The First Interstellar Journey!
What will the first Proxima Centauri voyage, the closest star to the solar system, be like? Will it be with a spaceship like the ones we have today or with technology that doesn't exist yet? Who will be the crew members of that mission, and what challenges will be presented during the flight?
Let's find out!
When discussing interstellar travel, we must consider a significant factor: in the 21st century, we still do not have technology capable of traveling through the stars.
The spacecraft that have gone the furthest in history are Voyagers, which have not yet made it entirely out of the solar system and still have thousands of years to go to get out.
In addition to the fact that our spacecraft cannot yet travel long distances quickly, we also do not have efficient propulsion systems.
Parker Probe
The Parker Probe is a spacecraft that NASA launched in August 2018 to study the Sun and its corona. It is the fastest spacecraft ever built by humans and has managed to break several records in its short lifetime.
1. Travel with a return ticket
In the first case, we have the most optimistic option of all, a round trip at superluminal speeds, where we can build a spaceship that reaches up to 10% or even, in the best of cases, 20%. of the speed of light, with this speed the trip to the Proxima Centauri star would take approximately 20 years, it is a long time, yes. Still, it is much more reasonable than a trip that lasts thousands of years.
2. Travel without a return ticket
If it becomes impossible to reach such high speeds, even with the advancement of technology in the next few years, the only option left for us would be a mission that lasts several centuries or millennia.
Difficulties and problems
A journey to the Proxima Centauri star is not easy, and many challenges and problems must be solved. Some of the biggest challenges include the following:
Distance: The closest star to Earth, Proxima Centauri, is about 4.24 light-years away. At the speed of light, this journey would take more than four years, which is currently impossible. The journey would take at least 20 years, even with laser sail propulsion technology.

forget the name, but there's an old sci book with that as its premise.

[@vincentbaltus8830]

At 20% the speed of light the time dilation is minimal, so when the astronauts will be back from Proxima, they will be 40 years older and their families on Earth too.

Hmm 🤔🤔. That's a good point. They probably would be resentful & maybe jealous too, of the facts they didn't volunteer or sign up for the trip / journey(s) and that they wouldn't have any memories about Earth, especially after the first generation would live & die on the ship(s).

[@Banane1321]

I would like to kindly point out a slight misconception presented in your recent video regarding time dilation experienced by a spacecraft traveling to Proxima Centauri and back at 20% the speed of light. You suggested that the 40-year duration of this journey is experienced onboard the spacecraft while thousands of years pass on Earth due to time dilation. This, however, is not quite in line with the theoretical predictions made by Einstein's Special Theory of Relativity. In actuality, the scenario works in the opposite way. The 40 years would be the time elapsed as observed from Earth, also known as the "proper time." Meanwhile, onboard the spacecraft, due to the effects of time dilation, less time would elapse. This is because the time experienced by an observer in motion (in this case, the spacecraft) is always longer than the proper time, according to the formula of time dilation: Δt = γΔt₀, where Δt₀ is the proper time, Δt is the dilated time, and γ is the Lorentz factor. In the case of the journey to Proxima Centauri and back at 20% the speed of light, the Lorentz factor γ is approximately 1.021, which means that time on the spaceship would be slightly less dilated than the time on Earth, not dramatically more. I hope this clarification contributes positively to the scientific accuracy of your content. I'm looking forward to your future videos and further discussions on such intriguing topics.

[@joemasters2270]

Glad someone finally said it. I’ve noticed countless videos that ignore the Lorentz factor for the passengers

[@Banane1321]

@@joemasters2270 Your passion for the Lorentz factor is noted, Joe Masters. But the issue here isn't about ignoring it for passengers; it's about misunderstanding time dilation. A nuance, yet a vital one in the realm of relativity!

[@VolcyThoughts]

So according to that factor, how much actual time would pass on earth?

[@Banane1321]

@@VolcyThoughts While the spaceship's clock ticks slower due to time dilation (thanks to the Lorentz factor), the Earth has no such pause. So, while the spaceship's occupants might age a smidge less, back on Earth exactly 40 years have passed. No Lorentz-induced time warp for Earth, I'm afraid!

[@VolcyThoughts]

@@Banane1321 so they actually would return 40 years later but would they actually be 40 years older or only slightly older than when they left?

[@IcarianX]

Honestly, travelling to Proxima Centauri sounds terrible. The absolute best case scenario is spending 20 years in space and never seeing your friends, family, dogs, cats, trees, rivers, the sky or oceans again. The worst case scenario is multiple generations spending thousands of years in space only to arrive on dead, uninhabitable planets. And no, we won't be able to take terraforming equipment there. We can't even terraform Mars, no way we can send the necessary resources to Proxima Centauri. Do the planets there even have magnetic fields? If they don't then terraforming won't work, their atmospheres will be blown away.

