Physicists have measured gravity at the tiniest scale still

Physicists have calculated the smallest gravitational discipline ever recorded, in an experiment that could aid in the lookup for a unified idea of physics.

Of the 4 basic forces known to physics — the weak and strong interactions, the electromagnetic pressure and the gravitational power — only gravity stays unintegrated into the playbook of physics termed the Normal Model, which describes how the zoo of subatomic particles behaves. Gravity is in its place described by Einstein’s general theory of relativity, but as this breaks down at the quantum scale, our very best photo of the universe is still left divided in two.
