Question

How large is the observable universe?

Answer 1

Hint: An observable Universe may be a spherical region of the universe comprising all matter which will be observed from the world. There could also be 2 trillion galaxies within the observed Universe. Every location within the universe has its observable universe. The universe which we will observe from our planet is named the observable Universe.

Complete answer:
The universe is about 13.8 billion years old and lightweight takes time to travel through space then no matter what direction we glance we see the light that’s been traveling at the most 13.8 billion years. So, it’s logical to think that the Observable Universe must then be twice of 13.8 billion that's 27.6 billion light-years across. But that’s not due to over time-space being expanded therefore the distant objects that gave light 13.8 billion years ago have since moved even farther far away from us.
Today those objects are more than 46 billion astronomy units away multiplied by 2 and you get 93 billion light-years the diameter of the observable Universe. We are in the middle of the Observable Universe because the Observable universe is the region of the area visible from the world. The observable Universe has edges of 46 billion light-years.

Note:
The Universe is getting bigger and larger with time and that we see the light coming from farther and farther away. we will say the Observable Universe is stupendously big but the entire universe as far as we will tell maybe a lot bigger space. Space is probably going infinity and it doesn’t have edges but the Observable Universe does.
