How many atoms in the universe?
Asked in Astronomy, Physics
How many atoms are there in the whole universe?
How many atoms are there in the universe?
The visible universe is estimated to contain between 1078 and 1080 atoms. (One estimate at the higher end of the range is 4 x 1079.) This is the estimated number of atoms in the observable universe, but since we do not know the absolute size of the universe, we cannot be certain. (Most of the matter in the universe is still hydrogen.)

How many molecules fit into the universe Estimate please?

What are the most common substances in the universe?
How can they estimate the number of atoms in the universe?
The no. of atoms in the Universe is not estimated yet because till now we are not able to calculate the amount of matter present in the universe and what is the exact percentage of each element in the universe. Once it is calculated, scientists would be able to calculate the no. of atoms in the universe.

What is the basic unit of the universe?
The atom is the basis of everything. Atoms themselves are made up of different particles, but particles are not 'solid stuff' and atoms are. Everything which we can see - unaided - in the universe, is made of atoms. Without "solid stuff" we would not be here to observe whatever universe might otherwise exist in a 'particle-only" universe.

How many atoms in the univearse?
There is an infinite number of atoms in the universe. This is because the universe never ends, it is always expanding. So, since you can't measure how large the universe is, as it is ever-expanding, you cannot determine how many atoms are in the universe. alternate view. Though the universe may be infinite, that is not the same thing as boundless. And of course most of the universe is space without matter in it. Astrophysicist Arthur Eddington estimated the number of hydrogen atoms in the Universe to be about 10^73, and even with knowledge of 'Dark matter' that would only add a few digits to the exponent. Today's best guess along those lines is around 10^80. (Also known as the Dirac large number hypothesis.) This is a long way from infinite, and even a long way from a Googol or a Googolplex.
