Is There a Theory of Everything, and What Would...
Physics has a tested theory for three forces and a separate one for gravity, but no accepted theory joining them. The graviton, gravity’s hypothetical carrier particle, has never been seen....

What Is Spaghettification? Tidal Forces Near a ...
Spaghettification is the stretching of an object by tidal forces: gravity pulls harder on the near end than the far end. Near a stellar-mass black hole it would tear a...

Why Do Muons Reach the Ground? Time Dilation, M...
A muon at rest lives about 2.2 microseconds, enough to travel only a few hundred metres even at nearly light speed. Yet muons made high in the atmosphere are counted...

Stephen Hawking: What Did He Predict, and What ...
Hawking’s 1974 prediction that black holes radiate is central theoretical physics — and still unobserved in astrophysical black holes. Analogue experiments are not detections. The information paradox is open. Penrose’s...

How Does Gravity Bend Light? Einstein Rings and...
Gravity bends light because spacetime is curved. The 1919 eclipse measured the Sun’s deflection; Einstein’s 1936 note foresaw stellar lenses; modern telescopes image Einstein rings. Here is the physics without...

If black holes evaporate into featureless heat, what happens to everything that fell in? Here is Hawking’s paradox, the Page curve that turned it into a calculation, the recent “island”...
