Using quaternions and octonions, I have built a hypothesis that can explain, from nothing but a set of states expressed by ...

When there are multiple models that yield values close to a single observable or calculated quantity, that agreement alone is ...

Interactions between Earth’s solid inner core, its molten outer core and its rocky mantle control how fast the planet rotates.Gregoire Cirade/SPL Earth’s rotation changes by tiny amounts all the time.

For practical purposes, we say that one day—the time it takes for Earth to rotate once on its axis—equates to 24 hours. In reality, different factors across different timescales influence how quickly ...

After 10 years of painstaking work, National Institute of Standards and Technology physicist Stephan Schlamminger has produced a new measurement aimed at one of science's most frustrating questions: ...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.

Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every time we find a new quantum technique, there's a reason it doesn't quite work ...

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. The pursuit was more or ...
