon so it would be tricky traveling at light speed and highly dangerous, we’d probably go a bit slower but STILL, imagine being on Earth one minute, then landing on the moon the next. Mars is 3 light minutes from us!
@@Pr0fane26 Subluminal speeds are still pretty fast though. Using Orion drives or fusion drives we could reach between 1-10% lightspeed which means you can go anywhere in the Solar System in just weeks.
Don’t be too proud of this technological terror you’ve constructed. The ability to travel at light speed is insignificant next to the power of the Force.
10 billion is half NASAs budget. That's 50%. 10 billion is 1.6% of the military budget. Imagine if NASA took half of the military budget, or even a quarter.... The progress we've made in 30 years could have been done in 3.
Josh Latham trust that nasa really has as much money as they need u people sound dumb when u consider what a military needs compared to what a space program needs. Anything nasa wants to build they can anything they need done they get done. Even with 600 billion our military always needs so much done and added to it.
Two things to keep in mind with interstellar space travel. First, no matter how fast you go, you also have to slow down once you arrive at your destination. Second, at very high speeds you run the risk of even small particles of dust destroying your spacecraft. So some sorta magnetic shield would have to be developed to deflect anything solid in the path of your spaceship.
Halfway there, you have to turn around and begin slowing down. Also, as you approach those speeds, doppler effect changes the colors of visible light and wavelengths of radio frequencies (yes, technically the same thing). You'll have more purples and higher freqency radio in front, and shifting to infra-red and lower frequency radio in the rear. Approaching the edge of light speed, you'd get a blackout in the rear.
Magnetic field technology is the key to going lightspeed once you get into space two frozen magnets on a track and one in the middle cock it back with a spring like a gun
@@inventorstar5816 I agree with the magnetic field idea. Somehow they will have to generate a magnetic field around their spacecraft that is strong enough to deflect small rocks and even various types of radiation. Seems like a better option than heavy armored spacecraft walls.
@@Saugaverse that won't work if the spacecraft reach near speed of light since magnetic force acted on speed equals to speed of light..Before detection the obstacles the spacecraft will collide with them.
@@shamsalveera yes plus this magnetic field or armor around the spacecraft would have to be capable of withstanding enormous forces since if it hits even a small rock that almost looks like dust weighting 0.001 kg the energy generated by the impact would be equal to a nuclear explosion

