Gravity

A new way of potentially detecting dark matter

Astrophysicists at the University of Amsterdam contemplated the gravitational waves created by the merger of a neutron star and a black hole. They found...

How earthquakes deform gravity?

Earthquakes convey signals that proliferate at the speed of light and can be recorded well before the relatively slow seismic waves. Even though the...

Solving Newton’s elusive three-body problem

Scientists focused on recent discoveries related to unstable three-body systems, chiefly, that models suggest unstable three-body systems will eventually expel one of their members, with the remaining two forming a stable relationship.

A new way to measure Earth’s gravity

The technique also could be used to measure slight gravitational variations at different places in the world, which may help in mapping the seafloor or finding oil and minerals underground.

Measuring gravity using floating atoms

New approach allows gravitational potentials to be measured by holding, rather than dropping, atoms.

Dark matter may have existed before the big bang, study

Testing the origin of dark matter by observing the signatures dark matter leaves on the distribution of matter in the universe.

When plant roots learned to follow gravity

Scentists have identified crucial components and processes which only developed in seed plants around 350 million years ago to enable fast and efficient gravity-driven root growth.

Milky Way’s central black hole puts theory of general relativity to the test

Almost a century later, Albert Einstein published his iconic theory of General relativity. Now, scientists at the University of California, Los Angeles have tested...

Physicists just made the most precise measurement ever of Gravity’s strength

The Newtonian gravitational constant, G, is one of the most fundamental constants of nature. Still, we do not have an accurate value for it....

Old star clusters could have been the birthplace of supermassive stars

The Milky Way galaxy has more than 150 old globular clusters, each containing a huge number of stars densely packed together and held by...

Scientists Finally Calculated The Speed of Gravity

Recently, scientists made groundbreaking detections that allowed them that gravity does not act instantaneously as Newton thought, instead it propagates at the speed of light. Neil...

Finding the Missing Nature’s Fifth Force

There are four fundamental forces that drive the universe. They are as gravity, electromagnetic, and the strong and weak nuclear forces. But, now scientists are...
