At the end of the 18th century, the British scientist Henry Cavendish measured the force of gravity between two objects for the first time in a laboratory. The objects in question were lead balls, one ...

Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but one physicist has proposed ...

Thanks to the presence of a natural “zoom lens” in space, University of Chicago scientists working with NASA’s Hubble Space Telescope have obtained a uniquely close-up look at the brightest ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

The mysterious substance known as dark matter may actually be an illusion created by gravitational interactions between short-lived particles of matter and antimatter, a new study says. Dark matter is ...

Paul Lasky receives funding from the Australian Research Council. He is affiliated with the LIGO Scientific Collaboration. In my previous article we discussed the “who, what, when, where and how” of ...
