The incremental step Partanen and Tukki have taken is to have described gravity in the context of a gauge – a concept of quantum field theory in which the behavior of particles is described in a ...

"A quantum theory of gravity is needed to understand what kind of phenomena there are in cases where there's a gravitational field and high energies," says Partanen.

OTTAWA — Liberal leadership hopefuls are pivoting and responding to the attention-consuming existential threats to Canadian trade posed by U.S. President Donald Trump — a preview of what the ...

Electric charges produce electric fields. These fields determine how other charges respond within this region of space. A field diagram can be used to describe the field within the proximity of point ...

Magnetic Fields of Bar Magnets A magnetic field is the effect we can see from the movement of charges or the spin of electrons. The fields themselves can be static or changing. A field diagram can be ...

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve.

There’s a new entrant in the competition to develop ever-tinier instruments that can detect changes in our planet’s gravitational field — a tabletop device roughly the size of two smartphone ...

What’s new — As it turns out, all they needed to do was build, what the researchers are calling, the tiniest ever laboratory-created gravitational field.
