How Long Would It Take Us To Go To Proxima Centauri?

- That of one day reaching out and touching the stars is a relatively recent desire of our species...We can perhaps date its appearance to 1838, the year, that is, when the German astronomer Friedrich Bessel first succeeded in determining the distance to a star and clarifying the extent of the problem we faced.
A dream, we said,,,,, but with recent advances in technological development it seems that dream is slowly becoming a reality...hand in hand with our growing awareness of the limited resources and environmental problems we face here on Earth.
Indeed, stars are far, far too far away... But, there you go... If there were an exoplanet with some Earth-like qualities within a radius of a few light-years (not a hundred or a thousand, as is the norm) then yes, this could work!
It would do a bit like the Moon, which served as a first step, a spur to get us to the other planets... We could start seeing interstellar space as a sea sprinkled with islands, rather than as the current unreachable void.
What a pity!

If we wait 67,000 years, Proxima Centauri will only be 3 light years away from us.
:/
About 30,000 yrs
Until we are able get to Mars and spend a weekend trip to the moon, there will be no travelling to other stars
If we left today for Proxima Centauri, another human would have gotten there before us.
Will never happen
Probably will likely happen by the.n or other intelligent civilizations will discover the planet first
I'm going to walk. At 4 mph it will only take 670 million years.
I can do 5 mph but can't maintain it that long.
@@richardmercer2337 walking across nothing lol
Scenic route is to absolutely die for
I'm gonna crawl at 1 km/h. It will take me only 3,7 billion years.
walk? but first we need to get up there
Due to technological advances, any ship we send would be passed up by an even faster ship that would be developed.
The real problem is that space isn't empty. There are all manner of space rocks. To hit even a small one at such speeds would be catastrophic.
lies, i was doing fine in No Man's Sky :D
Space bigger than you think and natural objects are further apart than you think.
@@julianaylor4351 yep it's called 'space' for a reason
I suspect that due to the Oort Cloud and Interstellar Dust that nothing beyond a chip-sized craft could survive the journey.
The need for energy for propulsion and navigation make this impossible.
This video gets more insane the longer it goes on.
There is the question of surviving collisions with dust particles when you are cruising at astronomic speeds.
Neptune is 4 light hours away from us. Proxima is 4.2 light years. 4 hours (Neptune) vs. 4.2 years. It's crazy crazy far. We'll never get there.
We will. In the far far future
@@dosomestuff1949 doubt if we’ll be around on this world for long enough to achieve this
We definitely will
Humans will have wiped each other out way way way before this happening. We will be lucky if we reach Mars.
Defeatist
The problem is the same a few hundred years ago.
A ship traveling by sea would take a few months to cross the atlantic.
They tried to design faster ships but lessen the time by a fraction.
Until the day came when we travelled the air above the sea did we found out we could travel over the sea in just a matter of hours.
Point is, right now we are trying to solve the problem like our ancestors did by designing faster ships.
Maybe the answer lies not crossing the sea of space but finding a way to get through it.
Maybe we will find the answer centuries from now like our ancestors did solving to cross the sea by going over it.
Ive heard a quote from Henry Ford saying "if people were asked what they want, theyd ask for faster horses", something like that.
You could be correct in what we need is a different approach all together
Maybe like how Frank Herbert suggested in the Dune Novels to fold space and time and move from one place to another without actually moving at all.
We'd have to use the 4th dimension just to bend time and space then to make it manageable.
Well said. We have to find something that's better than flying in terms of transportation.
I notice Star Trek has it's own hyperspace extra dimension that few people discuss called "Sub-Space". The original Star Trek actually warned that the "sub-space communicators" were the basis of warp travel among other advanced ideas should they fall in the wrong/primitive hands. Perhaps Carl Sagan's "4th spatial dimension/W-Axis" exists. All the lines equal lengths, all the angles right angles.....Thinking of Warp Drive using regular 3D spatial space is no different then viewing a Tesseract in 3 Dimensions.
The "Real Warp Drive" 80 years from now makes full macroscopic use of multiple dimensions. We may be mentally as far away from that as a Roman or Moorish Abacus is from Intel 8086 Processor. (To say less of the tech feats of the i7 and i9 processor). "Any technologically sufficient civilization is indistinguishable from magic".
