In fact, portals are more than that. A por. A portal (aka a wormhole) is a theoretical topological feature of spacetime that would be, fundamentally, a shortcut connecting two separate points in spacetime. They are consistent with the general theory of relativity but whether wormholes actually exist remains to be seen.

A system of knowledge about the physical, chemical, and biological universe and the things that occur in it is called science. It is an objective observation that explains the basic rules of nature. Another approach to defining science is as the information gained through practice.

Albert Einstein (1879-1955) While some of his discoveries, like the mass-energy equivalence equation, led to the development of nuclear energy and atomic bombs, Einstein also made significant contributions to quantum mechanics and the theory of Brownian motion, earning him the Nobel Prize in Physics in 1921.

Science is defined as the observation, identification, description, experimental investigation, and theoretical explanation of natural phenomena.
