Some scientists are convinced that there is a mirror world in our universe that affects gravity in the
The three researchers published their findings this week in the journal Physical Review Letters.They say their hypothesis is based on problems with the Hubble constant, a coefficient for the expansion of the universe.The predictions for this constant don't match reality, and scientists are trying to figure out what causesmismatch.
The researchers hypothesized that the reason might bebe a mirror world that we do not yet see. “At first glance, this may seem crazy, but such mirror worlds are described a lot in physics works,” the scientists noted. Such a world could only affect ours gravitationally and determine the Hubble constant.
