The Cosmic Microwave Background (CMB) is the cooled remnant of the first light that could ever travel freely throughout the Universe. This ‘fossil’ radiation, the furthest that any telescope can see, was released soon after the ‘Big Bang’. Scientists consider it as an echo or ‘shockwave’ of the Big Bang. Over time, this primeval light has cooled and weakened considerably; nowadays we detect it in the microwave domain. It took about 300,000 years for the Universe to cool down to a temperature at

CMY Color Cube with Stand: this special mount reveals the hexagonal outline hidden within every cube- and highlights the “cube within a cube” illusion. Thin films cover parallel sides of the transparent cube in cyan, magenta, and yellow which comprise the elements of the CMY subtractive color model- viewing the cube through various angles allows exploration of interesting combinations of the CMY elements- and contemplation of the physics and psychophysics of color perception. ➡️ Follow the link
