As of right now, it would take about 80,000 years to reach Proxima Centauri, the closest star to our solar system. In the future, do you think we will come up with some sort of way to travel these vast distances and enter other star systems, or are we trapped in our own system for ever?

I understand where all the pessimism comes from. We’re a fear devouring civilization right now. But if we look a what we have achieved in the last 100 years, I beg to differ. Through all the world wars and major battles we’ve still managed to progress. I think we’ll continue to learn and evolve. Solving many problems that seem to be show stoppers today. Will it happen in my lifetime? Nope. But everyday in small labs and countless universities there are breakthroughs and progress. Regardless if one country is beating the hell out of another. And it won’t stop. There will be setbacks and hurdles to cross and yet we seem to find a way. It won’t happen over night. Baby steps, and eventually we’ll be able to develop platforms and propulsion systems that don’t rely on the limiting factors those in use today suffer from. It might be completely bogus but for me the Kardashev theory resonates. Pie in the sky? Maybe. Look what they said to Orville and Wilbur. Not that long ago. Cheer up lads and lasses, the end is not here. But just the beginning. Just my humble opinion.

The world will look vastly different then, and maybe we will have figured out a way to dispatch androids on voyages that will last thousands of years, but I don't think generation ships will ever be considered a safe or useful idea. After all, any human-comandeered ship that is sent out an any point in time, will be overtaken by the next human-comandeered ship that is sent out, making the first one absolutely useless (due to advancements in travel speed). That said, I wonder if things like warp drives or wormholes are even physically possible, that would drastically change the way we think about space travel.

Yes. Humanity has only been traveling to space for less than a century. And 80,000 years or so to Proxma is only if you rely on chemical rockets, but even just fission based propulsion can cut it down to under 10,000 years. And that's on the pessimistic side of things, it's quite possible we could reach other stars in under a millennia, or close to a century, with nuclear technology fairly close to what we have today.
The big thing holding us back is infrastructure and manufacturing in space that has the capacity to construct the likes of an interstellar vessel. For that to be possible, we need low cost, frequent transportation to orbit. And we're steadily moving towards that already. This century is likely going to be a transition period from spaceflight as a highly specialized and risky field, to a widespread place of work, still specialized and risky, but not as much as today.
But bottom line, I don't believe we'll be limited in the solar system, or on Earth. In any case, there's a lot we can do here. And it'll be quite some time before we exhaust everything, by which point, interstellar travel may be as difficult as putting together an interplanetary mission now.

Yes, but there's a few prerequisite technologies that we need to figure out before it will happen.
The key tech in my mind is:
- Fusion energy
- Near complete mastery of bioengineering
- Major space manufacturing
Need fusion energy for propulsion and powering the habitat.
Bioengineering is a catch all here for mastery of genetics and gene editing, artificial wombs, construction of artificial ecosystems, organism engineering, suspending animation, etc. We'll need to engineer ourselves and the things we wan't to eat to do well in low gravity and high radiation among other things. Extending lifespan into the 200+ year range and/or making suspending animation possible will help with motivating people to make the journey. Probably need artificial wombs as I can see pregnancy and birth on a spaceship being an issue.
Need to be able to build a big ship AND fix it along the way. If you're gonna have a self sustaining population of humans on this thing thats a huge ship with tons of redundancy needed for every system. You can't realistically build that by launching a bunch of little things into space on separate rockets, probably need asteroid mining and automated in-orbit construction around Earth or the moon. You also need to bring this capability with you if you want to do anything meaningful at your destination.
Basically once we're at a point where a lot of people already live in big o'neill cylinders around Earth some group of adventurous/crazy people will stick a few fusion rocket engines on one and head for the stars. It'll be good that they're already in a self-sustaining space habitat because the planet they go to is likely to suck, and they're gonna spend another 1000+ years in orbit seeing if von neumann probe-type robots and engineered microbes can get the planet somewhat livable.
Probably 100+ years before any human interstellar journey can even be considered.

Is 1 billion or 1000 million years enough ? To give your some perspective, after homo sapiens evolved, humans didn't discover fire for 2 million years. After fire, in 200k years we move to 0 year (current start of AD or BC years). Out of past 2000, just 500 yrs ago Galileo discovered that earth revolves around sun.

