the day we manage to travel faster than the speed of light, will we be able to follow a point of light reflected from the earth and see into the past?

It may be impossible to travel faster than the speed of light in a vacuum: the equations of relativity show that a greater than infinite amount of energy would be needed but ...
Light travels slower in water. Some particles emitted from radioactive materials travel faster than this speed. When some radioactive waste is stored in water a blue light is seen (Cherenkov radiation). This is light energy released as these particles spontaniously cease to exist as particles!
Now, do you really want to try it?

Einstein never said faster than light travel is impossible, only that travelling THRU the speed of light is impossible. Theoretical particles called Tachyons are believed to always travel faster than light, but sending information either direction past this barrier is not going to happen. Time allows us a one-way trip thru this great universe...enjoy!

I see your theoretical point, but the more you learn about relativity, the more you realize that traveling faster than the speed of light really is impossible. Sorry. But isn't it interesting that the stars we are looking at are actually what they looked like thousands or millions of years ago? Crazy.

You don't need to travel faster than light to see the past, I've got it on video

Travelling faster than the speed of light is impossible, so why don't you write the sci-fi book?

You can't go faster than the speed of light. It is not just difficult, it is impossible so the question is meaningless.

If I comprehend you properly, it would be impossible in a actual sense (in comparison to theoretical). it is because of the fact at a intense distance all products loose character residences. the main efficient telescopes would desire to not deliver mutually the mild had as an occasion your concept. The planets in the closest galaxies, no much less, are just about hidden from seen fact. different gadgets are had to hit upon them. In concept, in spite of the undeniable fact that, at a a ways adequate distance, the image voltaic gadget might look youthful. As you return and forth closer, the image captured might seem to alter respectively, till you attain an insignificant handful of sunshine years away. it would then look very equivalent to it does on the instant.

Yes no
You may be able to see some global things not individual stuff like you can not see the man landing on the moon etc.
But you will be able to see how much more glaziers were there before the green gas effect etc

you need to go faster than light to see time go backwards,, think about it ,,, if you went faster than light and looked behind you,, time would go backwards,,, it already had happened,, the Q is would i miss the future,,, or am i making it

i think the only way we could manage that is with mental powers, It will have to be done with will. some can already do it, i think. Read "journeys out of the body" by Robert Monroe
