Tired Light T-Shirt | When Photons Need a Coffee Break

Fritz Zwicky's 1929 alternative to the expanding universe theory - because sometimes even light gets exhausted trying to explain where it's been! This design celebrates the cosmic hypothesis that suggested photons don't expand space, they just need a nap after traveling for billions of years.

Technical Details:

-Retro sci-fi design in dramatic reds and grays
-Features planets looking suspiciously fatigued
-Quality that won't redshift no matter how far it travels
-Pre-shrunk (unlike Zwicky's theory under peer review)

Perfect For:

-Cosmologists with a sense of humor
-People who think light speed needs a speed limit
-Anyone who's ever felt as tired as a billion-year-old photon
-Astronomers who appreciate alternative theories (and alternative facts)
-Those who understand that sometimes even electromagnetic radiation needs a break

Note: No photons were harmed in the making of this shirt, though several complained about their morning commute through the cosmos.
