No one knows if the universe is infinitely large, or even if ours is the only universe there is.
But since the Big Bang (when the universe is confirmed to have begun) it has been 13.7 Billion years. And therefore light has been traveling for that long as well.
Many state the entire Universe is flat, or spherical.
So measuring across our known universe and taking into account 'rapid expansion' and dark energy accelerating expansion, scientists estimate the size of the universe to be about 156 Billion light years across (end to end) and expanding!
We live in one of the 100 billion known galaxies in the Universe.
Our galaxy is called the Milky Way (I know, sounds a bit silly)
Our solar system (Earth, Sun other nearby planets etc etc) would be smaller than an atom when compared to the entire size of just our own galaxy! On a clear night, if you look up, you'll see only 0.000003% of all the stars just in our galaxy!
There are billions upon billions upon billions of other galaxies out there. Each with up to hundreds of billions of star systems and their trillions of planets! Is there likely to be other life out there?
The number you stated is ~ 390 Dodecillion (a number with 40 zeros after it)
Your 13.7 Eons = 13.7 Billion years = 13,700,000,000 years
Although, the amount of stars, planets etc would be far more than 'Dodecillions' anyway.
My wording on previous post stated:
billions upon billions upon billions of other galaxies out there. Each with up to hundreds of billions of star systems and their trillions of planets
ie: Billion x Billion x Billion x 100 Billion x Trillion
= 100000000000000000000000000000000000000000000000000 (Which is a number with 50 zeros after it!)
I think I may have been conservative though.
I'm sorry, your quoted number was over 10 Billion TIMES too small.
Regarding space and galaxies etc, Eon = Billion
ie Our universe is 13.7 Eons (although I never say this, because Eon is very subjective, ie it can also mean forever)
Do you think Aliens truly exist?

i believe is 13.7 EONS since the big bang (exactly 390004384278436833798053383779983583292680001 years) i just played my "i know every thing" card.

Hi just logged on sorry for the wait.
Regarding space and galaxies etc, Eon = Billion
ie Our universe is 13.7 Eons (although I never say this, because Eon is very subjective, ie it can also mean forever)
