As a matter of fact, I am a physicist
If you actually undestood the equations you're throwing about from special relativity, then you'd understand that they do not permit backward travel
through time, only the relative slowing of time from one observer relative to another, provided they are travelling slower or equal to the speed of
. There are other, more important reasons for us to believe that it is impossible to travel faster than the speed of light: it is kind
implied in the definition of what space and time actually are.
As a physicist, I know that in order for time travel to happen, the universe must permit closed timelike loops
in our spacetime topology. In
fact, our theories permit this. Time travel is not impossible, according to some physicists. Now you must note that we are not dealing with special
relativity, as per your equations, but with the spacetime geometry of general relativity, which was Einstein's lasting contribution to physics.
Now, while closed timelike loops are not impossible, they do certainly require extremely exotic configurations of matter and energy (wormholes,
"Einstein-Rosen bridges"). For example, it has been postulated that time travel might be possible if we as a civilization were able to engineer a
massive, rotating neutron star cylinder, and then dip in and out of its event horizon in space ships. I shouldn't have to explain that this would
require a type II civilization (on the Kardashev scale) at the very least- in other words, millions of years beyond what we even think is possible,
Nevermind the fact that such a wormhole would induce extreme gravitational tidal forces at the point of its entry and exit that should make traversing
it impossible. If you created such a thing at the surface of the earth (which , given the energy density required, should be
impossible) it would destroy the earth itself!
Lastly, any such closed timelike loop would only permit the travel of persons and energy from the future to the point at which the machine was first
turned on. You cannot travel back to an arbitrary point in time. Nevermind the fact that you would have to involve cosmological scales of energy.
Do I even have to explain that if you were to create such a time machine on Earth that it would likely destroy the planet entirely? Do you even
understand why this is true?
So don't mind me. Obviously I'm just talking #. All the proof you need is in this one old piece of video footage of one person acting kind of
strangely for her time period.
Obviously the only possible explanation is time travel.
