When research collides: Modified gravity vs. dark matter

Spread the love

Lost in Math Modified gravity is a hypothesis (1983) that attempts to account for the gravitational pull that is otherwise attributed to dark matter (which has never been identified). From Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, at :



But two recent papers re n direct conflict:



Hossenfelder thinks both sides are making it easy for themselves:


One suspects that modified gravity will be judged as a hypothesis largely on whether it can somehow be made to support a (multiverse) cosmology that nature seems not to recognize.



The symmetrons needed to explain dark energy were not found Researchers: Although this is not the end of the theory, it does at least exclude the possibility of symmetrons existing across a broad range of parameters — and “dark energy” is going to have to be explained differently.

    The following excerpt is from the paper “Beyond Einstein: non-local physics” as found on and

    “It is not rotation or “centrifugal force” that keeps the stars separated. The separation is maintained by the same mechanism as with non-rotating star structures like globular clusters. There is a mass-dependent distance where gravitation and the outward expansion of space are at an equilibrium. Gravitation has an inverse square force distribution, but the expansion of space is centerless and uniform. There is necessarily an equilibrium position for these forces. For stars it is a few light years; for galaxies, it is a few million light years. Hence, the galactic stars will not coalesce with each other, but they are still stuck inside the galaxy’s overall gravitation.

    Gravitation seems to have three regions. Gravitational force near a star starts out strong but declines rapidly with distance (the 1/d^2 region). At the gravipause, gravitation is still present, but falls off less rapidly (the 1/d^1 region, or “Hubble space” as it could be called). Beyond that, quantization causes the gravitation to disappear completely (the 1/d^0 region, where it does not decrease at all, because there isn’t any).”
