In this picture, spins in particles interact with spacetime and endow it with a property called “torsion.” To understand torsion, imagine spacetime not as a two-dimensional canvas, but as a flexible, one-dimensional rod. Bending the rod corresponds to curving spacetime, and twisting the rod corresponds to spacetime torsion. If a rod is thin, you can bend it, but it’s hard to see if it’s twisted or not. |
The
first is general relativity, the modern theory of gravity. It describes
the universe at the largest scales. Any event in the universe occurs as
a point in space and time, or spacetime. A massive object such as the
Sun distorts or “curves” spacetime, like a bowling ball sitting on a
canvas. The Sun’s gravitational dent alters the motion of Earth and the
other planets orbiting it. The sun’s pull of the planets appears to us
as the force of gravity.
