Don't know enough physics to talk about the specifics of this particular experiment/research. But, it seems to me, that we live in the midst of the intersection of the "real" world and the mirror one. Similar to Newton's third law (action/reaction), for anything to exist (or make sense to us), the complement of that thing needs to exist too. For example, if there was only one color, there would be no colors, we need for two colors to exist so we can tell them apart. Things only make sense to us in contrast to what they are not. Following the above concept, you could "split up" (conceptually) the world/universe into explicit complements and you'd have the universe and its mirror. And this is in fact a very old concept, very well illustrated by the yin and yang.

According to modern physics, the total energy of our universe is in fact zero, with matter and radiation contributing to "positive" energy, and gravity and other quantum effects contributing to "negative" energy. This is actually the reason we're able to say that our universe could have arisen from nothing, since only a universe with zero total energy can do that. Therefore, by Occam's razor, we don't need another "mirror" universe to balance out this one.

  I had never considered it like that, but it feels true. Do you have some reference material for the statement that gravity and quantum effects are “negative energy”?

    It's not difficult to derive why the gravitational potential energy must be negative.[0] For the cosmological implications of this fact, there's Lawrence Krauss's book "A Universe from Nothing", also "The Inflationary Universe" by Alan Guth, and Stephen Hawking touches on it in "A Brief History of Time."
