A research partnership between theoretical physicists and computational physicists at the University of Virginia that may offer new insight into the possibility of a theory of everything or, at the very least, a better understanding of gravity, one of the fundamental forces of the universe

Researchers who have examined whether Einstein's theory of gravity works on the largest possible scale claim that there are deviations that need to be checked and corrected similar to those at small distances that can be answered using quantum theory

Researchers from Prague published in the prestigious journal Physical Review Letters an alternative model for dark matter based on MOND that succeeds in predicting the existence of the cosmic background radiation. This is a significant achievement that the MOND model has so far failed to explain, and for this it has received most of the criticism against it. the price? Two new fields in Teva. The authors of the article hope in the future to prove its existence with the help of the model's unique fingerprints on the gravitational waves.

A new record in the measurement of the gravitational field was broken in a study recently published in the prestigious magazine Nature. Measuring gravity on a microscopic scale, which is significantly weaker than the other forces in nature, is a huge technological and scientific challenge. However, gravitational experiments at the atomic scale are critical to understanding the quantum nature of gravity. In the future, will we be able to stretch the limits of the experiment to single micrograms?
