Particles of light can spend "negative time" passing through a cloud of extremely cold atoms – without breaking the laws of ...

By influencing the nucleus of a titanium atom, they have created new opportunities for storing quantum information.

Ernest Rutherford had recently suggested the atom had a miniature, dense nucleus surrounded by a cloud of nearly weightless electrons. There were a few problems with the model, however.

A quantum computing protocol makes it possible to extract energy from seemingly empty space, teleport it to a new location, ...

By conservative estimates, the universe expanded so much during this period that something the size of an atom ... empty universe will distort another way, and the flat universe of the inflation ...

Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. Bohr's 'solar system' model of the atom is the way that most people think ...

An MIT study suggests that primordial black holes could be dark matter and might cause detectable wobbles in Mars' orbit.

Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the ...

which would hint at physics beyond the Standard Model. Understanding antimatter better could help us answer one of the most profound problems in physics: why are we here? Our best models suggest ...

Because used nuclear fuel can be recycled several times through a fast nuclear reactor, it is worth more than gold.

In the case of Bertin and Solon's model, however, the behavior of the individual elements is a bit more sophisticated than ...

The universe might be teeming with microscopic black holes the size of an atom but with the mass of a city-sized asteroid, scientists say.
