Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

For over a century, physicists have been trying to answer one of the most profound questions in science: Can gravity be unified with the quantum world? While the main model describes the ...

Discover 25 mind bending facts about gravity that will stun you! From everyday wonders to cosmic mysteries, explore how ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, ...
