Mass tells space-time how to bend and space-time tells mass how to move. Masses produce space-time wells into which other masses are drawn because of the bending of space-time. Masses have not been observed to produce space-time peaks (I.e. a repulsive force).
Dark matter was postulated as a “patch” to the standard model in order to preserve it while explaining the observation that stars on the edges of rotating galaxies are moving faster than the Newtonian Physics predicts. Since the stars on the galaxy rim are moving faster something which exhibits the ability to tell space-time how to bend must be outside the orbit of those rim stars, attracting them. However, such objects are not seen in optical & radio telescopes, so they are not absorbing or emitting photons or electrons. And, no objects have been observed undergoing sudden changes in momentum due to a collision with an invisible object, aside from stars rimming a black hole.
Dark matter has been vested with the property that the farther away it is from us the greater its ability to bend space-time. Ergo, the observation that galaxies at the edge of the observable universe are moving much faster (even to the speed of light) then galaxies much closer to our own. Paradoxically, because of the properties of homogeneity and isotropism, observers in those distant galaxies would conclude that Dark Matter’s space-time bending ability is much greater here than there.
So, DM (and Dark Energy) cannot be observed, does not exchange energy or particles with normal matter, no sample of it has been collected so its physical and chemical properties cannot be measured, its gravitational power increases with distance (hence does not follow the inverse square law) and to explain all the observations that the standard model does not explain theorists compute that DM accounts for between 75 and 95% of the mass of the universe.
Is it either DM or M-Theory? Both theories have painted Physics into a corner.
It’s actually a great time for theoretical physics, and in many regards similar to the situation that led to the development of quantum physics. I believe that like the Ether concept at the turn of the 20th century, both DM and M-Theory will be abandon in favor of a more satisfactory modification of the standard model which has not yet been proposed. However, as long as Federal research grants control the direction of research we will have to suffer through periods of Lysenkoism.
