I had a random idea pop in my head while watching a video describing the relationship between radiation’s energy density and entropy. And I’d like to run it past some people who have a deeper understanding of physics than I.
What if dark matter follows an inverted curve? What if we can’t see it because while energetic it emits less radiation and then will become brighter and hotter as it loses energy? Perhaps it even has reversed entropy too and becomes more energetic over time.
This might be crazy, but dark matter is pretty crazy itself. Am I completely off base, or could that line up with any real theories? Maybe it could work with antimatter instead of dark matter?
Worst case I’m just curious and wrong, best case I inspire someone to discover something new. Thanks
I don’t think this would fit the evidence we currently have for dark matter. If it absorbed energy, then it would be much more visible and detectable, as it would often be blocking light and other radiation from objects behind it (at least slightly) and even a slight drop in brightness when dark matter passes in front of something would be fairly easily detectable. (Unless the effect was extremely tiny, I suppose.)
Since that’s very similar to methods already in widespread use to search for exoplanets, I think we probably would have noticed variations in star brightness as the amount of dark matter between us and the star varied over time.
As far as we can currently tell, dark matter only interacts with the rest of the universe through the gravitational force. It doesn’t absorb or emit any energy. (Except, perhaps, gravitational wave energy.)
Involving antimatter really doesn’t help make anything here more plausible.
