In war-torn areas, females tend to seek the protection of males with the warrior gene, leading to self-sustaining wars. Any ideas how to counteract?

A warrior gene complex has been identified (James Fallon et al.), and a current theory says that females in conflict areas tend to naturally seek the protection of males who exhibit that gene...

Has it suddenly become fashionable to state that 'There are no Black Holes', further to Stephen Hawking's recent paper altering their definition?

For those who take that view - can you then please walk us through what happens in the wake of a massive supernova burst ? All the scenarios I see lead back to a black hole, and I'd be really...

Some proponents of the metaverse say that a multiverse necessarily contains an infinity of identical copies of yourself

Along with an infinity of near-identical copies, etc. ad infinitum (Colin Bruce, Tegmark, et al.) In a nutshell, this affirmation is based on the fact that a non-zero probability (you exist, so...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
