Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
Designed to map galaxies, the SPHEREx mission's first science result is instead about interstellar interloper 3I/ATLAS. No, it's not aliens.
Only 5% of the Universe is made of normal "stuff" like we are. Could there be dark matter or dark energy life, or even aliens, out there?
If atoms are mostly empty space, then why can't two objects made of atoms simply pass through each other? Quantum physics explains why.
In theory, dark matter is cold, collisionless, and only interacts via gravity. What we see in ultra-diffuse galaxies indicates otherwise.
Dark energy is one of the biggest mysteries in all the Universe. Is there any way to avoid "having to live with it?"
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so... solid?
There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here's what they really mean.
The paper does not prove the existence of dark matter, but it mostly eliminates a rival theory called Modified Newtonian Dynamics.
Quarterback Tom Brady was initially overlooked by NFL scouts, but he had vast hidden reserves of character.
The familiar terrain of solids, liquids, and gases gives way to the exotic realms of plasmas and degenerate matter.
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so... solid?
Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary. Here's why that's an extraordinary feat.
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
All religions have totems, rites, and taboos that are considered "sacred." Émile Durkheim believed society is largely underpinned by them.
Reduction is an approach that has been successful in science but is not itself synonymous with "science."
A new study proposes that Hawking radiation could be used to find dark matter in places like primordial black holes.
A new AI-generated map of dark matter shows previously undiscovered filamentary structures connecting galaxies.
The Field Medal was created to elevate promising mathematicians from underrepresented demographics. But has it followed through on that goal?
While this has been a popular debate, the evidence suggests there isn't a strong link between pornography use and erectile dysfunction (ED).
Our Universe cannot be described by normal matter alone. Vera Rubin’s work led the way. Ask an astrophysicist what our Universe is made of, and you’ll likely receive a shocking surprise. […]
