speed of light travel = possible?

aliens millions light years away looking at earth can only see dinosaurs. if the telescope is strong enough

light speed still sucks

wonder if this is how we will meet an alien civilization? aliens send their ships looking to colonize expecting only dinosaurs and prehistoric animals and SURPRISE. there are actual people here.would be somewhat awkward.

well first u have to prove general relativity wrong, then maybe.

If a concept is possible with physics than it is just a matter of time. If a concept is impossible in physics, it's impossible. implausible is just an idea which has no proof or rejection by physics. You can not put a percentage next to an improbable idea.

What about something that can happen theoretically given some mathematical conditions, but there is no evidence that the universe actually behaves that way? The classical Closed Timelike Curve is an example. You can solve the equations to create time travel, so it's not impossible in physics, but the universe doesn't appear to work that way whatsoever.

Example warp drive has long been know to be possible, but it had a key flaw in physics that said it was only a probable idea. But a couple of years ago it was proven that it was not only possible but cheap in energy, right not NASA and several different space agencies are trying to design a working model.

No, it's not "known" to be possible, it's speculated that it could be possible - if a certain something exists that behaves in a certain way. Refer to my original reply on this.

Pretty sure any civilization advanced enough to build faster-than-light interstellar ships will probably know how light works and won't be expecting dinosaurs.

The theory about traveling through time the closer you get to the speed of light is very intriguing, so intriguing that they made this awesome clip about Steven Hawking's spaceship idea.

Given any chance in an near infinite universe mathematically means it has happened more than once.

well thats not true.
Random folding of a medium sized biomacromolecule, so that its structure would allow its known function, would take longer than the universe exists.
In fact, thay dont fold randomly, but by the law of physics and chemistry, and very fast.

This article has nothing to do with space travel or speed of light. Sadly, we are not electrons.
