Gravitational Lensing simulated with Blender

Gravitational lensing simulation created with Blender. Demonstrates lensing by black holes, galaxies and galaxy clusters all simulated in Blender. I will upload a tutorial to show how to do this in Blender.

so much for having a tutorial up in a couple days. i really want to know how you achieved the lensing effect

[kiran]

It's been 5 years, and the tutorial still not uploaded yet

Excellent and easy to understand explanation and presentation of gravitational lensing.

[kinoko]

Can you at least give me an idea of how you did it? I'm really curious and wondering if I can use it in game engines!

[Jayspiesaresquared]

Can you please make a tutorial for this! I would love to understand how you did it! Very Good!

[iliketrainspwned]

Can you do a tutorial on how to make that lensing effect with the black hole? I'm trying to make a mod, and there aren't a lot of tutorials on making a shader out of it.

Hi Morbius! I'd like to use this simulation in a science education video (not for profit) that's about how we search for dark matter using measurements of black hole lensing. I would give attribution to you and this channel and this video in the description of the video and in text-on-screen during the clip. Could you respond to me and let me know if this is ok?

[BlackIcexxi]

Any chance you'll show how you did this effect?

[khyzan]

So how long did it take to render? other people I've seen say that it took a massive amount of time.

Can gravitational lensing be used to measure the gravitational field of the foreground source?
I would like to test to see if the source follows the inverse square law of gravity.

My hypothesis that Dark Matter is not a WIMP, but maybe is a deformation of space-time by which the curvature of space-time ALONE is the cause of the gravitational effect. Gravity is the consequence of the curvature of space-time. It may be possible that the structure of space-time itself could be warped without the presence of mass. Space-time has been shown to react like a fabric by warping, twisting, and propagating independent of mass. These properties have been proven with observations of gravitational lensing, frame dragging, and now gravitational waves. Fabrics can be stretched, pressured, and/or heated to the point of deformation. Such extreme conditions were all present during inflation, so it is plausible that space-time’s elastic nature could have hit its yield point and permanently deformed. Therefore, if gravity is the consequence of the warping of space-time, and fabrics can be permanently deformed, then a deformation could create a gravitational effect independent of mass. DM could be a microscopic black holes with no mass at the center, so they wouldn't lose their strength via Hawking Radiation.

Prediction: Spacetime's elastic property hits a yield point, so only that part of geodesic's "stretch marks" would remain after inflation stopped. These steep gravitational wells would not follow the inverse square law.
They would be steep tiny gravity wells.
