Lab-grown [sort of] black hole behaves just like Stephen Hawking said it would

James Clerk Maxwell was a scientist that used analogies to approach problems he didn’t understand using similar behavior in things he did. He explained magnetic and electric flow using the mathematics of fluid flows and he was right even though they had no idea what was actually “flowing” (electrons).

In this case the analogy is interesting but not really that informative. The problem is they are using the behavior of actual atoms (real) to explain the proposed behavior of virtual particles at the boundary of a black hole (not real). Quantum field scientists understand that virtual particles are fictions used in Feynman diagrams to make the math easier and don’t exist. Hawking understood this as well and the idea that virtual particles would “fall into” a black hole would make him laugh. Hawking radiation is a function of entanglement entropy at the boundary of a region of space and not some fairy tale of virtual particle splitting.

Wake me up when they actually find dark matter.

Create Oobleck And Make It Dance To The Music Named after a sticky substance in a children’s book by Dr Seuss, Oobleck is a non-Newtonian fluid, which means it can behave as both a solid and a liquid. And when placed on a sound source, the vibrations causes the mixture to gloopily dance.

This passes as science today?

Your perspective is ‘heavysided’. Maxwell’s equations were brilliant insights.

Cool... This one’s all sciency and stuff.

Once they can establish a method to replicate the experiment and outcome, they will be looking for more Biden votes....bet on it!!

Since when do they need real Biden votes to pull off a win? Hmmmm?

[Dat]

It does, but not all math is physics.
