Not to mention the unanswered potential issue of hitting particles of matter. Even very light such particles would have devastating impact on rockets traveling at speeds in the order of 0,1 c. One mustn't rule out the presence of such particles (let alone larger objects such as meteorites or comets) in interstellar space on the basis of gravitational "depletion". For instance, the frequency of rogue planets recently evidenced took astronomers by surprise. For the same reason that large objects such as planets or planetoids are more frequently found than previously suspected, the occurrence of smaller objects with considerable momentum is highly probable and should be considered and adequate protective measures found to avert catastrophic collisions. With velocities in the order of magnitude of those envisioned for rocket propulsion by atomic explosion or any version of it, even "tiny" objects would carry momentum with monumental energy of impact. This problem is surprisingly ignored in many discussions of interstellar travel.
@@raminagrobis6112 exactly! It's crazy we now actually KNOW HOW to get a decent way to the speed of light, the issues now become what to do to survive going those speeds.

We’re already developing laser weapons on Earth. U would need that kinda tech on the ship. Or in the case of Orion, the pusher plate should be durable enough to withstand the smaller impacts. For bigger objects, more advanced sensors could give u a means of avoiding them. Better than having to built something that could withstand the impact.

I disagree with your conclusion that had we not shifted priorities after Sputnik, we could be in the Alpha Centauri system now, reading our ipads and playing frisbee with the family dogs. Sorry, but making such a trip through deep space radiation? And lack of gravity? Though we could be talking about sending a probe to Proxima Centauri with nuclear powered propulsion, the human body is not currently capable of making such a trip. We'll have to devise technology to shield reliably against radiation (human-made magnetic fields are a possibility) and to create artificial gravity. The centripetal force systems we have envisioned for 1-G interfere with balance and blood flow, unless we could build them about a mile in diameter. That's a whole new mountain to climb. And just what do we know about the exoplanets of which we have seen indications? Just indications - that's all.
If you lived on the other side of the Milky way Galaxy and you could travel at 10% the speed of light, it would take you 800,000 years just to get here, not worth the effort don't you think 😉?
17:40 They really should make an unmanned craft, to go there, either fast track a some bombs, for the "pulse nuclear drive. or use/modify the ones we have. It only take a couple years to get data back from that far, we could have video of the surface of the planets, in as little as say 30 years from now, 20 maybe.
I'm wondering if after a place is setup on the Moon, we could make and use nuclear propulsion. Because it won't be launched from Earth. There we could build a larger spaceship and fuel it with nuclear. Also isn't there talk of trying to form a bubble in space and time to move through space more easily and faster. I think this is our time to explore more space. I'm glad to see more enthusiasm for this endeavour. Viva la space.
Yeah, launching nuclear propulsion from the Moon could be possible due to its lower gravity and lack of atmosphere, making it easier and safer than Earth launches. Building larger spaceships on the Moon is also feasible in theory, but we need more infrastructure and technology. The concept of a space-time bubble, or warp drive, is still theoretical and highly speculative.
I agree with you. There is also far too little information about conditions on Alpha Centauri to justify the likely expenses of travel from Earth. I think of basics like atmosphere, gravity, and whether we would be able to grow anything in the soil.
@@bdetert82This looks all nice and simple on paper, but we tend to underestimate the extremely problematic fact that any planetary system further away from the Sun than Earth gets ever colder, and all moons with water and/or characteristics compatible with human life are so cold that living entire lives in the confines of heated compounds - not to mention the extra need for protection from radiation in all moons without a magnetosphere - presents potential difficulties we have never even addressed technologically. We're talking about temperatures colder than nitrogen boiling point here. I'm not saying that the problems of living in heated confined places with drastically steep temperature gradients inside - outside are insurmountable in theory. Only that we have never been confronted with dealing with the problem in actual space exploration. I'm sure that systems based on current habitation in Antarctica are currently tested for more extremely cold environments right now. Just mentioning that we have not officially tested the survival of humans in environments as cold as Europa or Titan.
