An almost 40-year-old theory finally has ‘smoking gun’ evidence for it. During most of their lives, stars burn stably, changing imperceptibly. The rotten egg nebula, at lower right (and shown in […]

Though difficult to watch, films like “Shoah” and “Life of Crime” cover topics that should not be ignored.
50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]
Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.
If you want to know what the Universe is like, you have to look at it in the right way. Only by observing it can we know what the Universe is […]
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
We often laugh at inappropriate things, but not when we are emotionally invested. Laughter cannot be serious. So, can we ever laugh at death?
GPS holds the key, but astronomers can’t do it without help. Since 2019, the night sky — as seen by both human eyes and the telescopes we use to enhance our views of […]
More than 1,000 years ago, Mesoamerican societies conducted one of history’s most interesting experiments in commodity money.
You can’t throw a DART at everything in space.
Psychedelics mess with our prior beliefs, and could help us see what forms these beliefs in the first place.
The thrills and horrors of strange heavenly bodies condensed into one attractive snapshot.
The Hyperloop is physically possible, but engineering challenges will make its construction very difficult. Also, accidents would be catastrophic.
Social isolation, back pain, and screen fatigue getting you down?
This discovery could lead to better treatments for PTSD, borderline personality disorder, and epilepsy.
Do the benefits of plastics outweigh the costs?
Even before the Big Bang, energetic radiation was always present. When it comes to the physical Universe, the notion of “nothing” may truly be possible only in theory, not in […]
Both views are equally spectacular, but unequally informative. Every so often, a creative amateur project highlights our professional achievements. This mosaic shows the region between the constellations of Cygnus and […]
From high school through the professional ranks, physicists never tire of Newton’s second law.
The A.I. system could improve the lives of commercially raised pigs.
On larger and larger scales, many of the same structures we see at small ones repeat themselves. Do we live in a fractal Universe?
Recent discoveries about bodily awareness have changed how scientists think about the nature of consciousness.
NASA was dangerously cavalier about the dangers of the shuttle launches.
Everything else in the universe is either a particle or field. Dark energy behaves as neither, and it may be a property inherent to space itself.
One study estimated that 80% of people include “deviations” from the truth in their online profiles.
Put two grapes close together in a microwave and you’ll get an electrifying result, all because of the physics of plasmas.
The contact binary system KIC 9832227 is worth another look. Astronomers have seen some incredible occurrences across space and time. The nova of the star GK Persei, shown here in an […]
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
It’s one of Einstein’s most bizarre predictions. And it’s true. There’s no such thing as absolute time. No matter where you are, how fast you’re moving, or how strong the gravitational […]
It’s about 7.6 million times faster than what you probably have at home.
