How to predict the end of the universe

How can we gauge the age of the Universe – and when it might end? Cosmologist Renee Hlozek says we can do so by viewing light that has taken billions of years to reach us.

Renee Hlozek says there are vital clues about the fate of the Universe waiting to be discovered – clues 13 billion years in the making. 

This light has been travelling towards the Earth, formed shortly after the Big Bang. 

Working with the Atacama Cosmology Telescope (ACT) collaboration in South America, Hlozek measures the Cosmic Microwave Background (CMB) radiation to see what this light can tell us about the Universe we live in now – and how long it may last.
