How fast is this universe expanding?
It should be expanding at the speed of light. Universe cannot expand faster than the speed of light, because that would mean that the particles at the theoritical edge are travelling faster than light. That cannot be possible.
It cannot be slower than light, because light is a particle wave. So where there is light there are bound to be particles.
So universe must expand at a speed that approaches that of light.
Then again who knows if light speed at the end of the universe is the same as the speed here? It could be faster or it could be slower.
These are some questions which never can be answered.... or so I believe
