> The main difference though is that gravitation (probably) doesn't have a mass of its own, while EM fields do. Both gravity and EM fields have energy which is what couples to the gravitational field. Neither of the fields has mass,

Interesting way to phrase the question, the answer is... depends on relative motion. The notion of simultaneity which is the technical term for what you describe as "being flat" in the time-direction is not an absolute thing in re

For "collapse" to occur, the interaction of the quantum system must be with a classical system. A classical system being something big, noisy that can be well approximated by classical mechanics. Simple interaction between two sys

Sorry, I missed that. The time direction does indeed become spacelike inside the black hole. The most remarkable consequence of this is that the singularity is at the future of every test particle that crosses the horizon. This can be seen

Nothing forbids a slight tangential component but the movement of the test particle is inevitably decreasing in r. Closed orbits are impossible though, all test particles finish at the singularity in a finite amount of proper time.

The radial direction of the inside of the Schwarzschild Black Hole is timelike. This means that; inside the event horizon, the inevitable passage of time becomes the inevitable move towards the singularity at the center of the Black Hole. T

The idea of respiratory viruses not being airborne sounds silly. What's the viral charge supposed to do, not jump into droplets smaller than certain size? Of course they are present in the smallest droplets! They are present in the muc

I will bite. This doesn't rule out why it cannot work out. There are some strong assumptions behind this article, it chooses the following scenario: Wind + Solar + H2 for seasonal storage. And then proceeds to dismantle it. But nobody

Haven't read the article yet, so I don't judge the merits of his proposal, but unproven priors is exactly how science is built. A scientific hypothesis is taken without proof, then you derive its consequences and try to falsify th

We don't think so, a very important property of gravity is that it interacts with everything in the exact same way. This property is behind Einstein's Equivalence Principle and in turn on our ability to interpret gravity as curvat

They have but is not taught as science. Physics 101 does not study Aristotles ideas as part of physics. Not because they are wrong but because they are not scientific. They start with Galileo and Newton.

I think you are mixing two different things. Julia is a compiled language and Rust is too. Julia is dynamically typed while Rust is statically typed.

All EM radiation carries energy and the higher the frequency more energy is carried by each photon but that doesn't mean that the energy is transferred as heat (i.e. increase in temperature of the body). The reason why IR is felt as he