People tend to think that relativity is a hindrance to exploring the galaxy because of c speed limit, not realizing that there is no limitation on how quickly a traveler can get to any particular destination in their own accelerating frame of reference, and in fact length contraction makes travel easier at relativistic speeds compared to how it would be in a cartesian universe. As you accelerate once you're at relativistic speeds length contraction increasingly decreases the distance you need to travel. 20% of c is already starting to show the effect. Just using the lorentz time dilation transformation on the example given of traveling at 20% c to Proxima C, 4 light years away, shows that while from earth it looks like it took you 20 years to get there, it really took you 18.8 years to get there. As you start edging beyond 20% c, that difference can become much bigger. If you were going 50% c, earth would see you get there in 10 years, but you'd really get there in 6.9 years.
Dude why the hell would you stop making videos?!!! I mean you made such amazing animation in each of your videos and many of them if not all were hits.
*To give many of you an idea how fast light moves, it could orbit the Earth 7.5 times in ONE second. Getting a satellite to move 1/5th of that is insanely fast.*
Jarvis Wilson-short there are a few problems with that claim. The most substantial being it doesn't make sense. The terms used to describe its operational capacity are incongruent. Saying that something can prepulse (maybe that was a typo) at X times the speed of light, is like saying that you can jump rope 24 times at 60mph. It doesn't say anything about velocity. Secondly, is the unlikelihood of a conspiracy to hide a miraculous technology from the world, especially coming out of China considering how globally competitive they are. Third is the this competitive nature that China has to be the first or the best at something, which has lead to numerous unverifiable scientific discoveries. Granted I'm only going off of what you said, and that I haven't seen the video you mentioned. But it sounds like there is already too much wrong with the claim to grant any reasonable credibility toward.
paki ... from your comment, you might be interested in my responses to some other related comments: Marlo Mamocod :) It would require infinite energy for a massive object or ship to reach the speed of light. However, a significant fraction of light speed 5 percent or 10 percent or even 15 to 20 percent is currently possible using lasers against a sail, or solar sails, or plasma (ion) drive engines of a craft. Warp drive engines are theoretical and promise much faster than light speed in the hopeful future and without the effects of Einstein's time-dilation as per his General Relativity Theory where time slows down proportionately to accelerating toward light speed. For each hour of the astronaut's time more time goes by for those left behind on earth. The astronaut could return in a year or two of his time experience and find his friends much older or dead of old age. Time-dilation would not apply traveling to other star systems using warp-drive technology in the hopeful future. Using warp drive means using a ring or torus to compress space in the direction of "travel" and expanding space in the opposite direction. The resulting effect is that the so called warp bubble alternately compresses and expands space to impart a forward traveling potentially faster that light travels in normal space-time (space + time). It can be very roughly compared to surfing a giant wave (instead of traveling in the water like a boat) toward the sandy beach full of pretty ladies in bikinis. So, within the warp field bubble, there is no speed relative to normal space-time outside the warp field bubble meaning Einstein's time-dilation would not apply. ============================================================ Farmer Bold Patrick Desch, You are close, sir. But Dark Matter represents the majority of mass in the universe ... "dark" because scientists do not know what it is even though it bends light through space-time as in the gravity-lens effect. Dark Matter accounts for about 25 percent of matter-energy, normal matter-energy accounts for almost 5 percent, and Dark Energy is about 70 percent of energy "dark" because scientist do not know what it is but it is causing the visible universe to expand increasingly fast rather than to slow down due to gravity in the universe of all stars, black holes, planets and moons etc. "Normal matter" has mass due to their protons and neutrons inside the nucleus of atoms with hydrogen atoms having only a proton (deuterium is hydrogen or a hydrogen isotope with one proton and a neutron in the nucleus orbited by a single electron. Deuterium is stable meaning not radioactive. And tritium is a hydrogen isotope with one proton and two neutrons and is not stable as it is radioactive. Any element like hydrogen or oxygen or iron or lead are defined by the number of protons that is the atomic number of the element or atom.). Recently, it was discovered that the "god particle" provided a Higgs-Boson (after the name's of two scientists) field that imparts mass (weight in the presence of gravity) to matter excluding photons or particles of light that is part of the electromagnetic spectrum (including radio waves, radar waves, infra-red or heat waves, visible light waves, ultraviolet waves that darken human skin, x-ray waves, gamma radiation waves, and cosmic radiation waves of infinitely increasing frequencies. As you correctly pointed out, photons have no mass and that is why photons are normally always moving in space-time (space + time) at almost 300,000 kilometers per second or 286,282.4 (?) miles per second relative to massive objects including people. ==================================================== ben l 9 months ago but could we send photos back from another star? ----- Farmer Bold Yes, photos and other data from other stars within a couple of decades or so. We will send a cluster of very small crafts using a number of lasers on earth to propel small sails for each craft for just a few minutes. Each sail with tiny craft would accelerate to around 20 (to 30???) percent light speed during a period of several minutes. They would not have to slow down or decelerate when approaching and passing the nearest binary star system that is 4.3 light years from earth. Photos and other data would be sent back to earth at about the speed of light of planets and moons of that distant star system. The cluster of many craft would insure more exposure and greater success and cover more objects in the other star system or systems. The craft will just continue traveling into deep interstellar space after the mission of sending photos and other data back to earth. ====================================================== Farmer Bold Jimiticus ... Wow! I use to wonder if such tech is possible. And if the sun then Dark Matter's gravity lens effect can be used for even better resolution of stars and exoplanets etc at much greater distances from earth. :)
A LITTLE SCIENCE LESSON since I majored in science: "PLASMA" is the fourth (4th) state of matter ... 1. solid, 2. liquid, 3. gas, and 4. plasma. Plasma is extremely hot so as to ionize ATOMS into their negative and positive parts (electrons are negatively charged and protons are positively charged). An ATOM is the smallest part of any element of matter (stuff). Elements include hydrogen, helium, carbon, oxygen, iron, sulfur, sodium, chlorine, and uranium etc. But elements can combine or come together in a chemical reaction such as when oxygen and hydrogen combine to make water (H2O or H . O where . is the number 2) that is two hydrogen atoms and one oxygen atom making water). Sodium and chlorine chemically combine to make table salt (table salt is sodium chloride). ATOMS are neutral or without a charge or electric charge simply because atoms have the same number of neg. electrons orbiting the center or nucleus of an atom as the atom has positively charged protons located inside the nucleus or center of the atom. Note that a hydrogen atom has only one proton and only one electron ... but all other atoms have more protons and more electrons along with one or more NEUTRONS. Neutrons in the center of atoms have no charge and are therefore neutral in charge. But neutrons add to how heavy the atom is or add to the weight or atomic-weight of atoms. So, the simplest atom is the HYDROGEN ATOM with one proton in the middle and one electron going around or orbiting that proton. And a helium atom has two protons and two neutrons being orbited by two electrons. The atomic number of helium is two (because of two protons). And the atomic weight of helium is four (4) because of the two protons and two neutrons that weight almost the same (protons and neutrons). Electrons have a negligible or very light weight so typically don't need to be counted as adding to the weight of an atom. Now, when there is a TRANSFER of one or more neg. electrons then the atom that loses the electron(s) has more positively charged protons in the center or nucleus ... and the atom that receives one or more neg. electrons then has a neg. charge making the atoms now IONS. Ions are just atoms with a charge either positive or negative charge. An IONIC chemical reaction is the combination of OPPOSITELY CHARGED ions (that were atoms) and refers to the TRANSFER of neg. electrons from one atom to the other making them IONS with opposite charges that attract each other to make A COMPOUND such as table salt and water etc. In a PLASMA ROCKET, a hydrogen atom is ionized by heating it into plasma using microwaves (like in a microwave oven for food). The plasma is the hydrogen ion that is just a single proton. And the neg. electron is the other ion or charged particle. These ions come back together after the exhaust of the plasma rocket to form back into hydrogen with a neutral charge or no charge. The high speed of the exhaust of the rocket is very high in the energy of motion causing a reaction to push the rocket in the opposite direction or forward (as further into space). Plasma rockets that are actually ION ROCKETS, is an attractive method for drones or even people to travel to the stars such as to the nearest ones starting about 4.4 light years away. A light year is the distance light travels in a year that is about seven (7) times around the earth in a second. So, it would take about 46 years or more gradually speeding up to about 10 percent or a little faster the speed of light using ion drive engines or plasma rockets to get to the nearest star system. But about 96 years if people want to start slowing down half way there so as to maybe land on one one of the orbiting planets there. The earth people could complete the construction of a gigantic star ship (using small fusion bombs that are small nuclear bombs to power large ships with large amounts of materials into earth orbit. These materials would then be used in orbit to construct great star ships. This construction, if the world cooperates, might be done or completed over a period of maybe several decades (depending on how much billionaires are taxed etc.) like a Noah's arch star ship or several of them all in order to save humanity (several hundred people and plant/animal genetic material or embryos for each star ship) maybe from earth's collision with a giant asteroid so that people can be re-seeded to survive on a distant habitable planet. Several star ships are better than a single ship as per the saying "Don't put all your eggs into one basket." I'm too old to go, but I do not mind happily staying behind with billions of other people all in order to save enough of humanity or several thousand people including samples of all races and not just one or two dominant races of people ... you know what I mean.
When atoms are propelled to high speeds (1/2 the speed of light) the electrons of an atom go into a higher orbit changing the structure of the atom. This in turn changes the structure of the material the atoms make up. At high speeds, steel could have the strength and texture of Jello.

