I know that the universe is 13 billion years old and the fastest anything could be is the speed of light so if the universe is expanding as fast as it could be wouldn’t the universe be 13 billion light years big? But I’ve searched and it’s 93 billion light years big, so is the universe expanding faster than the speed of light?
In: 938
A recent study using gravitational lensing has provided what could be the best answer yet, though the answer in-and-of-itself is rather confusing.
The speed of universal expansion seems to be 46 miles per second per megaparsec (a megaparsec a distance of around 3.26 million light-years).
TLDR: There’s no real ELI% answer.
