About This Design

Gravitational Blueshift Invitation

Gravitational Blueshift Invitation

A multi-coloured, fractal representation of gravitational blueshifting; the shifting of light towards 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.

It was easy to put in the text and it came out exactly how I wanted it to. So many styles to choose from that were lovely for a birthday invitation. Quality of invitation was great and overall very happy. Would definitely use again. It was what I expected but wished it did have glitter.