@@raminagrobis6112 I do think the moon is the best option. You have essentially the same stuff that makes up earth. But with a fraction of the gravity. but trying to industrialize the solar system from earth based resources is not sustainable.
Sci- fi is awesome to read or watch in movies and tv. Too many people believe it is the actual future. Unfortunately, there's more fi and less sci in it. I believe we're stuck here on earth, and better get used to the idea.
you dont need a ship or lightspeed to travel you use quantum field travel array you clone here it will send it instantly anywhere in the universe without leaving. so your in 2 places at the same time.
WHAT? It's grossly premature to talk about colonizing the Alpha Centauri system today given that Voyager 1 is less than one light day from Earth. The Alpha Centauri system is over 4 light years away. Humanity hasn't even established a colony on the Moon, on Mars, or in the nearby interplanetary space. Before colonizing the Alpha Centauri system is on the table, how about colonizing our own solar system, establishing a network of telescopes in the sun's gravitational lens region, and finding a way to travel interstellar distances in a reasonable amount of time? Taking at least 10,000 years to traverse one light year just doesn't cut it.
The answer, very simply, is no. Even IF we could speed up the trip to something on the order off 10% light speed - so a mere 43 years one-way, first of all, there IS no return trip - you'd be dead before you got back even if you turned around right when you got there. At a minimum, any astronauts sent on an initial trip would need a college education - so likely they'd be at least 22 after Bachelor's and let's face it, it's NASA or its equivalent, so an advanced degree is minimum - Master's or PhD. Realistically then candidates would be, upon graduation, 24 to 29 years old depending on program length and whether they did a 1 or 2 year Master's, or added a PhD (5 years is typical) after that. Say 26 as an intermediate. 43 years later, assuming they left RIGHT after graduating, they'd be 69 years old upon reaching Alpha Centauri, probably closer to 70 (distance 4.367 light years / 10 = 43.67 years). Also, it'd take even LONGER than that because you'd have to start slowing DOWN long before you got there and build UP to that maximum 10% light speed. So you'd have a bunch of cranky old people arriving in a star system we know next to NOTHING about, expected to survive, where? THAT's the other key thing here: we're ASSUMING the planets in that system would be even remotely compatible with human life. We simply have NO way of knowing that. We can loo at spectral data, things like that for clues as to what ELEMENTS are present, but determining exact atmospheric makeup, geology, what sorts of hostile viral lifefforms may be present, how often the planet is smacked by big asteroids or gamma rays, these are not things we can TELL from earth. We don't even know for sure if the human body can TOLERATE the rigors of interstellar travel, we can't guarantee any objects wouldn't be in the WAY of our ship that even with a shield would destroy it. There are MILLIONS of variables we don't KNOW about, so ANY trip there would be a blind one at first. Realistically, before risking human lives on a 40+ year one-way trip (if it's a generation ship, even worse - maybe you take centuries only to get there and realize you CAN'T survive there - and then there's the ethics of giving birth to someone in space, so that they are born in a can in space and are forced to spend their entire life trapped in that ship) - you NEED to send scouts in advance. SO, we'd need to maybe send some LIGHT SAIL mini probes that can get up to let's say 30% light speed - low mass, tiny things propelled by giant light sails - the tinier the better because it's not a practical technology for a big ship - too heavy - get them there in, let's say, 15 years - the SIGNALS we get back take 4.36 year so about 19.5 years from launch to when we get our first up-close data back. And you'd want to send TONS of the little things, not just one - because you need to maximize the amount and KIND of data we get back so that we're not going to have to wait ANOTHER 19.5 years to send more if we miss anything, they run out f power, get destroyed on the way, malfunction, etc But to even DO this you also need to build basically a giant laser - maybe on the moon - that is aimed at the sail of each one to give them an extra push - very time consuming, expensive, and requires lunar construction bases. At MINIMUM, even if we started NOW, it'd be 20, 30 years to get the PROBE swarm capable of those speeds, the lasers built, dozens to hundreds of mini-probes launched and built, at a massive cost the public would complain about. THEN we wait almost 20 MORE years for the data