 Colossal Ring of Galaxies Discovered Expanding Like a 'Mini Big Bang' --"Could Force a New Understanding of Gravity"
July 19, 2017


Einstein's theory of gravity may have to be rewritten, after researchers at the University of St Andrews  found a gigantic ring of galaxies darting away from us much faster than predicted. This 10 million light year-wide ring made up of small galaxies is expanding rapidly like a mini Big Bang. The team believes our neighboring galaxy, Andromeda (above), once flew past our own galaxy at close range, creating a sling-shot of several small galaxies.

"In Einstein's gravity paradigm, hypothetical dark matter is always invoked," said Indranil Banik, at the University of St Andrews. "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."

Another nice find!
