At very high and very low temperatures, matter takes on properties that open up an entire Universe of remarkable new possibilities.
How efficiently could quantum engines operate?
Fermilab's TeVatron just released the best mass measurement of the W-boson, ever. Here's what doesn't add up.
The James Webb Space Telescope could help scientists learn about the cosmic dark ages and how they ended.
Astronomers used supercomputers and an international network of antennas to create the stunning map.
We cannot deduce laws about a higher level of complexity by starting with a lower level of complexity. Here, reductionism meets a brick wall.
The rhetorical fallout is greater than the radioactive fallout.
More than any other of Einstein's equations, E = mc² is the most recognizable to people. But what does it all mean?
Life is possible because of asymmetries, such as an imbalance between matter and antimatter and the "handedness" (chirality) of molecules.
The Universe has asymmetries, but that's a good thing. Imperfections are essential for the existence of stars and even life itself.
Some U.S. intelligence operatives have suggested foreign adversaries may be using "directed-energy" weapons against Americans.
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
New technology is helping physicists move forward in the search for the Theory of Everything.
In movies and TV shows, aliens look like pointy-eared humans. Is this realistic? If evolution is predictable, then it very well might be.
Particle physics needs a new collider to supersede the Large Hadron Collider. Muons, not electrons or protons, might hold the key.
From high school through the professional ranks, physicists never tire of Newton's second law.
No matter how controversial or politicized our world becomes, science remains humanity's best tool for figuring out how things work.
Many still cling to the idea that we live in a deterministic Universe, despite the nature of quantum physics. Now, the "least spooky" interpretation no longer works.
There are over 100 known elements in the periodic table. These 8 ways of making them account for every one.
Quantum physics isn't quite magic, but it requires an entirely novel set of rules to make sense of the quantum universe.
