A team of researchers from Imperial College London have managed to create a 3D printable cosmic microwave background (CMB), which is the glow that the universe has in the microwave range that maps out the oldest light in all of the universe. Led by astrophysicist Dr. Dave Clements, the project aims to represent the complex and vast nature of this CMB in 3D printed form, utilizing colors, bumps, and dips on a spherical surface to help physically see and touch the early universe and how it came to formation. For instance, the renowned “CMB cold spot” which is a region in the CMB with particularly low temperatures, can be felt on the 3D printed replica as a small and isolated depression.
