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?
Nurture your passions instead.
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.
All stars shine due to an internal source of energy. Usually, it's nuclear fusion: converting mass into energy. What makes them most bright?
You don't need to be a scientist or a philosopher for facts, reality, and the truth to matter. The alternative is simply known as bullshit.
In this preview from "The Saucerian," author Gabriel Mckee explains how the combination of fantastical stories and obscure bureaucracy launched the “space age of the imagination.”
As we shape our future we should ask: Which interpretations of classic sci-fi fables hold sway with today’s powerful tech leaders?
A Cambridge-based team claims to find molecules on an exoplanet that are only produced by life on Earth. Don't fall for the unfounded hype.
According to Stephen Hawking, spontaneously emitted radiation should cause all black holes to decay. But we've never seen it: not even once.
In all the known Universe, Earth is the only planet known to have native life. What should guide us in expanding humanity beyond our world?
If an asteroid hadn't killed off the dinosaurs, humans would almost certainly have never walked the Earth.
After drastic cuts to the NIH, the FDA, the NSF, and the DOE, NASA science faces down its smallest budget ever. All of society will suffer.
Perhaps no existential question looms larger than that of our ultimate cosmic origins. At long last, science has provided the answers.
From religious iconography to modern mysticism, the human aura has been a subject of fascination across centuries and cultures.
The Hubble Space Telescope, launched in 1990, was originally seen as a colossal mistake. This one image, taken in 1995, changed everything.
Surprisingly, multimodal large language models struggle to read time on analog clocks.
In theory, scientists could've produced a deadly virus that accidentally infected lab workers. In practice, we know that didn't happen.
Planets can create nuclear power on their own, naturally, without any intelligence or technology. Earth already did: 1.7 billion years ago.
The most famous Hubble images show glittering stars and galaxies amidst the black backdrop of space. But more was captured than we realized.
Hugo-winning author Ken Liu explores what early cinema and Chinese poetry can teach us about AI's potential as a new artistic medium.
