About This Design

Gravitational Blueshift Invitation

Gravitational Blueshift Invitation

A multi-coloured, 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.

These personalized Christmas cards were so pretty and the added touch of making it personal was just so perfect! The printing was clear and legible, no bleeding of the ink!

I’m happy i ordered my wedding invitations here, as they were affordable yet good quality! The paper was sturdy and the images and words were printed clearly! I love that they came with free envelopes as well! The color was exactly as it was on my laptop screen, and it was printed clearly! the colors are true to color and are vibrant!