back - so 40 to 50 years is the BARE MINIMUM (2074) for when we'd even have an ANSWER as to whether any planet in that system is truly habitable and exactly what we'd need to bring to survive there. THEN, because you DON'T want the colonists arriving with nothing set up to manufacture oxygen, water, etc , you'd want to launch a series of BIGGER missions designed to LAND on that planet with supplies already on-board - they'd start automatically growing plants they have brought with, producing breathable air (because chances are next to zero another planet just HAPPENS to have our exact atmospheric composition WE evolved to breath - 21% oxygen, mostly nitrogen) - and Those would be slower than the much lighter probes, realistically - maybe 10% light speed - so THEY'D take 43 years. ANd you'd HAVE to wait until they were down on the ground and operating for a while because yu do NOT want to send a bunch of people on a one -way trip to and the planet only to realize upon arrival the critical systems they needed crashed or stopped working. You COUD send a really BIG ship - but the bigger and heavier it is the more power you need to accelerate it to 10% light speed (any faster than that with our current science is not likely) - and the technology would be then UNTESTED on that new world. Which is bd. You want to take NO chances with that, so make SURE it works, before you even THINK about sending human beings. SO, we have 2074 for a minimum time to design, build and launch a swarm f mini-probes, get the data back, if the data is a green-light on human habitability, sending the advance ships (unmanned) with all the machinery and so on they'll need upon arrival, and start that running. You'd want it running at least, say, 10 years without issue before you'd ACTUALLY send manned ships. So 2084, MINIMUM date for sending MANNED ships. It arrives, assuming 10% light speed - in 2127 - a bit over a century from now. We don't know whether they SURVIVED the trip or not until 2131 minimum (takes the message that long to get to us). We send a "received" message - they don't get that fr another 4.36 years, close to 2135. Any messages and updates from THERE would also take over 4 years, 8.7 years round trip. Communication would be VERY slow, so they'd be on their own, knowing if any help COUD be sent, an SOS takes 4.36 years to get to earth and a mission to them takes over 40 years to get there - by which point they'd a be dead. And that's not even considering the cost an difficulty of building giant moon lasers, light sail probe swarms, the advance ships, and the final MANNED ship, which wouldl be huge and likely take DECADES to build. It's hard and expensive to transport even SMALL things into space - so you'd be looking at a LOT off very expensive launches - meaning a MOON base is likely needed FIRST, one which is permanently staffed AND has its own refineries and mean to make metal ad wiring and everything you'd need. THAT realistically won't happen for many decades at our current pace. But there you have it. REALISTICALLY, we're looking at an EARLIEST arrival time of nearly 2130. But given our ACTUAL pace of development and the lack of motivation in governments or funding for such a thing, it could be 500 to a thousand YEARS before we ACTUALLY got around to it. I mean, we're just NOW talking about sending people to walk on the moon again - over FIFTY YEARS after the last man walked on the moon. You'd need a concerted multinational effort to do this on a time scale that'd even get us there by 2130 - funding and all - and THAT, I'm afraid, is very, VERY unlikely unless a planet-sized asteroid we can't divert the orbit of in time due to its sheer size were hurting toward the exact spot earth will be at in 2150 or so and we KNOW for SURE that earth WILL be destroyed by it at that time. It'll take an existential crisis like that to FORCE powers that be to MAKE it happen even in the next 100 years. Without that push? Centuries, maybe thousands of years. WHICH, by the way, MAY be a big answer to the Fermi paradox - you don't see aliens flying around the galaxy colonizing worlds simply because the whole thing is too hard and takes too long and civiizations die off before they ever muster the motivation to actually do it, be it by nuclear war or something else.
Yes, unmanned probes would be the only way. With both distance and time a huge factor, and the likelihood of finding nothing even remotely habitable upon arrival, a manned mission would not be feasible. I can't imagine even the most dedicated astronauts and scientists being willing to spend their entire life in an oversized tin can hurdling through space just to reach an uninhabitable rock to take some pictures of and send back right before dying of old age. Until technology improves exponentially no humans are leaving the solar system anytime soon.