Religion might not beat Science per say. But Faith absolutely does. Faith triumphs all...
Let's be real here. Without FTL technology, there's no way anyone or any thing is ever going to any other star system. It's simply too far to be even remotely practical. Basically, it's warp drive or nothing. No one is going to volunteer to go on a trip that will take thousands of years, or even dozens of years, especially without any idea if there's anything at your destination worth the trouble to go visit. And who exactly would ever fund such a project that would require trillions of dollars to implement and with no possibility of ever seeing any return on their investment? It's never going to happen.
you don't need FTL. You can try to approach 90% of the speed of light for distance contraction to take place. Time will move slowly at such speeds.
However, people living on earth will have to wait so the problem of incentive to fund will remain.
The only way to work around these astronomical distance is to warp space time.
@@arijjavaid323 90% of light speed is never going to happen either. 25% would be pushing reactive thrust to it's practical limit. As speed increases, so does mass. Eventually you're going to get a spacecraft that's too massive to push any faster.
@@michaelandrew677 The good thing about space is that it's a vaccum. There are other factors such as using nuclear fusion technology to give an enormous amount of energy for acceleration of two make spaceship as light as possible as in space you don't have to worry about air resistance or overcapacity
@@arijjavaid323 Space is also not vacuum enough. At 25% of light speed, impacting a grain of sand will be like being blasted by an artillery shell. The ship will have to be sturdy enough to withstand this happening incessantly for decades at a stretch. The thing would need to be constructed like a battleship. We would need some way to deflect that space debris from the vehicle's path, or it's game over.
Then consider that however long it took the ship to accelerate to its maximum speed, it would take the exact same amount of thrust to decelerate into orbit around your destination. The challenges related to sub-light interstellar travel are just as complex as those associated with creating a warp drive. Both may be impossible to overcome, or impractical to even attempt. Which may be the reason why we don't see any signs of alien visitors.
In 2069, we will still be discussing the first trip to Mars.
Agreed
Watching this on my couch.
Tapped the armrest twice as quickly as I could, light speed around Earth.
Tapped it twice a couple of seconds apart, light speed to the moon.
Tapped it now and in 4 years, 2 months tap it again, light speed to Proxima Centuri.
A little over 4 years from now I'm quite sure I'm going to be unable to remember having ever watched this stupid video one day 🤣🤣🤣🤣
Light years are very difficult to conceptualize. Here is one way: If you drove a car from earth to the vicinity of Proxima at 60 miles an hour (24 hours a day without stopping) it would take about 46,000,000 million years to get there. You would have to have left in the Mid Eocene Epoch to arrive there today but chill the major huge dinosaurs would have died out long before you needed to leave.
I think the technology will multiply and multiply in the coming decades and really cut down the travel time faster than we could ever expect in this moment in time. There are still too many secrets to unlock in this universe when it comes physics, but I think we will start to unlock them faster than some people may think. Hopefully we'll see some cool things done in our life time!
Idk. Nothing headed in that direction currently.
@@don63 Yeah, I know, but it's just an opinion. I do believe there is suppression going on to an extent though. I think there's actually quite a lot going on. Have a Merry Christmas!
@@camerongilmour77 I get that. You're welcome to your opinion. Merry Christmas to you too 📦
no way. first off we need to evolve out the concept of intentionally killing like kind. that's gonna take at least a million years. we won't survive anywhere nearly long enough so we're not going anywhere. Look at the Orca or Sand hill crane. They do NOT intentionally kill like kind. Why? Because they've been around awhile.
I want to shoot a harpoon into a comet. And attached to the harpoon is a robot factory tethered.
The robot can line itself into the comet and go dormant.
It can wait until the comet's aphelion. It can wake up when it needs to. When the time is right it wakes up and it builds itself a launchpad... Maybe like a little radioactive microwave beam. And it is all preprogrammed so it knows exactly what it shoot off to. So it just leap frogs to the next planet moon comet asteroid etc.
And like a little hitchhikers, the robot just kinda does this over and over until it gets to say a place like Ross128b ... Okay here's the weird part.
Once it gets to Ross128b, this hypothetical AI powered probe thing, it actually has DNA and life on it.
It studies the planet's atmosphere etc. It then customizes DNA of life that can survive there and it disperses it there.
