Gamma-ray bursts are the most powerful explosions in the universe, produced when two dead stars collide and fire cosmic laser beams containing more energy in seconds than our sun will produce in its entire lifetime; if such a burst from thousands of light-years away were to hit Earth, it would instantly vaporize our ozone layer, allowing the sun's radiation to cook everything on the surface, and because these bursts travel at the exact speed of light, we would not see them coming until the sky was already burning.

The Universe's Invisible Sniper Rifle 🔭💥Added:
The universe has a sniper rifle and it might be pointed at us. When two dead stars collide, they fire a gamma-ray burst. It's a cosmic laser beam containing more energy in seconds than our sun will produce in its entire lifetime. If one of these beams hits Earth from thousands of light-years away, it would instantly vaporize our ozone layer. The sun's radiation would cook everything on the surface. And the scariest part? It travels at the exact speed of light. We wouldn't see it coming until the sky was already burning.
