The Michelson-Morley experiment of 1887, despite expectations, revealed a null result: no effect. The implications were revolutionary.

All telescopes are fundamentally limited in what they can see. JWST reveals more distant galaxies than Hubble, but still can’t see them all.
Recent research sheds light on how the brain overgeneralizes fear, causing people to be afraid of harmless situations.
Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.
The sharpest optical images, for now, come from the Hubble Space Telescope. A ground-based technique can make images over 100 times sharper.
Some processes, like quantum tunneling, have been shown to occur instantaneously. But the ultimate cosmic speed limit remains unavoidable.
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
For centuries, Newton’s inverse square law of gravity worked beautifully, but no one knew why. Here’s how Einstein finally explained it.
There’s a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
In a distant galaxy, a cosmic dance between two supermassive black holes emits periodic flashes of light.
How the simple act of watching twilight can radically transform our perception of the world and our role within it.
Light carries with it the secrets of reality in ways we cannot completely understand.
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
The first-of-its-kind approval could change how we think about gene-edited foods.
Nothing can escape from a black hole. So where do Hawking radiation, relativistic jets, and X-ray emissions around black holes come from?
In 1054, a core-collapse supernova occurred 6500 light-years away. In 2023, JWST imaged the remnant, and might solve a massive mystery.
Lasers, mirrors, and computational advances can all work together to push ground-based astronomy past the limits of our atmosphere.
You are trapped in time. You never live in the world as it is but only as you experience it as it was.
A concept known as “wave-particle duality” famously applies to light. But it also applies to all matter — including you.
For its 2-year science anniversary, JWST has revealed unprecedented details in “the Penguin and the Egg.” Here are the surprises inside.
All human development, from large cities to small towns, shines light into the night sky.
If you think of the Big Bang as an explosion, we can trace it back to a single point-of-origin. But what if it happened everywhere at once?
Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?
In logic, ‘reductio ad absurdum’ shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.
Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.
Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.
Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023’s Nobel Prize.
What do ghosts and anomalous galaxy rotation rates have in common? Some sci-fi enthusiasts believe the answer involves “parallel universes.”
There’s a speed limit to the Universe: the speed of light in a vacuum. Want to beat the speed of light? Try going through a medium!
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