Many years ago I read a book by Issac Asimov. I believe it was title MEASURE OF THE UNIVERSE. It starts with the invisible small things to the expanse of the universe. The word "eternal" is a word with a meaning, but humans are incapable if truly grasping. For example, our bodies and everything made of matter is almost entirely empty space because atoms, protons and neutrons and electrons occupy an enormous amount of space in relationship to their actual size. The understanding of fields, whether they be energy, electromagnetic, gravity, or somethings beyond our current understanding is a peculiar problem for scientists. The Higg's boson field for example. The theory of early science that a field or condition called the Ether allow for the passage of light and energy through the emptiness of space in the universe. We now know that space is a something because it is expanding causing the separation of galaxies and all other mater. This is difficult to grasp because of the scale and size. I'll end here. This is but a taste of concepts that are finite but may as well be eternal or without end or boundaries. I'm old and have spent yours understanding concepts but I'm comfortable knowing I'm limited and amazed. The idea of traveling to our nearest star brought me to this narative. Another thought. The speed of light is instantaneous to us but unimaginably slow in the expanse of the universe. People will say they know that but in reality can't conceive its full meaning. Here something to annoy practically everyone. 99% of humanity is stupid or ignorant. We can't know everything as individuals but the problem is people glory in their stupidity and laziness when it comes to learning. Forget about wisdom. It's often highly over-rated due to bias and other shortcomings. Add people's capacity for evil, an exclusive possession of humans in this world or realm. I stray. I'm retired and have more time contemplate. Criticism is welcome as long as it's civil. God bless you and your family whoever bothers to read this. If it annoy you pretend you never read it. LOL
Yes I agree I've heard people saying that we can find a new planet if this one fails some day lol. They just can't grasp the unimaginable distance even to the nearest star!
@@bamboo59.52 I like people but most of the human race are most comfortable with stupidity. I'm near 70 and I don't give people the benefit of the doubt about most people's intelligence. Lol. The alien nonsense is an example. To traverse even our closets stars is unbelievably difficult requiring an appreciable fraction of light speed that elemental matter resist. Then there's time dilation since time slows as light speed is approached. Time is not linear or the same in relation to distant objects and is different for those objects affected by gravity. My wife and I are retired and have degrees in the sciences. No PhD but an appreciation of theory. Most people are happy being on cruise control putting as little thought as possible on most subjects. It's just the way it's always been and why we see so little improvement when things can be so much better. Like I said I like people and at peace with the way of the world. I only mention these things because you appear to have your eyes open. Not a flat eather. LOL. GOD bless you and your family.
@@rickhale4348 And you too 😊❤
Brother, I’d have coffee with you. That was a moment of clarity and wisdom.
@@thetinysideoftiny7625 I would probably disappoint you. I write my thoughts to organize what I've learned and experienced. My wife and I of 40+ years have always shared our thoughts and are much alike. Life is often a very lonely journey and having someone to share it with makes all the difference. I do enjoy, as you say, having a cup of coffee with people you can connect to and that's very rare. Getting old does allow us to contemplate our past for some meaning. We have a new granddaughter born September 1st. Our children do give purpose in the struggle of life, the love we experience with them. God refers to us as His children which goes a long way of knowing who we are. I know how much I love and care for my own family. Take care and God bless you and your family.
It's impossible for humans to travel that far...what say we try to save our planet instead !!!
Why is it impossible ? have you tried.
@@SelaphielGodsAngel even if it's possible, I'm pretty sure only the elites get to go there, while the rest of us are destined to be stuck here, so we'd better take care of our Earth instead of dreaming about something that has yet to be proven possible.
@@SelaphielGodsAngelyou have done it. Correct??
That’s fucking boring
The Fermi paradox and great filter is almost proof that this will be way harder than this video makes it out to be.
There was a study done you can see on @CoolWorlds addressing this topic. From the actual physicists paid to think about these questions. The general result of the study was that it is very difficult to populate the galaxy even if there were tons of civilizations that have come before us. It speaks on how few ACTUALLY Earth like planets there are because the Earth, our star, and our solar system, all together are incredibly rare in so many ways. You only get so much time in your solar system before your star makes it inhospitable. So if you are to survive in the long run, it won’t be because you found how to survive on Pluto. It will be because you found a replacement Earth or are able to harvest materials about your galaxy to the point you can continue to survive for billions of years. If Earth is so rare we’ll never be able to find a new home… what do we do? We can travel the stars, but every place is awful. It’s all over.
