Not exactly. It would be paradoxical and thus simply not possible. If it moved backwards it wouldnt be going forward FTL in the first place :) Tachyons cant be observed at all unitl it passes so you dont see them, if they even exist (probably not). What you would see, however, is once they pass a double image of them moving in both directions away from you.
@freemo @thatonecalculator @Arcana ok but in this case the supposed FTL object didn't pass you, it hit the Earth and stopped. So you would see it some time after it stopped, and then you'd see it going backwards where it came from, right?
Since that's not what's in the picture, therefore the asteroid is not depicted as moving faster than light.
I said appears to move FTL, not that it actually is moving FTL. As in the rate it moves across the earth at earth scale is FTL.
@freemo @thatonecalculator @Arcana idk to me it appears like the whole thing must be smaller because it does not appear like am FTL object
@freemo @thatonecalculator @Arcana I think we're arguing semantics of the word "appear"
To put it another way, we should not be able to see what we are seeing
@freemo @thatonecalculator @Arcana if it did, wouldn't you see it go backwards?
