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

A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler ...

In new research, a physicist describes a “shell singularity,” where gravity applies without mass. Today’s theories for dark ...

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 ...

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 ...

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

A suitcase-sized quantum sensor could soon reveal hidden water, oil, and even underground mountains—all by tracking how atoms fall.

"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 ...

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 ...

Mass is mass is mass ... Finding a difference would also clash with Einstein’s theory of gravity, general relativity. So the moon serves up a win not only for Newton, but for Einstein, too.
