Time crystals might exist after all (Update)

(Phys.org)—Are time crystals just a mathematical curiosity, or could they actually physically exist? Physicists have been debating this question since 2012, when Nobel laureate Frank Wilczek first proposed the idea of time ...

What happens when Newton's third law is broken?

Even if you don't know it by name, everyone is familiar with Newton's third law, which states that for every action, there is an equal and opposite reaction. This idea can be seen in many everyday situations, such as when ...

New measurement of electron–quark scattering

From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the building blocks ...

Breaking nature's superfluid symmetry

Superfluids are an exotic state of matter in which particles flow without experiencing viscosity. Hiroki Ikegami and colleagues from the RIKEN Low Temperature Physics Laboratory in Wako have now observed another remarkable ...

Cosmology in the lab using laser-cooled ions

Scientists would love to know which forces created our universe some 14 billion years ago. How could – due to a breaking of symmetry – matter, and thus stars and galaxies, be created from an originally symmetrical universe ...
