Opening portals using electromagnetic radiation. Montauk Project

Montauk You may think of this as science fiction, but the Montauk Project is one of the most famous experiments in time and space among conspiracy theorists to date, and there is a lot of material on it. The Montauk Project is a series of classified US government experiments that took place at Camp Hero, near Montauk, New York. The goal of the project was to create psychological weapons, as well as to study the properties of super-strong electromagnetic fields for time travel, teleportation and mental creation of objects.
