Hidden variables aren’t ruled out, but they can’t get rid of quantum weirdness. Ever since the discovery of the bizarre behavior of quantum systems, we’ve been forced to reckon with […]
July 4th and New Years Eve are the most dangerous times for a hail of falling bullets from ‘celebratory gunfire.’ “What goes up, must come down,” is an old saying […]
Construction is nearly complete for a camera that will take 3,200-megapixel panoramas of the southern night sky.
Should we build a more powerful collider? A telescope that probes the Universe as never before? Absolutely. Here’s why. Every time someone proposes that we invest in fundamental science — to push the […]
A new study found similarities between the human brain and the cosmic network of galaxies.
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 […]
Esoteric evidence points to a ritual performed by Queen Elizabeth’s court magician John Dee.
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 […]
Black hole mergers are some of the most energetic events in the Universe. Could the gravitational waves they produce ever harm us? The Universe is not a static, stable place. Out […]
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 […]
After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
New research explains why the Moon’s crust is magnetized by debunking one long-standing theory.
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 […]
New research on ankle exoskeletons show promising results.
Time runs backward there. Other physicists are not convinced.
How quickly is it expanding today, and how does that expansion rate change over time? What is the Universe made of? How quickly is it expanding today, and how does that […]
Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]
The highest-energy particles on Earth reach enormous energies, but it’s nothing compared to what the Universe can achieve. Deep underground in Europe, the world’s most powerful particle accelerator lives in a […]
The public sphere should be open to conflict.
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
Want help raising your kids? Spend more time at church, says new study.
The green market is growing exponentially. But will the U.S. seize the economic opportunity?
Ultraviolet LED lights could soon be used to help disinfect air and surfaces in buildings, planes, subways and other spaces.
Introducing the Deep Space Food Challenge.
Even 13.8 billion years after the Big Bang, we can reconstruct the first 3 minutes. About 100 years ago, we began to truly understand the nature of the Universe for the […]
A mysterious startup reveals a groundbreaking solar energy achievement.
There are many reasons why this could be true.
The world is changing, and technology is driving that change. Today, that observation is about as compelling as the insight that water runs downhill. It’s just what technology (and water) […]
New study of gamma rays and gravitational lensing points to the possible presence of dark matter.
