“Andromeda Once Flew Past Our Milky Way Galaxy At Close Range” –New Discovery Upends Einstein’s Theory of Gravity
“If Einstein’s gravity were correct, our galaxy would never come close enough to Andromeda to scatter anything that fast,” said Hongsheng Zhao, Reader in the School of Physics and Astronomy.
If true, the discovery would force a new understanding of gravity and about our cosmos, as such a galactic flyby only makes sense if gravity weakens more slowly as galaxies drift apart than mainstream thinking suggests.
“In Einstein’s gravity paradigm, hypothetical dark matter is always invoked,” said Banik. “Such a high speed requires 60 times the mass we see in the stars of the Milky Way and Andromeda. However, the friction between their huge halos of dark matter would result in them merging rather than flying 2.5 million light years apart, as they must have done.”
