Sean talks just like Chef John from Food Wishes

Why does he remind me of the concierge Hector in Home Alone 2

It is mind boggling how ancient Greek scientists had actually conceived key physical properties, but essentially did not have the math to describe it. Democritus conceived the atom. Even more impressive is Heraclitus "everything flows" axiom that essentially describes that the universe is in constant motion, actions and reactions are relative to the perspective of the agent experiencing it. He also described the deterministic nature of the flow. This is the fundamental principle of general relativity, essentialy gravity is the effect of mass in space during motion through it and time is the moment of that motion. Time is deterministic only because of the direction of motion in space. Heraclitus described this deterministic idea in relation to life experiences, but I think he hinted that this applies to the cosmos, as the motion of planets is constant, even though at that time only the Pythagoreans and later Aristarchos proposed a heliocentric model.

Yeah Whoopi Goldberg is really hard to figure out..

What if our math (or understanding) is just an infinitely small fraction of nature's MATH? #Gödel

It is a bad sign if physicists think they are close to understanding black holes, given that ‘we’ only just imaged one for the first time a few years ago and have gathered so little information on them. Physicists are almost entirely in the realm of forming initial hypotheses about black holes and have not really begun testing those hypotheses.

Like trying to describe an excessively attractive woman with all her quarks. 😅😅😅😅😅

[LOTUG]

Nobody has any idea at all about anything beyond this world.

[solvingpolitics]

I always found black holes not as exciting as other astronomical objects. Probably because you can’t see them.

[Stucknthez]

He is just trying to sound smart when he has absolutely no clue

[jaydlynch]

Time ABSOLUTELY doesn't exist at all. Movement is everything. We are now, everything is now. Distance makes now relative.
