This is what most 4 year olds imagine that mathematicians do for a living. They get into an arena with screaming crowds, and have a competition for who can think of the biggest number.

[mohnjilligan]

Imagine is Adam Elga had accidentally erased that second 1 and ended up writing and lost immediately

[jacobparasite]

Am absolutely shook after that factorial move. Is this an anime?

[theCodyReeder]

I would have conceded defeat after the 2nd move.

[FanTazTiCxD]

Rayo said, calmly. Elga screamed at the top of his lungs.

[sadas]

"That depends on the nature of dark energy" is now my go to response for any question I don't understand.

[pendragk]

"So can I write this number down, professor?" - "Well, that kind of depends on the nature of Dark Energy."

[Verlisify]

Rayo: Makes the biggest number ever
Comments section: Yeah... but the other guy did the factorial thing

[TheAlps]

Sounds like a grown up version of "I hate you x20" "I hate you x1000"

[mmusthofa]

When two kids wouldn't give up and keep on increasing their own dad power level

[lars]

14:14 I love how Elga is standing there for eternity as all the fans have left, watching Rayo writing away his defeat

[MechMK]

"So how fast can you write one symbol?"
"I don't know, depends on the symbol. I'd say maybe a seco--"
"About one Planck time"
"O-Oh! A bit faster than me apparently"

[mastershooter]

rayo: *writes down many many 1s

elga: im gonna what's called a pro gamer move

[Rafael-pimd]

you know things got serious when the participants of the big number duel are philosophy professors and not math professors

[JMUDoc]

10:15 - If you're wondering how that lot defines "zero", it can read literally as
"There exists a set x1 such that there exists no x2 that is a member of x1."

Basically, there is a set that has no elements.

Rayo:
Elga:
Ron: Well that escalated quickly

[JoshuaWillis]

Rayo basically “+1”ed all of mathematics, which is genius.

[mitsterful]

I really love the idea of the guy just drawing a line through all the 1's to make a string of factorials. That's so clever and elegant.

[metleon]

Sonic the Hedgehog: I'd better not run too fast or I'll create a sonic boom.
Tony the Planckwriter: I'd better not write too fast or all of physics will collapse.

[sanketower]

"But we can write it down"
I like his enthusiasm
