In a paper published in the physics journal, Classical and Quantum Gravity, Dr. Diego Rubiera-Garcia from the University of Lisbon in Portugal, and his team, posited that a physical object, such as a person or spacecraft, could survive the gravitational forces of wormhole travel. To make the theory and math work, they do have to play fast and loose with Einstein, but that's not a big deal apparently. According to Einstein's Theory of Relativity, the innermost centre of a black hole holds a singularity; a point where gravitational forces are so strong that space and time end. If any object made it to a black hole's event horizon, and eventually its singularity, it would be stretched into infinity; simply put, an infinitely thin piece of infinitely long spaghetti. However, since no evidence exists to support the existence of singularities, physicists have been taking some liberties with the theory. Earlier this year, the theory of the 'naked singularity' was published, which suggests the
