Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.

Timeline of the universe from the Big Bang, as described in cosmology, showing inflation, formation of atoms, stars, galaxies, and expansion to the present day over 13.8 billion years.
If you want to understand the Universe, cosmologically, you just can't do it without the Friedmann equation. With it, the cosmos is yours.

If happiness is an absolute good, would 1 billion slightly happy people be better than 1 million incredibly happy people?
A blue planet with visible rings and several small, bright Uranus moons is set against a darkened black background.
Viewing Uranus's largest moons with Hubble, astronomers hoped to find darkening on the trailing side. They found the exact opposite instead.
A worker in protective gear operates machinery in an industrial facility, with a partial overlay of solar panels and geometric patterns above—hinting at the innovative spirit found in stellar societies.
The cofounders of think tank RethinkX are convinced that humanity is undergoing civilizational phase change.
A white dinosaur skull silhouette on a black background with red, rough, scribbled lines evokes the intrigue of the dinosaur myth.
In "The Shortest History of the Dinosaurs," Riley Black reveals the bold mammals that thrived in the Age of Reptiles.
An illustration shows a cosmic ray entering Earth’s atmosphere, creating a cascade of secondary particles—some of the highest energy particles astronomers study—detected by an array of sensors on the ground.
On Earth, our particle accelerators can reach tera-electron-volt (TeV) energies. Particles from space are thousands of times as energetic.
Image of two large elliptical galaxies surrounded by several smaller, colorful galaxies and stars against a dark background in space.
The first galaxies were irregular blobs of gas and stars. But modern features, like spiral arms and bars, appeared earlier than expected.
