Physics

How do black holes merge and make gravitational waves? Maybe with a little help from their friends.

New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.

Carlo Rubbia, leader of the bold collider experiment that in 1983 discovered the W and Z bosons, thinks particle physicists should now smash muons together in an innovative “Higgs factory.”

A new look at a ubiquitous phenomenon has uncovered unexpected fractal behavior that could give us clues about the early universe and the arrow of time.

Physicists have found examples of “universality” in a system of confined bubbles. The work could help researchers understand the strange behavior of singularities.

Experimenters in Germany have glimpsed the kind of strange, non-atomic matter thought to fill the cores of merging neutron stars.

For the first time, researchers have created a scale model of the twisting loops of the sun’s magnetic field.

Tiny, dim “dwarf” galaxies have been found to hide gas-spewing black holes.

Three experiments have vetted quantum Darwinism, a theory that explains how quantum possibilities can give rise to objective, classical reality.
