Hello,

Thank you for sharing your thoughts on the topic of dark matter. As a fellow scientist, I am always interested in discussing and exploring different theories and ideas in the field of physics.

I can understand your skepticism towards the existence of dark matter, as it is a concept that is still not fully understood and has yet to be directly observed. However, I would like to offer a different perspective on the matter.

While it is true that dark matter has not been directly detected, there is strong evidence for its existence based on observations of the rotation curves of galaxies, gravitational lensing, and the cosmic microwave background radiation. These observations cannot be explained by the known laws of physics and require the presence of some form of invisible matter.

Additionally, the concept of dark matter is not a new one. It has been proposed and studied by scientists for decades, and there have been numerous experiments and observations aimed at detecting it. While we have not yet been successful in directly detecting dark matter, the search continues and new technologies and techniques are constantly being developed to aid in this pursuit.

I also want to address your point about dark matter being a "placeholder" for our lack of understanding. While it is true that we do not fully understand the nature of dark matter, this does not make it any less of a legitimate concept in physics. Many scientific theories and concepts start off as ideas or hypotheses before they are fully understood and accepted. It is through continued research and experimentation that we are able to gain a deeper understanding of these concepts.

In conclusion, while I respect your skepticism towards dark matter, I believe that the evidence for its existence is strong and warrants further investigation. As scientists, it is our duty to continue exploring and questioning the unknown in order to expand our knowledge and understanding of the universe. I look forward to hearing your thoughts on this matter and engaging in further discussions.
