We're all floating brains, floating inside our skulls.

It's the theoretical physicists version of "Last Thursday-ism", the notion that the entirety of existence only started last Thursday, with all our memories also being planted at that moment.

The animation in this Kurzgesagt video was fantastic. I enjoyed its mind-blowing notions -- but maybe they are not realistic ones! The idea that the Universe did not arise from a Big Bang is kind of cool. I enjoy the notion of it being an oscillating system, for sure -- fading to near-nothing, then recreating itself, over and over.

Imagine you go to sleep one day and wake up the next day as floating brain in space

It's simple. If we are all brains floating in space, no one else is real. I can't imagine having the creativity to run this planet in the background without any thoughts.

Aint no way bro just guessed the entire content of the video at the beginning💀

Hmmm yes,our daily dose of existential crisis

If this was fully hallucinated, the laws of physics as we know them are also hallucinatory.

Have been waiting for this one :P

It's a good day when Folse uploads 😁

Sooo... If you're a floating brain, then you're probably not a floating brain, but if you're not a floating brain then you're probably a floating brain.

The main issue I have with people using “infinity” to explain stuff is that they are referring to “true infinity” whereas our world and universe and time are infinitely vast to us but in reality are finite. So yeah if everything was truly infinite, then yeah of course a monkey at a typewriter could type out anything you want but in reality it’ll always be gibberish. Same concept with the floating brains, according to our understanding of the universe there is no true infinite.

That video made me feel like an acid trip. Not feeling it, but being it cuz I'm cool like that

Idk why but there’s something funny about the sentence “infinite time, it’s happening”

Some people have very smooth floating brains.

9:04 organic, locally grown, free range universes

The whole monkey typewriting example reminds me of another one that is used as an analogy to parallel or alternate universes which compares matter and energy to a deck of cards. If space is truly infinite but the number of particles and their configurations are not, then like a deck of cards, an infinite number of shuffles will eventually cause repetitions to appear due to their being a finite number of card types. So over an insane number of time and configurations, there might be a me that thinks its the only me but is one of many. The Many Worlds theory is a similar take that expands by adding choices, movements, probabilities that become impossible to calculate for every scrap of matter and energy. I will never claim to understand science at this level but its still very cool to see that what is considered absurd and illogical is based on a growing foundation of actual math, theory and eventual proof from experimental science.

3:00 of course there is. Any energy well can be tunneled into with enough tries. It's just stupidly unlikely.

Imagine if there's alien and they see us playing with this thought, what would they thinking about us
