A “dark mirror” universe sounds like a Star Trek plot point filled with fascistic first officers and facial hair, but the idea is actually a newly-proposed theory that could help explain the ever-elusive dark matter that supposedly fills about 85 percent of the known universe.

Various theories have tried to explain why we can’t seem to pinpoint dark matter. Maybe dark matter originated with a second big bang or it’s a self-interacting particle that goes along with a dark force. Could axions be the yet-to-be-detected key to unraveling this mystery, or (as string theory suggests), is the particle hiding in some extra dimension? In the absence of any direct detection of this theoretically pervasive particle, scientists have explored a kitchen sink of ideas, and now a new study published in on the pre-print server arXiv in late January proposes a new one—maybe a “dark mirror” universe, one where atoms failed to form, could be where all this dark matter is hiding.

We’ve seen signs of a mirror-image universe that is touching our own

New experiments are revealing hints of a world and a reality that are complete reflections of ours. This mirrorverse may be able to solve the mystery of the universe’s missing dark matter

AT FIRST glance, everything looks familiar. The clock ticks placidly on the wall, cars motor along outside your window, the story you are reading has the same eye-catching pictures. But something is wrong. The clocks are running backwards. Cars are driving on the wrong side of the road. The article you are reading is written back to front. Suddenly, it clicks. You are looking at your own reflection.

The uncanny world on the other side of the mirror may not seem real to you. But Leah Broussard thinks parallel universes where everything is flipped might be very real indeed. Along with her colleagues at Oak Ridge National Laboratory in Tennessee, she is on the hunt for a universe that is identical to our own, but flipped so that it contains mirror atoms, mirror molecules, mirror stars and planets, and even mirror life. If it exists, it would form a bubble of reality nestling within the fabric of space and time alongside our own familiar universe, with some particles capable of switching between the two.

One theory is that dark matter resides in a “dark mirror” universe that failed to form atoms during the nucleosynthesis of the Big Bang. Every interaction in our universe, the theory explains, would have an accompanying interaction inside the dark matter universe—a new kind of universal symmetry

What is the mirror theory of the universe?

This is the world of dark matter, where the laws of physics diverge from those we know, while its existence influences our own. A new theory proposes that dark matter isn’t just a passive observer but a mirror universe of our reality, albeit with its own broken rules

What is the reverse universe theory?

A wild new theory suggests there may be another “anti-universe,” running backward in time prior to the Big Bang. The idea assumes that the early universe was small, hot and dense — and so uniform that time looks symmetric going backward and forward

What is the illusion universe theory?

A new theoretical physics study suggests that the expansion of the universe may be an illusion — a controversial new mathematical model that could shed light on the nature of dark matter

What is the dark universe theory?

The two largest pieces of the Universe, dark matter and dark energy, are the two that we know the least about, yet nothing less than the ultimate fate of the Universe will be determined by them. Dark matter tends to pull the Universe together, and dark energy tends to drive it apart

What is the shadow universe theory?

Shadow/mirror matter would be a form of matter that is just like our own regular matter, except unseeable and undetectable (other than by gravity). So it could form shadow galaxies and shadow stars and maybe even shadow planets and shadow life. Anything that normal matter could do, shadow matter could also do

What is the bubble universe theory?

The concept of a single, all-encompassing universe has given way to theories proposing multiple or even an infinite number of universes—a concept known as the multiverse. At the heart of this theory is the idea of bubble universes. Each “bubble” represents a separate universe, distinct but possibly similar to our own

What is the infinite universe theory?

Infinite Universe Theory

Not everyone agrees with this idea. The multiverse theory, advanced by other scientists and physicists, says the spaceship would eventually reach the end of our universe, and then transition into another universe — and then another and another and another, for an infinite amount of time

multiverse real in real life?

The multiverse has been an extremely popular storytelling trope as of late. In science, however, multiverse models offer frameworks to justify the observable features of the Universe, but with the downside that these other universes remain undetectable

Does God exist in multiverse?

In this case, since the Universe exists, and since science cannot explain the Universe, only God can explain the Universe. Therefore, God exists

Does math prove God?

Can math actually prove the existence of God 100% or it is all just abstract? Can it prove the existence of something divine? No, it cannot. But mathematics, or rather formal logic, can verify whether God’s existence follows from the premises you adopt, which is what Gödel did with his argument

How many dimensions exist?

