Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would “ER = EPR” mean for our Universe?
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
Hubble showed us what our modern day Universe looks like. JWST’s big goal was to teach us how the Universe grew up. Here’s where we are now.
In a citizen science project, thousands of pet dogs are helping scientists to understand what happens to memory and cognition in old age.
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST’s eyes, astronomers found so much more.
It’s that time of year when the hours of meticulous wrapping of Christmas toys are viciously undone in seconds by tiny children.
The most momentous and significant events in our lives are the ones we do not see coming. Life is defined by the unforeseen.
As the American population grows, fewer people will die of cancer.
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
Temporal lobe epilepsy seems to rewire a part of the brain that’s key to storing memories.
The game of Plinko perfectly illustrates chaos theory. Even with indistinguishable initial conditions, the outcome is always uncertain.
Hunter-gatherers probably had more spare time than you.
From up close, the cracking sound of a thunderclap dominates. From far away, it’s more like a drawn-out rumble. Can science explain why?
Despite their brief history, computers and AI have fundamentally changed what we see, what we know, and what we do.
Science was never the same after meeting ‘the particle who lived.’ Back in the early 1930s, there were only a few known fundamental particles that made up the Universe. If you […]
If we waited long enough, would even protons themselves decay? There are certain things in the Universe that, if you leave them alone for long enough, they’ll eventually decay away. […]
Argentina’s black market for cash is embracing crypto — but it’s not what crypto proponents expected.
If stars don’t go supernova at first, they can get a second chance after becoming a white dwarf. But can their companions survive?
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.
The Taupo volcano was responsible for one of the most violent eruptions on record.
After 100 million nights of people asking, “What are those twinkly lights?” it is pretty remarkable that we happen to live in one of the first generations that actually knows the answer.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
Although equal parts Hollywood blockbuster and Putinist propaganda, “Trotsky” still manages to capture the good, the bad, and the ugly of Russia’s revolutionary past.
Back in 1990, we hadn’t discovered a single planet outside of our Solar System. Here are 10 facts that would’ve surprised every astronomer.
Anything, good or bad, about Henry Ford can be contradicted — except his ambition and his work.
Some question the ethics of sanctions aimed at cancelling Russian art and culture and punishing ordinary citizens.
Today, we could use Big Data to radically reform democracy. Tomorrow, we could build nanofabricators and usher in an era of abundance. Is society ready?
