Of course interstellar travel is possible. It surely will not look like you think it will though. You can forget about powering from point A to point B. And time is insignificant.
If we remain in only our natal solar system we are doomed to die.
An intelligent race would not accept that I believe. Then if my presumption is correct they like ourselves will go outward even if we must crawl across the galaxy.
Ya, we are not leaving the solar system. We better take care of the planet we have and plan for the lonnnnnnnnnggggggg hall here. Self-annihalation is more probable than star travel.
We would need robots to make repairs outside the spacecraft at relativistic speeds. Spacewalks are off limits. I'm thinking about a dramatic movie about the last robot sacrificing its "liife" for the crew. Could be a tearjerker.
To go to Proxima Centauri, we need a combo generation -hybernation ship with expandable options. I don't see humanity getting warp drive before 2159 AD!
Also take into account we know very little about the universe we will think of something I’m sure.
We have to come up with some kind of deflector shield that will clear dust and asteroids in front of us. We need some kind of force field technology. This is all science fiction today yes but the science fiction of the past is science fact today. We need new physics. We need to pump large amounts of money into basic research.
None of this matters because it is impossible to have enough food & water to make it.. I think the best we can ever do is maybe europa.
what is his accent?
Because we are but a grain of sand of just the Milky Way..we can only really observe relatively nearby stars to look for life.. We should Terra form Mars and give it a bigger ocean.. There's lots of water available in our solar system.. We need more time...
How would warp drive change chance of impacts? Would particles be deflected?
No.. it is impossible.. nothing this rock we live on has what it takes to build what it takes to make it.
Whether it is possible or impossible, it means nothing to us. It will not be possible in our lifetime, nor the next generation's lifetime. Thus, it is meaningless. Even if it was possible, where is anybody going to go? Are humans going to cross the galaxy to a dead planet?
If you want humans on other planets, maybe send robots to places that have the raw materials to make humans, and then assemble them there, bypassing interstellar radiation, but requiring better medical care, more precise engineering, and understanding of our currently functioning planet.
Remote science to put it mildly. 100s or probably 1000s of years in the future if we survive that long. Sending non-biological machines is more likely, but we would have to wait hundreds of years to know what they discover.
We are so stubborn, why can’t we view space travel the same as moving in water? We have to find a way to coat from the resistance same as fish do to glide through water.
Is it not true that when approaching C, you grow infinitely massive only in the direction of travel?
The fundamental problem is that we are not looking for just any old star; we are looking for an inhabitable planet suitable for human civilization.
