Scientists may have stumbled upon the universe's most powerful particle collider, and by "stumbled," we mean they accidentally wandered into a cosmic particle party that's been raging for eons. The cosmic rays at this celestial bash are topping out at a mind-boggling one peta-electron volt (PeV), which is roughly the energy equivalent of a billion billion Justin Bieber concerts. The implications are profound: scientists might finally understand the mysteries of the universe, or at least figure out how to harness the power of cosmic rays to fuel their morning coffee. Either way, it's a groundbreaking discovery that will surely lead to a new era of intergalactic particle physics or, at the very least, a really cool science fair project.
