- The laws of physics can’t account for any particular direction in which the universe develops. Therefore “time’s arrow” must somehow be a relic of the conditions at the moment of the big bang.

Three minutes in the lecture and I’m already there where only Brian can take me ❤
Brian Greene...top lecturer of our time. Explains complex topics with analogies that really give things life.
"Science without religion is lame, religion without science is blind". - Albert Einstein
Brian Greene is a clueless atheist and a poor scientist. He ignores a great deal of evidence of GOD and has hit a wall in string theory that only GOD=7_4 can penetrate. See GOD704.fandom.com .
What has Greene discovered? Nothing. His science is lame.

That Brad Wilson seems to be leaving comments on all these Brian Greene talks, but I can't see any of them.

@@ansfridaeyowulfsdottir8095 His mom caught him.
I liked "Small writing on a balloon", (becoming temperature differences in the cmb) ,being compared to the original Quantum jitters becoming measurable after the Big Bang .
The man is a genius at explaining complex science to non scientists.
This is wonderful! I Soo respect the way he helps us to understand what he loves and has hopes that we will come to understand the universe we have come to live in and be apart..and even more the way he Nevers disses anyone for their faith,knowalge,view point HE LIVES TO TEACH and I so totally respect ! wish there were more people like this so we could all have that in life
"The fabric of the cosmos" ...I have read this book.....and he is the magician. He defines all the stuffs so elegantly....
I had watched his videos on TH-cam ....Light falls is the fabulous debate....and...the daily equations is extremely important and idyllic
Is spacetime the fabric of the cosmos ?. Mass tells spacetime how to curve , and , curved spacetime tells mass how to move .
This deserves a lot more views.
Brian is the true MVP
very nice explanation!
Thanks. Professor Greene is always interesting & informative. @31:30 - How about calling it 'the most important *_heads up_* in cosmology'? tavi.
Love Brian Greene. The obvious question that popped into my head was this: If the universe isn’t expanding into anything, then how can there possibly be more than one universe? In his answer to one questioner he said “the universe isn’t expanding into anything. It just creates space within itself as it expands.” And in another response he said that two universes could potentially expand into each other. How can you measure the distance between two universes that are expanding into nothing, and therefore separated by some distance of “nothing?”
Thank you...
What I would like to know is how exactly does the curvature of space-time creates the tides, stabilizes the Earth axis, and influences the lives of so many living beings?
Can you see inside of a radio wave
Like a string theory. Thoughts
Very enjoyable inspite of the poor video quality. The sound was spot on. Thanks..
you might want to modulate the pitch of your voice dietrick
I have a hypothesis. A lot of lectures and intellectuals try to talk to the general public, I think the have 1 of 2 issues or a combination of both. 1 they were bullied and tormented while they were young possibly even in being a young adult, The other is success. They have been so successful they have become condescending and arrogant. When this happens they consciously or unconsciously use too many complicated terms and make the subject too complicated for the general public to grasp and understand. This strokes their ego. "They are much more intelligent then the general public." Brian Greene, Noel D'grasse Tyson, Sean Carroll, Brian Cox these men stood up for themselves they connected with other people that were in other fields. So they can convey these super complicated subjects to everyone and for everyone to understand and enjoy. Just my hypothesis.
Doesn't begin until well after 8:00 minutes because we have to hear two old white dudes trying to out-monologue each other to introduce Brian Greene.
What class you have...
No place for this BS. F*** off.
*_"Doesn't begin until well after _**_8:00_**_ minutes"_*
Thanks for that. I hate these Tiresome, Interminable Introductions of Tedium.

" the laws break down" maybe the laws were not produced yet so of course anything we learn of do cant find things that didn't exist yet . cosmological thought before action
Close to log 16
sir, indian theroist phsyic people are top notch
When you have to teach mathematics and physics you have to teach them beautiful. Somewhat like. Say you have water in a tank and slightly tap on the surface of water what happens. You see a ring kind of formation and you see a wave kind of patterns go through. That wave kind of pattern is called a sin wave. Sin X means that kind of pattern representation using mathematics. Where X is the angle. Now assuming a perfect surface with no other force this pattern will go on forever. In case of mathematics you have theta as the angle but in physics we call it as time and the amplitude or the bulge the displacement or distance. There are two kinds of distance one is vertical and the other is horizontal with respect to time. There are two times evolved one is distance of the amplitude from a particular point and the other time is the forefront of peaks from the centre. So when you create ripples or patterns you have two kinds of time and distance. So normally the universe keep expanding for ever. The time from the centre to the displacement time is called relative time. And the other relative distance. So when you tap one is a sin wave and the other a imaginary wave. So sin X + i cos Y = 0. Similarly from the edge it is cos X + i sin Y = 0. Say if you were to hit the surface a bit faster then water splash and then fall back as drops creating other ripples and they travel for ever creating other ripples. This can be represented as sin X + i ( sin Y + i cos Z) = 0. Note three distance and three time. The second equation is sin X + i ( cos Y + i sin Z) = 0. The third cos X + i ( sin Y + i cos Z) = 0. Z represent mass Y represent space and X represent velocity or spin. The cubic equations so formed are called the ripples on the fabric of space time.
The only proof left out is three dimensions are enough to represent all other dimensions. Mathematics has to prove that.
Say you want to derive sin square X plus cos square y equals one. Z is zero so no mass. Substitution z as zero gives the formula of pythogorus theorem.
E power phi i equals minus one. It is just substitution of half and mass zero. So that also works.
Sum to infinity of numbers is minus one twelves also work.
If you put gravitational constant as Y then f equals G m1 m2 over r squared also works.
"In a minute they will." Ah HaHa. 😄.
Parallel society
his cousin talked bout it in building and plots
The initial speaker reminded me of Dr. Strangelove.
More stuff is cooling down to do with more space yet space catches up
To the getting down cosmological
Spin catches back up ripping up time
By ripping up some space memories
Some of gods conscious
Particles reversing memory
Of time . i tried 😃

To bypass the TWO Tiresome Introductions of Interminable Tedium.
You're Welcome.

Beautiful cool down hand on head I don't like to sweat
Jesus calm down bro
I wish he'd stop calling it "Striing Theory". It's not a theory at all, it's a very highly theoretical hypothesis. There's a BIG difference.
{:o:O:}
Semantics .
You feeling ok ? Maybe you need to bring this to the attention of your shrink ....
First
The god can be anywhere!
Briian looked in a bad mood in this lecture QA, he didn't look at ease at all. 😢😢
