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.

JWST has brought us more distant views of the early Universe than ever before. Is the Big Bang, and all of modern cosmology, in trouble?
It could evolve, strengthen, decay, or not be alone. Our known Universe contains matter, radiation, and dark energy. While matter (both normal and dark) and radiation become less dense as […]
When you don’t have enough clues to bring your detective story to a close, you should expect that your educated guesses will all be wrong.
Einstein’s laws of gravity have been challenged many times, but have always emerged victorious. Could wide binary stars change all that?
The best evidence for dark matter is astrophysical and indirect. Do new lensing observations point to ultra-light, wave-like dark matter?
There are an estimated two trillion galaxies within the observable Universe. Most are already unreachable, and the situation only gets worse.
If dark energy gets stronger with time, our fate could be an utter catastrophe. When it comes to the entire Universe, one of the biggest existential questions we’re capable of […]
We know the Universe is expanding, but scientists don’t agree on the rate. This is a legitimate problem.
When the Hubble Space Telescope first launched in 1990, there was so much we didn’t know. Here’s how far we’ve come.
Science is an ongoing flirtation with the unknown.
If we were born trillions of years in the future, could we even figure out our cosmic history?
All the things that surround and compose us didn’t always exist. But describing their origin depends on what ‘nothing’ means.
An enormous amount of antimatter is coming from our galactic center. But the culprit probably isn’t dark matter, but merely neutron stars.
Scientists put the most mysterious force in the Universe to the ultimate test. When it comes to the Universe, it’s easy to make the incorrect assumption that what we see is […]
The Universe is supposed to be the same everywhere and in all directions. So what’s that giant “cold spot” doing out there?
When what we predict and what we measure don’t add up, that’s a sign there’s something new to learn. Could it be a new fundamental force?
We know it couldn’t have began from a singularity. So how small could it have been at the absolute minimum?
In General Relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
Some constants, like the speed of light, exist with no underlying explanation. How many “fundamental constants” does our Universe require?
Cosmology is unlike other sciences. When our view of the Universe changes, so does our understanding of philosophy and science itself.
The inside of every black hole leads to the birth of a new Universe. Could our Universe have arisen from one?
Today, the star-formation rate across the Universe is a mere trickle: just 3% of what it was at its peak. Here’s what it was like back then.
The difference between predictions and observations of the magnetic properties of muons suggests a mystery for the Standard Model.
With 5,000 square degrees of data, the Dark Energy Survey has something important to say. For as long as humans have been studying the Universe, we’ve yearned to know the answers […]
For many years, cosmologists have claimed the Universe is 13.8 billion years old. A new paper says no, it’s 26.7 billion. How do we decide?
On larger and larger scales, many of the same structures we see at small ones repeat themselves. Do we live in a fractal Universe?
It started with a bang, but won’t end with one. Instead, it will “rage against the dying of the light” like nothing you’ve ever imagined.
Ever since the start of the hot Big Bang, time ticks forward as the Universe expands. But could time ever run backward, instead?
Look out at a distant object, and you’re not seeing it as it is today. It’s size, brightness, and actual distance are all different.
