  • OKAY

  • @kenny8331 If there was stuff floating way out around the galaxies that cause the lensing I think that could be possible. But there is nothing there, it is a very empty vacuum. Again, it is the fabric of empty spacetime that is warped by graviity and nothing more. (At least, that seems to work as a very accurate explanation. Anything's possible, of course, like we might be in a dream, and so forth. )

  • @randallbsmith how do we know that its not gravities effect on the material around it and that material changing the direction of the light?

  • @kenny8331 No Snells' law refers to the amount of bend caused at the interface between two materials with different indices of refraction. This gravitational lensing stuff is a different way to bend light. It's really the warp in spacetime that gives this effect.

  • sam button is a faggot!

  • I cant believe i'm searching and loving these stuff when i could barely pass math in school.

  • is this explained by snells law? if not why not?

  • I CAST THE FIRE!

  • @fertilizerspike

    Much of my current take on the nature of gravity is briefly explained in comments I've made under the video entitled "Gravity Doesn't Exist" however I didn't write there with any difference between fuzzballs and black holes in mind.

  • @fertilizerspike

    Dark matter is an effect of the massively warped and weirdly self-absorbed space generated by self-breeding spinning sources of a generally-too-closely-related General Relativity mass media. Gravitational lensing, on the other hand, is something often lamely scoffed-at in some vain back-handed triumphalist walk-in-backward scheme typically designed to have people clinging to general relativity even more tightly in defense, or to associate unrelated equally-queered concepts.
