I was just thinking, somebody should tell the folks who made "Interstellar" they need to get better science consultants. Wait, what was that? Kip Thorne? Really? The guy who makes Insane Curiosity must be the smartest person in the universe! He's proven wrong every physicist since 1907, when some random no-name dude first theorized time dilation. I see a Nobel Prize in someone's future!" I suppose that according to multiverse theory there exists a reality where/when the science in this video is accurate. So he's got that going for him. Fear not though. I KNOW the second the fine folks at Insane Curiosity realize the error they will either edit the video or add a note in the description explaining how exactly they could have made it through research, writing, producing, editing and publishing without saying "Hmm, something seems off" It's not like they transposed a number somewhere. I mean, they (a science channel) got the entire concept wrong! Then again, if you hear it on KZbin, it must be true!

At present, the closest star and exoplanet to us are impossibly far away. The fastest man made object so far, Parker Solar Probe, which doesn't carry any humans on it, and is using the sun's gravity for acceleration - would take 11,000 years to reach proxima centauri. Even if we could go 100 times faster, that is still over 100 years to get there. Humans don't live long enough to reach other stars in any foreseeable future. And, its interesting to think what sort of alien life form could and would make the journey from where they originate to here, considering the incredible distance. They'd need incredible tech and super long life spans, neither of which we have.

We're talking about a trip of 11,000 years. That's longer than the time between the invention of writing and now. 11,000 years ago we were hunter-gatherers. 11,000 years from now, who knows what society and technology will look like on Earth. Nobody can predict that. Nobody could have predicted our current society 11,000 years ago. One thing is certain: a group of people aboard a spaceship won't change much, societally, in that time, and definitely not the same changes as we who remain on Earth. The people who travel to Proxima Centauri won't even be members of the same civilization that remain here on Earth. Communication will be almost nil, since any exchange of messages will have a roundtrip timelapse of almost nine years. And with the cultural differences that would arise, what would we even talk about?

Reality is we most likely will not attempt sending people to another system until we have established ourselves in our entire home system. Allowing refuel, or repair at a significant chunk of the distance.

I found the book ' A Journey ( or Voyage ) to Alpha Centauri ' at the town library in the late 1960's, it was a well thought out journey of a generation ship.

Look it up and the publishing date i.e. 1960s. It should be traceable unless it wasn't widely published or only published locally.

[@jssomewhere6740]

It does sound interesting. If for no other reason than to compare the details in the thinking from 60 years in the past to the ideas of today. I have been of the opinion that much needs to be established in our own system before we will send people on that kind of journey. I think we need to have a self sustaining space economy before we can put people on a ship to go 4+ LYs away. We need to kind of build our way deeper into space. Create truck stops through the solar system. Habitats that can refuel and can increase or decrease speeds the ships will travel. Repair damages before the last of our Ort cloud is left behind. I could go on but boredom for you would be terrible. Basically build our way out into the galaxy. Everywhere we go is a new addition to the ever growing highway system we slowly build through the galaxy.

If you can travel at the speed of light, it will take you about 4.3 years to arrive, BUT it's not possible to travel in a ship that fast - not even close. It will take you about 100,000 years to arrive traveling as fast as we can in space. Questions?

[@OLDCHEMIST1]

Even if the technology to go at a significant fraction of the speed of light were to be developed, there would still be many problems: 1. No-one knows what parts of the spacecraft might break down, so probably at least two replacement parts of every essential component would be needed, which would be an enormous amount of extra weight. 2. There would have to be plenty of emergency procedures for the possible holing of the ship - any leak would have to be detected and mended very speedily. 3. Even though the craft would have to be almost perfectly hermitically sealed, some loss of materials would take place and so there would have to be extra supplies to cover this. 4. There are numerous possible health problems which could occur due to the journey and all the others which would happen naturally such as cancer. How would these be dealt with? What if the journey were compromised by too many of the crew being ill or dead to guide the ship. 5. What provisions would there be for unrest, say some of the crew want to end the journey and return to Earth? How would any social unrest be dealt with? These are just problems off the top of my head. There will be many problems only experts know of and many which the first human explorers discover for themselves .

There are some errors in the video. The weakness of gravity has a greater influence on the time of the gps satellites then the speed. Their clocks are running 45 microseconds per day faster then the clocks on earth. On the other hand, the speed makes them slow down only 8 microseconds. This also means that a clock on a spaceship flying close to the speed of light will appear slower compared to a clock on the earth, not faster.

