TIL that scientists found evidence that a natural nuclear reactor existed in Africa 2 billion years ago. There was a uranium deposit large enough to sustain a chain reaction. It was first noticed when a French power plant's uranium shipment from Africa had decreased levels of fissile uranium-235. scientificamerican.com/arβ¦
ElI5: How does the chain reaction in a nuclear bomb end?
In a nuclear bomb/fission, particles crash into other atoms splitting them, causing the chain reaction and releasing massive energy. So why does the chain reaction end? Shouldn't the particles just keep splitting every atom nearby, continuing the reaction?

Why is p-p chain not a viable nuclear fusion reaction for reactors?
I know this is probably a dumb question, but I'd love to know exactly why a p-p chain isn't viable for an earth fusion reactor. Can it ever be? Does it only work at massive scales?
Thanks in advance!

ELI5 Why scientists, before the underwater nuclear test at Bikini Atoll, were afraid a chain reaction would happen with the underwater explosion and what stopped it?
How are Nuclear Fission chain reactions started?
We're all told that in a chain reaction neutrons from split fuel hit more fuel to cause a chain reaction, but where does the first neutron come from to start the process?? Where is it fired from? I can't seem to find this anywhere on the internet. I'm trying to make a realistically operating reactor in a little game I'm making and I want to find some sort of starting point.

How does an uncontrolled nuclear fission reaction (atomic bomb) stop? If it's a chain reaction where one particles splits and hits two more and so on, shouldn't it grow exponentially and consume the entire universe?
