Black Hole T-Shirt

 

Even light can’t escape the lure of this black hole T-shirt design. The front features a graphical representation of spacetime curvature caused by a black hole, as defined by German astronomer, Karl Schwarzschild, who discovered the critical radius at which a gravitationally collapsing celestial object becomes a black hole. The back shows James Clerk Maxwell’s four fundamental equations, which describe the behavior of electric and magnetic fields in space and time.
