According to the Standard Model, the leptons and antileptons should all be separate, independent particles from one another. But the three types of neutrino all mix together, indicating they must […]
The raw ingredients just weren’t there. Thankfully, their predecessors were. Here on Earth, our planet practically overflows with life. After more than 4 billion years, life has spread to practically […]
Binary pulsars are doing what no other measurement has done: measure our galactic acceleration directly. Even though the majority of the matter that makes up our Universe may be completely […]
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 […]
The Younger Dryas impact hypothesis argues that a comet strike caused major changes to climate and human cultures on Earth about 13,000 years ago.
A revolution of the mind must occur in order for humanity to succeed on a finite planet.
The Hubble Space Telescope, 32 years after its launch, broke the all-time record for most distant star. It won’t do better.
Democritus also did not believe in free will but was still known as the “laughing philosopher.”
A new study finds the rocks that first formed Earth carried with them enough hydrogen for three times the water we have today.
Seek pleasure and avoid pain. Why make it more complicated?
How do these little beasties detect light anyway?
Planets can emit radio waves. For the first time, we’ve picked them up from outside the solar system.
Something isn’t adding up, but it isn’t a calibration error. It’s been nearly 100 years since we discovered that the Universe was expanding. Ever since, the scientists who study the […]
A textbook pregnancy consists of three trimesters. The baby develops at a relatively predictable rate during this time, from pomegranate seed to avocado to watermelon. And mom’s body adapts accordingly […]
Researchers find a key clue to the evolution of bony fish and tetrapods.
The Sun will eventually become a red giant star, swallowing Mercury and Venus in the process. But what will happen to Earth? There are a few existential questions we can ask […]
Their goal is a digital model of the Earth that depicts climate change in all of its complexity.
And if you have a friend at the same longitude, you can even measure its circumference. This year’s equinox, on March 19/20 of 2020 (longitude-dependent), is Earth’s earliest in 124 […]
Diogenes was no doubt odd, but Cynicism might just help our overcrowded lives.
Dust sticking to things on the moon is a serious problem researchers are trying to solve.
A Mercury-bound spacecraft’s noisy flyby of our home planet.
A new study explains how a chaotic region just outside a black hole’s event horizon might provide a virtually endless supply of energy.
One look at the uncertainties and the assumptions changes the story tremendously. Is there intelligent life out there in the Milky Way beyond our own Solar System? If so, how […]
Catch Saturn at its biggest and brightest, and view its rings while you still can. Right now, in Earth’s skies, Saturn appears at its biggest and brightest. A view of tonight’s […]
A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.
They’re one of the brightest windows into our Universe’s star-forming past. When we look out at the galaxies in the Universe, almost all of them have supermassive black holes at […]
The strongest tests of curved space are only possible around the lowest-mass black holes of all. One of the most mind-bending concepts about the Universe itself is that gravity isn’t due […]
The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims “parallel Universes,” but is that right?
Even the ones hunting for aliens aren’t excited. Here’s the reason why. In this world, there are very few issues more polarizing than the notion of aliens. For as long as […]
