Does infinity exist?

“Is anything in the Universe truly infinite, or is infinity something that only exists in mathematics?” This question came from father and son duo from Edinburgh in Scotland, Tom and Sorely Watson.

First, we investigate the concept of infinity in mathematics with a story of mathematics, music and murder from Steven Strogatz from the Cornell University.

Did you know that there are some infinities that are bigger than others? We discuss the mind-bending nature of infinity with mathematician Eugenia Cheng, author of Beyond Infinity.

Next we turn to physics to see if we can find something in the Universe that is truly infinite.

Theoretical physicist Sean Carroll from Caltech University discusses the infinitely small inside subatomic particles. Plus cosmologist Andrew Pontzen from University College London travels into the heart of a black hole to see if we can find a something that is infinitely dense.

But if we’re looking for something that is infinite, how about the Universe itself? We find out how physicists measure the shape of the Universe, with the help of an orange and a game of Asteroids. However, if the Universe is not infinite, and it has an edge, what is on the other side?

The Evidence: The science of the menopause

Millions of women around the world experience the menopause each year; it’s an important milestone, which marks the end of their reproductive years.

But every individual's experience of it is personal and unique. In some cultures, there's a stigma about this life stage – it's viewed with trepidation and as something to be dreaded. In other cultures, it's considered to be a fresh start - a time of greater freedom when women no longer have to worry about their menstrual cycles.

In this edition, recorded at Northern Ireland Science Festival in Belfast, Claudia Hammond and her expert panel take a global look at the science of the menopause and debunk some myths along the way.

As Claudia and her guests navigate their way through the menopause maze, they look at the most recent academic research in this area. They also discuss the physical and psychological symptoms, the lifestyle changes women can make and the different treatments available, including Hormone Replacement Therapy.

Claudia also speaks to the American biological anthropologist who has dedicated an impressive 35 years of her life to studying the average age of the menopause in different countries - and finds out how hot flushes vary in different cultures. She also speaks to a doctor who is working hard to make women’s health less of a taboo subject in the community where she works. And she hears from a Professor of Reproductive Science who is setting up the UK's first menopause school.
