It's not a silly question, so just ignore all those ignorant people who say its impossible to guess or who say its constantly changing - a human is growing atoms all the time? wow...
The answer I read is 10 to the 80th power which is 1 with 80 noughts.

Several sources on the web (google "atoms in universe") put the number between 10^79 and 10^81.
That's in the "observable universe"; the part that we can see. It is quite possible that the matter outside of our observable universe is infinite.

Sure. 10^100 is a good estimate for the number of atoms in our galaxy. 3*10^8 is one estimate for the number of galaxies in the universe. Multiply. Careful! The number is so huge your calculator might explode...

There are 10^ +56 neutrons in a neutron star.
Go to about 10^+75 atoms in the universe.give or take a few.

I'm guessing there are 10^80 particles (somewhere deep in my memory). Since most matter is in stars, and we can guess the number of stars (10^22?), it isn't that hard. But I''m pretty sure it's less than a googol, even counting all elementary particles.

its about 10 ^80 in the observable universe. thats just a guess really. most likely based on the volume of the universe and the average density. keep in mind the universe is most likely much bigger than we can observe.

Maybe 10^79, or maybe a 100 times less, or a 100 time more.

lets look at it this way.there are more atoms in a cup of water than there are cups of water in the ocean,there are more stars in the universe than there are grains of sand on earth,if you want to be the first to start counting,look up into the night sky,and tell your imagination your ready.

Yes, anybody can guess. For example, my guess is 3. How's that?

NO, and yes it's a silly question.