I think it is highly dependent on how technological advances occur. 150 years ago, heavier than air travel was believed to be impossible. 200 years ago, it was believed rail travel would throw people’s organs out of their body. 700 years ago large parts of the world didn’t believe there was anything beyond Europe, Africa, and Asia.
The biggest hurdles will be energy, time, and willpower. We will likely need to have technologies like miniaturized fusion reactors, better radiation and impact shielding, and either better fuel sources or faster propulsion systems.
I think it is possible we will eventually travel outside the solar system. But I also think it will not occur within the next few hundred years, and will likely initially occur via miniaturized space probes with no humans for a decent period after that.

Siellus t1_iw4ut4h wrote
Proxima Centauri is 4.2 light years away - There's no possible way your math checks out. You would need to be travelling at Light speed the entire length of the trip to get there within 4 years, You're also completely neglecting time required to slow down, which would be significant.

hardervalue t1_iw59vy5 wrote
1G of thrust is impossible to maintain for long without millions of times more energy than humans have ever generated during the entirety of human history. The most dense amount of energy possible is antimatter, which we've only created nano-grams of at a cost that would extrapolate to $67 trillion per gram.
And if the math on this page is correct,
https://www.desy.de/user/projects/Physics/Relativity/SR/rocket.html
for every ton of ship & payload you want to send to Proxima Centauri you need 10 tons of antimatter to get there and 37 tons to actually slow down to visit instead of flying right by. The reason for the difference is the tyranny of the rocket equation, which means every ton of fuel you add to try to go faster increases the amount of fuel you need to get to the same speed because you also have to accelerate that additional fuel And that assumes 100% perfect engine efficiency, which is unlikely.
In reality solar sails driven by huge lasers is going to be an important part of travel to nearby stars because it avoids the tyranny of the rocket equation.

themonkeymoo t1_iw4vkx8 wrote
That mostly depends on whether or not matter with negative mass can exist in this universe. If it can, then the Alcubierre drive is possible (once the insane power requirements are resolved). If not, then he best that we know is definitely possible is around 0.1C. That gives us a transit time of 10 years per light-year, or around 40 years to the Centauri system. That's with Project Orion (a rocket-like vessel powered by literal fusion explosions).
So unless we can significantly increase the fraction of C it would probably be literally a once-in-a-lifetime thing, if that, for most people.
There are some theoretical possibilities, like replacing the fusion explosions with antimatter explosions (or even some sort of actual antimatter rocket) or the Alcubierre drive. Both of them require currently-unattainable quantities of special materials.
Any sort of antimatter-powered vessel capable of carrying people is going to have a mass measured in thousands of kg (probably many of them) and will require facilities for either storage or in-situ production of similar mass of antimatter for a given trip. Somewhere around 0.2C is where the payload:fuel mass ratio hits 1:1 (assuming in-situ production isn't an option, and of course making assumptions about the maximum efficiency of the engine).
We can currently only make antimatter as individual subatomic particles in particle accelerators, and our current facilities aren't designed for that. With current tech, a facility optimized for it could supposedly make about 20 grams/year. That means 1 tonne (1000 kg) would be 50,000 facility-years of antimatter production with today's technology. I think it is highly likely that this will change in the future and we will actually be able to produce enough to use as an exotic power source for special applications. I suspect that the energy cost to produce it will always remain prohibitive compared to other manufactured fuels, but I'm also sure that at some point our energy production capacity will (eventually) trivialize that by brute force.
As for the Alcubierre drive (which would theoretically allow travel faster than C), it's dependent on a hypothetical type of exotic matter that has negative mass. It isn't used as a fuel, but to generate the negative gravity well on one side of the "warp" field. We literally don't know if such matter can even exist in this universe. It's mathematically predicted by some symmetries, but that doesn't necessarily mean it actually exists. That could simply mean that something else is missing from our models. At any rate, even with the Alcubierre drive generating the field, there still needs to be some kind of energy source to empower the drive, and it takes a lot of power. We're talking planetary masses' worth of fuel even for hypothetical antimatter reactors (and I mean gas giants).

It will happen, a big question is whether the first crews go willingly since it will certainly take many decades if not centuries.
The most likely vehicle is a solar sail like project starshot is based on. It would have to be enormous in size, very efficient, and we'd have to create ginormous lasers to accelerate it. And it would have to spend most of the voyage slowing in order to actually make orbit. For Alpha Centauri, which is a three star system it may need to fly very close to Centauri C (the closest star) and blow past it to do the same to the other two to slow down make orbit around one of them.
