It’s not my job to educate you on what could be a brief Google search. Stop being such a cynic. The gravitational lens distortion of distant galaxies is basically impossible without dark matter. Not to parrot the mantra of conspiracy theorists and cultists, but do your own research.
The gravitational lens distortion of distant galaxies is basically impossible without dark matter.
… using our current model of the Universe.
Dark matter, and dark energy in particular, were introduced to make existing models fit the data.
And we will keep using it until we have a better model
Which we don’t, for that matter
You’re speaking as if scientists aren’t constantly trying to create new, better models that fit the data better.