The first is that it will take twenty to thirty thousand years to get to the Alpha Century. First of all, Alpha Century is 4likers away from our world. So go there and dream about it far away, we may be unemployed
Good information. Very interesting stuff. However, there probably is not much in Alpha Centauri worth sending humans to. Proxima B is probably more similar to Mercury than it is to Earth.
Yeah I’m all in on using the Orion design to safely deliver probes to the system. The interstellar versions of Voyager if u will. It’d nice if the ship could make these probes but at the worse, the ship is just the mail truck.
The effort is there. The material and engineering aspect is where we’ve been stuck. Solar sails aren’t new tech. If we’d put the effort into NPP tho, we would be about 20 years away from a flyby.
It’s not enough for reps to show up. If you rep 6000 workers, those 6000 workers should be there. That’s what solidarity means. It’s not the same as “we wish you good luck as you take in the fascist state.” 💖😘
It's one thing to dream up an idea, and another to build it. It's also one thing to propel a rocket to 10% of c: that's a tremendous accumulation of kinetic energy! Now imagine an object in your path, say only 100,000 km away. You have a little more than 3 seconds to avoid it. If you don't, then it also has a relative speed (relative to you) of something close to 10% of c. Now imagine the kinetic energy turned into heat and destruction during the collision. It's definitely another thing to imagine how to prevent that! But space is big, you say, and matter is scarce. What could happen in only 40 years? Starvation? Asphyxiation? Radiation poisoning? Or maybe alien intervention? 🤣 Yeah, the last one is unlikely, so I guess the others must be too.
Problem is, better designs have already been conceived. Designing and building are two different things. Anything we talk about was already discussed in the 50s but the with the tech at the time, NPP was(and still is) the most feasible. Plenty of videos about Solar Sails to know that building one that could withstand the thousands of micro-meteor impacts is a doozy lol
4 years we can be there. The Q is How can we see on the surface Sending a holagram from sun heat solar laser moon mirrors particles light energy crystals
Would there not be a Lagrange Point between Proxima and the other 2 stars to park our ship opposed to trying to directly stop at Proxima b? Shed speed using the other 2 stars, park on the outskirts of Proxima and then go from there?
It won't be. Most likely it is an uninhabitable tidally locked rock scorched on the side facing the star from solar flares, and frozen on the side facing away from the star.
Who the hell cares if we can build a machine to go to a distance place? The real problem is that humans would never survive a long journey in outer space.
We cant even easily travel to the moon yet, let alone to another solar system lol if we are lucky, if we dont self destroy in a nuclear war, we maybe, MAYBE will colonise the moon and mars just maybe by the end of the century

17:40 They really should make an unmanned craft, to go there, either fast track a some bombs, for the "pulse nuclear drive. or use/modify the ones we have.
It only take a couple years to get data back from that far, we could have video of the surface of the planets, in as little as say 30 years from now, 20 maybe.
I'm wondering if after a place is setup on the Moon, we could make and use nuclear propulsion. Because it won't be launched from Earth. There we could build a larger spaceship and fuel it with nuclear. Also isn't there talk of trying to form a bubble in space and time to move through space more easily and faster. I think this is our time to explore more space. I'm glad to see more enthusiasm for this endeavour. Viva la space.
Yeah, launching nuclear propulsion from the Moon could be possible due to its lower gravity and lack of atmosphere, making it easier and safer than Earth launches. Building larger spaceships on the Moon is also feasible in theory, but we need more infrastructure and technology. The concept of a space-time bubble, or warp drive, is still theoretical and highly speculative.
@@InsaneCuriosity Thanks for the reply
We need warp speed Scotty😂🤣
We can't even get to 0.01 percent the speed of light
@@ps3301 Wrong. Actually we rached 0.05% of the light speed. Parker Solar Probe reached 163km/s.
