In a groundbreaking study published in PRX Quantum, researchers led by Enrico Rinaldi have used quantum computing and AI to ...

Understanding singularities is key to resolving gaps in physics, with theories like string theory and causal set theory ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

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 ...

I CAN understand a good deal of H. D.'s courteous reply to my letter (NATURE, Nov. 24, p. 808), for example, that there are degrees in understanding. But much remains as to which I should like ...
