Our universe began as a singularity, a point in space that was infinitely hot and dense. The scientific community describes black holes in the same way. But did […]

I was a student of Stephen Hawking’s – here’s what he taught me Like many students of my generation, Stephen Hawking had already had enormous influence on me long before we ever met. When I was hesitating about my A-level choices, it was his book A Brief History of Time that convinced me to continue