3:35 that sounds like the Orion drive?
More like the "in your dreams" drive.
They don't even know if it's habitable
Eeee, should we begin with the moon and mars first?
No point going to alpha as no viable planet's their.
I agree with you. There is also far too little information about conditions on Alpha Centauri to justify the likely expenses of travel from Earth. I think of basics like atmosphere, gravity, and whether we would be able to grow anything in the soil.
Im guessing there would be many cascades of malfunctions before long. It would be the Mike Bay version of space travel.
That flat metal plate would turn to slag after a short while.

I don’t think I’d like to go it’s a three star system visions of the three body problem come to mind.
Too bad the narrator sounds like Casey Kasem. Medi school makes them sound all the same .
Is there a radio dj school
You know 2069 is right around the corner...
We could already be on our way if Project Orion had got off the ground!
Best astronauts in the world are inmates whom have been in isolation for more than 10 years etc.
How can we Colonize a world we cant even go to with todays tech.. maybe we should start by maybe getting man to mars first.
Well at least a colony on the moon would be helpful. Easier to launch from there.
@@barracuda861 Moon or Ceres. Once you have a Low g manufacturing base the entire solar system is habitable.
@@bdetert82This looks all nice and simple on paper, but we tend to underestimate the extremely problematic fact that any planetary system further away from the Sun than Earth gets ever colder, and all moons with water and/or characteristics compatible with human life are so cold that living entire lives in the confines of heated compounds - not to mention the extra need for protection from radiation in all moons without a magnetosphere - presents potential difficulties we have never even addressed technologically. We're talking about temperatures colder than nitrogen boiling point here. I'm not saying that the problems of living in heated confined places with drastically steep temperature gradients inside - outside are insurmountable in theory. Only that we have never been confronted with dealing with the problem in actual space exploration. I'm sure that systems based on current habitation in Antarctica are currently tested for more extremely cold environments right now. Just mentioning that we have not officially tested the survival of humans in environments as cold as Europa or Titan.
@@raminagrobis6112 I do think the moon is the best option. You have essentially the same stuff that makes up earth. But with a fraction of the gravity. but trying to industrialize the solar system from earth based resources is not sustainable.
Sci- fi is awesome to read or watch in movies and tv. Too many people believe it is the actual future. Unfortunately, there's more fi and less sci in it. I believe we're stuck here on earth, and better get used to the idea.
you dont need a ship or lightspeed to travel you use quantum field travel array you clone here it will send it instantly anywhere in the universe without leaving. so your in 2 places at the same time.
A 40 year one way trip to certain doom is not ok.
WHAT? It's grossly premature to talk about colonizing the Alpha Centauri system today given that Voyager 1 is less than one light day from Earth. The Alpha Centauri system is over 4 light years away.
Humanity hasn't even established a colony on the Moon, on Mars, or in the nearby interplanetary space.
Before colonizing the Alpha Centauri system is on the table, how about colonizing our own solar system, establishing a network of telescopes in the sun's gravitational lens region, and finding a way to travel interstellar distances in a reasonable amount of time? Taking at least 10,000 years to traverse one light year just doesn't cut it.
Not to mention the damage to the environment of the planet. Trying to use nukes to propel a craft in atmo would be bad.
someday the humanity will colonized toward the exoplanet...but not today.
No. As another video on this channel states, humans will never engage in interstellar travel.
The answer, very simply, is no. Even IF we could speed up the trip to something on the order off 10% light speed - so a mere 43 years one-way, first of all, there IS no return trip - you'd be dead before you got back even if you turned around right when you got there. At a minimum, any astronauts sent on an initial trip would need a college education - so likely they'd be at least 22 after Bachelor's and let's face it, it's NASA or its equivalent, so an advanced degree is minimum - Master's or PhD. Realistically then candidates would be, upon graduation, 24 to 29 years old depending on program length and whether they did a 1 or 2 year Master's, or added a PhD (5 years is typical) after that. Say 26 as an intermediate. 43 years later, assuming they left RIGHT after graduating, they'd be 69 years old upon reaching Alpha Centauri, probably closer to 70 (distance 4.367 light years / 10 = 43.67 years). Also, it'd take even LONGER than that because you'd have to start slowing DOWN long before you got there and build UP to that maximum 10% light speed.
