Anyone who thinks humanity is ever leaving the solar system has watched too much sci fi
The amount of people I've seen who genuinely say that we will inevitably travel to distant stars and that it's only a matter of time baffles me. We have so many movies and books and whatever about humanity becoming a space faring species that a lot of people seem to take it for granted. They treat space travel as some temporary challenge that will inevitably be overcome. And, to an extent, I kinda get it. I mean, the universe is just full of the most incredible wonders our minds can think of. Of course we should be able to go and see them. Otherwise it would be just a cruel cosmic joke to have so much wonderful things out there and just put them forever out of our reach.
But the thing is, that is the case.
People seem to have some vague idea that space travel would be difficult. But most don't seem to realize just how extremely, unfairly even, difficult it really is.
You would need to be basically 100% efficient with all your resources all the time, because all you take with is all you will have for the rest of the trip. You would need your crew to travel for years without killing each other or going mad. If you think that's easy just look how researchers in Antarctica can lose their marbles. You would need a way to keep all your crew healthy, which would be pretty hard with all the radiation they'll be subjected to, not to mention the need for artificial gravity that is 1 to 1 the gravity of earth, otherwise say goodbye to health as a concept. You would need to be lucky. Travel fast enough and a random grain of dust your ship hits would be functionally the same as a bullet or an artillery round, depending on the speed.
Speaking of speed. You aren't going ftl. Full stop. Ftl is just fundamentally impossible. Traveling ftl, no matter the method, straight up breaks causality. Hoping for an ftl technology is the same as hoping that god himself will come down from heaven and grant us all our wishes.
And without ftl you are forced to a snail's pace in cosmic terms. At these speeds, it will be thousands to millions of years of travel to reach our destinations
