WSU Master Class: Inflationary Cosmology with Alan Guth

Breakthrough Prize winner Alan Guth developed the theory of inflation to answer to our cosmic origins. It's one of the most studied and debated theories in cosmology, with research propelling Guth’s work to the forefront of scientific conversation.

In this Master Class, Professor Guth addresses what experiments could potentially rule out the BICEP2 results. Since recording this in 2017, the Planck spacecraft collected the data that Professor Guth anticipated, which shows that the initial observations were likely an artifact of interstellar dust, not primordial gravitational waves.

This lecture was recorded on xyz at the World Science Festival in New York City.

Why did that girl have to stand at the door the whole time??

[peterpalumbo]

If susy exist at what point would they have formed? After recombination would regular particles form?

[AlejandroFernandezDaCosta]

Fantastic theory and lecture, thank you👏👏👏

[Techno.love]

this professor is my favorite scientist ! such a brilliant mind !

If all theory is a Sciencing Test design of real-time Actuality, then the Student's first principles learning objectives are to collect and collate the work of Peers in professional expertise, and .."just look at it".. from experience in a combined POV, the natural "Apprenticeship" approach from recognised re-evolution techniques. "In Theory", self-defining AM-FM reciprocation-recirculation Logarithmic Actuality, is this Observable Eternity-now wave-packaging Singularity projection-drawing holography, Spacetime Relativity Interval and WYSIWYG QM-TIME functional e-Pi-i condensation-concept Conception, resonance bonding sense-in-common, Completeness.

Professor Guth has illuminated the e-Inflation aspect, Dr Disney the Logarithmic Time Duration in Pi-bifurcation location aspects and together with Dirac's reciprocals of large number features, fits Euler's e-Pi-i 1-0-infinity instantaneous Perspective probability sync-duration Form-ation.., set in time-timing Cosmology.

(If you look, listen, hear and see what that means under the circumstances, Logarithmic Time made of making Fluxion-Integral Calculus)

"Within ABOUT ten to the minus thirty five seconds OR how inexact is that haha, I mean I don't want to be kept unnecessarily waiting for the big bang to end

[snowpants]

Right from the beginning he overturns most of what I've heard about inflation and the big bang.

[SudheendraRao]

With my limited understanding, I am thinking BICEP2 and NANOGrav results are something to pay close attention to in coming days, to get a better picture in the inflation vs Big-Bounce debate.

[tomasasompolinsky]

If I aquire kinetic energy from falling into a large mass that energy came from somewhere. It balances out the energy increase in negative energy.

[AzimuthAviation]

It's only a matter of time that Guth finds something to fill that empty cube...

[kevinhanley]

Where do the photons come from before recombination?

[andy]

Is 10 to the minus 38 seconds one planck time?

[pg]

Cosomology? Is that the study of the Cososm?

Great Sci-Fi story. The Flying Ball Circus rides again. :)

[KaliFissure]

James Peebles doesn’t believe inflationary model. Why do you?

[ryanrussell]

I could never attend a class at MIT with Prof Guth, he lost me in like 1 minute.

[nmanon]

He talks about the uniformity being confirmed by photons on their journey on a straight line because the universe (at that time) after 380k years switched from opaque to transparent.

Does he mean to imply that the photons accidentally ran into the electrons when the universe was opaque because they couldn’t see?

I don’t see how it matters if it were opaque vs transparent. Especially when nothing cared (at the time) about seeing the photons. I’m left w the impression that these photons were smart enough to avoid electrons in a transparent universe.

Alan, let me help you with the words, "I . . . made . . . a . . . mistake." See how simple that is? There's no need to make up fictional metaphysics, is there?
