Funded by the Air Force, Brian Gilchrist and his colleagues are developing a new type of thruster that uses nanoparticles as propellant. Much of the engine is etched directly onto a wafer-thin piece ...

Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These ...

Recent advances in theoretical physics have increasingly highlighted the pivotal role of algebraic structures in unifying particle physics with quantum gravity. These approaches leverage sophisticated ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in ...

Up until now, the prospect of anti-gravity technology has been strictly confined to science fiction stories and films alike. However, CERN physicists are set to begin an experiment that may well ...

The Wall Street mantra “greed is good” could soon be adopted by cosmologists to explain the origins of dark energy, the mysterious entity that is speeding up the expansion of the Universe. At a ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The General Relativity picture of curved spacetime, where matter and ...
