About This Design
Gravitational Blueshift Square Paper Coaster
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. Add your own text.
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.

Can't wait to use our new Christmas coasters! They are so very cute! I love the whimsical design. Well made, sturdy and sizeable! These coasters are perfect for large casual parties even safe to have out by the pool! Colors are dynamic and vibrant and just as pictured. Quality of print is crisp and well defined with no blur.

Instead of ordering tickets for our paint night we decided to go with coasters for everyone's glass. It was perfect. Everyone loved their coasters most did not want to use but to keep has a memento enjoying both colors.
