Black holes aren't black. Hawking radiation makes them slowly evaporate — and the resulting information paradox is rewriting modern physics.

What string theory really proposes, the extra dimensions, M-theory, the multiverse landscape, and why critics call it unfalsifiable in 2026.

A wormhole — a shortcut through spacetime connecting two distant points — would revolutionize physics, transportation, and our place in the universe. But the physics suggests it would also be unstable, possibly lethal, and almost certainly a one-way trip.

General relativity describes gravity at cosmic scales. Quantum mechanics rules the subatomic world. They are mutually incompatible — and unifying them is the deepest unsolved problem in all of physics.
