Question: How much force would it take to cause an Apocalypse

Steven Thomson answered on 15 Jun 2015:

That would depend on what type of apocalypse and what type of force! There are four fundamental forces (gravity, electromagnetism and the strong and weak nuclear forces).

Too much gravity, and we’d all get squashed, but it would need to be well over ten times the current Earth gravity. If the electromagnetic force was even a tiny little bit stronger or weaker though, then the universe wouldn’t exist at all! And if the strong and weak nuclear forces were different, then atoms might just fall apart spontaneously, so no matter would be able to exist at all. All of these sound apocalyptic to me!
