Quantum Entanglement
Ever heard about teleportation? Well, this "spooky" theory of quantum physics when proved true will help in teleportation in reality. So, what's it? 2 entangled particles will always physically interact with each other irrespective of the distance between them. So, when do entangled particles form? It's better to understand it with an example: A laser beam fired through a certain type of crystal can cause individual photons to be split into pairs of entangled photons. Isn't the theory weird? Its actually proved too! More info to be provided in the next article.
