About This Design
Gravitational Blueshift Bib
A multi-colored, fractal representation of gravitational blueshifting; the shifting of light toward the blue end of the spectrum that occurs as photons become more energetic when falling into a gravity well. Unlike the more commonly known Doppler blueshift, an apparent effect which is the result of motion towards the observer, gravitational blueshift is real, independent of the received angle of the photon. Gravitational blueshift is a natural consequence of conservation of energy and mass-energy equivalence.

The bib color, letting and material was great. I have purchased items from this company many times and always been pleased so I wouldn't expect anything less. The printing was great

First of all, the shipping was fast. This bib was everything I had hoped for. It has such a smooth feel to it and is machine washable. The colors are vivid and the image quality is just as pictured on the web. Will be happy to give this as a New Baby gift !
