A star orbiting past our galaxy’s supermassive black hole offered a chance to test relativity as never before. The supermassive black hole at the center of the Milky Way is the […]
Gravity gets weaker as the distance squared. But gravitational waves only get weaker as the distance. Why? One of the things we often just accept about the world is that […]
FOIA release sheds light on the DOD’s own struggle to understand UFOs.
With 1.6 billion households in the world, how does Santa do it? With a little Christmas magic… and a lot of science! How does Santa Claus do it? In one long […]
The Polar Vortex was brutal, but not compared to the rest of the Universe.
Giving our solar system a “slap in the face.”
Is it saying too much to say something doesn’t exist when you have no evidence either way?
There are two classes of so-called “big questions.” The former are invented, and the latter can be fully answered by science.
A mind-bending paradox questions the nature of reality.
Cosmic inflation is what happened before, and set up, the Big Bang. Here’s what it’s like to live in an inflating Universe. Our Universe today is full of matter and […]
LIGO, here on Earth, has exquisitely-precise distances its lasers travel. With three spacecrafts in motion, how could LISA work? Since it began operating in 2015, advanced LIGO has ushered in an […]
Scientists have replicated Albert Einstein’s spooky action at a distance on a massive scale—well, for the quantum world, anyway.
A primer on the infinite of knowledge waiting to be learned.
Number of proton-neutron pairs determine how fast the particles move, results suggest.
Sabine Hossenfeder has some problems with how it’s practiced today.

There’s something very special inside a proton and neutron that holds the key. There are few things in the Universe that are as easy to form, in theory, as black holes […]
The Human Diagnosis Project project is building the world’s “open medical intelligence” system.
13.8 billion years ago, our Universe as-we-know-it came into existence. Here’s what it was like. Looking out at our Universe today, we not only see a huge variety of stars and […]
The solar eclipse of May 29, 1919, was the nail in the coffin of a Newtonian Universe. On May 29, 1919, the world changed forever. For hundreds of years, Isaac […]
The cosmic story of us, from before the Big Bang until today, is a story that all of us share. Enjoy it, in just 200 words. In the beginning, there was […]
The entire device is about the size of an ice chest, and the temperature it achieves will be 10 billion times colder than the vacuum of space.
The Standard Model explains all the particles and interactions we see. But it can’t explain this. Of all the particles that we know of, the elusive neutrino is by far the […]
We speak about it, argue over it, and even fight wars for it. We know it when we see it. But just what is energy, anyway? When it comes to being […]
Stephen Hawking was one of the greatest scientific and analytical minds of our time, says NASA’s Michelle Thaller.

With huge suites of data, we can extract plenty of signals where we know to look for them. Everything else? That’s where AI comes in. At the dawn of the 20th […]
When the Universe gives us clues, we ignore them at our own peril. When you approach the world scientifically, you seek to gain knowledge about how it works by asking it […]
Dark matter, dark energy, inflation and the Big Bang are real, and the alternatives all fail spectacularly. If you keep up with the latest science news, you’re probably familiar with […]
Wormholes might very well be a key feature to our cosmos.
