Gravitational Blueshift Notebook
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. Customise by adding 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.

This arrived So Much faster than I was expecting. I left plenty of time for international shipping and then didn't need it. I wasn't sure how the image would turn out (have never bought a notebook from Zazzle before). I was pleasantly surprised by the quality of the image.
