Because remember space isn't full of particles It has empty space also.

a reply to: boymonkey74

Okay agreed, but can you show me any article stating they know how many empty space we have and how big the universe is?

Don't get me wrong, I learned something new today.

I failed maths GCSE so I am not gonna search around, just a bit of fun video I thought you would all enjoy...hopefully a more intelligent member can answer your question.
I wish my maths teacher were like the guys in the video I would have paid attention .

I'm thinking he meant the "observable universe", which we do know the size of, and can calculate the total grains of sand which is actually 2.89x10^90.

He needs to choose his words wisely, and clarify he meant the "observable universe", and not the universe as a whole.

Ooh, interesting! ty for clarification, that makes more sense.

I'll just leave this right here: m.youtube.com...

I watched that also...hence my comment about the black hole in my head

Here Is the vid.

I like the video, but for me it seemed like a lot of speculating.



"say how many particles could you fit in the universe " 10 to the 80th was it? And then he goes to grain of sand and he comes with 10 of the 90th?



So a particle should be visable to the eye? Size wise? Also claiming you know the exact space of the universe seems kinda... I don't know... How?

I agree with your general consensus, however he did not state that 10 to the 80th particles could fit in the universe, but the amount of particles in our current universe matches that number. There's still plenty of room for a whole lot more particles

Well the grains of sand and the particles thing made me say "What?" out loud.

Since a particle, can be as small as hydrogen, in which case there is a best guestimate called eddingtons number which is around 2x10^80 (ish)

This assumes all matter is hydrogen. The actual evidence for it is based on the observable universe and some very rough estimates on the size of the average star, along with the average number of stars in a galaxy, and the number of galaxies that we observe. SOOOOO the error bounds are pretty big.

Then after thinking about it for a while you realize that yeah there is alot of space free space in the universe and one could probably get more than the number of particles side by side
