Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
In 1982, an experiment showed unprecedented evidence for exotic matter: magnetic monopoles. But without reproducibility, it didn't hold up.
Until recently, nobody had visualized the fungal "Wood Wide Web."
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?
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?
In 2025, two cleverly designed studies claimed to find evidence of strange objects orbiting Earth — years before humanity had put anything in space.
"Publish or perish" has become an academic cliché. But the biggest casualty isn't researchers — it's scientific discovery itself.

The double-slit experiment, hundreds of years after it was first performed, still holds the key mystery at the heart of quantum physics.
The sky and oceans are both blue. It's not because one reflects the other. Science explains them both, but for very different reasons.
