Distorted crystals use 'pseudogravity' to bend light like black holes do

[Admin]

Researchers have used a special crystal to bend the trajectory of light like a black hole would, a phenomenon known as 'pseudogravity.'

This article totally missed any transmission of knowledge about how this arrangement of crystals is related to how gravity affects light paths. It has been known for a long time that materials change the paths of light that passes through them. So, the questions to be answered are:
1. What is new about this?
2. Why is this so much like gravitational effects that it can be used to study gravity, not just mimic gravity with a different phenomenon?

Agree.

A great article! Thanks for it. It may seem like nothing, but when I really think about what these people said about the potential, about the possibilities, that might come of the mimicry, ....
