Andrew Strominger: Solving the Puzzle of Black Holes

Harvard University Professor of Physics Andrew Strominger explores the deep theoretical puzzles that have driven black hole research and the insights achieved by recent breakthroughs.

I’ve seen him give this same lecture a few times now. Every time I watch it I’m amazed that he’s able to briefly describe every major topic of modern physics, then within the same lecture describe the edge of humanities understanding of the universe. Without a doubt, he is one of the smartest people on the planet. He understands the equations, the physical implications of the equations, the history of how these phenomena were discovered, and he can elegantly communicate his knowledge in a way the average person can understand.

This is a really wonderful, nuanced little talk on something very complex and not well understood. I really liked it.

Andy Strominger is ALWAYS an interesting lecture or talk

These slides are so much more interesting than Powerpoints. Great presentation! Thank you.

we could all know the long hidden secrets of the universe if only these
scientists would read the utube comments..

The transition of magnetic structures inside heavy atoms under extreme gravity at the black-hole's horizon may make skyrmions with spinning pointing to the center -1. Do this spinning behavior make skyrmions extremely stable and slippery? Please talk about the relation between black hole and skyrmions.

I'm smart enough to know I'm dumb.

There should be an art competition between Andrew and Nima.

Black holes are both QM and classical objects, just like photosynthesis and tunneling, produce food for all plants, or how a robin uses entanglement to navigate while migrating. What is a challenge for physicists is to explain where does the mass reside and how does it spin and as matter falls into it how matter is spit out the poles as jets of particles (and possibly strings) accompanied by magnetic fields. In that, spin, mass and charge are not the only things we find on a BH.
True, the BH inherits 'complexity' and may act as a QC function, involving entanglement, somehow.
Besides the super conducting holographic surface (resulting from circulating charges), where information (energy and hence mass) is stored as strings (hairs), the various magnetic fields can simulate motor action, explaining spin of o.9c.

I recommend 1.5x speed, he's really pleasant at that pace

Is gravity just the absence of empty space? A bit like the Casimir effect, empty space applies some pressure against space that isn't empty, and mass (or energy) takes up space. Does the presence of mass or energy also distort quantum fields (space-time), in a similar way to trying to force a ball into a flexible grid of holes, with the distortion getting less with distance? That would be like minute changes in planck's constant (lower nearer the mass/energy). Planck's constant seems to appear everywhere, so if it changed, would have quite an effect (apart from no longer being a constant).

black hole gm/c^2 = m/10^28 from gravity g, g(p)=g*(m/pm)^2=10^28 strong force in proton strong enough make proton a black hole.

Neutron decay cosmology. Black holes are pressure release valves for universe. Maintaining thermodynamic flow and equilibrium. Conservation. 
The neutrons which invert at moment of neutron star collapse into black hole are transported from highest energy density conditions to lowest energy density points of space, deep voids. There they travel 14ish light minutes before they decay into amorphous atomic hydrogen. This decay process includes a volume increase of 10^14 times. This is expansion. This process is how Lambda is kept in balance. The amorphous atomic hydrogen has no proper orbital electron so cannot emit or absorb photons. This is part of dark matter. From here it follows usual evolution.

Time is a compact dimension one single Planck second long and every point shares this dimension. We exist on one side of hyperplane created by this shared moment of NOW and antimatter is on other side, rotating the other direction over time. This is why baryon asymmetry. This is why chirality. Is this why electron has 1/2 spin? 360 on matter side then 360 on antimatter side? An inflow on this side is an outflow from the other side. Clockwise away here is counterclockwise towards there. This way at every moment the universe requires least energy. Inflow/divergence=negative charge (arbitrary convention notwithstanding) and outflow/convergence=positive charge. This is why the fundamental mass particle is positive charge. Gravity is also a convergence.

Happy Holidays!

Excellent show!

[mayanksoni]

Its been a year where are the predictions

[mikemoss]

However space itself can travel faster than light

[danielroth]

I want to know how something came from nothing.

[alexjointsoon]

why black holes have different sizes if there's nothing inside them? or why they have different masses if they're not made of matter?
