Let's talk about gravity, a force that affects everything around us. If you drop a ball on Earth, it falls at 9.8 meters per second squared. This means that every second, the ball's speed increases by 9.8 meters per second, assuming there's no air resistance.

If a supernova exploded just 50 light-years from Earth, the cosmic radiation would strip away our ozone layer within seconds. The intense radiation would cause immediate mass extinctions, while the remaining life would face lethal doses of cosmic rays, effectively ending life as we know it.

You know what's fascinating? When people ask me about black holes, they're thinking about falling in. But what they don't realize - and this is the cool part - is that time itself behaves differently near these cosmic monsters. I learned this concept at age 13, and it blew my mind.
