> While objects cannot move faster than light, this limitation only applies with respect to local reference frames and does not limit the recession rates of cosmologically distant objects
Given that v is velocity in the opposite direction, and c is the constant reference frame speed of light; do we account for velocity in determining whether light traveling at c towards earth will ever reach us?
v - c < 0 if v>c
v + c > c if v>0
Are tachyons FTL, is there entanglement FTL?
How far away in light years does a mirror in space need to be in order to see dinosaurs that existed say 100 million years ago?
