Pink Astrophysics Button ShirtDon't worry Ken, you can be an astrophysicist, too! The swirls in the pattern of this sweet button shirt are real science, from a computer simulation of magnetized gas rotating around and falling into a central black hole. The small scale structure shows the messy turbulence that naturally arises in these settings. No matter what, you are Kenough. Shirt is 100% polyester (65% recycled content) with soft feel and UPF 50+ protection. Fabric is OEKO TEX
