Perceptual Time Travel
Kind of an interesting theory of mine actually, which most have said to be very logical. I think so as well. The basics of it go like this...
If an object reflects light away from it so we are able to 'see' it, that light must travel to the viewer at a certain rate (obviously at the speed of light). The viewer then is not actually perceiving the object as it currently 'is' but rather as it was a nano-second in the past. So, in a sense you are actually 'seeing' the object in the past, but the time difference is so minimal that we discount it as non-important.
Now...let's extrapolate this idea further...
(2 basic assumptions here...one can travel at the speed of light, or faster...and we would have a telescope or something that could view clearly an object 100's of millions of miles away)
Let's say light is reflected off an object, for example, Earth and is racing away from that object at, again, the speed of light. Now you, the viewer leave Earth (which might be a good thing based on our current conditions) and are able to attain somehow, the notorious speed of light (186,000 miles/sec). Should one turn and look back at the earth while travelling EXACTLY at the speed of light, what would you see? The image presented to you would not change, would it? Since you are travelling at the same speed your view and the light you are viewing are moving along together. If one slows down...time, perceptually, would begin to move forward.
If you accellerated faster than the speed of light what would happen? Well, since you are passing up that light which left before the last segment of light you were just viewing, wouldn't you begin to watch time move backwards? So, looking back at our little blue ball rotating around Sol in our tiny little solar system, we would 'see' folks walking backwards, cars driving backwards, clocks moving backwards because the light that represents that time is still flying along...
And, go even faster...even farther away from Earth and one would see perhaps the Middle Ages being played out (in rewind of course), the age of Mohammed, the birth of Christ, Moses parting the Red Sea, cavemen learning about fire, dinosaurs, etc...
The light that left this planet 10 million years ago is all still out there...flying away from us...
It's right now about 58,656,960,000,000,000,000 miles away (that's a long damn way) and moving away .