The worst thing about faster than light travel is, if you're going faster than light then you are literally time travelling.

Henry Jiang 10 billion divided by 17 trillion is way less than 7%. Less than .1%, but more importantly those lasers will continue to be useful long after this mission. It has been suggested that we should shoot lasers right below spacecraft simulating combustion by heating up the air with the lasers. If we dont have to carry the fuel we can reduce the weight of spacecraft and carry a lot more cargo for the same cost. If we do become an interplanetary species or even if we just need to reduce the cost of satelites or asteroid mining those lasers will eventually pay for themselves.
gcross82 prolly wont build new power plants just a capacitor bay that will charge for a week durring non peak power ussage. Then use that to help keep that power plant from needing to worry about peak power ussage and run it at its most efficient fuel consumption rate.
All I want before I die is for us to find another planet similar to earth with life on it or for aliens to make contact and give us the technology to travel through space.

Don’t forget all of the molecular debris not to mention micrometeorites and hard rocks in the way. A functional force field is needed in order to travel that fast first.
Space and distance between things are so big, that when our galaxy collides with Andromeda, NO planets, stars etc. will hit eachother. That's how big we are talking.
We need a spacecraft designed to detect these things. Send several detectors outward toward Rigel or Centari system that measure particles including radiation. They could serve as long range sensors for future missions to these systems and might even be able to shed some light on Dark matter.
some thousand years ago, the handheld device you are using to watch this video would have been claimed practically and theoretically impossible. you claim depends upon the knowledge you currently have. in the age of 1500s, the gunpowder was a new thing, but if I had told you a about a 100MT Tsar Bomba (the original idea that dropped fearing uncalculated consequences) the idea would have been a joke. never stop progressing, the universe is a matrix and everything can happen.
But to send everything there.. why not send it to space direct... Only if the moon had all resources and you colonised it, and it ran like a real country with mining and manufacturing etc. etc. Light weight propulsion like proposed at the end is way easier and more realistic than spending trillions colonising the moon, however fun that sounds (which does sound like fun)
The moon isn't very far in terms of distance. It wouldn't really give much of an advantage other than less fuel spent exiting its gravitational pull vs. exiting Earth's.

If we can figure out autonomous automation, space mining, and how to process & refine & manufacture in space. We could send an autonomous expedition to the Centauri system. From there we could send back data about the system, and figure out if it’s worth sending people. If not, we just repeat that with other systems until we have a system worth sending people to.

Don't forget even if these huge speeds are attainable, you still have to have enough energy left to stop the thing when it gets to see where it's going, it's not just about acceleration, you have to be able to stop it.
Also protection. A shield of some kind would be needed. One grain of sand that hits an object at those speeds would be like an nuclear bomb going off thus destroying the spacecraft.
In Star Trek, "warp speed" was an inaccurate phrase. "Warp" was accurate, but "speed" was relative; "factor" is more correct. Technically, space was "warped" or bent in order to shorten the distance and, thus, allow ships to traverse longer distances in a shorter and shorter amount of time. The "warp factor" was about how much bend, not velocity (aka, speed). We tend to view the time it takes to move from one location to another location in measurements of velocity, hence the colloquial (and inaccurate) "warp speed." Thus, while warp speed may be impossible, warp factors may not be.
That's right - so even if you could get a ship up to light speed, it still takes much longer than light photons to get anywhere with the time of acceleration and deceleration.
@@BjarkeTaunajik Still can't do too much because it requires NEW technology not extreme efforts on existing technology. THat's why particle physicists are not building 100TeV colliders.
@@BjarkeTaunajik Not exactly. You MAY speed up the process - but once you hit fundamental limits it will only be refinements until you have breakthroughs in theoretical work. Look at the state of theoretical physics right now....getting so esoteric so that predictions made by a theorist are verified or refuted 100 years later. I'm not saying pouring 1000X more money into the effort won't help significantly, of course it will - but not like you think. That the hurdles are not funding, it's transitioning to new paradigms in scientific understanding and technology and if it doesn't develop independently from OTHER markets then the amount of effort is exponentially increased. Cumulatively worldwide, the commercial tech sector (for relevant things like like microprocessor development, AI, etc) likely exceeds the numbers you have listed. These developments are directly contributive to any space program and to humanity in general, but would never factor into a NASA budget because they don't reinvent the wheel when installing computing devices in their spacecraft. The better those beccome the better everything else becomes Another example: they discussed inertial confinement fusion here, which is outside of space program and related to commercial interests in nuclear fusion. Same idea. In many cases the technology developed for basic research (e.g. nuclear and particle physics in the 1920's) found its way into the consumer market later, but now it is the other way around. Also regarding military spending - that technology developed for warfare contributes as well. Obviously if we stopped all military spending and had societies that made this unnecessary, and then gave everything to space explorations and related fields it would improve progress noticeably, but it's not a simple 1:1 correspondence and it may not be AS good a reallocation of funds as you think.

@@dailydoseoftiktok1368 But that is like saying what if you get something colder than 0 Kelvin. You could however ask, what happens if we get to 99.9% of the speed of light. Then we can estimate what would happen. In that case, light would still move away from you and toward you at the speed of light. Light speed is always relative to your frame of reference. So, you can never catch up to light and have it stopped next to you.

