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.
It could be. But then again, if it is like this, it sure means the dark matter could not be described using the current physics.
Your idea is not that off, but it can’t be glued with the rest of physics
I suspect that’s a good definition of Dark Matter based on current understanding. Something that doesn’t fit in the current laws.
That’s what’s so exciting, if we can find some way, any way, to interact with it other than gravity, we’ll have something to base a new definition on, along with new laws of physics! 😃
Sadly as it only seems to interact via gravity, that might not happen and best we might get is a good mathematical model to describe it.
It’s not that it doesn’t fit. You can write whatever math you like.
But then you’ll need to match it with observations. That’s where the problem is. You can write a thousand of dozens theories that match the current observations, but they all will be wrong.
Here, for example, a pretty neat paper by an educated author that connects negative temperature with dark matter:
What of it? It doesn’t help humanity. Just another page in the almanac of what dark matter could potentially be
