In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

New simulations show flickering black hole signals arise from unstable shocks inside accretion discs, revealing how matter ...

Black holes themselves emit no light, but the matter spiralling into them forms a hot, dense accretion disc that radiates ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...

Vladimir Fock occupies a distinctive place in the history of twentieth-century science, not only for his profound ...

Last year, astronomers were fascinated by a runaway asteroid passing through our solar system from somewhere far beyond. It ...

An equation of motion in the presence of a drag force proportional to the velocity is derived in the framework of alternative ...

Because the moon has less gravity than Earth does, time passes slightly differently there. This effect was first predicted by Einstein's theory of general relativity. For every 24 hours that pass here ...
