MIT 8.286 The Early Universe, Fall 2013 View the complete course: http://ocw.mit.edu/8-286F13 Instructor: Alan Guth In this lecture, the professor summarized the standard Big Bang, cosmic inflation, evidence for inflation, inflation and multiverse, nightmare of dark energy. He also talked about the landscape and environmental selection, anthropic arguments, etc. License: Creative Commons BY-NC-SA More information at http://ocw.mit.edu/terms More courses at http://ocw.mit.edu

I love listening to Professor Guth however after the 200th "uh" in-between almost every sentence it begins to wear on me.
-
Fuck Hubble's Law. Ain't no white man gonna tell me what to do.
-
Is the entire mulitverse (if this theory is correct) 14 billion years old, or is it only our pocket universe that is 14 B years old? I watched another video from Dr. Guth an got a mixed answer. Thanks in advance.
-
in minute 31, professor Guth said that weinberg and his collaborates calculated the effect of IS on galaxy formation .. they said it's about a factor of 5 or so .. I didn't get it .. a factor of 5 or so of what? please anyone has an answer ?
-
In this pocket universe of a larger Youtubian multiverse , how unlikely is the dislike parameter to be zero and what divine selection helped you land here ?
-
The Cosmological Redshift is NOT a doppler shift. Amazing how so few get this correct, most textbooks are wrong about this
-
So much information on MIT... I wish i was a particle in a quantum state so i can watch them all at once.
-
What a tremendous gift these lectures are. Professor Guth is very patient and respectful of all questions and attempts to answer each one sincerely while gently dispensing with the many misconceptions (many of mine own).
-
have just checked Wikipedia as per Guth's comment at around 1:08:15, and indeed it only refers Hubble's law, not Lemaitre's .. .

Pretty sweet. I get to take in a lecture at MIT and not even pay tuition. I love the internet hug

Correct me if i' m wrong.
Relativity theory, states that an object that travels at very high relative speeds (as light, near light or even faster than light, if it' s possible) becomes relative energy,that for that object point of view all surroundings become relative energy AND his relative motion will be more likely thoroidal for the relative surroundings point of view, and the relative surroundings will be distorted in a thoroidal pattern for the object point of view AND time contracts for the relative object, with contrary effect on the relative surroundings.
Does this statement (if correct) imply that practically, an object surpassing speed light (which seems to be the last thing we can observe in relative movement) simply leaves the bounds of our universe in matter of mass/energy, direction and time? meaning that an object that goes faster than light in a relative way, simply DISAPPEARS from our perception of speed, mass, time? Does it mean that once that object has reached those incredible speeds, it falls into the indetermination realm, from our prospective? Which makes it VERY RARELY interact with our "universe"?
If so, is it possible that randomness of mass, energy, direction, time "direction" and time "lapse" may create infinite possibilities, that randomly affects our universe, coming from infinite others?
Is it possible for that that "dark energy" simply to be matter coming from other universes which RARELY interact with ours, given infinite space and infinite possibilities of universe laws of physics?
It blows my mind, since i was a kid. -
33 views ! wtf? this is of the most superb content on the net!...thanks MIT!...& from a virtually guaranteed future Nobel Laureate mind u.....right up there with Lewin, WSU & Stanford's Leonard Susskind CE lectures.....I rec'n they soulda had "piano kitty" speaking instead...jeez 33?!.....free mind candy 4 all....1 way 2 help fix the future 4 sure !
