About This Design

Gravitational Blueshift Napkin

Gravitational Blueshift Napkin

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 napkins were beyond my expectations. The material quality, size of napkin and color clarity are perfect. The support team followed this order and provided an extremely tight turn around. The napkins were individually bagged. This was a gift to our organization’s membership and we received many compliments. The clarity of the printing and color matching were perfect. We were so pleased that we immediately ordered other products with the same image and they also were perfect with great quality. I had ordered some samples from another company, those came in smaller while the quality of material and printing that Zazzle did was far superior. Zazzle completed the order of 200 right away while the other company only had 4 napkins in stock.

These napkins added a special touch to our Army boot camp graduation party decor! Great conversation started. Very satisfied with the printing. They washed well too.

The marble print and color is exactly what I was looking for. The fabric is substantial, and washed up nicely. Love the unconventional print. Already ordered another set! Very much as pictured online.