@@allistairneil8968 this confused me, too. He's saying a solar sail 1 km by 1 km (which he wrongly shows as the same length as the Ghost spacecraft that he previously said was 1.2 km long) only weighs a kilogram -- about the weight of a kitten (at 7-12 weeks old). Earlier, he also wrongly portrayed the IKAROS spacecraft as being 14x14 millimeters (it's actually 14x14 meters!) and weighing 310 kg (that's a lot of kittens!). In fact, the IKAROS sail with support structure only weighs around 2.5 kg. The launch mass (which I take to mean the entire rocket used to launch and deploy the sail) is 315 kg. As with the kitten, the nickel shown next to the 4 m x 4 m Project Breakthrough Starshot nanocraft is meant as compare weight, not size. (US nickels weigh 5 grams and Canadian nickels, 3.95 grams.)

According to our current level of technology it is impossible. That does not mean it cannot be done. Look at how many things were impossible 200 years ago, 50 years ago.
If we are using sails like in the video we could use proxima Centaris light to gradually slow us down when we get within a decent distance from it so it could take an extra 2 years or so to slow down at a safe rate but it could take longer or shorter depending on how calculated the time of the slowing process begins but since it's such a small object I don't see it taking too much time to slow down due to the solar energy of the star or stars in the proxima system
That is really the fundamental problem with deep space travel. The speed of light is chump change if you want to visit anything beyond neighboring star systems and definitely intergalactic travel. You need MILLIONS of times the speed of light. And here we are, being total scrubs trying to figure out how to get things up to 2 or 3% the speed of light.
@@ninjaman1714 Lol, just think about it: How large is our galaxy? How large is the universe? Any idea what that means? That means also rthat light is quite slow in contrast to the huge space. Even to our nearest star-system light need several years.
One other catch is as you at relativistic speeds even the extremely thin interstellar medium starts to look like a you are traveling towards a particle accelerator. The intensity of radiation and erosion of the craft becomes an issue.
Also, i know that BFR and Falcon Heavy are 2 different things (but isn't it cool that the test payload will be a Tesla Roadster heading for a billion year elliptical Mars orbit? :D)

The speed of light is in fact the maximum speed that any kind of signal or information can ripple through the spacetime fabric we all live in - it is the speed of reality - or causality. Lights travels unhindered at the maximum speed as it has no mass so that we we call it the same. It would be better to call it the speed of spacetime or speed of reality. If you go faster than the spacetime limit you end up time travelling with a whole lot of paradox questions to face - not just a big energy bill.
@@Thesamurai1999 It's not that only massive things are affected by gravity. That's the old, pre-Einsteinian view. Einstein said that what was actually happening was that objects with mass cause spacetime to curve. Light travels in a straight line through spacetime, but if the spacetime is curved, the "straight line" (from the photon's point of view") curves along with it.
Two of the most realistic interstellar space vessels Hollywood has made so far are the Venture Star (Avatar, 2009) and the Avalon (Passengers, 2016). The Venture Star is powered by anti-mater + nuclear fusion; while the Avalon is powered only by nuclear fusion. The Venture Star can travel at 130,000 mi/sec (209,537 km/sec); while the Avalon can travel at 93,000 mi/sec (150,000 km/sec). Both ships have living areas which generate gravity via centrifugal force, and both ships use frontal shields to protect from incoming debris.
Two questions: 1) how will they slow down when reaching the destinations? 2) how will they protect themselves from impact with micrometeorites and dust particles?
Yeah. That's kinda a problem. Another problem is: If something hit some alien at 20% of light-speed they'd think, "Holy shit! Earth is shooting at us! Let's go wipe them out!!"
@@ThatBoomerDude56 Well, is it? (Pertaining to images) Data is data, you would need a big dish for the bandwith, but, you would still recive the same images, it would just take 4 years to ge them back. If only we had some form of....... an ansible.
@@gavares3 The problem is: With a camera and transmitter the size of a nickle, at 4 light years away, would you need a receiver the size of the whole solar system?
@@ThatBoomerDude56 ya, you are right. you need a big dish. as far as transmitter is concerned, i have this super mag drive that can propel me at light speed or close to it. i can draw power from that, lots of it. for a dish, you "could" in theory use the moon, or, you could set up a few comms birds with large dishes and formation fly them. comm threads.
even bigger problem is how to properly plot course of such "craft" accounting for all wild stuff that happen andcan change crafts path or destroy it outright....
How do you propose getting that much material to the moon? The project doesn't have infinite money, so they have to only think of solutions that are cost effective.
A basic radio transmission will work just fine. It will take 4+ years for us to get the message, but communication back to Earth is the easiest part of the problem.
Learning to travel through space fast is great, but it shouldn't be just about how fast you can travel, it should also be about how short you can make the distance from where you are to where you want to go.
Kinetic energy increases to the square of a velocity increase. Impact with even a grain of sand traveling at even 1/10 the speed of light would cause total disintegration of a spacecraft.
Terry Cooper Agreed. This is the complication everyone seems to miss. Even a ‘deflector’ dish, as envisioned in Star Trek, would need to project massive amounts of energy huge distances ahead through some even more esoteric method than a light speed drive.
Wow, excellent point, not 100% accurate, but a valid and real comment about space travel. Something as small as a grain of sand, traveling at those speeds, would pass right thru a spacecraft. However, the tiny hole it left would still cause a major problem, instant decompression. And if it passed thru one of the crew ............
@@Saugaverse I actually tried to do an approximate calculation. Interstellar space is pretty empty. There are no pebbles there, only microscopic dust grains, at most 500 nm in size. At relativistic velocities these do pack a macroscopic punch - basically, the energy of a bullet, if I'm not mistaken - but in order to transfer this energy this "bullet" has to be slowed down by the spacecraft. It probably won't be - it'll shoot straight through, leaving nothing but a microscopic hole. At the end of its journey this solar sail is going to look like a sieve with billions of micrometer-sized holes per square meter - which does seem like a considerable amount of damage, tbh, but on the brink of survivability. A couple of orders of magnitude less, and it'll be fine, a couple more, and it won't make it.
@@SouperAsH that's not the point... At 20% speed of light they are planning to send several "drones" in case of "failure". So there is a chance to crush, that's why they use redundancy. Obviously in case you want to be a passenger in the future... good luck. @7:20

