Lightweight and low cost: researchers have developed a new way to make telescope mirrors that could enable much larger, and thus more sensitive, telescopes to be placed in orbit. (Courtesy: Sebastian ...

New cosmic theory: Researchers suggest a mirror universe born with ours could explain the early matter–antimatter imbalance. Physics rules bent: The model allows local CPT symmetry violations during ...

Go find a makeup mirror. There's a good chance you have one in the bathroom. You know the type—it has a surface that shows you a zoomed-in image of your face. If you have one nearby, you can use this ...

Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 8 years old. When I woke up Sunday morning, ...

In physics many subtle phenomena can be studied by allowing waves to interfere with each other. In an interferometer, light waves travel by two different paths, directed from place to place by ...

You raise your right hand and your reflection raises its left. But the top of your head still points up, and your feet still ...

A large metallic mirror previously used as a prototype for a cosmic-ray observatory will be reused by physicists in Germany to hunt for “hidden photons”. These exotic and hitherto unseen cousins of ...

A team of physicists experimentally produces quantum-superpositions, simply using a mirror. Standing in front of a mirror, we can easily tell apart ourselves from our mirror image. The mirror does not ...
