Thanks for the post. Now I can tell what a gangster fraud Richard Feynman was. If it weren't so mk-ultra serious, RF would be a clown. Telling more Babylonian slave culture fairy tales. ---- from RF's wiki Feynman played an important role on the Presidential Rogers Commission, which investigated the 1986 Space Shuttle Challenger disaster. He had been reluctant to participate, but was persuaded by advice from his wife.[182] Feynman clashed several times with commission chairman William P. Rogers. During a break in one hearing, Rogers told commission member Neil Armstrong, "Feynman is becoming a pain in the ass."[183] During a televised hearing, Feynman demonstrated that the material used in the shuttle's O-rings became less resilient in cold weather by compressing a sample of the material in a clamp and immersing it in ice-cold water.[184] The commission ultimately determined that the disaster was caused by the primary O-ring not properly sealing in unusually cold weather at Cape Canaveral.[185]

Are you kidding? We've got rudimentary quantum computing, measured gravity waves, detected the Higgs particle, observed galaxies formed just after the big bang, detected supermassive black holes at the center of nearly every galaxy we looked at, and made many more observations that tell us we don't know nearly as much as we thought we did about gravity on the galactic scale (and larger) or cosmology in general. A lot of theoretical work has been done in quantum physics (e.g., superstring and M-theory), but I don't think anything except quantum chromodynamics has really stuck since QED. But there's only one fundamental mystery left in quantum theory - gravity, right?

Feynmann was working at Caltech at the time and was yet to receive his Nobel Prize; this would be awarded the following year.

Because the earth is not hollow. compared as you going deep in a pool and the hidrostatic pressure hurt your ears, the crust the mantle and all the layers are atracted to the center, and the pressure closest to the center increases. It is just the weight of the different layers. And although g is actually zero on the exact centre of the earth it increases acordinf to the mass, the density of the layers and the inverse square law as you go to the surface

@@sonarbangla8711 A singularity would be if g was a negative number. if there was a hollow "ball" with the same mass of the earth and same diameter, the gravity it would pull would still be the same, the center would stil have g=0 but there would be no pressure on the way down, thats what I meant. The earths centre has no g because it is just a point. however, it has mass. every centimeter away from that point is atracted to that mass by newtons law and increases up to the g on the surface. The same happens on the moon (since the distance and mass are smaller the g on the surface is smaller) and on any rocky planet, for sure. dont know about the gas plates but the same principle would apply.

@@sonarbangla8711 An object at the center of the earth is experiencing gravity from the entire planet, only that gravity is pulling outward from the object with nearly equal force in every direction because that's where the planet's mass is. In this case, g ~0 because it represents the sum of gravity in all directions. That outward pull would of course be resisted by the extraordinary pressure. To understand the pressure, consider that the gravitational force on an object at the center is not only pulling that object outward in all directions (a 3D stretching), but the object at the center is also pulling the planet onto itself, and so are all of the objects within the area. The sum of that gravitational attraction toward the inside of the planet (toward the barycenter) is where the huge pressure comes from. The formula: Did you mean p = ρgh? That is for pressure resulting from a column of fluid. (I think mgh is potential energy.) The variables are for the column above you - its density, its gravitational acceleration (toward the center, if it could fall), and its total height, none of which are zero.

Tyson is a great explainer, but that's his main focus. He meets people where they're at. He doesn't sit at the university or planetarium waiting for people to come to him. Feynman was a brilliant physicist. He pushed the frontiers like few others have. He made sense out of quantum electrodynamics, along with being a co-discoverer. He was also a brilliant explainer, but he didn't do the kind of public outreach that Neil dGT does. His public talks were amazing though. Physicists today work in huge collaborations. Any discovery that might have some meaning will be published in a paper with 30+ authors, not one rock star. (The paper announcing the discovery of the Higgs boson had over 5,000 authors!) We've got brilliant scientists today doing brilliant science, but they tend to focus more on the science than the personalities, with the exception of those who have made a career of communicating with the public, which I think is also a noble calling in science. (Sean Carroll is my favorite science communicator today. If I can follow one of his talks, I feel like I've earned another degree! 🙂 Of course Sagan was the GOAT.)

We have never understood gravity, and now we realize we're farther away than ever from that understanding. Is it surprising that the one scientific near-miracle you would like to see hasn't yet been performed? Science is thriving! We just have a lot more work than we previously thought. We need to deal with this dark energy thing...

That logic promotes paranoid ignorance and book sales, not scientific advancement. Spacetime is the set of the four known dimensions. The order in which you list them (time-space) does not alter the composition of the set, nor does time hold any special significance among the four. It's not like a mathematical reciprocal (unless you reverse the direction through which you're observing time). When a consensus of scientists rejects a theory, there's nearly always a good reason for it.

Gravity, just got the idea of what it is. Surplus electrons or their absence. What is the net charge of a planet as opposed to a newton star with its degenerate electrons that help support it against collapse? Gravity is proportional to mass but something is wrong. Think of a dielectric effect that mass has on the electric permittivity of free space. Gravity is weak but it could still be a just a weakened electrostatic or dynamic force. There are examples of sub atomic particles where laws of attraction are not 1/R^2. Feynman said something and I immediately agreed and started typing this. To conclude, mass is not the cause of gravity even though its true that its a straight linear relations ship. It's the residue of electric and magnetic fields of each object causing the attraction. The spooky forces of attraction are what make physics so hard to comprehend as Dr. Feynman has noted. Observation with cause and effect are not usually truth about why it is the way it is. It's like mass is the dark area of the Mandelbrot set, an infinite set of points completely is disconnected from the other infinite domain of points in color. We have photons and kilograms. One collects spontaneously, the other is doing its best to never rest for a nanosecond at least until it get's too close to a nucleus, neutron star or black hole. Is it not rational to think that if energy wants to scatter then mass will respond by collecting. It's a balance between potential and Kinetic energy's.
