A recent investigation has confirmed the existence of dark matter.

Astrophysics has long relied on the existence of dark matter as a theory to explain observed abnormalities in the universe. In contrast to regular matter, dark matter is opaque and only discernible by its gravitational effects. It does not emit, absorb, or reflect light.
A group of scientists, including those from the University of California, Irvine, have recently carried out computer simulations that offer strong evidence for this elusive element of the universe.

Connecting theory and observation

The key question the study attempts to answer is whether the material that we can directly observe and measure can explain everything about the universe or if the existence of dark matter is required to explain some findings that go unanswered.

As things stand right now, scientists are mostly in agreement that dark matter is required to explain things like how stars and galaxies behave.

The primary author of the study, Francisco Mercado, just completed his doctorate in physics and astronomy at UC Irvine and is currently a postdoctoral scholar at Pomona College.

Our study demonstrates how two alternative universe-describing models can be tested using actual, observed correlations as a foundation. We proposed a robust test to distinguish between the two models,” Mercado stated.

Dark matter’s existence

The team’s method was to perform simulations that included dark matter in addition to conventional matter. The goal of these simulations was to mimic the characteristics of actual galaxies, which are difficult to explain in the absence of dark matter.

These properties do, in fact, match those predicted by a dark matter universe, according to the research.
We demonstrate that numerous genuine galaxies have these traits in their observations. Mercado stated, “If we accept these facts at face value, this reinforces the dark matter model’s status as the theory that most accurately reflects the universe in which we inhabit.

Verifying the function of dark matter

The relationship between the observed matter and the assumed presence of dark matter in galaxies was also investigated in this study.

Additional clarification was given by James Bullock, dean of the UCI School of Physical Sciences. “Observed galaxies seem to obey a tight relationship between the matter we see and the inferred dark matter we detect, so much so that some have suggested that what we call dark matter is really evidence that our theory of gravity is wrong,” Professor Bullock stated. .
Our findings demonstrate that dark matter not only predicts the relationship but also, in many cases, provides a more plausible explanation for observed phenomena than modified gravity. I’m even more certain now that dark matter is the appropriate model.”

“Those who support dark matter-free theories made the very observations that we looked at and where we discovered these traits. That community did very little investigation on these qualities, despite their clear existence. Professor Jorge Moreno of Pomona College stated, “It took people like us, scientists working with both regular and dark matter, to start the conversation.”

The prospects for studying dark matter

“As stars are born and die, they explode into supernovae, which can shape the centers of galaxies, naturally explaining the existence of these features,” added Moreno. “Simply put, the features we examine in observations require both the existence of dark matter and the incorporation of normal-matter physics.”
The researchers are not resting on their laurels, even if the dark matter concept is beginning to be accepted as the most accurate explanation for the cosmos.

“It would be interesting to see if we could use this same relationship to even distinguish between different dark matter models,” Mercado said while outlining his plans for the future. We may be able to constrain the features of dark matter itself if we understand how this relationship varies under different dark matter models.”

As the study progresses, it is hoped that additional simulations and observations will confirm the existence of dark matter and improve our knowledge of its characteristics, possibly leading to ground-breaking findings in our understanding of the universe.
