Could gravity be evidence that the universe is a computer simulation?

Could gravity be evidence that the universe is a computer simulation?

We have long taken it for granted that gravity is one of the basic forces of nature – one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose the law of gravity is simply an echo of something more fundamental: a byproduct

Tabletop particle accelerator

A particle accelerator that produces intense X-rays could be squeezed into a device that fits on a table, a new research, which has been accepted for publication in the journal Physical Review Letters, reports. The way that intense X-rays are currently produced is through a facility called a synchrotron light

String theory comeback: scientists are trying new ways to verify the theory

Despite decades of research, there is still no definitive theory of everything. The main candidate is string theory, a framework that describes all forces and particles including gravity. String theory proposes that the building blocks of nature are not point-like particles like quarks (which make up particles in the atomic
