To see the faintest, farthest galaxies, scientists will also be able to combine the power of #NASAWebb with the magnification of gravity as a "natural telescope" in space. How? https://go.nasa.gov/2JxAq5t https://twitter.com/NASAUniverse/status/1162042273577783297 …
Gravitational lensing occurs when the strong gravity from a galaxy cluster warps the light from more distant galaxies. Find out how galactic-scale magnifying glasses are shedding some light on dark matter!

Something about your ray tracing & bending doesn't look right. Even the space-time bending is localized to the disturbing mass. If you're using galaxies to do that then the bending isn't as uniform but would account for the area. In that case, your video needs a place holder.
