Cosmic Inflation and the Origin of the Universe

The Inflationary Epoch happened or something nearly exactly like it, happened when the universe was extremely young. During the Grand Unified Theory (GUT) Era, the universe became the nearly flat, critical-density Cosmos we see today. In order to understand it, we have to bring in an incomplete theory: Quantum Gravity. We use this to approximate the wild phase transitions that must have occurred in order to force the expansion of space at speeds exponentially greater than light! From an early quantum foam, arose a false-vaccuum that contained all the energy of the cosmos. Oddly enough, this epoch can be observed as effects of gravitational waves on CMB. The Inflationary Epoch solves a number of problems associated with the Standard Big Bang model. It also raises some wild questions about the nature of the origin of the cosmos. This is part of my complete intro Astronomy class that I taught at Willam Paterson University and CUNY Hunter.

Thank you for all these lectures. Some over my head, have questions on some things, just love all of it. Thanks for all the work! Have seen just about all of them by now.

Seems like a lot of work just so you can make apple pie

Cant wait lets do this!

I can never understand why homogeneity is such a problem for so many physicists and cosmologists. To me, a

Thanks Jason

How can the early universe be hot if there is no particles to vibrate and the forces are undefined properties while doing symmetry breaking

Magnetic monopoles aren't possible according to Maxwell's equations. All magnetic field lines are cyclic, they do not terminate. If monopoles exist, then they must be infinitely far away. I think this has to be a math error.

The weak interaction is not mediated by neutrinos as far as I know...

Gravity is not a force. It's the curvature of space time.
