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?

Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

Libby Heaney’s Growler (2024) is a glass sculpture that looks anything but. Despite its crystalline surface, it appears as if viscous, gummy and glutinous as it sags and drips down the side of its ...

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This ...

At the heart of economics lies a deceptively simple idea that shapes everything from market strategy to personal growth: marginal value theory. Those who adhere to it insist that when making decisions ...

A new study reveals that quantum networks can do more than secure communication, they can also test how quantum mechanics behaves in the warped spacetime described by Einstein’s theory of gravity.

A new hypothesis known as the Quantum Memory Matrix (QMM) could help explain some of the biggest mysteries of the universe, including the Black Hole Information Paradox. The idea is that space-time ...

In this paper, quantum theory of a real massive scalar field in the background of a traversable wormhole is examined. The wormhole is supposed to connect two different universes; as a particular ...
