It doesn’t interact with ordinary matter, or it only interacts very weakly. So a mirror photon would pass right through you.
We know there are particles out there that interact very weakly with other forms of matter, neutrinos being one type. So it shouldn’t surprise us there are others — and maybe lots of them. Doesn’t prove mirror matter exists, just sayin’. There are a lot of strange things out there in the Big U.
Or do they exists in mirror space which is different from our space?
Mirror spatial and temporal dimensions, but gravity bleeds over?
You would think mirror gravity caused by mirror matter wouldn't bleed over either.
I think I just confused myself :^)
