Scientists create 3D-printed universe that fits in your palm

In Greek mythology, Atlas carried the sky on his shoulders, but thanks to physicists and 3D-printing, you can hold the entire universe in your hands, Digital Trends reports. Researchers mapped the oldest light in the universe, which is also called the cosmic microwave background, or CMB. About 380,000 years into its 13.8-billion-year history, the universe shed its opaque foggy cape of plasma and radiation and began to glow, evidence of which is known because of the Planck satellite. The researchers wanted a physical model to better feature temperature differences throughout of the universe in vividly colored bumps and dips, according to a study published today in the European Journal of Physics. You can download and print your own baby universe model, too.
