This physicist prefers a new theory of gravity

by Indranil Banik, Postdoctoral Researcher in Astrophysics, University of St Andrews 10 July 2022 Dark matter has been proposed to explain why stars at the far end of galaxies can move faster than Newton thought. An alternative theory of gravity may be a better explanation. Using Newton’s laws of physics, we can model the motion of the planets in the solar system with complete accuracy. However, in the early 1970s, scientists discovered that it didn’t work for him. Disc galaxies The stars on their outer edges, away from the gravitational force of all matter at their center, are moving much faster than Newton’s theory predicted. As a result, physicists suggest that the invisible substance called “dark matter” exerts an additional gravitational pull, causing the star to accelerate — a widely accepted theory. However, in a recent review my colleagues and I suggested that observations at multiple scales are much better explained in an alternative theory of gravity called Milgromian or

By Indranil Banik, Postdoctoral Researcher from Astrophysics, University of St Andrews 10 July 2022 Dark matter is proposed to explain why stars at the far edges of galaxies can move faster than Newton predicted. An alternative theory of gravity may be a better explanation. Using Newton’s laws of physics, we can model the motion of the planets in the Solar System quite accurately. However, in the early 1970s, scientists discovered that this did not work for disk galaxies – the stars at their outer edges, away from the gravitational force of all matter at their centres – moving much faster than Newton’s theory predicted. As a result, physicists proposed that an invisible substance called “dark matter” exerted an extra gravitational pull, causing the stars to accelerate – a theory that became widely accepted. However, in a recent review, my colleagues and I suggested that observations at multiple scales are much better explained in an alternative theory of gravity called Milgromian o
