It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...

The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

About a year ago, LIGO, the Laser Interferometer Gravitational Wave Observatory, announced they had discovered gravitational waves. It was perhaps the biggest science story of 2016, in part because ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Back in February of 2016, LIGO made an announcement that changed our ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an ...