I don’t know where Proxima Centauri is really relative to our solar system. I guess what I would be curious to know is if the PC system is-in front, or behind us-so to speak. Like since we know that our solar system orbits the center of the galaxy, would it be “faster” to launch a craft towards a system that is in effect behind us? So then as we moved toward it, it would also be moving toward us? Of course this would make the return trip much longer I assume. Bah! All this is mute. We already use probes for most of out space exploration. I don’t think that humans in space will ever be possible. Eventually we’ll have to creat AI. Advanced enough bodies for them. Technically the AI on ship and the bodies could function as a whole of the same AI. This is honestly the only way I see space explorations as feasible. As humans we have to take our whole environment with us. Food, water, oxygen, gravity being the main ones that come to mind. Without gravity, any baby’s born in zero G- their development would be so unknown. They would obviously have very low bone density and muscle development.

There are a few ideas that scientists and science fiction writers have explored. Some propose cryopreservation, freezing bodies to preserve them until they can be buried or otherwise handled upon arrival. Another idea is creating a designated area on the spacecraft for respectful and secure storage of remains. Alternatively, some suggest the idea of launching remains into space, though this raises ethical and practical concerns.

No way is a space craft designed to take s crew of a size needed to go the distance spoken of,is launched in a single launch. The craft needed would require multiple launches and some assembly in Earth or more likely the Moons orbit. This craft will also require multiple propulsion types. Fueling would also be done in space. Chances are there will be more than one craft to act as a safe guard. The biggest problem is not propulsion it's shielding. Something that could be repaired or replaced during the trip. That doesn't cover even a small percentage of the challenges to make the spoken of trip.

[@tomusmc1993]

I know others have said it, but the time dilation examples are wrong and backwards. The bigger issue I take is that there is no way we are getting to 90% the speed of light, but time dilation is still in play because of the high speed they will be going over the long period of time. Just like the GPS satellite issue. Because of Proxima B being "earth" sized, I highly doubt we (people) would land on it, because you would need a ton of energy to get back off

[@polisagora2811]

Is it possible to travel to the stars ? In a limited way, maybe. Let me be more clear. The nearest star (a binary system) is Alpha C, five light years away but there are at least ten stars within ten light years away. While staying within the laws of physics as we know them it would be at least that long to get there and that much to return. To go to almost light speed you would accelerate at one earth gravity for about a year. You could stand that, then for four to ten years you would coast at near light speed. En route your craft could be like a spinning wheel so centrifugal force would throw you out to the edge and so supply artificial gravity. When you get near then you turn the craft around and decelerate to the destination. So add two years to the trip. Then you spend what time you want exploring then return. What we don’t at present know is if interstellar space has anything solid in it that you might hit. At that speed it would hurt you. Expect Einsteinian time dilation so to you it wont seem so long as it will actually take. We have the Voyager probe out there now and it is fifty years old. Perhaps you want to send a very advanced AI to do the first survey trip. You might leave a string of relays to enable reporting back what you find. Then your near descendants will have contact with the nearest stars. That is all nearly possible. You still need a means of propulsion that needs no fuel. Atomic or maybe fusion energy could do that but then you still need to convert that energy to thrust. We don’t have that yet but we are working on it. That is at least more possible than scifi space warps or ftl drives. Hopefully that is in the future, then the light speed craft can be met when they arrive. I would not count on that. The idea of ftl travel may be the modern philosopher's stone. You think it could exist but its just not possible. Only ten stars ? If you don’t plan to come back, maybe in a sleeper ship, it could be more. If the probes have a way to communicate back, they are AIs, and they don’t decelerate maybe they might reach out more. If they are just probes they would enter a cometary orbit and stay there collecting data. If there is anything interesting out there the probes could let us know. That might be dangerous. Suppose the Easter Islanders had gone exploring and they contacted the Spanish ? The Galaxy could be, as Cxin Liu has said, a "Dark forest".

What about ion propulsion

[@joehntr3]

Because of the size that the ship would have to be it would need to be assembled in space because it would need to be gigantic. Next thing you totally missed it on explaining Time Dilation, the outcome would be opposite of the way you broke it down. Depending on the top speed of the spacecraft somewhere around the middle of the flight or beyond you need to start slowing down. It will not be like coming to a stop at a red light. You will need around the same amount of fuel to slow down as you did to speed up and like I stated you will need to start the slowing process a long time before you arrive.

The closest star system to Earth: The Alpha Centauri system, located about 4.37 light-years from Earth, consists of three stars-Alpha Centauri A, Alpha Centauri B, and Proxima Centauri-and is the closest star system to our solar system.