that when warp travel comes into play.
The only way to travel space in human time is to bend time itself
Mr. Rhenium Simply traveling at a high percentage of c causes time dilatation so anything and anyone inside the ship experiences a shorter duration than those observing from the sidelines. This only becomes useful closer to c than the early designs in this video. Actually reaching or surpassing c would require finding a significant flaw in Einstein's theories of relativity, while reaching 99.9% of c only requires a lot of energy and the time to accelerate at a survivable G force.
We're going to... *LUDICROUS SPEED!*
@dmerritt4ever
Not true because of the traveller's time dilation.
It would be funny if, in a few years time, we spotted thousands of tiny probes shooting through the solar system at 20% the speed of light, originating from Proxima Centauri.
That's halarious! Maybe that's what's going on with Taby's star!
If it is, I would expect somewhat larger probes, or even manned "or aliened" ships, as they would be getting a *lot* of power from their star.
Still, it's about 1400 light years away, so we're probably safe for a few more centuries...
Yeah I think we'll be okay. Still got my fingers crossed that it's aliens...but it's never aliens :)

Proxima Centaurians: "Where the shit are all these tin foil squares COMING from???"
That possibility has been discussed on Centauri Dreams www.centauri-dreams.com . A 1-kilogram probe moving at 0.3 c (30% of the speed of light) would, if it hit a planet, release as much energy as a 1-megaton nuclear weapon! The Starshot probes will weigh considerably less than 1 kilogram and will travel more slowly ("only" 0.2 c), but they will still pack the punch of a nuclear bomb. Stellar systems are by far mostly empty space, so the odds of a Starshot probe hitting a planet, moon, asteroid, or comet in the Alpha Centauri system (including in the very diffuse Oort comet clouds of its stars) are very tiny, but not zero...
Oops! I botched Centauri Dreams' URL--it's www.centauri-dreams.org .

You will not. Even if they launch those little probes it will take 20 years for them to get there and 5 years for the signal to come back. That's all you're going to see. Maybe.
About 20 years until expected launch, another 20 years to reach their destination, plus about 4.4 years for the signal to return. About 45 years. If you are under 40 (maybe even if you are a little over 40) then you should be able to make it if you eat healthy and exercise (the average lifespan of an American male is just a little under 80 years, so if you are on the edge you may need to push a bit past the average, but average lifespans should increase a bit in that time too).

Don't give up hope. There is a universe of fascination out there. When I was younger I felt much the same as you, being a massive Star Trek fan, I was depressed that we may never have something like warp drive. But the more science I read the more excited I got in general.

Lightspeed would allow us to travel to planets in MINUTES. Just think of going to Earths moon or to Mars in a snap. 1.3 light seconds is the distance between us and the moon so it would be tricky traveling at light speed and highly dangerous, we’d probably go a bit slower but STILL, imagine being on Earth one minute, then landing on the moon the next. Mars is 3 light minutes from us!

Mars is 20 light minutes away.
Nothing with a mass can travel near or at the speed of light. Hypersonic, yes. A quarter near light speed, not yet.
@@Pr0fane26 Subluminal speeds are still pretty fast though. Using Orion drives or fusion drives we could reach between 1-10% lightspeed which means you can go anywhere in the Solar System in just weeks.

Two things to keep in mind with interstellar space travel.
First, no matter how fast you go, you also have to slow down once you arrive at your destination.
Second, at very high speeds you run the risk of even small particles of dust destroying your spacecraft. So some sorta magnetic shield would have to be developed to deflect anything solid in the path of your spaceship.
Halfway there, you have to turn around and begin slowing down. Also, as you approach those speeds, doppler effect changes the colors of visible light and wavelengths of radio frequencies (yes, technically the same thing). You'll have more purples and higher freqency radio in front, and shifting to infra-red and lower frequency radio in the rear. Approaching the edge of light speed, you'd get a blackout in the rear.
Magnetic field technology is the key to going lightspeed once you get into space two frozen magnets on a track and one in the middle cock it back with a spring like a gun
@@inventorstar5816 I agree with the magnetic field idea.
Somehow they will have to generate a magnetic field around their spacecraft that is strong enough to deflect small rocks and even various types of radiation.
Seems like a better option than heavy armored spacecraft walls.
@@Saugaverse that won't work if the spacecraft reach near speed of light since magnetic force acted on speed equals to speed of light..Before detection the obstacles the spacecraft will collide with them.
@@shamsalveera yes plus this magnetic field or armor around the spacecraft would have to be capable of withstanding enormous forces since if it hits even a small rock that almost looks like dust weighting 0.001 kg the energy generated by the impact would be equal to a nuclear explosion

People tend to think that relativity is a hindrance to exploring the galaxy because of c speed limit, not realizing that there is no limitation on how quickly a traveler can get to any particular destination in their own accelerating frame of reference, and in fact length contraction makes travel easier at relativistic speeds compared to how it would be in a cartesian universe. As you accelerate once you're at relativistic speeds length contraction increasingly decreases the distance you need to travel. 20% of c is already starting to show the effect. Just using the lorentz time dilation transformation on the example given of traveling at 20% c to Proxima C, 4 light years away, shows that while from earth it looks like it took you 20 years to get there, it really took you 18.8 years to get there. As you start edging beyond 20% c, that difference can become much bigger. If you were going 50% c, earth would see you get there in 10 years, but you'd really get there in 6.9 years.
Dude why the hell would you stop making videos?!!! I mean you made such amazing animation in each of your videos and many of them if not all were hits.

