"The realization - there’s more to the universe than we’re directly aware of - helps us appreciate our place in the cosmos."
Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

"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.

@@degaussingatmosphericcharg575 no that's not true there are many proofs of God, for eg.

If strong nuclear force would've been a bit weaker atomic nuclei would neved had been formed and there are tons of reasons that this beautiful universe is created by someone. Brian Greene is a genius the above man is literally lame, Brian Greene has found mirror symmetry of string theory, and calabi yau maths, and he is also the reason for my motivation in science, but his belief on god is his choice.

Thanks for a great talk. As to the man questioning the veracity of language in describing modern physics: language is a system. All systems are finite by definition. That means that there will be things outside its 'wheelhouse'. I doubt you could describe your favorite painting well enough for me to picture it in my mind anything like you see it. Oh, I might get a feel for colors, composition, & such, and I might even catch some glimpse of what it means to you. But I'd really have to see it for myself; something you'd almost certainly be quick to tell me. But science communicators - especially those who are actually practicing scientists - have not only words, but pictures, as well as math at their own disposal. Plus the fact that as scientists, they've 'seen it for themselves'. They do their best to share all that with us, but it's not easy! There is some truth in saying that areas of modern science - particularly particle physics and cosmology - have become increasingly abstract, and that makes a science communicator's job all the harder. There's also the jargon barrier. All organized institutions have at least a bit of their own language; terms that only apply to their specialty. Parsec is good example from cosmology. The light year that we're familiar with is not something cosmologists often use among themselves. They use the parsec. They also all use metrics; even here in North America (except when NASA forgets!) So there are plenty of challenges to keep an honest science communicator busy! Thanks again. tavi.

@levigoldwing1536 4 жыл бұрын

Any particular energy, particle or otherwise is stripped of it's information . Regarding quantum entanglement, it is believed through the containment of information that the particle is always present in the black hole including it's entangled particle should it be within the Schwarzchild Radius, or Beyond the Event Horizon. Since no energy is known to escape any black holes in our known universe, it is forever encapsulated within the black hole. Moreover, in theory, entangled particles will release energy in the form of Hawking Radiation. Note that energy cannot be created nor destroyed. This is important because it implies that in some form energy absorbed by a black hole should in theory be released. Quantum Physics is more Grey then Black or White. There is more we don't know in the quantum world then anything else. Essential Particles, Quarks and Neutrinos in theory and in experiments violate the Laws of Physics.

Some Scientists have calculated the tensile strength of a single String in respect to String Theory. If you ask that particular Man who have done these calculations to explain how he Imagines Space, Time and Gravitational Effect, because that's what it's all about, I believe you will get a rather unexpected answer, but probably the most close one to the Reality of the Cosmos.

I'm skeptical about his scenario in which 2 people have different times on their watches because they have traveled at different rates. Traveling is only done relative to other objects. If someone travels at the speed of light relative to someone else, the person he is traveling at the speed of light relative to is traveling at the speed of light relative to him. Wouldn't their perception of time be identical?

What keeps planets moving?Gravity only pulls.

@StaticBlaster 3 жыл бұрын

This is explained by Einstein's theory of GR. Gravity does not pull like Newton thought. Rather, the mass of the sun and all objects in space "warps" the space-time "fabric" such that smaller mass objects move around the larger objects. They technically move around the center of mass which is concentrated at the Sun but the sun does kind of wobble due to the other planets' presence. Space pushes mass. Think of it that way instead. So space is pushing on us. That's why we are stuck on Earth's surface. In fact, gravity may not be a force after all. It may be an emergent property of space itself when mass is "warping" it. Also, it may be that gravity is just an illusion. This is a pretty wild speculation but it's a byproduct of black hole physics and what happens to information around the event horizon. If you want more information, look up the holographic principle.

@albertdumont4977 Жыл бұрын

Planets are moving because they are made of stardust that was already moving before they formed the planets themselves. Gravity helped to give them form by accretion. As there was nothing to stop them, they kept moving so far, but not in straight line across the space. The same gravity that gave them shape, keeps the planets moving around the stars. Yes, gravity only pulls, but it doesn't eliminates the initial force given to the planets, otherwise, they all would fall on their own stars of their solar systems. Two forces imbalances each other producing a circular effect.
