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.
I'm glad that you came to this lecture. It raises many questions that are hard to understand. You know, of course, that photons in the interior of our sun takes about 4,000 years to emerge from the surface. It's like that.
It’s maybe helpful analogy by Feynman and his little kid who couldn’t think of the word he needed cuz the word bag in his stomach was empty. Photons are like words that exit your mouth… they are not trapped in your body somewhere … they are created by the field… so that excitation did not occur before that 380k mark of time due to temperature
At some point in time, electrically neutral atoms were able to form, and that's why space became transparent to light. Before that, electrically charged particles scattered photons by constantly absorbing and reabsorbing them
@@RicardoMarlowFlamenco that does not make sense to me. Photons had to exist since there were electrical charges everywhere, and photons mediate em force and are product of electric field. photons were scattered by those electric charges before, and released to travel in straight lines at 380 years mark, when protons and neutrons neutralized by forming atoms. That's why em force is not dominant since then, and space is transparent to light
@@dmitryshusterman9494 if this is about how differently charged particles attract and repel each other, ok I understand that. But I still don’t understand what difference it would make to a photon whether space was/is opaque or transparent. It matters to us - in terms of observation - but why does it matter to a photon?
You would think at some point in his life someone would have told him he had a dreadful verbal tic “uh”. I quit after 4 minutes. I couldn’t take it anymore.
It is ironic that the youtube image of this video displays a picture of a water ripple. I have been trying to convince the physics community that the building blocks of spacetime should be something similar to ripples. But so far... no comments.
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?
One of this planet’s friendliest geniuses
this professor is my favorite scientist ! such a brilliant mind !
Yes 👍 Why is he your favorite ?
Really enjoy this keep them coming !!!!!
Fantastic theory and lecture, thank you👏👏👏
If susy exist at what point would they have formed? After recombination would regular particles form?
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.
That was awesome!
Fascinating thanks!!
Right from the beginning he overturns most of what I've heard about inflation and the big bang.
Where do the photons come from before recombination?
From particles no longer existing in thermal equilibrium.

Is 10 to the minus 38 seconds one planck time?
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.

Why did that girl have to stand at the door the whole time??
Girl? Are you a biologist?
It's only a matter of time that Guth finds something to fill that empty cube...

Cosomology? Is that the study of the Cososm?
Uh... I like it
Immediately
Great Sci-Fi story. The Flying Ball Circus rides again. :)
Amazing Neanderthal comment. Don't forget to shave your unibrow
Let me guess, the universe was created 6500 years ago by god?

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

A brilliant mind, often these individuals have tremendous social quirks or quarks ;)
I could never attend a class at MIT with Prof Guth, he lost me in like 1 minute.
