If it’s true, this work could have ramifications for some of the biggest mysteries of the universe, including learning where ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

As the story goes, mathematician Sir Isaac Newton was sitting in an orchard after supper when he saw an apple fall from a tree. He wondered why apples always fall straight to the ground, instead ...

Now a wild new study suggesting that gravity can exist without mass, conveniently eliminating the need for one of the most ...

The electromagnetic force rules objects with excess charge (like electrons, protons, and socks shuffling over a fuzzy carpet), and gravity steers objects with mass. The first three forces largely ...

A new paper proposes an alternative hypothesis, showing how gravity could exist without mass and produce many of the same effects we ascribe to dark matter. Einstein’s theory of general ...

As the planets began to settle into orbits the pull of gravity from their own center of mass pulled them in on themselves, tugging at each planet’s mass equally towards its center. This strong ...

"But it is the first proof that gravity can exist without mass." More information: Richard Lieu, The binding of cosmological structures by massless topological defects, Monthly Notices of the ...

An exhaustive examination of lunar gravity using data obtained by two NASA robotic spacecraft is offering new clues about why ...

Two recent ultra-deepwater pipeline projects have encountered mass-gravity flows as significant geohazards. The pipelines are the Shell Malampaya Pipeline in the Philippines and the Gazprom Blue ...

What is gravity without mass? Both Newton's revolutionary laws describing its universal effect and Einstein's proposal of a dimpled spacetime, we've thought of gravity as exclusively within the domain ...
