OK, so let's have some random facts! According to Wolfram|Alpha, we have
Age of the universe = 4.32 x 10^17 seconds
Size of the (observable) universe = 8.8 x 10^26 meters
Content of the universe = 10^80 atoms
(I can't seem to find an estimate for the number of subatomic particles
in the universe. Since the universe is 75% H, 23% He and only 1% O, I
guess there isn't going to be a huge difference - unless you count
non-matter particles like photons, etc.)
I can't actually find anything as big as 10^100.

You forget the hypothesized dark matter.

Ah yes. If we could just figure out what the hell this stuff is made of,
I could factor it into the calculations...
(Personally, I'm still curious to know how they know the universe
contains 10^80 atoms and not, say, 10^81 or 10^181...)

If that's your goal, easy: Volume of universe ~ 10^185 lp^3 where lp is
Planck length.

Averages based on known densities and an estimated volume of the
universe, probably.
Either that or they just made up an answer and figured the pool of people
who could refute their answer is very small.
You know that 78.67% of all statistics are made up, right?

I heard it was 82.1%...

No, new research has shown that (statistically speaking) fewer statistics
are made up than was previously thought. :-)

One in five dentists agree.

62.3% of the time, in any event. :-)

I wonder how many photons typically exist? I mean is it 10^10, 10^50,
10^100 or what? You could probably do some estimate with output power from
stars etc.
