Can space expand faster than light during inflation?

hobobobo · Apr 15, 2008

I have a question about inflation. I read that during inflation the speed which is expanding is greater than the speed of light, is that even possible? We know that nothing in the universe is faster than the speed of light.

Yes, the speed of expansion of the universe was (not sure, but might still be) faster than the speed of light.
Einstein's relativity equations say that no information may travel faster than the speed of light, but the universe itself may expand faster than this speed. After all, nothing is really moving at all, the space in between everything is just stretching, creating the illusion of motion.
