With lasers, researchers can trap particles and move them into a designated shape while another set of lasers emit red, green and blue light onto the particle and create an image. Their technique, called volumetric display, works like an Etch-A-Sketch toy, but uses particles at high speeds. In 2018, researchers from Brigham Young University in Provo, Utah, created a real hologram. By definition, a hologram is a 3D image created from the interference of light beams from a laser onto a 2D surface, and can only be seen in one angle. Not long into the first Star Wars movie, Obi-Wan Kenobi receives a holographic message. This hologram of Princess Leia features the iconic line, "Help me Obi-Wan Kenobi, you're my only hope."

This refers to a condition in quantum mechanics where two entangled particles may be very far from one another, yet remain connected so that actions performed on one affect the other, regardless of distance. In this case, teleportation is based on a phenomenon known as quantum entanglement. Scientists haven't figured out how to teleport humans yet, but they can teleport balls of energy known as photons. Transporting people this way on Star Trek's USS Enterprise had been around since the very beginning of the series, debuting in the pilot episode. The idea behind "beaming" someone up was that a person could be broken down into an energy form (dematerialization) and then converted back into matter at their destination (rematerialization). ![]() (Image credit: Paramount/AF archive/Alamy Stock Photo) (Image credit: Paramount/AF archive/Alamy Stock Photo) The transporter is an iconic feature of the original Star Trek series. ![]()
