No, Albert Einstein did not make a ship disappear. The idea that Einstein had any involvement in making a ship disappear is a misconception and falls into the realm of urban legends and conspiracy theories.
The story you might be referring to is the "Philadelphia Experiment." According to the urban legend, during World War II, the U.S. Navy conducted a secret experiment called the Philadelphia Experiment in which they tried to render the USS Eldridge, a naval destroyer escort, invisible to radar and teleport it. The legend claims that Einstein's "unified field theory" was used in the experiment.
However, there is no credible evidence to support the existence of the Philadelphia Experiment or any involvement by Albert Einstein. It is widely regarded as a hoax or an embellished story that emerged in the 1950s.
Albert Einstein was a theoretical physicist who made significant contributions to the field of physics, particularly with his theory of relativity. His work focused on understanding the fundamental nature of space, time, and gravity, and he did not engage in experiments involving invisibility or teleportation of objects.
