You’d have to throw out a lot of known physics for this to even be a possibility. Here’s why. It’s an undeniable scientific fact that dark matter must exist in order […]

The largest moon in our Solar System, often overlooked, is a water-rich world. Does that mean life? Here on Earth, life took hold very early on in our planet’s history, and […]
Scientists used CT scanning and 3D-printing technology to re-create the voice of Nesyamun, an ancient Egyptian priest.
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
Hubble, our greatest space-based observatory today, is just the beginning. The Hubble Space Telescope has been astronomy’s most revolutionary observatory in history. The stars and galaxies we see today didn’t […]
And a combination of all three might take us farther than ever. If you want to see the farthest objects in the Universe, you have to know not only where to […]
They say that atoms are mostly 99.99999% empty space. But quantum physics says otherwise. If you were to look at what your body is made of, at smaller and more […]
At 35 light-years away, it’s also the 2nd coolest, 2nd widest planet ever found. Despite discovering more than 4000 exoplanets, most remain obscure. Although more than 4,000 confirmed exoplanets are known, […]
Jonathan Berman wants us to have better dialogues.
The only doubts are completely unreasonable. Where did the virus that causes COVID-19, SARS-CoV-2, come from? Over the past few weeks, there’s been a tremendous push — largely among politicians but also […]
An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
The Universe is dark, but the distorted light reveals its presence. When we look at the objects in the Universe, the mass just doesn’t add up. A galaxy that was […]
Remember Stephen Hawking's robotic voice? It wasn’t a robot.
Known as primordial black holes, they could thoroughly change our Universe's history. But the evidence is strongly against them.
Lake Baikal holds nearly one-fourth of Earth's fresh surface water and is the most scientifically interesting lake on our planet.
In our Universe, a left hand reflected in a mirror or pond appears to be a right hand. While most of the laws of nature are symmetric under reflections, obeying […]
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 images and our best computer models don't agree.
Unbelievably enough, it all comes back to Pythagoras. One of the first theorems anyone learns in mathematics is the Pythagorean Theorem: if you have a right triangle, then the square […]
After more than two decades of precision measurements, we've now reached the "gold standard" for how the pieces don't fit.
Are dark matter and dark energy both two sides of the same coin? When it comes to the Universe, what you can easily see isn’t always reflective of all there is. […]
The double-slit experiment, all these years later, still holds the key mystery at the heart of quantum physics. When we divide up matter into the smallest possible chunks that it’s made […]
We can describe what we see happening, but we don’t understand why. Despite our vast cosmic knowledge, enormous unknowns remain. The quantum fluctuations inherent to space, stretched across the Universe […]
One image can give over 100 times the data we now get from Hubble. NASA’s Hubble Space Telescope, launched in 1990, revealed the previously unseen Universe. The most distant galaxy ever […]
NASA’s SOFIA mission is upgraded and back in action, and the Cigar Galaxy makes a perfect target. In theory, cold, neutral gas is the key to stars and galaxies. A visualization […]
And either way, is energy or information conserved? When two things in the Universe that “always” occur meet one another, how do you know which one will win? Gravitational waves, […]
On the largest scales, galaxies don't simply clump together, but form superclusters. Too bad they don't remain bound together.
We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]
The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]
