Magnetism, electricity and gravity are all examples of a non-contact forces. Masses and charges that are involved in non-contact forces have a region around them called a field. Fields can be compared ...

We study the interaction between a plane gravitational wave and electromagnetic fields, analyzing this interaction in the proper detector frame. The gravitational field is treated as an effective ...

In quantum mechanics, charged particles like electrons can be sensitive to the effects of electromagnetic fields, even when placed in a region where both the electric and the magnetic fields are ...

As they fall, however, their effect on the gravitational field at the Earth’s surface decreases. But surrounding these areas are even weaker, unexplained dents in the field.

The gravitational tinkering has revealed a newly small scale to the universe’s weakest force. To detect it required a very controlled lab environment, and diligent math.
