Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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.
There are two rival ideas to try to make sense of the Universe: dark matter or modified gravity. Can a new cosmic test settle the issue?
The newest find recovers the earliest merger in galactic history: just 2 billion years after the Big Bang. Here’s what we know today.
Recent evidence could indicate the Universe doesn't expand evenly. Does that change our expected fate: Big Rip, Big Crunch, or Heat Death?
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
Time isn't the same for everyone, even on Earth. Flying around the world gave Einstein the ultimate test. No one is immune from relativity.
We assume there's no preferred frame of reference in the Universe, and that light behaves the same in all directions. What if we're wrong?
We've now found many "conjoined" objects in the asteroid and Kuiper belts, including the first contact trinary, Nysa. What does it all mean?
