Yea, I kinda like how most things that we first thought infinite, just arent xD
I remember thinking of haw many sand grains would fit into the universe, then I cam across Graham's number.
To answer an old question, I'm gonna calculate how many grains of sand fit into the universe xD
It's 156 billion light-years wide according to Space.comhttp://www.space.com/scienceastronomy/m ... 40524.html
So the radius is 78 billion light-years
A grain if sand is 1×10^-13 m³ according to WolframAlphahttp://www.wolframalpha.com/input/?i=vo ... in+of+sand
So first we calculate the volume of the universe (assuming that it's a perfect sphere)
V=4/3 * pi * r^3
With v as volume and r as the radius.
the r in meters is 7.379×10^26 meters
so: 4/3 * pi * (7.379×10^26)^3 = 9.467*10^80 m³
Then Vuniverse/Vsand =
9.467*10^80 / 1×10^-13 = 9.467×10^93 grains of sand in the visible universe.
Thats 950 nanoGogols O.O
A Googol is a 1 with a 100 zeros behind it.
Google said that a grain wighs 0.67 mg so 0.67* 9.5E93 = 6.343*10^87 kg
Thats a LOT of sand xD