[@wolfpaws8985]

find a system with a yellow star instead of 1 that is already on it's way to death .

[@johngeier8692]

The m type red stars will shine for trillions of years. They are most unlikely to have any Earth like planets due to tidal locking and stripping of the atmosphere by stellar wind and flares. A Close Earth Analog Planet similar to earth 400 million years ago would be the ideal destination for the first manned interstellar mission.

[@mk40846]

Best case is it takes you a few seconds to get there and back (travelling at *very* close to the speed of light), while on Earth a total of 8 years has passed. Practical best case at 1G acceleration / deceleration is 10 years for the astronaut, about 16 years on earth for the round trip.

[@foxdavani4091]

I would be an astronaut in a heartbeat. I am forever alone, doomed to never have family, so why not travel to the stars. And if I return, I get to see a whole New World beyond what I left behind, and since I would have nobody to be emotionally connected to, I wouldn’t care that my generations cease to exist. That is the beauty of being alone.

Depends how far

[@fubaralakbar6800]

Interstellar travel methods: 1: Generation ship. A Space Shuttle the size of a city. Your kids' distant decedents will get there, but you won't. Hey, raising kids is all about sacrifice. 2: Sleeper ship. You will get there, and you can even take your kids with you. But don't bother coming back. Everyone you knew will be multi-thousand year coffin dust. 3. Relativistic ship. You will get there in just a few weeks. Okay, it's actually hundreds of years, but it will only feel like a few weeks. Same problem as number 2, you just won't know it's a problem until you get back. Surprise! 4. Orion drive: sit on some nuclear weapons and detonate them. If you are okay with the safety concerns, see option 3. 5. Warp drive. The ultimate. You get there, your kids get there, you and your kids can come back any time they want, and everyone will still be alive. Okay, not YOU and YOUR kids, but maybe someone else and their kids, thousands of years from now when and if the thing gets invented. See options 1 thru 3. Einstein says this one is a no-no, but he also said it might be okay. Besides, he's dead. 6. Worm hole. Stationary warp drive. Think Stargate. See option 5--but remember, you have to be the size of a cosmic string to fit through it. Even Kate Moss can't lose that much weight.

[@ivobrick7401]

subluminal warp drive won't help you much. 7. Frame shift drive. You move through hyperspace with little to no effort. Dont forget to bring a power to speed up to significiant % of the speed of light, and knowledge how to break in and out, even if, hyperspace/multiverse exist.

[@fubaralakbar6800]

@@ivobrick7401 That's basically option 5. Requires bending of space and time. Scientifically, all you have to do is be God (or snort some Spice). Realistically, I think #3 is the way to go. It's probably the best our tech will ever be able to do. And really, it's not that bad. I mean, I exaggerated a bit there--it would take well within a human lifetime, depending on how far you want to go. Four years to Alpha Centauri? With current drives, it takes 3 years to get to Jupiter. New Horizons took 9 years to get to Pluto! Fuck Alpha Centauri, a relativistic ship could make it to Sirius in that time! You could even come back--although a lot would have changed, everyone would still be alive. Okay, so you're not going to have an interstellar empire like that. Communication would take way too long. But you could have a lot of small empires, each occupying a solar system. It would be an excellent way for humanity to spread out and avoid being genocided by rocks, nukes, natural disasters etc.

[@ivobrick7401]

@@fubaralakbar6800 I think way to go is much more simpler. You send slow cargoship to a given system, lets say at 20% speed of light. Loaded with communications, robots, computers and empty shells.

Even if you make it to the planet in Proxima Centauri's Goldilocks' zone there would be a host of problems to deal with.

There will not be any such mission. We will never attempt interstellar travel unless we come up with some kind of FTL propulsion system. And while that is at least a remote possibility, at least theoretically, I don't see any way it could ever actually happen. Humans will destroy themselves long before they come up with anything like that.

[@stevecribbs9247]

This video ignores several factors. It's not just a spaceship which needs to survive the forces involved, but the crew too. They can't be subjected to excessive g forces, and how long would they have to endure high g forces? Acceleration is one thing but you'd also face the same challenge slowing down. A generational ship would require a sizeable population to avoid inbreeding and consequential genetic issues. A sterile environment could eliminate viral and some bacterial illnesses, but at the expense of a diminishing immunity system. Repairs would requirea spare parts and materials stock. We must consider natural degradation of materials when we think of journeys lasting generations. Apart from accumulated damage due to cosmic rays, there will be some humidity due to people's breath and perspiration. This could in time affect components. What if people arrived at the nearest star system and found a world too extreme to survive? Could they even land? Terraforming if even possible, could take longer than the journey there, even if it were possible to get the necessary items in place. Then, you'd need to create a viable ecosystem. Finally, there's a more mundane obstacle which could stop it from ever starting. That is the lack of payback for any government or organisation. There's no profit involved and people and equipment would depart, probably never to be seen again by anyone on Earth. Reports back would be at best monotonous and non eventful provided everything works OK. Eventually, the time taken for radio waves to reach us would cause such a delay as to make effective communication unachievable.