[@DavidSimons-ss5kn]

Just a few points: It's true that just like with voyager & other spacecraft if you can get it as fast as possible momentum should maintain that speed indefinitely if not interrupted. Nuclear propulsion sounds great but bear in mind the R T generators on the voyagers are only going to last 50 or 60 years & the trip to Alpha centauri group being optimistic will take hundreds or more like thousands of years.When the nuclear fuel is exhausted the ship will need more energy sooner or later if only to manoeuvre & much more. Putting aside that problem for a moment I wonder if nuclear power could generate enough direct heat to simply propel by heat convection alone? Probably not but just a thought - which scientists have no doubt considered.

[@InsaneCuriosity]

Thanks for sharing your thoughts!

[@cher8005]

The whole conversation about travelling to this star system is ridiculous. We will never travel beyond our own solar system and that's just the sad truth. Don't believe me? Check out the stats for yourself.

[@ravantstudios3113]

What you could do is have some kind of solar panel renewable energy system attached to the solar sails to provide energy and light for plants inside the ship to photosynthesise and grow food for the crew members. The crew member give the plants CO2 and water and in return, the plants give you Oxygen and food. Water can be recycled through the ship and the plants so no water is lost and urine can be filtered back into water and faeces can be used to help fertilise the soil for the plants.

[@anthem1982]

2 games introduced in the video, I can recommend it to kids too! the games inspires young generation to intersteller travel and encourage them learning science.

[@GeorgeNoX]

Elite Dangerous has the most scientifically accurate representation of Alpha Centauri system out of any game by far, and in it its stated that Proxima B is uninhabitable, in fact all planets in the system are.

[@jimbutler2784]

How will the starship slow down upon arrival?

[@InsaneCuriosity]

The starship would use its engines to slow down by firing them in the opposite direction of its travel. This process, called "retrograde burn," helps reduce the speed as it approaches its destination.

[@george6252]

Emergency brakes. 😆

[@mm-dw4rr]

With such leaps and bounds in scientific discoveries it all seems only a matter of time. 🙉

[@paulbrookes413]

Light Years Away 😁

[@johntatman8182]

The Robinsons tried to make it there too and they ended up joining through space for a long time trying to find out where they are LOL

[@おすし-f5z]

Having been watched through this video, I learned "how great No Manns sky"is.

[@Joe-ym6bw]

I'm getting on board the next flight I can hardly wait

[@christopherdowling1478]

Imagine going on a mission for 10,000 years to another system and but then 200 years after they launched, we develop faster than light speed…. Would we pick them up? Or just leave them to themselves and have our ancestors greet them when they arrive in 9800 years. 😂

[@Joe-ym6bw]

Let them make the trip and we'll greet them when they get there if they get there

[@jackgoff2072]

You saw him answer that question on one of his older videos.Nice try attempting to be intelligent.

[@Road_Rash]

It would be our decendants, not ancestors...our ancestors are the people who came before us, our decendants are the ones who come after us...

[@sbutler860]

Apparently you can use video games to simulate travel to Proxima B and other planets. Extended advertisements for two games - something about Starship Warlords and No Man's Sky - are almost word-for-word identical, proving that this narration was generated by GPT. But, in No Man's Sky, planets are procedurally generated, meaning that no two journeys to the planet will be the same. What's the point of that? And furthermore, there is no mention of SPACE ENGINE, which surely IS scientific and more accurate, at least to the extent of human knowledge. x

[@ralf1K985]

Unfortuately this video is not up to date. Some time ago, a 3rd planet was discovered in the Proxima Centauri system.

[@Notorious_G.O.D_76]

I would love to explore an alien world such as "Planet Serpo". After reading the book "A Secret Mission To The Planet Serpo" I was fascinated of what Serpo like...... 🌏🌎🌍🌏🌎🌍

[@JanLarson]

There is absolutely no way hat there will ever be an attempt to launch a mission to another star system until such time that warp drives are practical. A 400 generation mission? That's laughable.

[@ericgolightly8450]

How about a giant 1 or 2 generation ark?

[@thastinger345]

We don't need to travel light years IOT find uninhabitable trap houses, we have plenty of those right within our own solar system.

[@richardsmith1284]

My question is why would you even consider colonizing a planet around a dwarf star logic says you be looking for a son exactly like ours so your search should start there

[@davebishop8961]

Just imagine how much food and water you would have to carry in order to keep a crew alive for decades.

[@tomlorenzen4062]

Interstellar space travel is a dream, never going to happen.

