Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
In traveling through the expanding Universe, particles slow down while light and gravitational waves redshift. What degrades and what won't?
Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.

Brian Cox examines why, despite billions of stars and trillions of planets, we have found no evidence of other intelligent life.
No civilization, no matter how successful, can last forever. What does the non-detection of intelligent aliens mean for our own longevity?
Throughout history, the ability to tell increasingly believable stories has become available to more people. Kevin Ashton says that’s a blessing and a curse.
The discovery of CDG-2, a galaxy that's more than 99.9% dark matter, could reveal a new population of ultra-faint galaxies. But is it real?

Sam Kean examines how rogue archaeologists are recreating the sounds, tastes, smells, and practices of the ancient past.
When people born blind gain sight, the hardest part isn’t opening their eyes — it’s teaching the brain how to see.

Thanks to modern tech, Earth is now considered a ‘detectable’ planet. Astrophysicist Sara Seager explains how this idea can lead us to discovering life elsewhere in our universe.
No human has ever left the Solar System, and only six already-launched spacecraft will ever exit it. Will Voyager 1 remain the most distant?

"The production of the silicon wafers that are used in the chip manufacturing process requires extraordinary levels of purity."
Quantum entanglement links information between particles across space and time. So what happens when one of them falls into a black hole?
Forget about the terawatt lasers we're making on Earth. The Universe makes natural ones thousands of times more powerful than the Sun.
Even space and time are relative in Einstein's universe. That means our old notions of "where" and "when" no longer apply on cosmic scales.
The idea that it’s “too late” to reduce emissions fuels cynicism and despair, putting us on an even worse trajectory.
There are plenty of engineering obstacles, and those can be overcome. But you cannot change the laws of physics, and those matter too.
The fundamental building blocks of reality are indivisible: quanta that cannot be split or divided. Our understanding remains incomplete.
Long after the last star burns out, the Universe will experience its end state: a heat death. Will everything prior then be meaningless?
Science fiction romanticized Mars as a place of adventure and future settlement; science tells a very different story.
