Could dark matter have arisen from a connected 'dark mirror' universe ?

Scientists have proposed a possible new explanation for the origins and nature of dark matter.
The precise nature of dark matter and dark energy, which are thought to account for up to 96% of the observable universe, remains one of the most important unsolved mysteries in modern physics.

Despite concerted efforts, astronomers have been unable to observe dark matter directly because it does not absorb, emit or reflect any electromagnetic radiation, thus making it impossible to see.

Now in a new study, scientists have proposed that there could be a hidden link that connects both regular matter and dark matter - a new form of symmetry that we have yet to understand.

Dark matter may in fact exist in a type of mirror universe, the study authors propose, with a broken set of rules that helps to balance out aspects of the observable, normal matter universe.
Perhaps in this dark mirror universe, for instance, protons are slightly heavier - making the formation of atoms impossible and resulting in a sea of 'dark neutrons'.

It is even possible that in the chaotic early universe, channels might have opened up between the regular matter and dark matter universes - enabling interactions between them.

If so, in the future scientists may be able to use these to catch a glimpse of this dark mirror universe for themselves.

As things stand, however, there is no definitive evidence that such a universe exists.

There merely guessing. Scientists using their imagination. But I know: without imagination scientists would not have discovered what they did discover. I love it.

Scientists would prefer the word, "hypothesising". It's the same thing but sounds more like you know what you are doing.

I think a better expression - here - would be "educated guess". Still, without imagination we wouldn't literally have come far.

Very interesting hypotheguess.      From the article     Now in a new study, scientists have proposed that there could be a hidden link that connects both regular matter and dark matter - a new form of symmetry that we have yet to understand.                  Balance?  .. Equal ,but Opposite..  ??   Light/Dark . . On/Off. .   One coming out of the other???    Infinite number of ones paired to infinite number of others.  ???  …..  Infinity makes numbers meaningless. ?
