Well I'll tell you one thing, I'm not going to do a physical count to check if C4M is right or wrong.

Anyway, you've all missed one crucial point, the question, if you would care to look, is 'How many attoms are in the universe?"

So why are you all postulating about how many atoms there are in the universe???

Post by: preeti28 on 09/08/2010 12:05:41
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.)

Title: How many atoms are in the Universe?
Post by: chemgeek on 13/08/2010 18:48:58
I know wikipedia isn't the most reliable source in the world but this was quite inteseting:

Two approximate calculations give the number of atoms in the observable universe to be a minimum of 10^80.

1.Observations of the cosmic microwave background from the Wilkinson Microwave Anisotropy Probe suggest that the spatial curvature of the Universe is very close to zero, which in current cosmological models implies that the value of the density parameter must be very close to a certain critical value. This works out to 9.9×10−27 kg/m3,[25] which would be equal to about 5.9 hydrogen atoms per cubic meter. Analysis of the WMAP results suggests that only about 4.6% of the critical density is in the form of normal atoms, while 23% is thought to be made of cold dark matter and 72% is thought to be dark energy,[25] so this leaves 0.27 hydrogen atoms/m3. Multiplying this by the volume of the visible universe, you get about 8×10^79 hydrogen atoms.
2.A typical star has a mass of about 2×10^30 kg, which is about 1×10^57 atoms of hydrogen per star. A typical galaxy has about 400 billion stars so that means each galaxy has 1×10^57 × 4×10^11 = 4×10^68 hydrogen atoms. There are possibly 80 billion galaxies in the Universe, so that means that there are about 4×10^68 × 8×10^10 = 3×10^79 hydrogen atoms in the observable universe. But this is definitely a lower limit calculation, and it ignores many possible atom sources such as intergalactic gas.[26]
