Experiment to reveal parallel universe

At Oak Ridge National Laboratory in eastern Tennessee, physicist Leah Broussard is trying to open a portal to a parallel universe.

I don't know about you guys, but my money is on "a waste of time". If she succeeds it's gonna literally change the world.

There is a difference between a 'mirror universe' and mirror particles which would exist in our universe.
Mirror particles have their left/right symmetry switched ( as does a mirror ).

I don't think this about mirror particles. Here's a quote from another article

The experiment itself will involve firing a beam of neutrons at a solid wall with a neutron detector set up at the other side. Normally the detector should pick up nothing at all because the neutrons cannot pass through the wall, however scientists believe that some of them may temporarily "oscillate" in to a mirror universe and back, enabling them to pass through the wall where the detector will pick them up.

It absolutely is, here is another quote from the article:

If the setup is just right — and if the universe cooperates — some of those particles will transform into mirror-image versions of themselves, allowing them to tunnel right through the wall. 

The stuff about parallel universes and "portals" is hyperbole.

So it will not prove parallel universes, even if they succeed?

Certainly not parallel universes.

But if it provides evidence of mirror matter then it is possible (but not certain) that there could be large scale structures equivalent to stars and galaxies, made up of mirror matter. This would exist in our universe but not be directly detectable. That could be described as a "parallel universe" but it requires a bit of journalistic license.

There is a good overview of mirror matter here: https://en.wikipedia.org/wiki/Mirror_matter

Isn't that just supersymmetry?

Not quite. There are multiple symmetries. Some lead to anti-matter, others to supersymmetric particles, others to mirror matter. (There may be others ...)

Thank you very much for un-wooing that! And for widening my horizon!
