Imagine a tiny subatomic particle hurtling through space at a mind-boggling speed—so fast that it makes Usain Bolt look like a slowpoke. That’s the Oh-My-God particle for you, discovered by scientists probing the depths of the cosmos for cosmic rays.

It’s not your average particle; it packs the energy of a baseball hurled at 60 miles per hour, yet it’s smaller than a proton. Scientists scratch their heads trying to figure out where these supercharged particles come from and what accelerates them to such incredible speeds.

Some speculate they originate from distant galaxies or cataclysmic cosmic events, while others ponder if they’re remnants of the Big Bang itself.
