For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum ...

It's a tall order for a modified theory of gravity to explain their bread-and-butter, galactic rotation, and simultaneously hit all of these. Screenshot from Twitter user New Leibniz: https ...

"By understanding quantum gravity, we could solve some of the mysteries of our universe — like how it began, what happens inside black holes, or uniting all forces into one big theory." ...

An illustration of the early Universe as consisting of quantum foam, ... 10.) It might be that to combine quantum theory with gravity, we do not have to update gravity, ...

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 ...

n this illustration, a pulsar (PSR J0337-1715) ... "At some level, the majority of physicists believe that Einstein's theory of gravity, called general relativity, is correct.

Einstein predicted how gravity should work at the largest scales. And he was right, suggests new research. When Albert Einstein introduced his theory of general relativity in 1915, it changed the ...

A British theoretical physicist has developed a theory that could solve one of the universe's biggest mysteries: why its rate of expansion is accelerating rather than slowing down, as predicted by ...