I wonder how many earth like civilizations form for how many actually achieve interstellar colonization. No way it's even 1 in a million.
@@Mnil52 well in theory if a species gets a grasp on interstellar travel it only should take a few million years to spread throughout the galaxy.
Conditioning adult humans (and babies, if it's a generational ship) to travel at such speeds and living for extended time span in space is an even bigger challenge, because however healthy they might be, it's a monstrous task to travel continuously for 4 years (at the speed of light)
No, it's not a monstrous task. It's impossible.
Food, water, air, boredom, sanity.
Let’s be real here, the chance we still have flat earthers in 2069 is far greater than us being capable of reaching Proxima Centauri…
Less than 200 years ago, we were still riding around on horseback. Now we are flying remote drones on Mars. There is no telling what we will be capable of 200 years from now...
none of us will live to see it anyways
@@douglasharbert3340 it ain’t happening in many many lifetimes if at all
You’ve got that right
@@markfroman738 it is already happening. There are talks about going to Andromeda Galaxy...
Did you really think mainstream physics was serious?
Space is a physical manifold with a vector of tension. XYZ = 2 normal pressures + 1 tension....
Distance is collapsible. How do you think UFOs get their accelerations?
Superimposable mass free energy exists, therefore mainstream is a hoax. All of it.
Great video !
If you could develop a ship that could accelerate at 1G, continually, you could get there and back to Earth in 12 years, but to the people in the ship, it would only seem to have taken 8 years, 270 days.
You would have to accelerate for half the way, turn and decelerate to get there at zero speed.....and then repeat it on the way home.
Well at least then you wouldn't have to worry about generating artificial gravity. You'd have it automatically, provided of course that you turn the ship round before you begin to decelerate.
@@rogerking7258 That's the only way you could decelerate.
Traveling by ship is the wrong idea we need a wormhole or teleportation
2069. If i'm still around to witness it i'll be 112 years old. Mmmm doubt that's going to happen somehow. I'll just have to console myself that, unlike countless millions of my fellow human beings that went before me, at least I saw the first moon landing and remember the day well as a 12 year old kid in hospital been allowed to stay up in a hospital ward in the north of England following a life threatening road accident less than 3 weeks before, and able to watch it happen.
Wait does it say a human expedition to Proxima Centauri in 2069?
Old ahh grandma
2069? Great, I'll be only 98 yrs old. I hope it's worth the wait to find out if NASA can put man into space again, let alone launch any sort of ship to a relatively nearby planet.
I'd be 108. 😁
Don't hold your breath, we haven't even been to the moon since 1972.
well they can certainly launch one. the problem is gonna be survivability. anybody making that trip is gonna catch a nasty case of DEAD. Remember that NASA nor anybody else really cares (or they would not be attempting such a STUPID thing). Space happens to be an incredibly hostile place for at least 5 very good reasons 1) no O2 2) no gravity 3) no pressure 4) freezing/boiling 5) radiation. some of these out of range will kill you very quick. the remaining will simply kill you slowly.
I'll be 93 and I somehow doubt very strongly I'll be around.
Well calm down, NASA regularly sends people into space, along with private companies, that send around 10 people collectively monthly (mostly tourists). But first stops are the moon, Mars, Venus, etc that are 0-1.5 years away. .then the areas in the asteroid belt, rocky worlds like Ceres and Vesta about 2 years away. And then it's Europa, Titan, and the rest of those words that are about 6 years away...then the areas in the asteroid belt, rocky worlds like Ceres and Vesta about 2 years away. And then Pluto, Triton, Neptune, etc - that are about 14 years away but much less if we launch the expeditions from a city on Titan for instance.
Colonizing those outer-most planets open the doors to interstellar travel. Where basically, launching from Neptune/Triton/Pluto, and then going to a rocky dwarf planet beyond the heliopause and in the oort cloud...where you are officially no longer in the solar system. Budget interstellar travel is our only option...Proxima Centauri is literally hundreds of thousands of years away if we just sent a ship now (uttermost pessimistic estimate) but tech will probably advance exponentially in this field enabling expeditions to be sent in just a few hundred years.
