## The physics of black holes

### The Singularity Theorem (Nobel Prize in Physics 2020)

In 2020, Roger Penrose was awarded half of the Nobel prize in physics for proving that black hole formation is a robust prediction of Einstein’s general theory of relativity.

### How many different kinds of black holes are there?

Once they have settled down, there are actually only very few different kinds of black hole – find out which, and how black holes shed other distinguishing marks.

### Changing places – space and time inside a black hole

How, in one sense, space and time switch their roles inside a black hole – and why this leads to a black hole’s most characteristic property, namely that nothing can get out

### Particle accelerators as black hole factories?

The intriguing possibility that the next generation of particle accelerators might produce – and allow the detection of – miniature black holes