So you'd have a bunch of cranky old people arriving in a star system we know next to NOTHING about, expected to survive, where?
THAT's the other key thing here: we're ASSUMING the planets in that system would be even remotely compatible with human life. We simply have NO way of knowing that. We can loo at spectral data, things like that for clues as to what ELEMENTS are present, but determining exact atmospheric makeup, geology, what sorts of hostile viral lifefforms may be present, how often the planet is smacked by big asteroids or gamma rays, these are not things we can TELL from earth. We don't even know for sure if the human body can TOLERATE the rigors of interstellar travel, we can't guarantee any objects wouldn't be in the WAY of our ship that even with a shield would destroy it. There are MILLIONS of variables we don't KNOW about, so ANY trip there would be a blind one at first.
Realistically, before risking human lives on a 40+ year one-way trip (if it's a generation ship, even worse - maybe you take centuries only to get there and realize you CAN'T survive there - and then there's the ethics of giving birth to someone in space, so that they are born in a can in space and are forced to spend their entire life trapped in that ship) - you NEED to send scouts in advance. SO, we'd need to maybe send some LIGHT SAIL mini probes that can get up to let's say 30% light speed - low mass, tiny things propelled by giant light sails - the tinier the better because it's not a practical technology for a big ship - too heavy - get them there in, let's say, 15 years - the SIGNALS we get back take 4.36 year so about 19.5 years from launch to when we get our first up-close data back. And you'd want to send TONS of the little things, not just one - because you need to maximize the amount and KIND of data we get back so that we're not going to have to wait ANOTHER 19.5 years to send more if we miss anything, they run out f power, get destroyed on the way, malfunction, etc But to even DO this you also need to build basically a giant laser - maybe on the moon - that is aimed at the sail of each one to give them an extra push - very time consuming, expensive, and requires lunar construction bases.
At MINIMUM, even if we started NOW, it'd be 20, 30 years to get the PROBE swarm capable of those speeds, the lasers built, dozens to hundreds of mini-probes launched and built, at a massive cost the public would complain about. THEN we wait almost 20 MORE years for the data back - so 40 to 50 years is the BARE MINIMUM (2074) for when we'd even have an ANSWER as to whether any planet in that system is truly habitable and exactly what we'd need to bring to survive there. THEN, because you DON'T want the colonists arriving with nothing set up to manufacture oxygen, water, etc , you'd want to launch a series of BIGGER missions designed to LAND on that planet with supplies already on-board - they'd start automatically growing plants they have brought with, producing breathable air (because chances are next to zero another planet just HAPPENS to have our exact atmospheric composition WE evolved to breath - 21% oxygen, mostly nitrogen) - and Those would be slower than the much lighter probes, realistically - maybe 10% light speed - so THEY'D take 43 years. ANd you'd HAVE to wait until they were down on the ground and operating for a while because yu do NOT want to send a bunch of people on a one -way trip to and the planet only to realize upon arrival the critical systems they needed crashed or stopped working. You COUD send a really BIG ship - but the bigger and heavier it is the more power you need to accelerate it to 10% light speed (any faster than that with our current science is not likely) - and the technology would be then UNTESTED on that new world. Which is bd. You want to take NO chances with that, so make SURE it works, before you even THINK about sending human beings.
