Answer:
1. 2*10^10 light years
Explanation:
The observable universe is a spherical region in the universe comprising of all matter that can be observed from Earth or spaced biased telescopes.
The word observable in this sense does not refer to the capability to detect light or any other information from an object, or whether there is anything to be detected.
It refers to the speed of light itself, because no signals can travel faster than light.
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs.
