LAST month, I answered a reader question about space-time expansion. They wanted to know what space-time is expanding into, given that we scientists tend to analogise with a balloon that is being ...

A new theoretical paper has tackled the phenomenon of quantum decoherence, the process by which objects slip out of the quantum world and start behaving classically. The paper approaches this in a new ...

They say time waits for no man but David Gozzard might have found a way to at least tame it. The UWA PhD student is investigating ways to more accurately transmit time signals. It is work that will ...

It was the discovery that changed the universe - or rather our understanding of the universe. One hundred years ago today, Albert Einstein presented his theory of general relativity. So for the next ...

The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space-time could present an answer ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember the past and never the future, and why do broken eggs not leap back into ...