Yup, politics are the problem... as always... and money... Man I hate humans most of the time
Jarvis Wilson-short there are a few problems with that claim. The most substantial being it doesn't make sense. The terms used to describe its operational capacity are incongruent. Saying that something can prepulse (maybe that was a typo) at X times the speed of light, is like saying that you can jump rope 24 times at 60mph. It doesn't say anything about velocity.
Secondly, is the unlikelihood of a conspiracy to hide a miraculous technology from the world, especially coming out of China considering how globally competitive they are.
Third is the this competitive nature that China has to be the first or the best at something, which has lead to numerous unverifiable scientific discoveries.
Granted I'm only going off of what you said, and that I haven't seen the video you mentioned. But it sounds like there is already too much wrong with the claim to grant any reasonable credibility toward.
That light breakthrough sounds amazing! Imagine the first exoplanet pictures only 20-30 years away from us! Wow
paki ... from your comment, you might be interested in my responses to some other related comments:
Marlo Mamocod :) It would require infinite energy for a massive object or ship to reach the speed of light. However, a significant fraction of light speed 5 percent or 10 percent or even 15 to 20 percent is currently possible using lasers against a sail, or solar sails, or plasma (ion) drive engines of a craft. Warp drive engines are theoretical and promise much faster than light speed in the hopeful future and without the effects of Einstein's time-dilation as per his General Relativity Theory where time slows down proportionately to accelerating toward light speed. For each hour of the astronaut's time more time goes by for those left behind on earth. The astronaut could return in a year or two of his time experience and find his friends much older or dead of old age.
Time-dilation would not apply traveling to other star systems using warp-drive technology in the hopeful future. Using warp drive means using a ring or torus to compress space in the direction of "travel" and expanding space in the opposite direction. The resulting effect is that the so called warp bubble alternately compresses and expands space to impart a forward traveling potentially faster that light travels in normal space-time (space + time). It can be very roughly compared to surfing a giant wave (instead of traveling in the water like a boat) toward the sandy beach full of pretty ladies in bikinis. So, within the warp field bubble, there is no speed relative to normal space-time outside the warp field bubble meaning Einstein's time-dilation would not apply.

Patrick Desch, You are close, sir. But Dark Matter represents the majority of mass in the universe ... "dark" because scientists do not know what it is even though it bends light through space-time as in the gravity-lens effect. Dark Matter accounts for about 25 percent of matter-energy, normal matter-energy accounts for almost 5 percent, and Dark Energy is about 70 percent of energy "dark" because scientist do not know what it is but it is causing the visible universe to expand increasingly fast rather than to slow down due to gravity in the universe of all stars, black holes, planets and moons etc. "Normal matter" has mass due to their protons and neutrons inside the nucleus of atoms with hydrogen atoms having only a proton (deuterium is hydrogen or a hydrogen isotope with one proton and a neutron in the nucleus orbited by a single electron. Deuterium is stable meaning not radioactive. And tritium is a hydrogen isotope with one proton and two neutrons and is not stable as it is radioactive. Any element like hydrogen or oxygen or iron or lead are defined by the number of protons that is the atomic number of the element or atom.). Recently, it was discovered that the "god particle" provided a Higgs-Boson (after the name's of two scientists) field that imparts mass (weight in the presence of gravity) to matter excluding photons or particles of light that is part of the electromagnetic spectrum (including radio waves, radar waves, infra-red or heat waves, visible light waves, ultraviolet waves that darken human skin, x-ray waves, gamma radiation waves, and cosmic radiation waves of infinitely increasing frequencies. As you correctly pointed out, photons have no mass and that is why photons are normally always moving in space-time (space + time) at almost 300,000 kilometers per second or 286,282.4 (?) miles per second relative to massive objects including people.

but could we send photos back from another star?
-----
Farmer Bold
Yes, photos and other data from other stars within a couple of decades or so. We will send a cluster of very small crafts using a number of lasers on earth to propel small sails for each craft for just a few minutes. Each sail with tiny craft would accelerate to around 20 (to 30???) percent light speed during a period of several minutes. They would not have to slow down or decelerate when approaching and passing the nearest binary star system that is 4.3 light years from earth. Photos and other data would be sent back to earth at about the speed of light of planets and moons of that distant star system. The cluster of many craft would insure more exposure and greater success and cover more objects in the other star system or systems. The craft will just continue traveling into deep interstellar space after the mission of sending photos and other data back to earth.

