Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you wanted to answer the question of what's truly fundamental in ...

The worldline formalism presents an elegant and computationally efficient approach to quantum field theory, recasting field interactions in terms of first-quantised particle paths. By utilising path ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives ...

Among the intriguing issues in plasma physics are those surrounding X-ray pulsars -- collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the ...

The recent confirmation of gravity waves observed by the LIGO project represents a huge breakthrough in physics, verifying Albert Einstein's predictions regarding the effect of mass on space and time ...

Two leading scientists discuss the future of their field. Credit...Ariel Davis Supported by By Dennis Overbye The future belongs to those who prepare for it, as scientists who petition federal ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...