The long journey of 100`s of years or multiple generations would be a total waste of time and money.

Interstellar "practical" human travel is not only beyond our current technology, but it is beyond our current best understanding of nature (General Relativity an QM), as much as human travel to the Moon was beyond the technologies and understanding of nature in ancient Greece.

("practical" means that the enormous efforts and resources invested in making the travel have a "return" (benefits) that justifies those gargantuan efforts and expended resources).

And, the author speculates about significant time dilation at 10-20% of the speed of light. This is wrong. Time dilation is exponential and doesn't become a significant factor until you are travelling in excess of 90% of the speed of light.

[@Nostradamus_Order33]

I have a novel idea. Let’s start with the moon. 😮

[@Karcarius]

They believe they can warp space.When they do that,if they can, it'll take about 2 weeks to get there.

[@Vexterian]

The only way possible to travel to centauri is if there is a safe faster than light transport. Otherwise it is impossible.

[@mk40846]

No, it really isn't. At a constant 1G acceleration and deceleration (meaning very comfortable for those on board) it would take only 5 years ship time.

[@billneal8995]

I would go in a second!

[@peterinburnaby]

A life like Robot would be a better idea with a full time communication link 👽

[@phildavenport4150]

There is absolutely no point in setting out on a journey of this type using only the current forms of propulsion. Until we achieve a folding of space or harnessed wormhole type of travel, all we are doing is condemning a large number of people to a pointless existence in space, only for them to discover that they have been well beaten by a ship having the sort of propulsion referred to. Even if cryosleep were perfected, it achieves nothing.

[@triaenmarsh107]

Hear me out. What about a wormhole engine? Like in Halo.

[@gigakrait5648]

What about warp speed? Warp 10 or even warp 11 because 11 is better than 10. Or how about jumping to hyperspace? How about asking aliens for help? Maybe a transwarp conduit designed by the Borg? Voyager from Star Trek was able to create a slipstream so that it could travel way faster too. Excelsior had transwarp drive also.

[@st.3433]

imagine doing that trip just to travel to a hell and leave paradise our earth. It sounds like worse than death

[@gregmanahan1312]

We need faster than light travel (FTL) to make anything possible to study in a lifetime

[@CesarLopez-nd8le]

I believe it will happen but with current technology it is not possible we need to harness other forms of propulsion maybe using the heat of the sun

[@jeffwinters8152]

intresting would it be posable to go up to the speed on light maybe but not in the way you would think a gravity drive would work better pulling insted of pushing use a gravity amplification to pull the item or ship so if i were on earth had a gravity amplification device aimed it at the moon and set it to two gs it would pull me to the moon you can do the same thing but at a much greater range could you use this to get to the speed on light maybe time slows down the faster you go so if you ever did reach the speed of light for the people on the ship traveling to the star it would take .000000186 seconds for every light year travel for the people on the ship at the speed of light for ever one seconds on the ship traveling at light speed would travel 186,000 light years for every second at the speed of ligh and a 186,000 years would of past on earth for the people on the space ship only one second of time would of passed

[@philipbenjamin1371]

I am in volunteer count me in

[@BurtReynolds.]

I've always wondered if we do get speed to go fast. How do we slow down?

[@wolfpaws8985]

Depends the ship may need to turn 180 and fire the engines to slow down,unless technology advances enough that thrusters will be capable of slowing the ship.

[@sprinter768]

They would have to travel the second half of the trip slowing down which means that they would still take a hugely long time to get there as they would only travel at the top speed for a short period of time. They will probably also have to do some gravitational assists to slow down once they arrive at the destination star system and will need some precise calculations of the orbits of those planets. A few orbits here and there and they will slow down to a speed that would allow them a "safe" landing in the planet of their choosing.

[@shane1489]

Space brakes seem easier than light speed

[@skygge1006]

@@sprinter768 because the first half fired off a lot of weight you can spend more time accelerating then decelerating cause you have less stuff to decelerate so you don’t need as much energy to decelerate.

[@gpierre90]

I will never volunteer for such a mission, in my opinion currently with current technologies we have now, it is impossible to ever make such a mission, in order to make a round trip you need to go like infinitesimal speeds or perhaps if something like "warp drives" or "slipstream" like in Andromeda series or star wars movies or whatever is a thing and you could address the human problems that comes with it not to mention dangers of space exploration then OK, I think mankind may need to evolve for another several millenia before we can ever do it. That is if humans would be around for that long. Sometimes I just wonder why we don't simply explore the oceans on our planet, I think that is more do Able than an exploration to Proxima Centuri.

