A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

Here’s what you’ll learn when you read this story: Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity.

Albert Einstein's general theories of relativity have been used to create tiny microscopic robots that can essentially "swim" ...

The study of black holes within the framework of general relativity continues to advance our understanding of gravitation under extreme conditions. Black holes, with their intricate interplay of mass, ...

Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...
