Cosmology | Lecture 7

Lecture 7 of Leonard Susskind's course on Cosmology. Recorded March 9, 2009 at Stanford University.

This Stanford Continuing Studies course is the fifth of a six-quarter sequence of classes exploring the essential theoretical foundations of modern physics. The topics covered in this course focus on classical mechanics. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

thanks for these lectures, prof. L.Susskind is virtuoso in his field

[MartinBaco]

Despite my education in different field of science with little knowledge of theoretical physics I think I'm able to follow for me very fascinating and surprising story of early phase of the universe and how primordial fluctuations of quantum mechanic scalar field observable on the surface of last scattering became seats of galaxies-islands with magnified energy density-as result of rapid slow down of space expansion at the end of inflation phase and transform.of accumulated energy into particles

This is really a great surprise for a cosmology class.

Developed a huge lump in my throat...when Susskind ...finished unpacking this amazing scenario...which concluded with "the seedlings of galaxies"...what .an emotional crescendo....you're a genius ..Leonard!

@fuzzface89 Why, do you feel something unusual when you listen to my favourit list?

[fuzzface89]

@MartinBaco nice one now tell me about teleportation, thanks

[dillinger9999]

I read his book. He's very good at explaining Physics

Watching Leonard Susskind free associate and perform thought experiments in real time is a joy.

@ 40:51 Prof. Susskind says," ...erases all the information about how it started" with respect to the initial conditions of the universe. Is not Susskind's hypothesis in his book 'The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics' prove that information is never lost? And this is why he proposed his famous holographic principle? Perhaps I am not comprehending the cosmology well enough at this level. Just asking...lol.