These planets, Proxima Centauri B for instance, are in true interstellar space (or well, beyond our system). Landing on a rocky world, temperature very mild maybe between -30 and 30 degrees. If it has an atmosphere, we're set.
I love this mans voice. Reminds me of binging strange mysteries during the winter in 2016. Here we go again babyyyyyy.
We aint leaving this here Solar System anytime this Century! We are threatening our own survival right here, right now. How about solving first things first?
Gets in the way of profit.
There are human beings that wake up every day not being able to figure out what gender they are. We need a new planet, and leave those people here....
I think we better start focusing on bending space, testing black holes and such to get to these great distances although it's promising technology to reach 40% the speed of light or more over the next 1000 years, something generations down the line can enjoy exploring
Lots of wars likely over the next 1,000 years. Some may be nuclear. Just saying...
Solar Sails sort of reminds me of Count Dooku's ship from Star Wars. A ship like that irl would be pretty cool.
This guy gets it
Presumably bases could be built on the outer planets. The ice balls beyond Pluto. Get there by "island hopping". That star should have similar ice balls.
Can we do how long to get to Trappist -1 system next?
Not for you
So, if I traveled about the speed of 22,000 mph, I'd get there in only 142,045 years. Sounds good to me! 😂
Seems like we're right on the verge of getting there. Can't wait!!
You are correct. You can’t wait………at least not long enough!👍
2:55 The star on the right is Beta Centauri. The two stars of Alpha Centauri are too close to distinguish in this picture.
My biggest question is always: how would we slow down a probe or ship from 10-40% the speed of light? Would need some sort of thrust but if a probe with only a sail heads out, how would it slow down?
Sails are only meant to fly by and take photos and record data in the quickest most efficient way possible. It would take way too much mass, energy, and time to slow them down at that speed.
You're assuming current technology. Its pretty obvious that we require a gigantic plan B.
Gravity for some of the braking?
@@charleshendry5978, this is the only possible way I can imagine too: because all probes sent away from Earth into deep space achieved their current speed thanks to the use of gravitational leverage through the outer planets of the solar system, especially the most massive Jupiter and Saturn, a process which would need to be repeated when entering the Centaurian planetary system, if it really exists, and in the reverse order performed for the leveraged acceleration. BTW I wonder if such leveraged acelerations could be performed in sequence to make it possible to achieve at least 10% of the speed of light. 😢
Shows just how important higher level math 🧮 skills and knowledge are to leave this planet 🌎 in a physical form. Thank you to all the math and science 🧪 teachers out there who need to be compensated up to half a million dollars a year.
I think so but maybe in like 1000 years. If we cant invent some kind of antigravity or space bending then it will have to be a superfast spaceship with a huge force field in front to vaporize/deflect small objects
So all we need to do is build some Bajoran Solar Sails.
Is that what sisko and his son use in that one episode?
@senorpepper3405 It was yeah.
What's the point of going if there's nowhere habitable
1. It is important to keep in mind that a trip across 4+ light years of space cannot afford even the slightest deviation otherwise you are going to miss your target by light years.
2. Given how long it takes simply to travel from the Earth to Mercury it is quite impossible to travel from wherever you might end up in the Proxima Centauri system and reach any of its planets.
3. It is absolutely impossible to attain orbital capture by another star after you have escaped orbit around the sun. The amount of energy you travel with is irrelevant.
4. Suppose you did attain orbit around Proxima Centauri your initial orbit around that star is cometary and therefore you are going to spend at least 100,000 years on your initial orbit. It will be quite dull but don't worry you aren't going to survive that long in interstellar space anyhow.
Yes... Finally some logic in these proxima related videos (and comments)... Also another additional "setback": who in his sane mind (it has to be sane mind, as sending lunatics won't help the cause at all), would abandon this paradise of a planet, to travel to a (probably) Mars like dead rock of a planet, being bombarded with star's radiation, having to live either in constant dark side or planet, or in "middle zone", where you will never have normal bright day, and constant "sunset" , in a 1 way trip (returning won't be a option anyway)... Who? I think no sane human will go there... Even going to Mars is questionable, as it's much much worse planet than our own.
Obviously there are no straight lines in space either. You have geodesics. I not sure the navigation aspect has really been worked out. Course corrections would require enormous energies.
Not with that attitude we won't.
