  • Anyone else see a spider on the "insect" bubble? lol

  • I would love to hear you explain the eleven dimensions that your string theory is based off of.

  • lol i like his metaphor for worm holes its kinda the same thing but its nothing like the real thing and yet it still is the same thing... this could go on forever

  • wtf does this have to do with strings?

  • wormholes should be called rabbit holes

  • can a type 2 civilization survive a big freeze? I think that shoots down that immortality... perhaps a type 4 civ can, because that logically implies universal or maybe multiversal mastery

  • @Diomedes01

    Nothing guarantees that we hit a habitable universe the first time. But through some pretty sneaky probability you can come up with that it is a 50% chance to hit a universe just like our own, since every infinity will always take up half the set, while those not like it take the other half and share it.

    I know it sound confusing but so does Quantum mechanics which is actually what is being used to come up with the ratio.

  • escaping the universe...holy balls

  • @vegasx9 was gonna say...

  • His voice cracked so much in this video
