Current predictions from astronomers puts the number of particles in the universe at somewhere between 10^72 and 10^87…
So thats somewhere OVER 100 00000000000 0000000000 0000000000 0000000000 0000000000 0000000000 0000000000 particles!
“out there” is massive, as douglas adams said “Space is big. Really big. You just won’t believe how vastly hugely mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist, but that’s just peanuts to space.”
It’s absolutely impossible to tell. We don’t know if the universe is infinite or not and it’s not possible to count all the particles!
People can estimate the number based on the mass of the sun, how many hydrogen atoms make up the sun and how many suns there are likely to be in the universe, but it’s a really rough estimate at best.
Judith is right about the numbers. But as Gemma pointed out it is very big range because no one is certain The fact that we can put a number on the total number of atoms proves that the matter in our universe is finite.
Its approximate but I did enjoy all the 0000s

@akshat I said that we didn’t *know* whether or not the universe was infinite, not that it was…
Oops my bad! I’ve fixed my answer now.
