Reply to comment by FlipFlopX in Physicists nail down the most precise value yet of the electron magnetic moment. A newly measured value of an electron’s magnetic moment — a property of its spin and charge — is twice as precise as the one physicists have used for the past 14 years. by MistWeaver80
Thanks for the succinct and illuminating explanation!

Does the more precise measurement resolve or make more puzzling the g-2 (dipole anomaly) announced by Fermilab a few months ago?

Reply to If you could instantaneously place a space telescope at any desired distance (LYs), from any planet/galaxy etc., where would it be and what would you be documenting? And for what purpose? by kennyarsen
I would say our best candidate for a planet with intelligent life. That’s cheating though since we don’t have one (maybe life, but no signs of intelligence yet). The center of the galaxy (outside its black hole) would also be fascinating to pan around what must be a dizzyingly different night sky.
You do have the separate problems of getting any information back home (in a reasonable time at the speed of light) and potentially power (could we ever get a signal from current technology telescopes we place really far away)?

Me too. But how do you break apart something with (near) infinite density whose own gravity nothing can escape from?

If we are in a Big Rip scenario, perhaps once there is no heat differential anywhere, a quantum fluctuation will allow the creation of another universe. Or, perhaps more in the spirit of your post, we are in a black hole from another universe, and that is the end of it all.

I guess I am confused. If you add an arbitrary number of dimensions, are you not adding additional degrees of freedom? And if yes, then is it surprising you can get an infinite number of shapes?
Also, I did not buy the quote, "if it spins too fast, it will break apart". Huh? I'm sure there is mathematical justification for that statement. But physical justification? Everything is within the event horizon. Where would it break apart to without falling back in?
I trust Quanta, generally, as a source. So I am sure their results are valid. Just explained very poorly. (Or so complicated no one can make an analogy for layfolks).

One of the saddest short videos I ever saw (sorry, no link as it was a film theater) was a great white who lost its dorsal fins for soup sliding hopelessly into the dark abyss.
I personally never want to be eaten by an apex predator. Equally appreciate Spielberg’s circumspection with the legacy of Jaws. Which is still one of my favorite movies.

National Geographic (and others) have done whole episodes on this topic.
