Wormhole Simulation
Why Worldbuilding Stack Exchange recommends it
Worldbuilding Stack Exchange answerers and askers point to it as a quick visual reference when discussing what a traversable wormhole might look like or how light behaves near one.

What it is
A short 3-minute computer simulation of travelling through a wormhole, uploaded by Hasbi Fathony in 2014. It shows the visual effect of flying into and out of a wormhole mouth, with no narration or in-depth explanation in the description.

As I understand, technically there is not inside, but practically what is in reality the sorounds of the wormhole. The wormholes are, theoretically, created when a portion of space-time us curved enough to touch any other portion (maybe in same time another coords, same cords and another time, all different, etc.). How do you bend space-time? With gigantic amounts of energy/mass. It is speculated that too make it stable you need exotic matter (and I think it is necessary to create a wormhole with a diameter that allows you to cross without crush). [LINK] (source: wikimedia.org [LINK] ) So, in a strict definition, the wormhole is the point where ever two portions touch. And there is no meanin

It is region of negative space-time curvature . Positive space-time curvature, like that caused by a black hole, a star, or even a planet, causes light to bend inward towards the source of gravity. The opposite, where light is deflected away from the "source" (regardless of what it might be) is effectively negative space-time curvature. I'm not sure what could cause such a phenomenon (exotic/negative mass does indeed come to mind), but it should be noted that if you want it to behave consistently with relativistic physics, it would probably not only reflect light but also "accelerate" time for nearby objects compared to distant objects and "repel" mass gravitationally -- so that if you make

So, I the question of what if a black hole hits the earth has been asked to death by various people, but what if the somewhat tamer wormhole hits the Earth? In particular, we'll say that one mouth is floating somewhere in free space, and the other falls into Earth's gravity well. The radius of the mouths is 1 meter. Note, that I am talking about a traversable wormholes [LINK] , as described by general relativity (note that they are predicted to not exist in our universe (hence the alien-geometry [LINK] tag), but are very well understood in the framework of general relativity). In particular, we are talking about an Ellis wormhole [LINK] . Here's a video [this video] in which physicists simulate o
