How fast is universe expanding compared to light speed?
Can you tell me how fast the universe is expanding compared to the speed of light?
According to current estimates, the universe is expanding at a rate of about 73.3 kilometers per second per megaparsec. The speed of light, on the other hand, is about 299,792 kilometers per second. Therefore, the rate of expansion is much slower than the speed of light.
