When I began my undergraduate physics degree (around 20 years ago), “What is the theory of everything?” was a question that I heard often. It was used as a label for how theoretical physicists ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

Thomas Hertog tells us how he collaborated with Stephen Hawking on his final theorem — a Darwinian revolution in physics that explains the origin of time.

If the theory holds, it will force a radical rethink on time in physics. According to our theory, assembly can be measured as an intrinsic property for molecules, which corresponds to their size in ...

Scientists propose “DNA of the universe” is gap in Einstein’s hunt for unified physics theory Physicists say they detected a double helix in the fabric of spacetime ...

Melvin Vopson, an associate professor in physics at the University of Portsmouth in the UK, believes that gravity is a sign that we are living in a virtual simulation and the universe is the ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...