SO, we have 2074 for a minimum time to design, build and launch a swarm f mini-probes, get the data back, if the data is a green-light on human habitability, sending the advance ships (unmanned) with all the machinery and so on they'll need upon arrival, and start that running. You'd want it running at least, say, 10 years without issue before you'd ACTUALLY send manned ships. So 2084, MINIMUM date for sending MANNED ships. It arrives, assuming 10% light speed - in 2127 - a bit over a century from now. We don't know whether they SURVIVED the trip or not until 2131 minimum (takes the message that long to get to us). We send a "received" message - they don't get that fr another 4.36 years, close to 2135. Any messages and updates from THERE would also take over 4 years, 8.7 years round trip. Communication would be VERY slow, so they'd be on their own, knowing if any help COUD be sent, an SOS takes 4.36 years to get to earth and a mission to them takes over 40 years to get there - by which point they'd a be dead.
And that's not even considering the cost an difficulty of building giant moon lasers, light sail probe swarms, the advance ships, and the final MANNED ship, which wouldl be huge and likely take DECADES to build. It's hard and expensive to transport even SMALL things into space - so you'd be looking at a LOT off very expensive launches - meaning a MOON base is likely needed FIRST, one which is permanently staffed AND has its own refineries and mean to make metal ad wiring and everything you'd need. THAT realistically won't happen for many decades at our current pace.
But there you have it. REALISTICALLY, we're looking at an EARLIEST arrival time of nearly 2130. But given our ACTUAL pace of development and the lack of motivation in governments or funding for such a thing, it could be 500 to a thousand YEARS before we ACTUALLY got around to it. I mean, we're just NOW talking about sending people to walk on the moon again - over FIFTY YEARS after the last man walked on the moon. You'd need a concerted multinational effort to do this on a time scale that'd even get us there by 2130 - funding and all - and THAT, I'm afraid, is very, VERY unlikely unless a planet-sized asteroid we can't divert the orbit of in time due to its sheer size were hurting toward the exact spot earth will be at in 2150 or so and we KNOW for SURE that earth WILL be destroyed by it at that time. It'll take an existential crisis like that to FORCE powers that be to MAKE it happen even in the next 100 years. Without that push? Centuries, maybe thousands of years. WHICH, by the way, MAY be a big answer to the Fermi paradox - you don't see aliens flying around the galaxy colonizing worlds simply because the whole thing is too hard and takes too long and civiizations die off before they ever muster the motivation to actually do it, be it by nuclear war or something else.
Yes, unmanned probes would be the only way. With both distance and time a huge factor, and the likelihood of finding nothing even remotely habitable upon arrival, a manned mission would not be feasible. I can't imagine even the most dedicated astronauts and scientists being willing to spend their entire life in an oversized tin can hurdling through space just to reach an uninhabitable rock to take some pictures of and send back right before dying of old age. Until technology improves exponentially no humans are leaving the solar system anytime soon.
for just one communication would take over 8 years for a reply >
What about the huge acceleration forces??? No human can endure that…. Oops forgot to mention that!!! (beginning of the clip)
Let's get to mars first and put a refueling station in orbit first. Space X
Project Orion would also empower some unsavory extremists.
The first is that it will take twenty to thirty thousand years to get to the Alpha Century. First of all, Alpha Century is 4likers away from our world. So go there and dream about it far away, we may be unemployed
Why would we want to colonise someone else's planet?
Maybe in about 7or 8 thousand years. But it is most likely uninhabitable anyway
Muita fixe
You can only if theres a wormhole
Space travel is an incredible waste of money
5:08 "Thrust is nothing more than the force that develops the engine".... WHAT?! Wrong on so many levels...
In the slim possiibility it is habitable,we cant even get there never mind colonise it.
What is the point of this? Can you not tell the difference between reality and fantasy?
Good information. Very interesting stuff. However, there probably is not much in Alpha Centauri worth sending humans to. Proxima B is probably more similar to Mercury than it is to Earth.
Thanks! You're right, Proxima B may not be as Earth-like as we hope.
Yeah I’m all in on using the Orion design to safely deliver probes to the system. The interstellar versions of Voyager if u will.
It’d nice if the ship could make these probes but at the worse, the ship is just the mail truck.
No, we cannot even colonize the moon.Or mars they're a lot closer
Humans will never reach another planet/solarsystem etc.
Stars are moving away from our system...
