[@numbers9696]

He based it on the equivalence principle and used it to make the argument that gravity bends light. He used a mathematical object named tensors, to represent the fact that the laws of physics don’t change, no matter where you’re standing or how fast you’re moving(reference frame) After he realized that space and time are curved he used the geometry of curved surfaces, called Riemannian geometry. Then built the energy momentum tensor using mass, energy, momentum, pressure and even heat. Derived his field equations which relate the curvature of spacetime to the energy momentum tensor. Used it to predict mercurys orbit. Physics sexually excites me

Kudos to Brian for making the Information paradox a digestible topic!

[@swap709]

A better way to describe the end of time is that you and your surroundings become infinitely slow as compared to what’s outside the event horizon (the rest of the universe). So a few billion years could pass by in the universe within a second for you in the event horizon. If the universe exists for a finite time, then you would reach the end of time very quickly

Finally some new brian cox lessons

[@markkirby9531]

OK, as someone who has a degree in physics, let me try to provide some additional info. It is a fundamental aspect of particle physics that "particle/anti-particle" creation takes place. This can be thought of as a combination of the Heisenberg Uncertainty Principle - the energy/time portion specifically. ΔE * Δt ≥ h/4π, where ΔE is the uncertainty in energy, Δt is the uncertainty in time, and h is Planck's constant. The simplest analogy to explain this is that there is a cosmic accountant, who monitors the amount of energy in a particular location. Someone wants to "steal" energy from the "company" and if one steals a small amount, it will take some time for the accountants to notice. If one steals a large amount, they'll notice it much sooner. So, this means that there is energy that can be "stolen" to be used from some other purpose. Now, if one couples this with Einstein's E = mc^2, this means that one can consider energy as "frozen matter" and this "stealing" of energy can be used to create matter. Now, to comply with other conservation laws ( electric charge, momentum, etc.) there are constraints on the particles that can be created from this "stolen" energy. In general, it is limited to the production of particle/anti-particle pairs. One such example is an electron and a positron. Or other wise known as matter and anti-matter. They will come into existence, survive for a short period, then collide and annihilate themselves, returning the energy used to create them in the first place. As long as these particles exist before the "auditor" returns, all is OK under Heisenberg. As such, they are often called "virtual particles". What Hawking asked is what happens if such a pair of particles is created just outside the event horizon of a black hole. The gravitational field of the black hole is the energy source used to create the virtual particles. He realized there were three possible scenarios. 1) Both virtual particles fall inside the event horizon and so are gone from the universe. 2) Both virtual particles remain outside the event horizon and annihilate each other as any other virtual particle pair. 3) One falls inside the event horizon and one does not. Oh boy, #3 is a big one. It means that the virtual particle that remains outside the even horizon no longer has an opposite to annihilate with and so transitions to a "real" particle. This particle is what makes up the "Hawking Radiation". In addition, it has reduced the mass of the black hole by it's mass. As this process continues, the mass of the black hole would be reduced by the Hawking Radiation, until it "evaporates".

The accretion disk is not flat for the M87 and SgrA* black holes. They are actually thick, and because they are not thin disks, they are referred to as accretion flows.

[@taxt17]

One thing to keep in mind. The reason why it is the end of 'time' is because Spacetime are one thing essentially. We can imagine space being warped into infinity but time as well.

[@HankMeyer]

I don't understand how we know we're not inside of a black hole right now. The way he describes the interior of a black hole sounds to me like a description of the observable universe. I mean we're moving inescapably to the end of time right now. Plus space appears to be expanding at an accelerating rate, as though it were falling in all directions, toward the end of time. Also, I've heard that a black hole with the mass of the observable universe would have an event horizon that is about the same size as the observable universe. To me that sounds like mathematical proof. A region of space that has the observable universe's mass would form an event horizon and therefore be a black hole, if it was contained within a volume of space the size of the observable universe, which it does and is.

We are constantly falling into a black hole and that is why time only flows forward but mathematically it should also go backwards.

[@GrammyPhantom]

It’s almost like he’s explaining the inverse of the big bang. So my question is, was our big bang the only singularity in space? Or was it just a cycle of a previous black hole. Maybe it’s just an infinite loop of beginning time and ending time. And blackholes are the center of time starting and time finishing.. shit idk im high af

My first thoughts as well. Difficult to imagine that beings only a blink of an eye further than dealing with sticks and rocks would be able to measure stuff that confirms or denies such theories, isn't it.

[@KarmaKahn]

I am surprised he did not mention the holographic principle by Leonard Susskind, who disagreed with Hawking. Also, a black hole grows when matter falls into it. So, not sure how that can be explained as a loss of information. Also, over eons and eons a black hole will eventually evaporate away. So, nothing really disappears.
