Thank you to everyone for the enlightening responses, I’ve learnt many many things and many have them have been in such clear terms that a giant idiot like myself has been able to understand.
The internet is excellent at times.

The best explanation of an event horizon I’ve ever heard is this analogy.
Let’s say you are in a canoe on a river. A little way down river is a waterfall. Right now you are safe and can paddle in either direction. As you get closer to the waterfall the river picks up speed. For a while you will be able to paddle against the current and get to safety. But at some point the current is going to be moving faster than you can paddle and you are going to get pulled over the waterfall. That point is call the event horizon.
Same thing applies with black holes. It’s the point at which there is no escape and you’re going to be sucked into it.
