The definitive answer requires better, unbiased data. Despite all the advances that have occurred in human history, one extraordinary puzzle still remains right in our own backyard: we aren’t sure how […]

Enough mass in one location will always create a black hole. But not all masses are possible. If you take enough mass and compress it into a small enough volume […]
The history of the Universe is forever imprinted in our own bodies. We can learn a lot about the history of the Universe just by looking at each of our own […]
When one group says “A” and another group says “B,” consider that everyone might be wrong. One of the biggest enemies of scientific truth is the setup of a false dichotomy. […]
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]
We all share atoms with every person, living or dead, on Earth. There’s more in common among us than you might think. When you eat food, drink liquids, or even breathe […]
This isn’t an XZibit joke; it’s a real scientific question. And the answer may be that it’s possible after all. “People who work every day are kind of scared of things […]
Gravitational waves and electromagnetic ones don’t need to go together. But physics says it’s possible; what do the observations say? “The black holes collide in complete darkness. None of the […]
If you think you can just take a test and demonstrate your scientific literacy, think again. “Through basic science literacy, people can understand the policy choices we need to be making. […]
There’s a lot to learn about other worlds, but you can’t learn it all without looking up. “One should not need a teleportation device to decide whether a newly discovered object […]
Sorry to all you ‘Flash’ fans out there; it’s not reality yet. This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy […]
But that doesn’t mean it actually works as advertised. “All of the books in the world contain no more information than is broadcast as video in a single large American […]
An incredible live-blog of an incredible event. “It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new […]
How does he deliver presents to hundreds of millions of households in just one night? With physics, of course! “Our family was too strange and weird for even Santa Claus to […]
When everything passes away, what will be left? “End? No, the journey doesn’t end here. Death is just another path, one that we all must take. The grey rain-curtain of […]
Is looking for radio transmissions in space like claiming the lack of smoke signals means there are no modern humans? “[W]hat Fermi immediately realized was that the aliens have had […]
If there’s only one Higgs, no unexpected decays and no new fundamental, heavy particles, it might all be over. “There is nothing new to be discovered in physics now. All […]
How the “hierarchy problem,” or why gravity is so much weaker than everything else, might be the key to the entire Universe. “I just think too many nice things have […]
“What was scattered, gathers.What was gathered, blows away.” –Heraclitus When you think of our Solar System, you think of planets (and other object) orbiting our central star, with moons (or […]
At some point, a star’s core runs out of fuel. Then what? “Man loves company — even if it is only that of a small burning candle.”–Georg C. Lichtenberg You normally think […]
Is everything astonishingly simple, though? Or is this a grandiose claim that falls flat when confronted with the evidence? “My main interest is the problem of the singularity. If we […]
Could everything we’ve put together about science turn out to be wrong? “Revolutions are something you see only in retrospect.” –Alan Greenspan We’re always on the lookout for the next […]
Saw “Solar System Questions” by xkcd? Here’s what science thinks it knows. “Put two ships in the open sea, without wind or tide, and, at last, they will come together. […]
It’s the oldest, most distant light we’ve ever seen. But where, exactly, is it? “We are told to let our light shine, and if it does, we won’t need to […]
It has become commonplace to see a "worm" based on the reactions of a tiny sample of audience members running across our screens during televised presidential debates. Psychologists tested whether the worm can influence our voting intentions and the results are worrying in the extreme.
Einstein’s most famous equation works out more neatly than you’d expect. “It followed from the special theory of relativity that mass and energy are both but different manifestations of the […]
The Sun is made almost entirely out of hydrogen and helium; the Earth has hardly any of either. How’d that happen? “The single most powerful element of youth is our […]
The early Universe consisted of atoms, but 99.999999% of them were Hydrogen and Helium. Where’d the rest come from? “A physicist is just an atom’s way of looking at itself.” […]
We’ve learned more about comets than ever before thanks to it. But we would’ve learned a lot more, if not for one unfounded fear. “Every dreamer knows that it is […]
