How physics can help us make sense of multiverse madness

If you're a fan of science fiction films, you'll likely be familiar with the idea of alternate universes—hypothetical planes of existence with different versions of ourselves. As far from reality as it sounds, it is a question ...

Visualizing spin angular momentum in water waves

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown. This will help to provide new insights into very different wave ...

Einstein's theory passes rigorous 16-year tests (Update)

An international team has used telescopes around the world, including CSIRO's Parkes radio telescope—Murriyang, to complete the most challenging tests yet of Einstein's general theory of relativity.
