Einstein Had It Part Lxxix Dark Matter Options Einstein Had It Part LXXIX: Dark Matter Options

Albert Einstein, one of the greatest minds of the 20th century, once said, "The most incomprehensible thing about the universe is that it is comprehensible." These words resonate with scientists and researchers who continuously embark on quests to understand the mysteries of our universe. One such mystery that has perplexed experts for decades is dark matter.

Dark matter is a hypothetical form of matter that does not interact with or emit electromagnetic radiation, making it invisible to the human eye and traditional telescopes. Its existence is inferred from its gravitational effects on visible matter in galaxies and the observed expansion of the universe.

With its elusive nature, dark matter remains an enigma. In this article, we will explore some of the options and theories regarding the nature of dark matter. Strap on your scientific thinking hats as we delve into the depths of the cosmos!

1. WIMPs: Weakly Interacting Massive Particles

One of the leading theories surrounding dark matter is that it consists of Weakly Interacting Massive Particles, also known as WIMPs. WIMPs are hypothesized to interact strongly via gravity but exhibit weak interactions with all other known particles.

This theory gained popularity due to the way it can account for the observed behavior of galaxies and other structures in the universe. Scientists are actively searching for evidence of WIMPs through various experiments, including the use of underground laboratories and sophisticated detectors.

2. Axions: The Ghost Particles

Another contender for dark matter is the hypothetical particle called axions. Axions are extremely light and elusive particles that could solve the dark matter puzzle. Initially proposed to explain a discrepancy in particle physics known as the strong CP problem, axions quickly became a potential dark matter candidate.

Recent research and technological advancements have enabled scientists to design experiments specifically aimed at detecting axions. These experiments involve sophisticated setups that can detect the faintest signatures of axions if they exist.

3. Modified Newtonian Dynamics (MOND)

While most theories focus on the existence of new particles, some scientists propose that our understanding of gravity, as described by Newton's laws, might be incomplete. Modified Newtonian Dynamics (MOND) suggests that the gravitational laws governing galaxies and other celestial bodies behave differently at extremely low accelerations.

MOND aims to explain the observations without invoking dark matter, suggesting that a fundamental change in our understanding of gravity may be necessary. However, the MOND theory remains controversial within the scientific community, with proponents and skeptics engaged in lively debates.

4. Hidden Dimensions and Exotic Matter

Could dark matter be a consequence of hidden dimensions and exotic matter lurking beyond our three-dimensional space? Some physicists speculate that dark matter may be a manifestation of particles that exist in additional spatial dimensions.

The existence of hidden dimensions is a fascinating concept explored in theories like String Theory and the Multiverse theory. If these theories prove accurate, the nature of dark matter could be explained by particles that interact with our visible world through these hidden dimensions.

5. Primordial Black Holes

While black holes are typically associated with devouring anything that enters their event horizons, a lesser-known theory suggests the existence of primordial black holes - tiny black holes that formed shortly after the Big Bang. These primordial black holes could contribute to the dark matter conundrum.

If primordial black holes exist, they would provide a unique explanation for the observed gravitational effects attributed to dark matter. Detecting these black holes, though incredibly challenging, could shed light on the true nature of dark matter.


Dark matter is undoubtedly one of the most intriguing mysteries in modern astrophysics. While we have explored several theories and options in this article, it is important to note that none of them have been conclusively proven. The search for dark matter continues, and advancements in technology, experiments, and theoretical physics provide hope that we may soon unravel this cosmic enigma.

Albert Einstein's words remind us that the universe remains comprehensible, even in the face of overwhelming mysteries. As we continue to explore and push the boundaries of scientific knowledge, the possibility of understanding dark matter becomes ever more promising.

So, put on your thinking caps and prepare for an incredible journey of discovery as we strive to unravel the secrets of the cosmos, just as Einstein once did.

Hint: For those who want to avoid the heavy math in this paper or seek a short cut to the final solutions we suggest

It is widely assumed that the ominous dark matter does not sport any time-dependency like most of the ordinary matter with the typical Dirac-terms which have a periodic time-component. The latter thereby separates this “Dirac-matter” into matter (moving “against” time) and anti-matter (moving “with” time). Without this time-dependency, however, matter should not show any electro-magnetic effects and mainly interacts via gravity… at least on longer distances.
Applying Quantum Gravity approaches based on simple metric transformations of the metric tensors solving the vacuum Einstein-Field-Equations, we found solutions which do have such properties. Among the many solutions that we found, there might possibly be some candidates fit to represent what we see (or rather do not “see”) as the so-called dark matter.