Jimiticus ... Wow! I use to wonder if such tech is possible. And if the sun then Dark Matter's gravity lens effect can be used for even better resolution of stars and exoplanets etc at much greater distances from earth. :)
A LITTLE SCIENCE LESSON since I majored in science:
"PLASMA" is the fourth (4th) state of matter ... 1. solid, 2. liquid, 3. gas, and 4. plasma. Plasma is extremely hot so as to ionize ATOMS into their negative and positive parts (electrons are negatively charged and protons are positively charged). An ATOM is the smallest part of any element of matter (stuff). Elements include hydrogen, helium, carbon, oxygen, iron, sulfur, sodium, chlorine, and uranium etc. But elements can combine or come together in a chemical reaction such as when oxygen and hydrogen combine to make water (H2O or H . O where . is the number 2) that is two hydrogen atoms and one oxygen atom making water). Sodium and chlorine chemically combine to make table salt (table salt is sodium chloride). ATOMS are neutral or without a charge or electric charge simply because atoms have the same number of neg. electrons orbiting the center or nucleus of an atom as the atom has positively charged protons located inside the nucleus or center of the atom. Note that a hydrogen atom has only one proton and only one electron ... but all other atoms have more protons and more electrons along with one or more NEUTRONS. Neutrons in the center of atoms have no charge and are therefore neutral in charge. But neutrons add to how heavy the atom is or add to the weight or atomic-weight of atoms. So, the simplest atom is the HYDROGEN ATOM with one proton in the middle and one electron going around or orbiting that proton. And a helium atom has two protons and two neutrons being orbited by two electrons. The atomic number of helium is two (because of two protons). And the atomic weight of helium is four (4) because of the two protons and two neutrons that weight almost the same (protons and neutrons). Electrons have a negligible or very light weight so typically don't need to be counted as adding to the weight of an atom.
Now, when there is a TRANSFER of one or more neg. electrons then the atom that loses the electron(s) has more positively charged protons in the center or nucleus ... and the atom that receives one or more neg. electrons then has a neg. charge making the atoms now IONS. Ions are just atoms with a charge either positive or negative charge. An IONIC chemical reaction is the combination of OPPOSITELY CHARGED ions (that were atoms) and refers to the TRANSFER of neg. electrons from one atom to the other making them IONS with opposite charges that attract each other to make A COMPOUND such as table salt and water etc.
In a PLASMA ROCKET, a hydrogen atom is ionized by heating it into plasma using microwaves (like in a microwave oven for food). The plasma is the hydrogen ion that is just a single proton. And the neg. electron is the other ion or charged particle. These ions come back together after the exhaust of the plasma rocket to form back into hydrogen with a neutral charge or no charge. The high speed of the exhaust of the rocket is very high in the energy of motion causing a reaction to push the rocket in the opposite direction or forward (as further into space).
Plasma rockets that are actually ION ROCKETS, is an attractive method for drones or even people to travel to the stars such as to the nearest ones starting about 4.4 light years away. A light year is the distance light travels in a year that is about seven (7) times around the earth in a second. So, it would take about 46 years or more gradually speeding up to about 10 percent or a little faster the speed of light using ion drive engines or plasma rockets to get to the nearest star system. But about 96 years if people want to start slowing down half way there so as to maybe land on one one of the orbiting planets there. The earth people could complete the construction of a gigantic star ship (using small fusion bombs that are small nuclear bombs to power large ships with large amounts of materials into earth orbit. These materials would then be used in orbit to construct great star ships. This construction, if the world cooperates, might be done or completed over a period of maybe several decades (depending on how much billionaires are taxed etc.) like a Noah's arch star ship or several of them all in order to save humanity (several hundred people and plant/animal genetic material or embryos for each star ship) maybe from earth's collision with a giant asteroid so that people can be re-seeded to survive on a distant habitable planet. Several star ships are better than a single ship as per the saying "Don't put all your eggs into one basket." I'm too old to go, but I do not mind happily staying behind with billions of other people all in order to save enough of humanity or several thousand people including samples of all races and not just one or two dominant races of people ... you know what I mean.

Violent2aShadow how much does it cost to build 100 power plants to power the lasers...
Henry Jiang 10 billion divided by 17 trillion is way less than 7%. Less than .1%, but more importantly those lasers will continue to be useful long after this mission. It has been suggested that we should shoot lasers right below spacecraft simulating combustion by heating up the air with the lasers. If we dont have to carry the fuel we can reduce the weight of spacecraft and carry a lot more cargo for the same cost. If we do become an interplanetary species or even if we just need to reduce the cost of satelites or asteroid mining those lasers will eventually pay for themselves.
gcross82 prolly wont build new power plants just a capacitor bay that will charge for a week durring non peak power ussage. Then use that to help keep that power plant from needing to worry about peak power ussage and run it at its most efficient fuel consumption rate.

I think humanity will eventually need to build a base on the moon to assemble large spaceships over there
But to send everything there.. why not send it to space direct... Only if the moon had all resources and you colonised it, and it ran like a real country with mining and manufacturing etc. etc. Light weight propulsion like proposed at the end is way easier and more realistic than spending trillions colonising the moon, however fun that sounds (which does sound like fun)
The moon isn't very far in terms of distance. It wouldn't really give much of an advantage other than less fuel spent exiting its gravitational pull vs. exiting Earth's.

Don't forget even if these huge speeds are attainable, you still have to have enough energy left to stop the thing when it gets to see where it's going, it's not just about acceleration, you have to be able to stop it.
Also protection. A shield of some kind would be needed. One grain of sand that hits an object at those speeds would be like an nuclear bomb going off thus destroying the spacecraft.
In Star Trek, "warp speed" was an inaccurate phrase. "Warp" was accurate, but "speed" was relative; "factor" is more correct. Technically, space was "warped" or bent in order to shorten the distance and, thus, allow ships to traverse longer distances in a shorter and shorter amount of time. The "warp factor" was about how much bend, not velocity (aka, speed). We tend to view the time it takes to move from one location to another location in measurements of velocity, hence the colloquial (and inaccurate) "warp speed." Thus, while warp speed may be impossible, warp factors may not be.
And you have to understand that once you reach those high speeds in space you have to spend just as much energy and time to slow down
That's right - so even if you could get a ship up to light speed, it still takes much longer than light photons to get anywhere with the time of acceleration and deceleration.
@@tombiby5892 That's what made The Expanse so good. They did their best to abide by physical laws. Which included deceleration of the space craft.

