The phenomenon of dark matter has been seen as a fascinating and mysterious issue for decades, capturing the minds of experts and ordinary readers alike. In their 2019 study, “Dark Matter Haloes and Subhaloes,” Zavala and Frenk seek to explore the changes in the velocity of dark matter particles.1 Since the study is rooted in an appropriately chosen research method and is supported extensively by a robust range of primary and secondary sources of essential evidence for the research.
When studying the research in question and overviewing its advantages, one must give credit to Zavala and Frenk’s choice of the research method.1 The choice of the mixed research methodology that provides an insight into the quantitative relationships between the key variables and at the same time introduces the qualitative descriptions thereof is truly praiseworthy. Furthermore, the integration of different frameworks for examining the quantitative relationships between the properties of dark matter create an opportunity to observe much more nuanced interactions between the variables under analysis.
Furthermore, the quality and range of evidence that the authors have selected allows for a thorough and meticulous assessment of the subject matter. Namely, the authors have managed to support their statements with appropriate examples and references to the existing peer-reviewed, credible studies, therefore, providing the evidence that demonstrates the formation and development of dark matter.1 Moreover, the selected studies demonstrate different types of dark matter formation, such as collisional dumping, offering multifaceted perspectives on the issue.1 As a result, the study becomes especially insightful and credible, with profound evidence supporting its statements and offering a substantial scientific foundation for the key assumptions.
Obviously, the research is not devoid of several minor discrepancies in its design. Specifically, several limitations should be noted as the constraints that may have reduced the validity of its results. Specifically, the fact that the scale used in the study has a maximum length should be mentioned as an admittedly evident limitation of the applicability of the research results. Namely, since the research outcomes are expected to be applied to the entire universe, the limited scale of the conditions generator may lead to questioning the applicability of research outcomes to every possible scenario.1 However, to the authors’ credit, the specified limitations have been addressed to the extent that the selected research design allows. In addition, the generalizability of the study outcomes is exceptional, with the proposed mathematical models for determining the relationships between the key variable and examining the properties of dark matter being impeccable.
By selecting a proper research method that allow answering the research question directly and provide extensive explanation on the changes in the velocity of dark matter particles, Zavala and Frenk manage to conduct robust research on the topic.1 Moreover, the support of a sufficient range and quality of evidence supplied by peer-reviewed primary and secondary studies that Zavala and Frenk have selected as references has made it possible to reinforce the credibility of the research outcomes.1 Thus, while the article has minor issues and limitations, it offers essential information that can be used to further the current research on dark matter and its properties. Overall, their paper can be viewed as a vital contribution to the study of the dark matter and its properties.
