Here we go again
You do mean 'inferred' it...right?
Please show me 'one' measurement of Anti-gravity.
It is all inferred from the bookkeeping of the L-CDM model. And in that model exists a "Hypothesized" particle...the WIMP, which is assigned a value of ~22%, which left the universe missing ~74% until magically in 1998, that missing mass was found, and a very convoluted form of the Cosmological Constant/Lambda/Anti-Gravity was re-introduced.
[
otherwise we would not be talking about it today.]
When the WIMP CDM model was first introduced, because it was figured out that the Non-Baryonic DM HAD to be treated as Mass is Mass Is Mass, otherwise SR and GR would both be in peril...in other words, the Non-baryonic DM could NOT be treated as "Hot" and therefore "Fast/Relavistic", and so MUST be treated as though it were 'cold/slow' and 'more massive', so as to be able to be 'affected' by baryonic Matter, even though it goes right through ALL baryonic Matter, so it could be 'tied' to the galaxies rotation curves and cluster dynamics.
BUT, that could only account for the ~22%, and so left the Missing mass of 74%...enter Lambda/Anti-Matter...something that has NEVER been 'seen', measured, found in ANY experiment, and NOT even understood in any sense of the word, to win the final battle of how our universe is working
