Why is the Rubik's Cube so Hard -- Episode 2

My facebook: http://facebook.com/redKB.FB My twitter: http://twitter.com/KennethBrandon

In this video I attempt to explain how many more positions there are on a V-Cube 7x7x7 than a Rubik's Cube 3x3x3.


How I figured this out...

For the 3x3:

4.3x10^19 Carbon atoms = .85mg (Math at 1:15)


For the 7x7:

There are 1.95x10^160 or 19 duoquinquagintillion positions in a 7x7.

According to: http://www.universetoday.com/36302/atoms-in-the-universe/ There are between 10^78 and 10^82 atoms in the universe. I used 10^80 because it worked well with my calculations.

So if you had 10^80 universes full of 10^80 atoms each, that would give you a total of 10^160 atoms, which is roughly the number of positions in a 7x7.

Now what about Oskar's 17x17x17 :)?

[vagvll]

isnt the universe supposed to have no end, if so isnt its mass supposed to have no end.

Note that he says the VISIBLE universe. Not the whole entire universe. Just what we can see. >_>"

@skewbcuber we know the average content of planets and stars, average size and number of planets per star system, average number of star systems per galaxy, and we can see galaxies to the edge of the big bang. 10^80 has been derived via multiple different calculation methods, so it is expected that this number is CLOSE for what is visible. (10^80)^2 = number of positions in a V7, or a universe for every atom in the universe, his calculations are right

Ow... Ow... oww... OOOWWWWWWW..... All of the insides hurt. All of them. From the fleshy pink think pan to the tips of my foot extensions.

@Thetrueofduty wikipedia...

[Thetrueofduty]

how u find out?

[INFERNAPE392JONATHAN]

ur smart

[UzumakiNarutoKun96]

so basicly this guy is stating that he knows how many atoms there is in 1 universe and he states that all galaxies has the same amount of atoms. -.-

the 1x2x2 has 8 posibilities :D