Appreciate your thoughts. Thanks for watching!
If we would have put some effort into deseighning solar sails we would be there already !
The effort is there. The material and engineering aspect is where we’ve been stuck. Solar sails aren’t new tech.
If we’d put the effort into NPP tho, we would be about 20 years away from a flyby.
It’s not enough for reps to show up. If you rep 6000 workers, those 6000 workers should be there. That’s what solidarity means. It’s not the same as “we wish you good luck as you take in the fascist state.” 💖😘
Colonize is a bad word. What if someone lives there? Not again. Geez. Humans 😮
I love Jewel Verne!
We can't even get ev cars to charge bruh..
This site just uses the same videos whatever it is speaking about they often bar no similarity to what's spoken.
Focus first on Mars...
No, is it is a multiple-star systems, no life multiple gravitational forces and solar radiation problems!
No.
As the world is today, the people wouldn't let any space agency launch nuclear bombs as a payload to space.
80,000 years with the kids in the back seat
Are we there yet ? Are we there yet ? LoL 😂
The problem is alpha centauri is so far
And with todays technology it would only take 30,000 years to get there!!!!! Keep dreaming.
72,000 years …
It's one thing to dream up an idea, and another to build it. It's also one thing to propel a rocket to 10% of c: that's a tremendous accumulation of kinetic energy! Now imagine an object in your path, say only 100,000 km away. You have a little more than 3 seconds to avoid it. If you don't, then it also has a relative speed (relative to you) of something close to 10% of c. Now imagine the kinetic energy turned into heat and destruction during the collision. It's definitely another thing to imagine how to prevent that!
But space is big, you say, and matter is scarce. What could happen in only 40 years? Starvation? Asphyxiation? Radiation poisoning? Or maybe alien intervention? 🤣 Yeah, the last one is unlikely, so I guess the others must be too.
what’s all this old technology from the 50s, let’s show some new ideas pls
Problem is, better designs have already been conceived. Designing and building are two different things. Anything we talk about was already discussed in the 50s but the with the tech at the time, NPP was(and still is) the most feasible.
Plenty of videos about Solar Sails to know that building one that could withstand the thousands of micro-meteor impacts is a doozy lol
4 years we can be there. The Q is How can we see on the surface Sending a holagram from sun heat solar laser moon mirrors particles light energy crystals
we can't even go back to the moon. sit down
All our moon money slow joe spends on immigrants, and equipment we gave to Iraq, plus Ukraine conflict
And when we did go there 50 years ago, we did nothing there.
Sounds more like a nuclear cannon😅
Would there not be a Lagrange Point between Proxima and the other 2 stars to park our ship opposed to trying to directly stop at Proxima b?
Shed speed using the other 2 stars, park on the outskirts of Proxima and then go from there?
Not going 10 percent the speed of light
No!
short answer, no
No science to see here.
Im sure we will get the moon and mars colonized the moon first to learn and then mars
No
What happens if Aloha Centauri is already inhabited?
What happens if Alpha Centauri is already inhabited?
It won't be. Most likely it is an uninhabitable tidally locked rock scorched on the side facing the star from solar flares, and frozen on the side facing away from the star.
The same thing that happened when North and South America was already inhabited.
Generation ships
Who the hell cares if we can build a machine to go to a distance place? The real problem is that humans would never survive a long journey in outer space.
People would have trouble on long trips where there is no where to stop and take a break,even going to mars would be tough
Who watches a video about interstellar travel just to comment who cares 🤔
I ate breakfast this morning. Boring..........!
We cant even easily travel to the moon yet, let alone to another solar system lol if we are lucky, if we dont self destroy in a nuclear war, we maybe, MAYBE will colonise the moon and mars just maybe by the end of the century
Easy answer, no.
None of the videos are relevant to the content of the narration. Simply terrible. What has a UFO got to do with a pusher-plate rocket??
Hahaha they’ll be using DEI hires to get along for a few hundred years. Good luck 😂
the best guess is sending humans to mars in 2069
