When do you think scientists will be able to build spaceships cabable of moving with light speed?
-------------------------------------------------------
answers:
Intrinsic Random Event say: I don't see that happening anytime soon. As Metal pointed out, our current understanding of physics tells us that moving at light speed is not possible, unless you have zero mass.
We would be lucky to be able to build a vessel that could travel at 1/4 the speed of light, powered by antimatter, which is extremely hard to create. And that would be many decades away, IF we devoted our global resources to such a project.
Travelling to another star system is extremely hard, and the proposition of that is filled with problems.
Even if we were able to build a ship that could travel at 1/4 the speed of light, we would have to deal with the fact that one single dust particle could tear a hole through the ship at that speed. And we have no idea what space is like between star systems.
I wish it were easier, I wish that we could look forward to a future like Gene Roddenberry's Star Trek predicted, but it's going to be more difficult than that.

ngc7331 say: At our current understanding, it would take an infinite amount of energy to propel even a grain of sand to the speed of light. So, probably not for a while.
-
Jeffrey K say: You can never go at the speed of light or faster. But nuclear fusion engines could get near that speed. We can't even do fusion on earth yet, so an engine using fusion is a while into the future. But I bet we will do it in the next thousand years.

Snowwie888 say: Never.
Warp drive, maybe, a very big maybe in hundreds - thousands of years. But still a big if.
-
Bill-M say: Never
-
Ronald 7 say: There is simply not enough power in the Universe to achieve that
Unless we can discover something with more power than Nuclear
-
Donut Tim say: Never.
-
Diamond-Flame of the Holy Spirit say: We already have them, but there is a cover-up by the Federal Reserve
-
Roger K say: Never.
-
Metal say: Never. The current Universe does not allow for such a thing to happen.

poornakumar b say: Telescopes don't move even at a tiny fraction of Light speed & have no control over the movement of Light that they receive. If they are made to move at Light speed, the observer too needs to move at that speed.
-
Who say: there is a difference between "moving" at light speed, and getting from A to B faster than light can
both are equally likely
-
PhotonX say: Never. If we can't figure out on some far-future day how to warp space, we'll never travel anywhere near that fast.

Hindusufi say: It's probably impossible.
-
someg say: What? Is Voyager's 17 kilometres per second not good enough for you? You can try, but you just can't please some people.
-
Acetek say: it will be a century or more. Not in your lifetime
-
timespiral say: Many of the things we do and see in ordinary life today would be pure magic to our ancestors. It would be presumptive to believe our descendants won't be more advanced than we can imagine today. 100 years ago, aviation was in it's infancy. Spaceflight is only about 60 years old. Ideas that challenge the status quo are often met with doubts and yet true innovators catapult us to higher ideals.

Grundoon say: By our understanding of science, they never will.
Until one day, they do....then we will change our understanding of science
