How big is the universe in meters?

1 Answer

The diameter of the universe is approximately #871 xx 10^24# meters.

Explanation:

Which is #871# yottameters or #871# septillion.

I actually calculated it about #870898760# exameters.

And it is still expanding at a rate of #74.3 +- 2.1# kilometers per second per megaparsec ( according to the data I've known earlier) and it's still accelerating.
