NAVY BLACK HOLE TSHIRT
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. Custom GBO Logo on right sleeve of the awesome Navy Tee.
