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.

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

Is spacetime the fabric of the cosmos ?. Mass tells spacetime how to curve , and , curved spacetime tells mass how to move .

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?”

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.

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.
@venkatbabu186
@venkatbabu186 5 лет назад
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.
@venkatbabu186
@venkatbabu186 5 лет назад
E power phi i equals minus one. It is just substitution of half and mass zero. So that also works.

If you put gravitational constant as Y then f equals G m1 m2 over r squared also works.
