WORM HOLES

Most of us are familiar with the fancy scientific term "Worm hole" through movies or YouTube videos. It's bizarre physics and potential for manipulating "Space" and "Time" is what we are interested in. However, like most scientific phenomena, most of us have a pretty vague or partial understanding about how a wormhole works. For instance, the image posted along with this post is what many of us thinks a wormhole might look like. But in reality, a wormhole, if it exists, would be spherical rather than a circular tunnel. This is because we experience space as a 3 dimensional entity (3 D). Movies like "Interstellar" could shed some light on the appearance of worm holes.A wormhole is also called an "Einstein-Rosen Bridge".

A wormhole visualised in 2-D: Wikipedia

A wormhole can be seen as a tunnel having two ends which connects two different points in" Space-Time" (different location,different points in time, or both). This means that a wormhole would be capable enough to connect two points in the same or different universes, separated by billions of light years or even short distances. It can also be a potential candidate for humanity's all time dream of "Time travel". It is based on a special solution we obtain from Einstein's "General Theory of Relativity". Though wormholes are 3-D entities, for ease of visualisation, they can be imagined in 2-D.

For this, think of space as a 2-D surface. Then the wormhole would appear as a hole in that surface, lead inside a 3-D tube, and then resurfacing on a 2-D location as another hole. In terms of 3-D, "holes" can be replaced by "spheres". The below image could be helpful:(not a joke)

Although it may seem as science fiction, wormhole could actually be humanity's most important asset. It's potential for time travel and ability to transfer matter and energy faster than the speed of light would propel humanity to other galaxies. However, most scientists theorise that a wormhole would be very unstable and could collapse even before it could transfer anything. According to many leading researchers, forming a stable wormhole would require "Exotic matter" and "Negative Energy", which are even weirder concepts. Only time would tell whether these amazing entities could actually benefit the technological advancements of humanity and make concepts like inter galactic or inter universal travel possible.

Being one the hottest subjects in the field of physics, a lot of research is being done on this subject in order to find the potential of wormholes. Hope you guys enjoyed this article. Have a nice day.
