Webb Telescope Discovers Dark Matter Behemoth Lurking In Early Universe
https://www.spacechatter.com/2024/04/23/dark-matter-early-universe/
A galactic oddity 10 billion light years away has astronomers scratching their heads. Dubbed JWST-ER1, this ancient galaxy was recently spotted by the James Webb Space Telescope, and it’s causing quite a stir. Why? Because it seems to be packed with way more invisible matter than anyone expected
More…
> Now, thanks to a cosmic quirk called gravitational lensing, astronomers from the University of California-Riverside have weighed the dark matter in JWST-ER1, which the Einstein ring is surprisingly associated with. And the results are staggering. This galaxy seems to have a dark matter “halo” that’s nearly six times more massive than all its stars combined! It’s like stumbling upon a cosmic elephant hidden in plain sight.
Only six times?
In our universe, the average is 5 units of dark matter to one unit of baryonic matter.
One crazy possibility that occurred to me is that there’s as yet no guarantee that the gravitational force of dark matter operates in agreement with General Relativity. Dark matter gravity may interact by gravitons for example. Which would change the deflection angle of light. It would be interesting to just try it out mathematically.
