# How is the size of the unobservable universe calculated?

##### 1 Answer

please see below

#### Explanation:

I percieve your question to be 'What is the size of our universe?'

Rather than size of ** observable universe** .

Size of universe is yet undefined , some say it is infinite while the others sughest that it must be finite but an extremely large value .

Perhaps, we know size of observable universe that's around 94 billion light years .

Space is expanding into itself , it seems just like if you zoom the graph at "desmos.com" .

know why i said rather typed "our universe"? that's because some astronomers suggested existence of more than one universe , isn't this stuff cool?

Dark energy is believed to be alien to our universe .

So, yet the question is pending , How big is

To answer that we need to know how ** old** is our universe ,

If we know how much old it is we need to work out some calculations based on ** entropy** and

**, may be yielding some result ..**

*red shift*Actually this stuff isn't yet as simple as i told ,

"Any other challenge left?"

Yes, The worst part of astrophysics comes in when you see some equations with so many variables denoted by greek alphabet , no need to get dissapointed for now , i heard a quantum physict say that those equations are not really boring or dangerous , whatever! as they seem to be.

What about answer to question ?

I got no idea but just a mind to think about it!
