There are few sports more exciting than playoff baseball, but behind every pitch there is also a fascinating story of physics ...

almost out of nowhere,” says Mark Van Raamsdonk, a theoretical physicist ... a theory is one of the biggest open problems in physics. One fundamental insight from AdS/CFT is that any theory of quantum ...

While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...