@@Malfurionxtc
Yeah but space is cool so we should go there.
@@cat_city2009 You go, I'll stay here.
Makes my mind boggle and cry like a baby thinking just how large outer space is and is virtually infinite.
Freeze me and defrost me in 40 000 years once we master that technology.
I feel dizzy…
The vastness of space is unimaginable.
We can build a hieghliner and using the holtzmen effect fold space and giving the guild navigators melange to get us there safely !
Let's say the crew reached the planet, it would take 4 years for the signal to reach Earth to confirm a safe arrival, then 4 years for mission control to respond. If the crew had an issue on arrival, it would take 4 years for a message to reach Earth. It would also have to be a one way trip because by the time the crew got there after 30 years for example, the round trip would be almost a lifetime. They'd have to leave by at least 20 years old minimum to make it worth the round trip for them to get back by 80 years old and in the hope they didn't get any illnesses or injuries on the way 🤣
No. While what you are saying is true it is quite impossible to send a radio message of any sort from Proxima B to the Earth, nor to send a radio signal from the Earth to Proxima B. There isn't enough energy on the Earth to attain the wattage necessary to send such a message and a probe would miss that target by at least a thousand orders of magnitude.
@@sentientflower7891 Yes. They would have to find ways to piggyback signal on beta/gamma particles to send "messages" to light years away I think.
Quantum entanglement
Plus everyone they knew or loved would be dead by the time they got back!
@@bamboo59.52 this is a mistake commonly made by science fiction: there is no return trip possible from another star. You could actually have to complete a revolution of the Milky Way before another opportunity to return to the sun. See the Mars missions for a similar problem in returning requiring a complete orbit.
traveling at the fraction of speed of light sounds great, but...
How to we pump the breaks when we get there??
Going to the moon in terms of space travel is like going from your bed to your couch in your living room, and even that is way too much to precisely describe how vast distances are in Universe.
Choose the cigar shaped spacecraft, it only takes few seconds to go there. All others are much slower.
Jan luc Picard would simply say, engage!
I really enjoy these videos, I finally found a great channel
When the crew is halfway to Próxima Centauri and mankind has just locked quantum portal hopping to skip them in line 😮
38000 years? What if I have to pee?
I'll be 86 in 2069 and they will say "we have to delay the launch until 2075"
I'll be like "wtf, guys?"
What if we had an energy source that could accelerate at .9G until we were 1/2 the way there, then decelerate us at .9g the second half? How long would that take, and how fast would we be going at the halfway point?
c = lightspeed = 3.00E+08 m/s
1 lightyear (ly) = 9.46E+15 m
D = distance between Sol system and Proxima Centauri system (4.25 ly) = 4.02E+16 m
Δx = D/2 = halfway point; midpoint; turnover distance = 2.01E+16 m
g = gravitational acceleration at Earth's surface = 9.81 m/s²
a = starship acceleration = 0.9 g = 8.83 m/s²
v0 = initial velocity (from geostationary orbit around Earth = 3,139 m/s
Δx = distance to turnover point = 2.01E+16 m
v1 = final velocity at turnover point = to be determined
(v1)² = (v0)² + 2aΔx
v1 = √[(3,139 m/s)² + 2(8.83 m/s²)(2.01E+16 m)]
v1 = 5.96E+08 m/s = 1.99c
It turns out that, in a non-relativistic calculation, an acceleration of 0.9 g over the distance of Δx
(2.125 ly) gives a turnover velocity that is greater than lightspeed, an obvious impossibility. So,
the parameters will have to be adjusted. Using the same turnover point, let's see what is the
maximum attainable acceleration.
v0 = initial velocity (from geostationary orbit around Earth = 3,139 m/s
v1 = final velocity at turnover point = 0.1 c = 3.00E+07 m/s
Δx = distance to turnover point = 2.01E+16 m
a = starship acceleration = to be determined
(v1)² = (v0)² + 2aΔx
[(v1)² - (v0)²] = 2aΔx
[(v1)² - (v0)²]/2Δx = a
a = [(v1)² - (v0)²]/2Δx
a = [(3.00E+07 m/s)² - (3,139 m/s)²]/2(2.01E+16 m)
a = 0.0224 m/s² = 0.0023 g
An ion-drive constant-boost starship should certainly be able
to sustain such a modest acceleration.
