An expert offers a method to find out if we all live in a computer program

Physicists have long struggled to explain why the Universe began with conditions conducive to the evolution of life. Why do physical laws and constants take on very specific values ‚Äč‚Äčthat allow stars, planets, and ultimately life to develop? The expanding force of the Universe, dark energy, for example, is much weaker than theory suggests – …

Einstein's predictions for gravity have been tested on the largest possible scale

Einstein’s predictions for gravity have been tested on the largest possible scale

According to the standard model of particle physics, the universe is governed by four fundamental forces: electromagnetism, the weak nuclear force, the strong nuclear force and gravity. While the first three are described by quantum mechanics, gravity is described by Einstein’s theory of general relativity. Surprisingly, gravity is the one that presents the greatest challenges …

Astrophysicists tell the story of mathematical cosmology

Credit: Unsplash/CC0 public domain Astrophysicists from RUDN University have collected the most important discoveries of modern cosmology from 1917 to the present day. The collected data became an introduction to Philosophical Transactions of the Royal Society A in two parts: from 1917 to 1980 and from 1980 to the present day. Cosmology, the science of …
