What exactly are dark matter and dark energy? (Unsolved)<\/h2>\n
\n
\n
\n\u3000The universe is still filled with many mysteries, or rather, it’s shrouded in mystery. Among them, there is something that should exist because the current universe cannot exist without it, yet we have no clear understanding of what it is. That is dark matter and dark energy, isn’t it?
\n
\n\u3000The explanation of dark energy is not explicitly mentioned as being invisible, but is it implying that dark energy is not a form of matter? The more I read the explanations, the more confused I become. It’s difficult to comprehend something that cannot be observed and hasn’t been confirmed to exist through actual observations. Yet, dark matter is believed to make up nearly 27% of the entire universe, while dark energy is estimated to account for about 68% of the entire universe. It’s quite baffling, isn’t it?

\n\u3000It can be understood by comparing the overall mass of the universe with the observed mass that the unobserved components account for about 95% of the universe. However, I can’t help but wonder if it’s truly possible to determine the exact proportions of dark matter and dark energy among them. In the world of mathematics and science, it often happens that things predicted, such as gravitational waves or the Higgs boson, are later confirmed through advancements in scientific technology. So, while I don’t know if they will be observed during my lifetime, there may come a day when dark matter and dark energy are indeed observed. That is, if humanity continues to progress safely in scientific and technological advancements.
\n
\n\u3000When it comes to dark matter and dark energy, I wonder if dark energy is not considered as matter. While dark matter is considered to be matter, it’s puzzling why it hasn’t been observed, even though it should be observable. At times, I find myself speculating that perhaps dark matter could be a substance that exceeds the speed of light, although it’s purely my imagination.
\n
\n\u3000Although it is said that they don’t actually exist, there is a proposal for particles called tachyons, which are always exceeding the speed of light. While I wouldn’t go as far as equating tachyons with dark matter, could it be possible that a substance surpassing the speed of light, like tachyons, is one of the identities of dark matter? Personally, I find it hard to believe that something exceeding the speed of light would result in what we commonly understand as time travel, going back in time from the present to the past or vice versa. Perhaps it relates to the theory of relativity, specifically the general theory of relativity. According to it, matter cannot exceed the speed of light, and as an object approaches the speed of light, time slows down compared to slower objects. Theoretically, exceeding the speed of light would mean reversing our perception of time and moving towards the past. Is that even possible? If time stops when traveling at the speed of light, one might speculate that crossing that threshold would allow us to travel to the past. However, even when moving at the speed of light, time seems to flow slower compared to other objects, suggesting that time is still flowing…
\n
\n\u3000I tend to go off on tangents a lot, which can be troublesome. Anyway, regarding dark matter, if it were a substance that surpasses the speed of light, as I mentioned earlier, I find it difficult to imagine that simply exceeding the speed of light would result in traveling to the past. However, if it were a substance capable of reversing time, even if we attempted to observe it or capture it using observational instruments, by the time we obtain the observation data, the object itself would have already moved into the past. Therefore, it would be impossible to gather any observational data at the exact moment of observation.
\nEven if it doesn’t involve traveling to the past, if we assume that it is a substance surpassing the speed of light, it’s natural to think that our current scientific knowledge and observational instruments, which are based on the understanding that the speed of light is the maximum speed, would be unable to capture it. So, I sometimes speculate that unknown substances may exist that surpass the speed of light, which is deemed impossible according to our current understanding of physics. However, as I write this, I realize that I’m not sure what I was trying to convey. In the end, I’ve become even more confused about what dark matter and dark energy really are.
