Very interesting docu, I like what they say, but the universe can't be infinite of its originated from a point. Unless they mean the empty space with literally nothing in it

Who says that the universe had to have a point of origin which is finite?

Most current-day cosmological theories

Which are based upon our impossibility to imagine infinity...

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.

Edit:

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.com
http://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 WolframAlpha
http://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

But still not an infinite amount, you see, that's where our theories of cosmology go wrong, we can't imagine that something is really truly infinite in time, space or some other entitiy

Yea, I can't really think of anything thats infinite.
