If we can’t measure something, we can’t know its true nature. This fundamental limitation hampers our understanding of the quantum world – but it doesn't preclude scientific thinking

When matter falls into a wormhole, the wormhole is expected to collapse – but a probe may be able to send a signal back through before it’s trapped on the other side

Physicist Carlo Rovelli explains the strange principles of relational quantum mechanics - which says objects don't exist in their own right - and how it could unlock major progress in fundamental physics

The physics in this meandering but engrossing novel adds flavour rather than substance, with the focus more on mental health

To make sense of mysteries like quantum mechanics and the passage of time, theorists are trying to reformulate physics to include subjective experience as a physical constituent of the world

Surprising new insights about the strange physics underlying how clocks work could transform our understanding of time's arrow – and hint at how time works at the quantum scale

Physicists have long speculated why our universe seems “just right” for life. The most complex answer might be the simplest – that every other universe also exists

We have made huge progress in understanding some bits of the cosmos, but we’ve hit a brick wall with things like quantum theory and our own minds. Is there a way round?
17 November 2021
We are tiny specks of life in a vast, indifferent cosmos – but to say that decreases the value of our existence is to measure ourselves against the wrong thing

Black holes devour stuff and then shrivel away over billions of years. Explaining what happens to anything that falls in explodes our current theories of physics, says cosmologist Paul Davies
