Lex I love every episode you do. You are truly 1 in 8.5 billion ... But I must say the ones with Sean are my favorite. Every single one. He is one of my favorite science communicators of all time and is so well spoken.🤟

0:50 Actually that punch line shows how spiritual Albert was.

anyone have a link to the talk he mentions in the beginning "i give my talk online"?

0:31 Which Biggest Ideas is he talking about????

Edwin Hubble didn't get a Nobel prize because there are still questions and doubts raised by some people about the bigbang and the expansion of the universe. Because we currently know about only a small part of the universe (Observable Universe) and we don't know if the rest of the universe is infinite or finite and is it expanding the same way as the observable universe. We don't have any solid clue.

My question is how are matter/gravity related to the expansion of the universe? Acceleration means occupying and increasing volume of space over time and since space is expanding that means that all matter is accelerating with respect to space. Since the force of gravity is no different than the force felt during acceleration doesn't that imply that the universe must be expanding at an accelerating rate in order for matter to occupy more space over time. There must be an increase of space if there is no increase in motion through space. Also acceleration of matter must be with respect to space instead of relative to other matter because only with accelerating motion can motion be assigned to a specific body rather than both as in cases of constant velocity motion. With constant motion you can't determine which body is actually in motion but with accelerating bodies you can determine motion independently of the presence of another body. And if the acceleration of matter is determined with respect to space itself then the acceleration of space itself must also be determined with respect to matter. The two must be linked. This also suggests that space may be quantized because in order for acceleration to be with respect to space itself then space must exist in discreet units so that you can occupy a definite amount over time and the amount of force felt being equal to the number of quanta occupied above relative constant.

Is momentum descreat?

Imagine you’re dreaming from heaven!! What does that represent?? Love everyone and everything!!❤

Picture the universe as a black canvas!! A gassy state or moon!!🌚 Then we come in as the universe itself and start painting!!🖼️ We create the Earth from a single dot or grain of sand and manifest it into what we imagine it is today!! Everyone with their unique perspective!! 🦜 🌍 The earth was once a moon!! So were you and I!!🌚🌝 Now to colonize our current moon and turn it into something more, we imagine it as just another island under the sun!! 🏝️ 🌞 Wall~E vibes!! 🤖 The space between the Earth and the moon we fill in with more ocean!!🌊 🎨 🧑‍🎨 This is just one example of how we’re creating heaven on earth!! 👼 First we must become neutron stars with more of a magnetic field!! I imagine I am a neutron star, if not something more powerful!! Just I lack my magnetic field, which I believe I get more through connecting with other neutron stars!! 🐧 🐧🐧🐧🐧 Or I just do it myself by going quantum on all your asses!!👻🍆👻🍆👻🍆👻🍆👻🍆👻🍆👻🍆👻

Hahahahaha
