A black hole rimmed with a thin ring of lensed light, faint sparks of radiation rising off its edge above a cratered moon

Do Black Holes Evaporate? Hawking Radiation, th...

In 1974 Stephen Hawking predicted that black holes are not completely black: they should glow faintly and slowly evaporate. The prediction is widely accepted in theory, has never been observed...

Absolute zero is the bottom of the temperature scale, but physics says you can never quite get there. On the way down, matter turns superfluid, expels magnetic fields and piles...

A giant hourglass of glowing golden sand on a cliff at dusk beside a shattered egg, dust blowing away on the wind

Why Does Time Only Go Forward? Entropy and the ...

The basic laws of motion work the same forwards and backwards, yet eggs never unscramble. The answer runs through entropy, probability and the state of the early universe, and part...

A stone tower of alcoves, each holding one cyan and one magenta orb spinning opposite ways, with one extra orb left outside

Why Can’t Two Electrons Share the Same State? T...

No two identical fermions can occupy the same quantum state. That single rule builds the periodic table, keeps matter from collapsing, and holds up dead stars. Here is how it...

A broad blue wave of light rippling through a stone hall and collapsing into one bright point at a dark doorway screen

What Is Quantum Measurement, Really? Collapse, ...

Quantum theory predicts measurement results with extraordinary accuracy, yet physicists still disagree about what a measurement is. Here is what is settled, what is tested, and what remains open.
