Science fiction novels and movies are full of distant ideas and are often the starting point for an action-packed adventure rather than a serious attempt to predict future trends in science or technology. Some of the most common metaphors, such as accelerating a spacecraft to amazing speeds in seconds without crushing passengers, are simply impossible according to the laws of physics as we understand them. However, it seems that the same laws allow for other seemingly unlikely sci-fi concepts, from wormholes to parallel universes. Here is a summary of some of the sci-fi ideas that can be made, at least in theory.

The idea of ​​a wormhole, a shortcut through space that allows for almost instantaneous travel between distant parts of the universe, seems to have been created as an adventurous leader. But under the more formal name of the Einstein-Rosen Bridge, the concept had existed as a serious theoretical concept long before science fiction writers understood it. Get out of here Albert Einstein‘s general theory of relativitydo you see gravity Like distortion of space-time caused by massive objects. Together with the physicist Nathan Rosen, Einstein developed in 1935 a theory that suggested the existence of an extremely strong force of gravity, such as. black holes, can be directly related to each other. Thus, the idea of ​​wormholes was born.
