The greatest danger to our planet is not pollution or climate change, but our own despair.
But we shouldn’t give up on direct detection. Here’s why. Dark matter is not only the most abundant form of matter in the Universe, it’s also the most mysterious. Whereas all […]
Butter supply and life satisfaction are linked — but by causation or correlation?
The new fossil offers insight into when whales returned to the oceans millions of years ago.
It’s a record magnetic field, but… yeah. That didn’t last long.
A universal basic income is just one of Andrew Yang’s ideas to update capitalism for the 21st century.
Stars don’t stay the same throughout their life, and the Sun is no exception. Here’s what’s going on. Here on Earth, the ingredients for life to survive, thrive, evolve, and sustain […]
White dwarfs, neutron stars, and brown dwarfs aren’t actually stars at all. Here’s why. When it comes to stars, there’s a huge variety of different types out there. Our Sun is […]
If we find the earliest signal from the Universe’s birth, how can we be sure we aren’t fooling ourselves? When it comes to the origin of the Universe, the Big […]
If this discovery came in a pre-LIGO era, maybe it would have been a surprise. But in 2019, there’s no mystery at all. Did you hear that astronomers had recently […]
“In so far as bodily movements build the brain, every movement a human makes matters.”
NASA research finds a new direction in searching for signs of life in the Universe.
Carl Sagan—who first coined the term—was tempted to call them “star-tar.”
They didn’t know it, but the rituals of Iron Age Scandinavians turned their iron into steel.
At ground zero, Trinitite, the green, glassy substance found in the area, is still radioactive and must not be picked up. The Trinity Site was where the first atomic bomb […]
Scientific discovery often happens when you least expect it. But no one could’ve expected this. Imagine that you’re a scientist, going out on a limb to design and build an experiment […]
It’s the ultimate way to go… and yet, it still isn’t what you’d expect. There are many terrifying ways that the Universe can destroy something. In space, if you tried to […]
The Universe was born matter-antimatter symmetric. Here’s what happened when the last of our antimatter disappeared. Things happen fast in the earliest stages of the Universe. In the first 25 […]
Our biases, preferences, and ideas of simplicity and elegance can get in the way. Here’s a scientific way to cut through them all. What are the rules governing reality? If you […]
Having ‘high levels of intelligence’ is no excuse for rejecting quality scientific information. You think of yourself as a generally intelligent person, don’t you? Someone who’s good at deducing fact […]
If the only advice you’ve heard on public speaking is to imagine the audience in their underwear, this article’s for you.
Shortly after the Big Bang, the Universe became completely dark. The first stars, when they ignited, changed everything. For perhaps 100 million years, the Universe was devoid of stars. The […]
It took hundreds of thousands of years to make atoms for the first time. If things were just a little different, it could have taken an eternity. When it comes […]
And do they fundamentally describe our entire Universe, or do we require something else? The Universe we perceive and view, all around us, isn’t representative of what actually exists at […]
Over two billion people regularly eat insects. Why are Americans so squeamish?
A single thought experiment reveals a paradox. Could quantum gravity be the solution? Sometimes, if you want to understand how nature truly works, you need to break things down to […]
Now is a good time to brush up on who’s on the ballot.
Our outer Solar System, from Jupiter to Neptune, isn’t unique after all. In the early 1990s, scientists began detecting the first planets orbiting stars other than the Sun: exoplanets. The easiest […]
