-_- it’s extremely disappointing to see the number of articles claiming a time reflection mirror would,let you see the back of your head, for example (1):
“ In the acoustic version of this observation, you would hear sound similar to what is emitted during the rewinding of a tape.”
Yes.
“As a result, if you were to look into a time mirror, your reflection would be flipped, and you would see your back instead of your face.”
No.
That is not how it works.
Practically speaking what you would see is a frequency shift (color change).
Where does this bs come from?
Reversing a light signal (light bouncing off your face) does not result in a signal that doesn’t exist (light bouncing off the back of your head). This is just absolute nonsense. If no light bounces off the back of your head, there is no possible way to make light bouncing off the front of your face transform into the former… unless the front of your face and the back of your head are indistinguishable.
There’s science reporting trying to explain complex ideas in simple terms, and there’s just making stuff up. :|
Read the paper (2).
“At such a time interface, a portion of the input signal is time reversed, and its frequency spectrum is homogeneously translated as its momentum is conserved, forming the temporal counterpart of a spatial interface”