There are four dimensions in the observable universe. We live in a four-dimensional universe defined by three spatial dimensions and one time dimension. In other words, it only takes three numbers to pinpoint your physical location at any given moment

The mirror universe

A series of viral articles claimed that NASA had discovered particles from another parallel universe in which time runs backward. These claims were incorrect. The true story is far more exciting and strange, involving a journey into the Big Bang and out the other side

The sensational headlines had muddled the findings of an obscure 2018 paper, never published in a peer-reviewed journal, which argued that our universe might have a mirror reflection across time, a partner universe that stretches beyond the Big Bang. If that’s the case, and a series of other extremely unlikely and outlandish hypotheses turn out to be true, the paper argued, then that in turn could explain a mysterious signal hinting that a completely new particle is flying out of the ice in Antarctica.

The claim that NASA discovered a parallel universe seemed to have been first dreamed up by British tabloid The Daily Star, and the story was then picked up by British and American outlets, including The New York Post. 

Star Trek mirror universe

The Mirror Universe is the setting of several narratives in the Star Trek science fiction franchise, a parallel universe existing alongside, but separate from, the fictional universe that is the main setting of Star Trek. It resembles the main Star Trek universe, but is populated by more violent and opportunistic doubles of its people. The Mirror Universe has been visited in one episode of Star Trek: The Original Series, five episodes of Star Trek: Deep Space Nine, a two-part episode of Star Trek: Enterprise, a storyline woven through the first season of Star Trek: Discovery(continuing with a Mirror Universe character in the main cast of seasons 2 and 3), and several non-canon Star Trek tie-in works. It is named after “Mirror, Mirror“, the Original Series episode in which it first appeared

The ‘mirror world’ theory

The new research, published in the Physical Review Letters by a team of astrophysicists from the University of New Mexico and the University of California, Davis, suggests an unseen “mirror world” dark sector of new particles that are all copies of known particles that exists exists alongside ours and interacts with our world only via gravity.

“In practice, this scaling symmetry could only be realized by including a mirror world in the model—a parallel universe with new particles that are all copies of known particles,” said Francis-Yan Cyr-Racine, assistant professor in the Department of Physics and Astronomy at The University of New Mexico and one of the authors of the new paper. “The mirror world idea first arose in the 1990s but has not previously been recognized as a potential solution to the Hubble constant problem.”

The parellel universe

parallel universe, also known as an alternate universe, parallel world, parallel dimension, alternate reality, or alternative dimension, is a hypothetical self-contained layer or plane of existence, co-existing with one’s own. While the six terms are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term “alternate universe/reality” that implies that the reality is a variant of our own, with some overlap with the similarly named alternate history.

Time travel and parellel universe connection

If it is true, it offers a way to time travel into the past, and change things, without causing paradoxes. One of the first physicists to propose this was David Deutsch in a 1991 study. He argued that if you travel into the past and change something, you will create a second universe, parallel to the original one

Is multiverse related to time travel?

Time Still Marches Forward in the Multiverse

Even if you could concoct some scheme to travel among the alternate universes, those universes still share the same spacetime fabric, marching forward along with us. Thus they all appear to forbid time travel, as the theory goes

Do parallel universes interact with each other?

In this bulk, there are other membranes with their own universes. These universes can interact with one another, and when they collide, the violence and energy produced is more than enough to give rise to a big bang

Does wormhole connect parallel universes?

Wormholes may not only connect two separate regions within the universe, they could also connect two different universes. Similarly, some scientists have conjectured that if one mouth of a wormhole is moved in a specific manner, it could allow for time travel

Are dreams parallel lives?

Some theories suggest that dreams may provide glimpses into parallel realities or alternate dimensions. These dimensions may exist simultaneously alongside our own, yet remain hidden to our waking consciousness

If there was a mirror universe in which time ran backwards, would it mean the future already happened without our knowledge?

Imagine of the universe was collapsing instead of expanding. Uranium would continue to decay. Stars would continue to burn, neutron stars would radiate energy and collapse, white dwarfs continue to darken.

A collapsing universe would not look like time running backwards.

So let’s say there was a type matter in the universe which travelled backwards in time, but we could not interact with it.

By this time such matter would have had countless years to go through decay processes. As such we would have heat death matter being slowly reheated. The backwards matter would consist of unredshifted light, neutrinos, and whatever other matter has no decay process.

I have speculated in the past what if dark matter is this

backwards universe co-residing with out own. In such a decayed state that the only interactions we have are via gravity. The problem is I come up with no testable hypothesis as a result.

How does time travel work in a multiverse?

According to multiverse time travel, when a time traveller travels back in time, they don’t arrive in the past of their universe (that is, the universe from which they came). Rather, the act of their travelling back locates them in a child universe.
