Dark Matter Revisited

[shellyhe]

Hello folks, After a short hiatus, but always reading new commentary from respected astrophysicists and space jounalists, I proudly remain in the camp that Dark Matter is nothing more than gravity behaving differently at long distances and closely resembles the Modified Dynamics (MOND) theory line. The only discrepancy is that the equations for MOND do not emulate gravity exactly. Other forces in the universe also are affecting the appearance of the galaxies by JWST and other telescopes. This holds true in the cases of Bullet Clusters and Gravitational Lensing examples where MOND is getting so much ridicule. The research for the right answers is continuing, but right now, I am holding form that Dark Matter is not a real substance. And for those other believers that Dark Matter can be something from another universe or dimension that pops in and out of our universe, that will forever remain a mythical event.

I believe that dark matter is what makes up the fabric of spacetime and we won’t find it until we figure out how to look outside of spacetime. If in the early universe the dark matter all condensed at the same time this would have resulted in black holes appearing much larger and gravity wells much deeper. In these wells time would pass more slowly relative to use which would match the slower pulsars and to us faster galaxy developement. Pulsar timing also shows a possible phase transition in the early universe. Over time as the ratio of liquid to gaseous dark matter dropped which reduced the time differential across the universe. Not taking into account the redshift due to climbing out of those gravity wells biases our distance calculations making us think the universe is expanding. It would be interesting to calculate the neutrino mass without the assumption of an expanding universe.
