The Ultimate Cosmic Speed Trap

The universe's ultimate speed trap! That sign shows 299,792,458 m/s - literally the speed of light in vacuum. It's like posting a "No Swimming" sign in the Sahara Desert. Photons have been cruising at exactly this speed since the dawn of time, blissfully unaware they're hitting the cosmic speed limit. Einstein's relativity ensures nothing goes faster, so these little massless rebels couldn't slow down even if they wanted to. The real kicker? Photons experience zero time due to relativistic effects - they're born and die in the same instant from their perspective. So not only can't they read the sign, they wouldn't even have time to get upset about it!
