Potential energy is the energy stored of position by an object. It is a type of energy that can be converted to other forms and related to some attractive or pushing forces. Gravitational potential ...

Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about that interaction: it conserves energy. But what if one of those things is an ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

A supermassive black hole with a case of cosmic indigestion has been burping out the remains of a shredded star for four years—and it's still going strong, new research led by a University of Oregon ...

When you travel through the Universe, it isn't just a free ride through empty space. Although you might not think about it very often, there are forces arising from the presence of everything else, ...

It should be clear that our world runs on energy. Driving your car, washing your clothes, heating your house, and even running your computer (so you can read this post)—these things all require energy ...

You know times are finally changing in Australia, when a mining company run by the country’s second-richest person, Dr. Andrew “Twiggy” Forrest, opens a green hydrogen and renewables business. And ...
