Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Agentic AI pioneer Chetan Dube considers ways that everyone can be lifted by the tide of AI, not just those with the capital to leverage it.
Our nearby Ring Nebula, with JWST's eyes, shows evidence for planet formation. Will the Sun eventually destroy, and then replace, the Earth?
The relic signal that first proved the Big Bang has been known and analyzed for 60 years. Join us at the frontiers of modern cosmology!
The CMB has long been considered the Big Bang's "smoking gun" evidence. But after what JWST saw, might it come from early galaxies instead?
In "The Microbiome Master Key," Brett and Jessica Finlay argue that we need to stop waging war on all germs and start working with the microbes that make us who we are.
Once every 12 years, Earth, Jupiter, Uranus, and Neptune all line up, opening a window for a joint mission. Our next chance arrives in 2034.
Over the first half of 2025, the US has cut science as never before. This disaster for American science may be a gift to the rest of the world.
Originally, the abundance of bright, early galaxies shocked astronomers. After 3 years of JWST, we now know what's really going on.
Kathryn Harkup, chemist and author of V Is for Venom, joins Big Think to discuss why Christie isn’t just a brilliant writer but a unique science communicator.
In just its first 10 hours of observations, the Vera Rubin observatory discovered more than 2000 new asteroids. What else will it teach us?
For over 50 years, it’s been the scientifically accepted theory describing the origin of the Universe. It’s time we all learned its truths.
Evolution may have built our brains, but it didn't build them to find truth.
For hundreds of millions of years, a cosmic fog blocked all signs of starlight. At last, JWST found the galaxies that cleared that fog away.
Here in 2025, many of us claim to come to our own conclusions by doing our own research. Here's why we're mostly deluding ourselves.
As the closest icy ocean world to
Earth, Ceres may be a promising candidate in the search for signs of ancient life.
Massive galaxy cluster Abell S1063, 4.5 billion light-years away, bends and distorts the space nearby. Here's what a JWST deep field shows.
Is the Universe's expansion rate 67 km/s/Mpc, 73 km/s/Mpc, or somewhere in between? The Hubble tension is real and not so easy to resolve.
The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims "parallel Universes," but is that right?
Different methods of measuring the Universe's expansion rate yield high-precision, incompatible answers. But is the problem robustly real?
"The rise of the internet brought about similar fears, yet it ultimately made learning richer and more accessible."
