A pair of scientists from the UK recently published a pre-print research paper discussing the theory of a universe with no beginning. Imagine it: our universe has always existed. The Big Bang either ...

During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...

Researchers have proposed a new interpretation of classical physics without real numbers. This new study challenges the traditional view of classical physics as deterministic. Researchers from the ...

It’s no surprise that quantum physics can be disorienting to the casual observer; after all, it does follow its own set of rules quite different from those of classical physics which rule over our ...

Physicists have been hoping for this moment for a long time: For many years, scientists all around the world have been searching for a very specific state of thorium atomic nuclei that promises ...

Editor’s Note: Professor WERNER HEISENBERG, who was born in Duisburg in 1901, was awarded the Nobel Prize in Physics in 1932 for his work on the quantum theory. A member of the faculty of the ...

Quantum space and time Physicists have developed no-go theorems that limit quantum processes in space–time causality. (Courtesy: iStock/piranka) Physicists have developed a new theoretical framework ...
