Example Sentences

"There are several candidates, but only one of them can be the princess we are looking for. Only when the prince finds the slipper can he identify the real Cinderella. In quantum gravity, we have unfortunately not yet found such a slipper -- an observable that clearly tells us which theory is the right one."

From Science Daily

Returning to the Cinderella analogy, physicists may finally have identified a measurable clue that can help distinguish between competing theories of quantum gravity.

From Science Daily

Ideas such as string theory, loop quantum gravity, canonical quantum gravity, and asymptotically safe gravity all attempt to bridge the gap.

From Science Daily

Efforts to combine the two theories into a single framework known as quantum gravity often run into the same obstacle.

From Science Daily

One prediction shared by several Lorentz-invariance-violating quantum gravity models is that the speed of light may depend slightly on a photon's energy.
