    The problem with space travel, if we can ever approach or even exceed the speed of light, is that it will only be of use for the people on the ship. Let's say we have a craft that can travel to the nearest star Alpha Centauri, 4.3 light years from Earth. They can do the speed of light, so they go there and back, an 8.6 year journey. Problem is, when they get back home tens of thousands of years will have passed on Earth. We can thank Einstein and his Relativity for that bit of bad news.

    It's not nearly that bad. If we could survive the acceleration, that alpha centauri trip would take merely 8.6 years on earth, and mere minutes for the travellers. But the limits of human physiology won't allow long term exposure to much more than 1g acceleration. Even if we come up with unlimited energy for propulsion, we're talking about decades passing here on earth. Which makes it a trip that few socially healthy people would want to take.

    Apparently radiation is something of a problem out there.

    Mr. Lumbergh needs you to go ahead and come in on Sunday, too.

    I think it's easy to gauge the level of actual interest in overcoming those odds and see that the wherewithal to do so is lacking by far too many. Observe objectively!

    It isn't Einstein's fault that physics behaves the way it does, he was just one of the first to suss it out.

    It will take me about 25 seconds to get to bed. If I travelled at the speed of light I will have overshot my target by a mere 4,650,000 miles. I am really glad we don't travel that fast.

    The reason they made space so big was to stop us getting out.

    Interstellar travel would be a bonus to humanity. We might find fifty earth like planets to live on in case this one burns up or gets hit by a giant asteroid. If someone would perfect a teleportation machine we could send them on a spaceship with robots to some to other earth like planets and then we could just teleport there.

    I think that we’re basically great apes with tremendously overgrown brains (which may or may not turn out to be a good idea... the evolutionary jury is still out), and as such, we monkey around. We puzzle and noodle and monkey around with everything, and invent so much we almost forget why we do it.

    Because no matter what we invent, we’re just apes, and so we just seek pleasure and avoid pain. We run on appetites like hunger and lust. We cheat to get more grapefruit and lie to keep them.

    We’re really smart monkeys but utter failures as higher beings. That’s why we’re both incredibly smart and soooo stoopid.

    Maybe we should send some nice guitars and amps through first then they will like us better when we get there and teach them how to play :)

    That's not the way humans operate.

    Dipping the toe into the theoretical (and science fiction) waters, IF a method to fold/warp space can be confirmed, and performed, the idea of "faster than light" becomes only a perception from Earth.
    If you had the ability to fold space by only 3,000 miles, you could move from Los Angeles to New York in only a couple of steps, so the "normal space" velocity becomes a matter of launch, landing, and local maneuvering. The actual trip would take only seconds/minutes/hours... or perhaps days.

    At that point, space debris would not be a concern... at least no more than it already is for the ISS, ESA, and NASA, as it would not be in the same "interdimensional" space as the craft.