[@wildmountainbear9117]

We will never achieve Interstellar Space travel until we take Rocket propulsion out of the equation. Wormholes, Warp, gravity wave. I know Science Fiction, but I can't fathom a 100-year trip to Proxima Centauri. Too many things can & will go terribly wrong.

[@maureenandcolinisles47]

Anyone who believes humans can somehow travel to this star system are absolute dreamers. When are we going to realize that Earth is all we have as we slowly make our planet unlivable resulting in humanity ending up on a treadmill to oblivion.

[@cowlevelcrypto6098]

The space craft / ship/s would have to operate as a closed system, a terrarium . All resources are reused, all resources are valuable, yesterday's coffee is tomorrow's coffee. No ejection of fecal matter, and no "burial at sea".

[@jbx1967]

So think about this: Four hundred generations of people come and go during this trip. We're assuming the people who arrive are going to be interested in and capable of performing the scientific research we're hoping to accomplish. Why would they be interested in sending information back to a civilization they're not even a part of. A civilization that existed so long ago they feel no sense of connection. They might even feel animosity to the people of Earth who doomed them to fates they never would have wanted for themselves.

[@dylanthomas12321]

I just wondered why didn't they go back and fix it. I'm more astonished that they just let the mistake go uncorrected than the fact they made it. The site seems designed for kids or young adults who woul get confused.

[@srinivasrao941]

By the time humans develop vehicles that could travel 10% of light speed, humans could also invent a mechanism where human beings can live up to 500 years, so it might be possible for humans to travel for 40 years.

[@doghousedon1]

Why do they put wings on a spaceship?

[@danielsee1]

The Moon is a spaceship, it brought life here FROM Alpha Centauri.

[@donaldmackerer9032]

What about ion drive engines? They were successfully used to visit an asteroid not too long ago. The trick was to use a propulsion type engine for the initial thrust and get it to a certain speed then switch to ion drive which starts out slow but increases speed as it goes along. Plus it gathers ions from the space around it and doesn't need refueling. I would imagine we would send artificial intelligence long before we would send human space Travelers there. If the artificial intelligence found anything that was of Interest and worthwhile then we might send humans later on. I think Alpha Centauri B and C could be more promising because their stars are like our sun. I really don't understand NASA's current obsession with red Dwarfs.

[@MegaGronis]

A trip to Alfa Centauri will take at least 50000 years at the speed of the Voyagers. A very very long time.

[@factsrus3462]

Just a blip in the grand scheme of things those numbers may just be what it takes to get to other stars maybe we can shorten it some but space it’s big we just need patience for this part of our species expansion

[@bebotmaat1557]

People from that planet PROXIME CENTAURI B have already reached our planet Earth way bk 1961 to 1962.

[@Perspectives_with_Adebuea]

We need a launch window n trajectory ? I mean I’m sure by then we will come up with some type of gps 😂😂

[@ericgolightly8450]

It takes light years to get in between the stars. Idk what GPS would do to help though.

[@sudipdutta72]

is it necessary that a planet closer to its sun will be tidally locked?

[@robvangessel3766]

The Jupiter 2 had the technology to reach Alpha Centauri in about 5 years. And that was in 1997.

[@Wraith-Knight]

LIGHT YEARS is a striate line if you did that to get there you would of missed the system by the time you got there

[@Wraith-Knight]

YOUR ALREADY LOOKING AT WHERE IT WAS 4 YERS AGO BEFORE YOU START THE TRIP

[@wolfthorn1]

Journey To Alpha Centauri..... Are we there yet? Are we there yet? Are we there yet? NO!!! We have 70'000 more years to get there. So Quiet down or I will turn this spaceship around.

[@mspicer3262]

You got time dilation wrong. If you were on a spaceship traveling at 90% of light-speed, you would experience 5 years pass before you arrive. An observer on Earth would experience nearly 11.5 years pass. A round trip would have the light-speed traveler experience 10 years, and the human on Earth, 23 years. It's the Lorentz factor formula if you want to look it up. Omni-calculator even has a calculator to do the heavy lifting for you. All you have to know is how long you are traveling, and your speed in km/s, 90% of light-speed is about 269,800 km/s. You would need 5 years to travel 4.5LY at 90% of light-speed.

[@Dancerlayla-z6g]

Solar sail? How do you stop at alpha centauri ( where the trisolarans live lol)

[@handsupbud]

My gut feeling is when we get there we'll find conditions aren't condusive to us living there. I think it's a wasted trip.

[@qpr543]

So we should be prepared for return trip?😅

[@jbx1967]

11,000 years of nul-G. Hah. I don't think so. Blobs of jelly would be the landing crew.

[@Big.Bad.Wolfie]
