Exploring the Large-Scale Nature of the Universe with James Peebles

[@tehinfidel]

Thanks for making so many quality lectures and course material publicly available.

[@aidenwatler7153]

Anyone watching after his Nobel?

[@johnlandis2552]

prof. Peebles has long been one of my favorite explicators of Cosmology and Astronomical concepts

In the balloon analogy, our universe is just the surface of the balloon, not the "inside" of the balloon. Think more of galaxies as being dots on the surface of the balloon, where all dots move away from each other, with no annulus, therefore. The continuous expansion can be thought of as conservation of momentum. With nothing to stop expansion, it'll expand forever. It's been measured to expanding faster now than before, and Dark Energy is the placeholder explanation until it's figured out.

[@naturestan]

what has become3 of the large scale picture and talk about it?

[@scenFor109]

If the increasing speed of expansion measured is quantized, in steps, then it would mean that the structures used to make those measurements have lost energy, on an atomic scale, in the past ‐ even before the instrument was assembled. Anyone have a link to the following lecture?

Thanks Bernie

I have a question that has bothered me for years. If there was a single big bang and material expanded from the big bang, if the universe isn't just a three dimensional annulus (like the material that makes up a baloon), with a vacuum following the material surface outwards, then the big bang must be a continuous process providing material that follows the original surface of the material and not a single event.

[@jimhoppe6350]

Yes! Assume that size is relative, and that space will expand invisibly. The space inside an atom incurs a princely Pauli Exclusion. The rest of space expands with virtual particles; similarly the conscious seeming of the observer of such a nucleus is, to that material's expansion, virtually blind (for a purpose ala "the single Big Bang? It needs not know to be!"). To an observant galaxy space between galaxies expands, etc. The observer of one lone atom asks virtuality "Am I expanding?" (No!)

Thank you uploader.

Cabot was such a dreamer lol.

@Zurround100 Interesting comment! I also believe our Universe is an infinity this can be in the form of an infinite process. This dynamic process continuously forms the geometry of spacetime that the observer feels as the passage of time.

[@DonswatchingtheTube]

What are the forces that scientifically explain the size of the Universe?

[@Mckeycee]

Inflation and Dark energy

[@DonswatchingtheTube]

@@MckeyceeWhat are the laws that make up inflation and dark energy? How was space created?

[@Mckeycee]

@@DonswatchingtheTube I don't know that there are any laws, those are theories used to predict, describe, and match the observations seen

[@flowewritharoma]

thanks for graet contens available.

[@anonaki-mt6xb]

Boy, look at those Birkland currents ... The Thunderbolts Project )

[@ElSmusso]

The dark energy of nothingness produces exponentially more dark energy and we are in runaway accelerated situation in our universe. Scary?

“...gonna be fun”. Recruitment video?

[@moonlight.3x3]

God I love science.

[@tomp2008]

+Vanessa Constanti Science doesn't love god though!

[@muhammadalkhawarizmi3630]

+Tom P. God loves Science.

[@Dukstless]

53 minutes and 45 seconds? oh fuck.

[@tomp2008]

38:16 ... someone definitely 'gushed' SOMEthing () on that photo... fetish for men in lab coats? you decide..

[@mickmccrory8534]

I have been watching a whole bunch of these science lectures. Some concern string theory, & quantum computers, & the nature of the universe. So far, I have learned..... "The sound of the car changes when it goes by",.... Everything else is untestable speculation.

[@Kaeralho]

"BERRUM" cocky old man... great lecture tho
