André Maeder, Honorary Professor in the Department of Astronomy of the Faculty of Science at the University of Geneva (UNIGE) believes that the commonly accepted model of the Big Bang followed by an expansion, which uses dark matter and dark energy, does not take into account the "scale invariance of the empty space".
This expression means that the vacuum and its properties do not change as a result of expansion or contraction: "When we add the hypothesis of the scale invariance of the empty space, we see a very very small term of outward acceleration that opposes the gravitational force," explained Maeder.
On Earth, this term is insignificant, but in very sparse environments, like the edges of a galaxy or clusters of galaxies, it becomes relatively important. It thus makes it possible to account for the high speeds of stars on the borders of a galaxy.
In clusters made up of hundreds of galaxies, the movements observed are faster than what the visible mass would allow. Professor Maeder also finds that his model predicts the acceleration of the expansion of the Universe without any particle or ounce of dark energy being needed.
My question is the same as the one raised by Pr. André Maeder:
Could this indeed be the fall of dark matter ?
The Maeder model, if validated, would solves two of astronomy’s greatest mysteries, 80 years after the contribution of Fritz Zwicky (Swiss as well).
This topic has been put on hold by some moderator.
Myself physicist (University of Geneva), but having worked in others fields, I would have find interesting to hear from those active in the field on what seems to me to be the fall of the dark matter and dark energy. I would appreciate allowing the discussion to happen.
