Is Dark Energy Getting Weaker?

Evidence that dark energy, the mysterious substance pushing the universe apart, is changing. And Geoffrey Hinton, the so-called Godfather of AI.

Astronomers have new evidence, which could change what we understand about the expansion of the universe. Carlos Frenk, Ogden Professor of Fundamental Physics at Durham University gives us his take on whether the dark energy pushing our universe apart is getting weaker.

With the Turing Prize, the Nobel Prize and now this week the Queen Elizabeth Prize for Engineering under his belt, Geoffrey Hinton is known for his pioneering work on AI. And, since leaving a job at Google in 2023, for his warnings that AI could bring about the end of humanity. Tom Whipple speaks to Geoffrey about the science of super intelligence.

And Senior physics reporter at Nature Lizzie Gibney brings us her take on the new science that matters this week.
