About This Design

Gravitational Blueshift T-Shirt

Gravitational Blueshift T-Shirt

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.

Perfect for a little boy dealing with school and becoming a big brother. He loves gaming with his dad so was awesome. Great. No flaws or anything different from what was advertised. Very happy little guy.

The t-shirt feels and looks great quality, a good thick cotton. It will be a little big for my son, but that means he will be able to wear it and not out grow it too soon. The print was as described on the order when personalised. True size, shape and colour T-shirt- thanks.
