PBS Space Time explains Stephen Hawking's prediction of Hawking radiation and how black holes can emit radiation and slowly evaporate. It goes beyond the common particle-antiparticle analogy.

Recommended as an accessible and correct explanation of Hawking radiation for non-physicists.

There's lots of different ways to approach explaining the phenomenon of hawking radiation, PBS space time does a good job here: [VIDEO] Ultimately, hawking radiation does not come from within the event horizon, so it can escape into the wider universe.

The particle-antiparticle explanation is just an analogy and doesn't really cover what actually happens. I thought this video from PBS Space Time explains it really well while keeping it accessible for non-physicists: [VIDEO]

man, watch the PBS YouTube channel SpaceTime. They're short, informative, and very well done. they dedicate a handful of episodes to getting you ready for Hawking radiation. [VIDEO]

Your description of hawking radiation isn't quite accurate. It's a popular misconception. the actual process is not as easy to understand. see below: [VIDEO] That said, what the OP said about "borrowing" electrons I am not sure about.

PBS Space Time - How Much Information is in the Universe? [LINK] It is a finite number and it's a big number, but still finite (and proven). [LINK] Also the playlist Understanding the Holographic Universe from PBS Space Time [VIDEO] and Entropy Explained! [LINK]