@@danmccarron0 but with more money you will be able to make more/better/new technology (faster)
@@BjarkeTaunajik Not exactly. You MAY speed up the process - but once you hit fundamental limits it will only be refinements until you have breakthroughs in theoretical work. Look at the state of theoretical physics right now....getting so esoteric so that predictions made by a theorist are verified or refuted 100 years later.
I'm not saying pouring 1000X more money into the effort won't help significantly, of course it will - but not like you think. That the hurdles are not funding, it's transitioning to new paradigms in scientific understanding and technology and if it doesn't develop independently from OTHER markets then the amount of effort is exponentially increased.
Cumulatively worldwide, the commercial tech sector (for relevant things like like microprocessor development, AI, etc) likely exceeds the numbers you have listed. These developments are directly contributive to any space program and to humanity in general, but would never factor into a NASA budget because they don't reinvent the wheel when installing computing devices in their spacecraft. The better those beccome the better everything else becomes
Another example: they discussed inertial confinement fusion here, which is outside of space program and related to commercial interests in nuclear fusion. Same idea. In many cases the technology developed for basic research (e.g. nuclear and particle physics in the 1920's) found its way into the consumer market later, but now it is the other way around. Also regarding military spending - that technology developed for warfare contributes as well.
Obviously if we stopped all military spending and had societies that made this unnecessary, and then gave everything to space explorations and related fields it would improve progress noticeably, but it's not a simple 1:1 correspondence and it may not be AS good a reallocation of funds as you think.

nickel for scale, yet 4meters to a side?? that makes no sense.
What about the kitten earlier on?
@@allistairneil8968 this confused me, too. He's saying a solar sail 1 km by 1 km (which he wrongly shows as the same length as the Ghost spacecraft that he previously said was 1.2 km long) only weighs a kilogram -- about the weight of a kitten (at 7-12 weeks old).
Earlier, he also wrongly portrayed the IKAROS spacecraft as being 14x14 millimeters (it's actually 14x14 meters!) and weighing 310 kg (that's a lot of kittens!). In fact, the IKAROS sail with support structure only weighs around 2.5 kg. The launch mass (which I take to mean the entire rocket used to launch and deploy the sail) is 315 kg.
As with the kitten, the nickel shown next to the 4 m x 4 m Project Breakthrough Starshot nanocraft is meant as compare weight, not size. (US nickels weigh 5 grams and Canadian nickels, 3.95 grams.)

@@qtclepp6860 The Volcans will tell us how to do that.
Kamikazi
If we are using sails like in the video we could use proxima Centaris light to gradually slow us down when we get within a decent distance from it so it could take an extra 2 years or so to slow down at a safe rate but it could take longer or shorter depending on how calculated the time of the slowing process begins but since it's such a small object I don't see it taking too much time to slow down due to the solar energy of the star or stars in the proxima system
And when you think how large the universe is, lightspeed is realtively slow compared to this.
That is really the fundamental problem with deep space travel. The speed of light is chump change if you want to visit anything beyond neighboring star systems and definitely intergalactic travel. You need MILLIONS of times the speed of light. And here we are, being total scrubs trying to figure out how to get things up to 2 or 3% the speed of light.

Anyone thinking how can we beat light speed doesn't really get what the speed of light really is all about (hint - its not about light & not anything like a really fast version of the speed of sound barrier).
The speed of light is in fact the maximum speed that any kind of signal or information can ripple through the spacetime fabric we all live in - it is the speed of reality - or causality. Lights travels unhindered at the maximum speed as it has no mass so that we we call it the same. It would be better to call it the speed of spacetime or speed of reality.
If you go faster than the spacetime limit you end up time travelling with a whole lot of paradox questions to face - not just a big energy bill.
If it has no mass then how is it affected by gravity?
Light isn't affected by gravity, space itself is.
so space has a mass?
@@Thesamurai1999 It's not that only massive things are affected by gravity. That's the old, pre-Einsteinian view.
Einstein said that what was actually happening was that objects with mass cause spacetime to curve. Light travels in a straight line through spacetime, but if the spacetime is curved, the "straight line" (from the photon's point of view") curves along with it.

Learning to travel through space fast is great, but it shouldn't be just about how fast you can travel, it should also be about how short you can make the distance from where you are to where you want to go.
Kinetic energy increases to the square of a velocity increase. Impact with even a grain of sand traveling at even 1/10 the speed of light would cause total disintegration of a spacecraft.
Terry Cooper Agreed. This is the complication everyone seems to miss. Even a ‘deflector’ dish, as envisioned in Star Trek, would need to project massive amounts of energy huge distances ahead through some even more esoteric method than a light speed drive.
Wow, excellent point, not 100% accurate, but a valid and real comment about space travel.
Something as small as a grain of sand, traveling at those speeds, would pass right thru a spacecraft.
However, the tiny hole it left would still cause a major problem, instant decompression.
And if it passed thru one of the crew ............
@@kbwaldron Good observation. Space is not 100% empty, a pebble the size of your fingertip can cause major damage when traveling at those speeds.
@@Saugaverse I actually tried to do an approximate calculation.
Interstellar space is pretty empty. There are no pebbles there, only microscopic dust grains, at most 500 nm in size. At relativistic velocities these do pack a macroscopic punch - basically, the energy of a bullet, if I'm not mistaken - but in order to transfer this energy this "bullet" has to be slowed down by the spacecraft. It probably won't be - it'll shoot straight through, leaving nothing but a microscopic hole.
At the end of its journey this solar sail is going to look like a sieve with billions of micrometer-sized holes per square meter - which does seem like a considerable amount of damage, tbh, but on the brink of survivability. A couple of orders of magnitude less, and it'll be fine, a couple more, and it won't make it.
