What is a Scientific Fact, that while you know it has been proven true, still seems impossible?
@RickiTarr that the universe exists at all
@MishaVanMollusq When I started learning how galaxies and planets were formed, it was like like WTF?!
@MishaVanMollusq @RickiTarr
Once you learn about the Penrose number you kinda stop believing that it's real at all. It's absolutely insane.
@Basmitharts @MishaVanMollusq @RickiTarr
Okay, I googled it.
Still don't know what it is.
Our did you mean the sheer number of things Roger Penrose is known for.

Definitely, but TL-DR it's essentially is the measurement of how ordered the universe had to be at the beginning to evolve into what we see today.
Comes out to a 1 in 10 to the power of 10^123 chance.
@MishaVanMollusq @Basmitharts @MennoWolff @RickiTarr I just felt my brain nope out of that

@MishaVanMollusq @Basmitharts @MennoWolff @RickiTarr And that's another thing --

That a brain can develop squick points, and mental models, and artificially impose limits on itself. Being "inside" a brain can feel so limitless, but isn't...but then again, some of the limits are fake and self-imposed.

Our brains don't seem to cope well with the limitless. So it makes up limitations, and then tells itself that it is, in fact, limitless. All while pretending that it isn't blocking out information.

@Basmitharts @MennoWolff @MishaVanMollusq @RickiTarr
Huge odds, but if you don't have time yet, surely you can crack off 10^10^123 universes before breakfast. If there's a way to make universes (which there obviously is) but time doesn't exist yet, just keep banging them out until one works.
@Naich @Basmitharts @MennoWolff @MishaVanMollusq @RickiTarr just break out your Sefer Yetzira and hum a tune until you can fake it
@MennoWolff @Basmitharts @MishaVanMollusq @RickiTarr I thought this might have been a play on the original meaning of "google".
@hosford42 @Basmitharts @MishaVanMollusq @RickiTarr
TIL that you're off by only 10^23.
Avogadro's number, roughly 😃
@MennoWolff @Basmitharts @MishaVanMollusq @RickiTarr It's a sign! One that reads "Numerology". :D

@Basmitharts @MishaVanMollusq @RickiTarr How real is any number, when you really get down to it? (My god, it's full of puns! Sorry, distracted myself from my point for a moment there. Ahem...)

Our entire number system is really just a model with properties that make it conveniently reusable in a lot of different contexts. The really outlandish numbers like this are exactly the sort of thing we should expect when we let a power user play around with it.

Reality is vast and profound, and our system for describing it can be a little inadequate sometimes. But it's not the number that's outlandish. The real outlandishness is in the universe we are trying to describe with it.
