Even if you have a problem with the messenger, you still need to heed the message. “Whether humans are responsible for the bulk of climate change is going to be left […]
And if you’re experiencing it consistently, you just might be doing it wrong all along. “I do have a blurred memory of sitting on the stairs and trying over and over […]
If you don’t have pristine, dark skies, you might never connect to the Universe. But there’s hope. “Before we devised artificial lights and atmospheric pollution and modern forms of nocturnal entertainment […]
“The most important, obvious realities are often the ones that are the hardest to see.”
Russian police arrest a robot canvassing humans at a political rally.
For those who still don’t believe in global warming, the science has had it right for half a century now. “Greenhouse gases are the second most important factor for climate, after […]
A new study suggests that sensitivity to the emotion of disgust affects one’s attitudes on immigration.
The Space Aggressor squadrons develop strategies to defend against space-oriented attacks.
Since the March for Science was planned, it’s been mired in controversy from both supporters and those who think it’s politicized.
More massive is bigger, less massive is smaller, right? That’s not even half the story. “Billions of years from now our sun, then a distended red giant star, will have reduced […]
Someday, the Sun will heat up enough to boil our planet’s oceans. Could moving the entire Earth away save us? “I would argue that in any habitable zone that doesn’t boil […]
If the expanding Universe and the cosmic microwave background didn’t convince you, this intricate, spectacular prediction should. “In the current cosmological model, only the three lightest elements were created in […]
Hydrogen is #1, Helium is #2. Who’s number 3? Hint: it’s not #3 in the periodic table! “It is the function of science to discover the existence of a general reign […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
The political and economic ideas of socialism are coming back into fashion.
Drop a chunk of sodium metal into water, and a violent reaction ensues. But it’s more than just chemistry at play. “Chlorine is a deadly poison gas employed on European battlefields […]
We’ve never seen an event horizon, nor directly imaged a black hole. Thanks to a worldwide effort, victory may at last be in sight. “Never look down to test the ground […]
There’s only medicine that works and medicine that does not, writes Paul Offit.
If all we had were hydrogen and helium after the Universe were born, we wouldn’t be here today. “The discovery of deuterium and the marked differences in the physical and chemical […]
If even black holes won’t last forever, what will happen when the last one goes? “My discovery that black holes emit radiation raised serious problems of consistency with the rest of […]
Your bones would “explode.”
You don’t have to detect a particle to know that dark matter is real. “You may hate gravity, but gravity doesn’t care.” –Clayton Christensen In the 1970s, Vera Rubin’s observations showed […]
Why Saturn’s Iapetus has three great mysteries… and we’ve only solved one of them. “The dance between darkness and light will always remain — the stars and the moon will always need the […]
If you heard about time crystals, be aware that they do exist. But learn what they mean. “Every particular in nature, a leaf, a drop, a crystal, a moment of time […]
The Earth is round, Kyrie Irving. But not every world needs to be. “‘I’ll follow him to the ends of the earth,’ she sobbed. Yes, darling. But the earth doesn’t have […]
This AI hates racism, retorts wittily when sexually harassed, dreams of being superintelligent, and finds Siri’s conversational skills to be decidedly below her own.
Why weightlessness is possible, even if there’s no place you can hide from the Universe’s longest-range force. “It was a strange lightness, a drifting feeling. Zero gravity. I understood that […]
If space were really curved due to matter and energy, we should see light deflect. A solar eclipse provides the perfect opportunity. “Eddington had needed to make significant corrections to […]
US scientists fearing for Earth’s climate future begin testing solar geoengineering. The consequences may be terrifying — which is exactly why we need these small-scale experiments.
