Is expansion of universe faster than the speed of light?
That's fascinating! How is that even possible when nothing can travel faster than light?
The expansion of the universe is not limited by the speed of light because it is not the movement of matter through space, but the stretching of space itself. This means that galaxies and other objects in space are moving away from each other faster than the speed of light due to the expansion of space.
