Schrodinger's Cat is a hypothetical thought experiment created in 1935 by a man who loved physics and hated cats.

The more closely we observe the present moment, the more amorphous it becomes.

The enigmatic saga of one of astrophysics' most wanted particles.

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.

Quantum bits (aka qubits), the reader is assured, are somehow "entangled" such that they rely on one another. If more detail is needed, we're told entanglement links qubits no matter how far apart they are—so long as the qubits are “coherent.” This hardly helps! So let's try a different approach.

When a theory breaks, you learn how to build it better.

«ASK WEIRD QUESTIONS Einstein had a wild imagination. He asked himself questions like: What would he feel if he rode an elevator through outer space? What would he see if he chased a beam of light?»

You're six miles up, alone and falling without a parachute. Though the odds are long, a small number of people have found themselves in similar situations—and lived to tell the tale.

A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.

New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.

A physicist's task is to constantly create equations that keep up with our observations of physical phenomena.

There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going…

A new experiment pulled off the most precise measurement of an electron’s self-generated magnetic field—and the universe’s subatomic model is at stake.

A concept known as "wave-particle duality" famously applies to light. But it also applies to all matter — including you.

Diffusion models generate incredible images by learning to reverse the process that, among other things, causes ink to spread through water.

A concept called “quantum entanglement” suggests the fabric of the universe is more interconnected than we think. And it also suggests we have the wrong idea about reality.

The real reason that we cannot travel faster than light speed is far more interesting than the textbook answer.

«On the bright side, now that you know about spacetime, the next time your boss gets on your case for just sitting there, you can tell them that they are being unreasonable. You’re moving as fast as possible.»

The quantum world defies our ability to describe it in words. Human experience does not prepare us for its weirdness and uncertainty.

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information, even as the work’s interpretation remains disputed.

The aesthetics of the Atomic Age helped whitewash the threat of nuclear disaster

Interactive article explaining how sound works.

The past and the future are tightly linked in conventional quantum mechanics. Perhaps too tightly. A tweak to the theory could let quantum possibilities increase as space expands.

Is science absolute? Its truths and discoveries guide us towards the nature of reality, but we must always remain open-minded to revisions.
