The laws of physics don’t prefer matter over antimatter. So how can we be certain that distant stars & galaxies aren’t made of antimatter?
It took 9.2 billion years of cosmic evolution before our Sun and Solar System even began to form. Such a small event has led to so much.
Stars are born, live, and die within the spiral arms of galaxies like the Milky Way. These 19 JWST spirals deliver unprecedented riches.
The history of money is a history of convenience, and spending has never been easier than it is today.
Financial illiteracy can become a significant problem. But it’s a problem with a clear solution.
Fear of being scammed can lead us to make decisions that go against our values and goals — both as individuals and as a society.

The engineer working on Google’s AI, called LaMDA, suffers from what we could call Michelangelo Syndrome. Scientists must beware hubris.
Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn’t that violate…something?
Game theory is a unique combination of math and psychology. Its applications turn up everywhere, from nuclear war to Tinder to game shows.

We have pipelines for oil and natural gas. Why not water?
Beautiful people really know how to catch a break.
A clock, designed and built in Europe, ran hopelessly at the wrong rate when brought to America. The physics of gravity explains why.
Most fundamental constants could be a little larger or smaller, and our Universe would still be similar. But not the mass of the electron.
The Universe isn’t just expansion, but the expansion itself is accelerating. So why can’t we feel it in any measurable way?
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
In special relativity, the statement that two events happened at the same time is meaningless.
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
Bears, chimps, or humans? A track of five poorly preserved footsteps at Laetoli has puzzled paleontologists for decades. Now, a research paper from Nature claims to have solved the mystery.
Would you want to live in any of these places?
The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.