[@Lexi2019AURORA]

We will never go to Proxima Centauri.

[@happyandhealthy888]

Or we can drive with a bicycle 🚲 from planet to planet. Turning on the lights on the way. 😅

[@ultrasurfs]

miles? can you use km/hour next time? most of us are international audience.

[@nighthawk4028]

We are all on a spaceship called Earth.😊

[@sk111zz]

If the USA alone just swapped its NASA budget with its Military budget think of the possibilities!!!

[@niezdecytowana.k.a.2conten835]

4 months = 40 027 views. *"Esqualited Quickly"*

[@qw3rtypd4ng3r]

And when we get there all we see is a boring star with uninhabitable planets. I’m all for space travel but the technology to do so at a reasonable speed will not be available for thousands of years, if ever.

[@eoachan9304]

Good effort, poor research. With libraries AND the internet you have NO excuse for such simple errors! (e.g, vincent baltus's note). Pulsed nuclear propulsion would be easily in our grasp after perhaps a decade of intense research, and used correctly could gradually boost the speed of the ship a lot faster than 20% SOL, perhaps to 60% SOL. There is of course also the Alcubierre drive too :) Most likely a tech none of us have heard of will be the "it" tech for interstellar travel ;)

[@phoqueanonyme4072]

Is this one of those bot chanels that science guy was talking about ?

[@InsaneCuriosity]

Nope, we are not fans of those channels too

[@eternisedDragon7]

What it will be like? It will not be like; it will not exist, that's what it will be like.

[@richardofutuasella3453]

Let's say eventually human reaches proxima centaury and manages to habitate in proxima centaury B. Won't the same thing will happen there as earth will be eaten by sun here? I am not saying it is useless to reach another habitable exoplanet but what next?

[@kumars1961]

You cannot make predictions about the future based on the knowledge and technology available today. Just two hundred years ago the same pessimistic views would have been said about air travel and setting foot.on the moon. When we consider the tremendous progress science and technology have achieved during the past one hundred years, we can say with absolute certainty that Nothing is Impossible. If a very short period of one hundred years can bring forth such progress, just imagine what it would be like in the year 5000 AD. I am absolutely certain that mankind would have gone beyond the Alpha Centauri system by then.

[@4yerears]

Yes... the same way that it is difficult to grasp the staggering distances between our sun and the nearest ones, people cannot picture where science will be in the distant future

[@alphasoldier2404]

If all nations come together and build one giant ship we can get there easy

[@davidwalker5054]

What will the first flight to proxa be like. Short answer very very long about 70 thousand years give or take a day

[@bjt81366]

With time dilation. So it's possible they could spend twenty years traveling to Proxima Centauri, get there and there could be a ton of humans already living there for a couple hundred years. Because humans a thousand years after they left figured out the wormhole.

[@davehoward22]

Odds are there will be nothing habitable there.

[@tonygu2958]

What would suck is the possibility the planet is at a stage of lava flows and cannot land the craft. Just a waste of time to get there. Should send non-manned ship to investigate the system first. We can be wrong about the system.😢😢

[@budwhite9591]

“Spacecraft we have today”. Shows picture of shuttle 🙄

[@miketaylor7023]

Even in space we need precision gravity and we need to be able to do things like running at full speed! We are alien creatures. And much like all other alien creatures our behavioral characteristics are part of what we are. We don't just escape our past because we believe we're special somehow. Every creature is infinite and unique! And we share similarities seen through fractal analysis. Math symmetries. You absolutely have to push your thinking to the limit. And BEYOND. No limits as Bruce Lee said. It is true to a point. After 30 years of age or other various conditions everyone has limits though. But in developmental reasoning and imagination it becomes possible to engineer mysteries by examining everything around ourselves and even within ourselves. Question your accuracy along with others. Question all the facts. Even those you don't know about. Question reasoning itself! Others including your own!!!! It can be good to ask if one's own thinking is way off the mark! When something is happening it's good to ask yourself the question: What is going on? Study the behaviors of other creatures in yourself! And the behaviors of yourself manifesting in other creatures. In other species too! THINK!

[@russellroadmasterseries2208]

In life u got to take a chance. Be it for humanity as a last resort. To save humanity an find new life far an beyond. Yes we will lose the ones we love as we would be back but who we new would be dead an gone. Is it worth taking a risk. Or just stay back an let life takes us on earth before we depart from earth itself

[@melvino8926]

Wow.....imagine

[@adrian_ad]

If time dilation is really that significant then there’s no point in space travel.

[@jamesms4]

Time dilation only kicks in(that is you notice it) when you go above 50% the speed of light and thousands of years would only go past if you traveled thousands of light years and near light speed like at 99%c or 99.5%c. At 99% for every 100 years the Earth bound observer experiences 14 years. At 99.5% every 100 years Earth time only equals 4 years ship time.
