Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Many, from neuroscientists to philosophers to anesthesiologists, have claimed to understand consciousness. Do physicists? Does anyone?
With stars, gas, and dark matter, galaxies come in a great array of sizes. This new one, Ursa Major III/UNIONS 1, is the smallest by far.
NASA astrophysics, which gave us Hubble, JWST, and so much more, faces its greatest budget cut in history. All future missions are at risk.
Just 10 years ago, humanity had never directly detected a single gravitational wave. We're closing in on 300 now, with so much more to come!
The fact that our Universe's expansion is accelerating implies that dark energy exists. But could it be even weirder than we've imagined?
The laws of physics obey certain symmetries and defy others. It's theoretically tempting to add new ones, but reality doesn't agree.
The award-winning nature writer, Robert Macfarlane, talks with Big Think about how to reacquaint ourselves with the rivers in our lives.
For centuries, vaccines have been the top life-saving, expert medical intervention known to humans. How can individuals make the right call?
It took nearly 400,000 years, after the Big Bang, to first form neutral atoms. The imprints from that early time can now be seen everywhere.
The COSMOS-Web survey is now complete, combining JWST and Hubble infrared data. Its spectacular views show us the Universe as never before.
Since 1998, we've known our Universe isn't just expanding, but the expansion is accelerating. Could the Big Bang itself be the reason why?
For millennia, diamonds were the hardest known material, but they only rank at #7 on the current list. Can you guess which material is #1?
As democracy recedes and fascism rises in the USA and around the world in 2025, history provides a lesson in how science can fight fascism.
Will platforms continue to offer the like button as an all-purpose tool — or will each of the button’s various functions exist in new forms?
The laws of nature are almost perfectly symmetric between matter and antimatter, and yet our Universe is made ~100% of matter only. But why?
There are limits to where physics makes meaningful predictions: beyond the Planck length, time, or energy. Here's why we can't go further.

"It's a true fact, but a bizarre one, that the reason why hundreds of thousands of people died in Hiroshima and Nagasaki rather than Kyoto and Kokura, is because of a 19-year-old vacation and a passing cloud."
