Answer:
What if mirrors are windows to parallel universes and the reason we can’t go through is because our parallel self keeps blocking our every move? Is that a good theory?
This is the Lunar Liquid Mirror Telescope.
Instead of using a solid mirror to observe the stars, NASA instead opted to use a liquid mirror, which is much more reflective and effective than a solid telescopic mirror.
It’s like a hyper-reflective pond.
According to your logic, my ‘parallel’ self physically blocks all of my attempts at accessing his universe and he perfectly mirrors my movements, correct?
So if I stand on this liquid mirror, my feet and my parallel self’s feet will touch each other oppositely. And so, if your theory is true: I should be able to stand on it.
But of course, instead of becoming Jesus, I’ll sink into the liquid, make myself look like an idiot, and completely ruin an expensive scientific instrument in the process.
