Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
Countries around the world are racing to develop quantum technologies for computing, sensing and communication. Australia is trying not to get left behind.
Our two best theories of nature, quantum mechanics and general relativity, are incompatible with each other in many ways – leaving physicists to dig deeper.

Examining microscopic quantum objects is exceedingly tricky, because their properties are connected to each other. But there could be a new method to measure them as accurately as possible.
Canada is well positioned to gain far-reaching economic and social benefits from the rapidly developing quantum industry, but it must act now to secure its success.
Quantum mechanics raised tough philosophical questions about the nature of the world – and a physicist named John Bell figured out how experiments could answer them.
