NEWS- Mirror World can solve Hubble constant problem

BY: Arjit Mishra

According to a new paper, an unseen 'mirror world' of particles that interacts with our world only via gravity might be the key to solve a major cosmological problem- The Hubble constant problem.

The Hubble constant basically is the current rate of expansion of the Universe. 

But here exist a major flaw- the predictions for this rate with reference of cosmology's standard model are significantly slower that the rate found with the help of experimental procedures. 

Many cosmologists around the globe have been attempting to solve this problem by altering our current cosmological model but the challenge is to do so without ruining relations between standard cosmological model and various cosmological phenomena for example- CMB(cosmic microwave background).

Now the Researchers have came across though a previously unnoticed mathematical property of cosmological models, which points out that the observations we do in cosmology have an always existing symmetry under rescaling the universe as a whole. This might pave the way to understand why there is a lack of compatibility between different measurements of the Universe's expansion rate.

If the Universe is inheriting this symmetry researchers are led to a marvelous conclusion: that there exist a mirror world very similar to ours but invisible to us except of it's gravitational impact on our world and the mirror world might be containing the particles that are all copies of known particles.
