Pseudogravity That Bends Light Just Like Real Gravity Created by Engineers in a Laboratory (thedebrief.org)

Researchers studying photonic crystals say they have successfully created a form of pseudogravity that bends light just like real gravity. The new technique could have a dramatic effect on advanced communication technologies like 6G, as well as other applications in optics and materials science that could benefit from a no-contact method of manipulating light.

Consider eyeglasses. I have very thick glasses that help me focus by using lenses with different refraction than surrounding air to bend the light. Do I use pseudo-gravity to see?

Then most of the article is about really cool functionality described similar to some electronics basic operations that could potentially grow into logic gates or switches, which would be very cool, and still has nothing to do with gravity.

Refraction=/=gravity

Hard agree
