A 3D visualization of gravitational waves produced by two orbiting black holes. | In the next five years or so, scientists are poised to discover proof that space and time can wrinkle in the form of gravitational waves, which was predicted almost 100 years ago by Albert Einstein's general theory of relativity.
“Tracks made by atomic particles from a particle accelerator, a device that speeds up the particles. The eye can’t see protons, electrons, and other subatomic particles, but a camera records their frothy wakes in a chamber of liquefied neon and hydrogen at the Fermi National Accelerator Laboratory in Batavia, Illinois. Physicists study the tracks to learn about the characteristics of the particles that produced them.” - National Geographic, 1978.
