There are three things your new theory must do in order to be taken seriously as science. This one’s 0-for-3. Every once in a while, a revolutionary idea comes along that […]
Ever wondered why the longest day of the year happens when it does?
We don’t perceive time in an objective fashion; instead, the brain interprets time in a complex and amorphous way.
Our future fate is likely already determined. If we end in a Big Crunch, what does that mean? The ultimate fate of the Universe is one of the biggest existential questions […]
While the web of dark matter (purple) might seem to determine cosmic structure formation on its own, the feedback from normal matter (red) can severely impact galactic scales. Both dark […]
The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]
Scientists are highly skeptical, but such “cosmic wanderlust” isn’t a bad thing.
There are rules absolutely forbidding it from happening. But some particles do it anyway. All the matter we know of in the Universe is made up of Standard Model particles. Photons […]
This technology could close the gap between nature and the man-made environment.
Most of it was eaten by Earth’s mantle, but scraped-off bits survive in the Alps and other mountain ranges.
We’ve put so much together about the Universe. Could it all come tumbling down? We’re always on the lookout for the next big thing, and even our best guesswork is often […]
What should a black hole look like? Our theoretical predictions are about to meet our first observations. In science, there’s no moment more exciting than when you get to confront […]
Gravity and time are so different from what you’d expect. Here’s how it all would end. If you could only know the answer to one question about the Universe, what would […]
Being ahead of the curve can be a dangerous place. These 7 thinkers were driven from their homelands over it.
With an assist from Einstein’s gravity and the power of the Hubble Space Telescope, it’s the brightest quasar we’ve ever discovered. In astronomy, there are two types of questions to […]
Despite being 28 years old and having a gyroscope failure, Hubble still delivered these 10 amazing snapshots in 2018. Year after year since its 1990 launch, Hubble keeps revolutionizing our view […]
When you hear ‘quantum,’ you probably think of splitting everything into discrete, indivisible chunks. That’s not necessarily right. If you want to learn what the Universe is made out of […]
The Universe is expanding, but we, our planet, solar system and galaxy all aren’t. Here’s why. Take a look out at almost any galaxy in the Universe, and you’ll find it’s […]
The expanding Universe really is accelerating, and no dusty scenario can explain it. 20 years ago, our understanding of the Universe underwent a revolution. For generations, we had known the Universe […]
Many renowned writers have revelled in the gifts of their non-native tongues.
Maya Angelou will be commemorated in a new permanent art installation in San Francisco. Poet and novelist, Angelou had a storied relationship with the city. She attended the George Washington […]
If we restrict ourselves to looking for extraterrestrial life on Earth-like worlds, we might miss it entirely. When we think about life out there in the Universe, far beyond the […]
If you look everywhere between the numbers 1 and 2, you’ll never find 3. Let’s say you have an idea about how our physical reality might be different from how we […]
If you think we’ve done a great job with planet-finding so far, just wait until you learn what’s possible with microlensing! When we think about finding planets in the Universe, […]
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever. The ultimate goal of physics is to accurately describe, as precisely […]
There’s a high social cost that comes with lighting up.
The claim comes after two mass shootings over the weekend that killed, in total, 31 people.
A year ago, a puzzling gap existed between black holes and neutron stars. With nearly a year of new data, LIGO solves the puzzle. On Monday, March 16, 2020, astrophysicist Carl […]
