Gravitational Blueshift Photo Block
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. Customise by adding your own text.

The quality of the product for the price was a great deal. It is constructed very well and will continue to enjoy it over years to come. I had sent them a collage photo, it was exactly what I sent them was printed for my acrylic photo block.

Thank you! We recently lost one of our family members in this photo and you did an excellent job of preserving a very important memory. This photo block was exactly what I was looking for. Excellent quality and excellent customer service. I always come back! .
