Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
From a primordial soup of particles, atoms eventually emerged. What happened to make it so, and could things have worked out any other way?
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?
In 1982, an experiment showed unprecedented evidence for exotic matter: magnetic monopoles. But without reproducibility, it didn't hold up.
As the Earth spins and wobbles on its axis and revolves elliptically around the Sun, each day differs from the last. "24 hours" isn't right.
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
Jimmy Doolittle pushed aircraft to their limits and, in the process, helped turn flight testing from daredevilry into a discipline.
The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?
We experience time as real. But what if it's only an illusion: an illusion that's inherently relative? Does time fundamentally even exist?

Doctors told Noa Greenwood's family that she wasn't expected to live past age ten. This new biotech changed that, and opened the doors to a whole new wave of medical funding, treatment, and care.

There's a speed limit to the Universe: the speed of light in a vacuum. But you can beat the speed of light. Just travel through a medium!
Generations ago, cosmologists asserted that the Universe might not just be the same in all directions, but at all times. But is that true?
Today's Milky Way only forms stars slowly. Our galactic center, where the star-forming rate is highest, gives a unique window into our past.
Every proton contains three quarks: two up and one down. But charm quarks, heavier than the proton itself, have been found inside. How?
If you look into a mirror, you'll notice that left-and-right are reversed, but up-and-down is preserved. The reason isn't what you think.
We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!
Big Think’s latest poster is a detailed look at humanity’s loftiest enterprise so far: making it off-planet.
Most of us have heard that the Sun is an ordinary, typical, unremarkable star. But science shows we're actually anything but average.
Our Big Bang could be just one region within an infinite, inflating multiverse. If we were born close to the cosmic edge, what would we see?