The time required to reach the turnover point at a = 0.0023 g is . . .
v1 = v0 + at
(v1 - v0) = at
(v1 - v0)/a = t
t = (v1 - v0)/a
t = (3.00E+07 m/s - 3,139 m/s)/0.0224 m/s²
t = 1,340,139,777 s = 42.5 y
The same amount of time would be required to decelerate, which means that
a one-way trip to Proxima Centauri would take 85 years.

Our bodies are not designed to be under that type of G forever. Even 5 minutes of excessive G is a real test of survivability. how would we eat, pee, sleep that sorta thing? not gonna happen we are way, WAY too fragile. basically think about a balloon filled with gelatin. yeah, that's us. hell we can't even fall 6-7 meters without killing ourselves.
More than a hundred million moons lengths really puts things in perspective man
Even if we somehow come up with a way to accelerate spaceships to a healthy fraction of the speed of light to cut down the journey time to a reasonable figure there is another problem I rarely see addressed. That is the possibility of collisions with objects in space. After all we have to worry about space debris colliding with artificial satellites in Earth orbit. An impact of even a very small object could cause serious damage considering the speed would be on the order of a few kilometres per second. If a spaceship travelling at 10% the speed of light collided with space debris the damage would be catastrophic. Space is largely empty but you never know when you will encounter an object during space travel especially when travelling at very high speed.
It’s insane considering it takes only seconds for light to circle the entire earth, imagine that speed in distance over 4 and a half YEARS. It’s almost unfashionable when you think about it
In one second, light circles the entire earth 7 times
Unfathomable too.
Photons have no mass.
You have been proposing how to go to Proxima or that ALiens going to Earth ,what transport did Aliens from Proxima used to travel to Earth? Aliens of 7 from that Proxima reached Earth in 1961-62. How is that?
I would love to think that upon our maiden voyage, about 2 generations later the captain of the ship sees a strange signal approaching from behind. And it’s us on a spaceship designed to extract all of the maiden voyage humans and their colony starter kit, then BOOM! We are all there.
And just what's so important or? interesting about Alpha Centauri that'd make it worth our while wanting to get there is it an exo planet? that may be used as a 2nd home for humanity and more importantly what happens to us if we get there only for the star 🌟 to go supernova would we be in direct danger of being destroyed by a black hole??
Let not go that far to a dead planet, when we have a dead planet, Mars, so much closer.
That probe without any propulsion except tiny gas tubes accelerating that much got me thinking that an actual interstellar ship could be significantly faster. Problem is how do we solve the problem of space dust collision?
for observation from the Earth, it is enough to adapt virtual reality glasses - a 3 D oculos to the orbital station around the planet Venus, at the same time, simultaneously solving the thermal problem of the Earth of CO2 accumulation in the Earth's air atmosphere
We haven’t even sent humans to Mars let alone another star. The problem now a days is planning is pushed out way too far. During space race to moon It took eight years, 10 practice-run missions, more than 400,000 engineers. This was doable. Otherwise figuratively speaking it’s just a pie in the sky.
If you have a sail accelerated by a star (our sun) the star you are approaching will cause deceleration at the half way mark.
i think the Daedalus project is the most realistic option for me.we should do more research on it.
We just need the key. It will come at some stage.
If we can fly 13% of the speed of light is like when Pac-Man game starts, he runs right into the ghost monster
Those Aliens met Sps. BARNEY AND BETTY of New Hampshire way back Sept of 1961 to 1962.
I'm working on a DnD scifi setting where ppl can reach part-lightspeed (like 20-40%), and are working on improving the wellbeing of passengers who have to travel for decades sometimes. Edit: good on you who thought "cryosleep", but in this setting, cryosleep is still work-in-progress and kills or cripples about 1/3 of whoever attempts it.
6:08 In the movie Passengers spaceship Avalon used this propulsion. 😁
Pity it was such a bad movie. Someone should rework and remake it.
you need to start for the experiment, for starters, as an experiment from the planet Venus, gradually changing the air environment on the planet VENUS to a more favorable earthly environment for human habitation
Only 13 minutes and 27 seconds, if you travel at Insane Curiosity velocity.
Spooky action at a distance. That'd work.
Quantum entanglement could really change the game for long-distance space travel
Yep.
