Interstellar travel is possible through the bending of spacetime from "summary" of The Science of Interstellar by Kip Thorne
In the universe, the fabric of spacetime can be warped and distorted by the presence of massive objects, such as stars and planets. This warping of spacetime is what we commonly refer to as gravity. The more massive an object, the more it warps the spacetime around it, creating a gravitational field.
When we talk about interstellar travel, we are essentially discussing the possibility of traveling between star systems or even galaxies. The distances involved in such travel are vast, and the conventional methods of propulsion used for space travel within our solar system are simply not feasible for interstellar journeys.
One way to potentially overcome this limitation is by harnessing the bending of spacetime itself. By manipulating spacetime in a controlled manner, it may be possible to create a shortcut through the fabric of the universe, effectively bending spacetime to bring two distant points closer together.
This concept is not as far-fetched as it may seem at first glance. In fact, the theory of general relativity, proposed by Albert Einstein, provides a mathematical framework for understanding how spacetime can be bent and warped by the presence of mass and energy.
One intriguing possibility for achieving interstellar travel through the bending of spacetime is the idea of a wormhole. A wormhole is a theoretical tunnel that connects two distant points in spacetime, effectively creating a shortcut through the fabric of the universe.
If we could somehow create or find a naturally occurring wormhole and control its properties, we might be able to use it as a portal for interstellar travel. By entering one end of the wormhole, we could potentially emerge at the other end millions of light-years away in a matter of moments.
While the concept of using spacetime manipulation for interstellar travel is still firmly rooted in the realm of theoretical physics, it represents a tantalizing possibility for the future of space exploration. By continuing to study the nature of spacetime and gravity, we may one day unlock the secrets of bending the fabric of the universe to traverse the vast distances between the stars.
