Maths question

[Franconicus]

If the universe was a sphere of water with a radius of about 15 billion light years, weighing 1000kgs per cubic meter, I estimate that it would contain something in the order of 1 x 10^101 molecules of water.

2 x 10^3010 is an absurb number, so what is the point in knowing it?

Math is an abstract science. It is a logical construct. By a funny accident it can be applied to reality. Maybe the big creator loves abstract things too!

Anyway, no number is close to inf. And no number is meaningless. Just take the philosopher's approach: You can imagine this number, ergo it is!

Did you know that there is laugh 2,3,4 but no laugh 1? Strange! I think mankind could learn a lot if it could only find out why