I can see transporters in the future.
Maybe that where all these uap's are coming from....Lol.
Taking the shortest path out of our solar system traveling at earth speed velocity on a direct intersect course towards Proxima Centauri. Once separated from our solar system moves away at its galactic speed from the spacecraft and Proxima Centauri heads toward our spacecraft at its galactic speed will reach it in how long?
The Eurostar obviously 😅!
It's not just the speed itself, it's the integrity of the ship. How do you travel that fast without tiny space dust from absolutely eviscerating the ship? Never mind the stress of achieving such a velocity, and the trauma on human beings accelerating and deaccelerating.
Plan B is to accelerate/decelerate every atom at the same rate as the ship the entity is traveling in. in essence one can't be something within the ship they must be the ship itself. We're at least a million years away from evolving to that point... IF we survive intentionally killing ourselves of course.
There wouldn't really be a trauma, humans (astronauts) travel 8km a second without feeling it since the rocket slowly powers up
@@mymixedbiscuit9159 Right, if they gradually accelerated it would be fine, but a sudden stop would be beyond catastrophic.
Exactly, how do we avoid hitting something? Your ship would have to be ultra sleek but you'd still take damage.
A force field of course
Its the coming back when you find out its not inhabitable after all
In the back of my mind I hear her familiar voice...
"Frame shift drive charging"
Fly outside of rush hour would be a good idea.
Waiting till 2069 would mean 45 years from now. So most people watching this video would no longer be alive.
Id be happy to see a science station on the moon, and thats a long shot.
However long it takes, it'll be quicker than the length of time it takes my girlfriend to get ready for a night out!!🙄
These kinds of engines sound extraordinarily complicated. what happens if we get halfway there and they malfunction and break down?
It's a long way back to Earth to retrieve a spare flux capacitor.
The difficulty is not being able to travel at the speed of light or even 50% of the speed of light, but rather being able to stop in the right place. A few more seconds and they will end up on the other side of the galaxy. According to what I heard a few years ago, I can't say for sure if it's true, the Concorde on its furthest journey started to brake halfway through the journey. On an 8-hour trip, I would only travel at maximum speed for two hours. One part of the time was acceleration and the other part was deceleration.
The ridiculous time spans required and the huge distances involved will ALWAYS make interstellar travel impracticable. The Fermi Paradox is no paradox. There may be lots of intelligent civilisations in the universe but they are all hopelessly isolated by the gigantic size of the universe and, you know, the laws of physics. No two such civilisations could ever interact with each other.
Traveling even to the nearest star system seems so unpractical or unfeasible using any form of physical propulsion, so I strongly believe that practical ways to travel interstellar distances only will come after humanity masters the inner workings of space-time, and can develop propulsion systems that bend space-time in order to short-circuit the journey between any two points.
No alien from other stars will ever reach us. If we are lucky, we probably might find their version of voyager 1. Long after their extinction
C’mon brainiacs we got this,lets go Warp drive engines now Go!!
Well, however we go to the stars one thing is for sure, we are always going to be fighting and killing each other. It's in our nature.
Until its figured out how to get ships carrying humans, i liked the idea i heard of a drone like object. Something with a camera and so light it can travel on a laser beam, and send it at speeds we can't travel at yet.
…need a power source and ship for the Alcubierre Warp Drive (yes, there is such a thing)
Let's assume we'd travel at 30.000 miles an hour, it would also take 186'335 x 3600 x 24 x 365 x 4,37 / 30'000 x 24 x 365 = 97'714 years. Any further questions?
If Ensign Hoshi Sato called from there and says 'Come over, my parents aren't home' ?
About an hour, give or take.
And people are surprised we've never seen aliens...
Wait, if we can figure out how to create one winning lottery ticket then surely we have the brain pans to travel beyond the moon
Once we have a ship that can go a trillion times faster than the speed of light, we'll be all set. That technology is just around the corner.
Wenn die Sonne so gross wie ein Golfball wäre,wäre Alpha Centauri etwa 700 Meilen weit weg.
This video is super hysterical as long as it's purely satire. If it's not satire, it's even funnier 😝
If a robot wanted to travel to Proxima then it could send a Von Neumann machine to an orbiting planet then have the robots mind turned into a digital code which is then sent to a newly built robot on the Proxima planet.
