Please remember I am a layman.

I watch a lot of science people like Dr. Becky, Cool Worlds, and Anton Petrov to name 3, and there is an Australian physicist that I forget his name. As I listen to these guys/gal talk about either their own or others findings things seem to coalesce in my mind. I forget who it was but one of them brought up something that made me think down that road again.

There is mass changing the course of light, gravitational lensing, that magnifies objects behind it. (I did always find dark matter/energy a little lacking but our understanding is also lacking. Is physics the same all across the universe through time?) Whatever is causing that mass is only affecting gravity in that area but not blocking light. Combine that with one of the multiverse theories (not the bubble universe) and in my mind there is a possibility that the "missing mass" is possibly other whole universe. Supposedly with what is measured only, what, 5% of all mass is visible to us. (Now the way we measure mass is most likely off somehow same with how we measure distance) This lead to my thinking down this road of possibility.

I don’t think dark matter as a placeholder is accurate - it’s not some fully unexplained phenomenon, it’s matter with mass that doesn’t seem to interact with light.

Several of the people I listen to have said this, they do not know what it is just that they observe certain behaviours. At the same time, dark matter effects may be just a product of several forces working together, that we don't yet understand, causing us to think it is physical in nature.

I have no answers, just a lot of questions that lead to thoughts. Perhaps in my lifetime I/we will get these answers, perhaps not, but it is fun to think about and let the mind wander. Much has changed about our understanding of the universe, much of what I learned in childhood has been rewritten as new discoveries were made.

It looks nothing like chatGPT

Well, I have never been accused of being an llm, also never used any of them.

Scientists are trying to figure out what is causing these effects and with no readily available answer they give it a place holder name, it could be a single particle type in larger amounts that do not get affected by the light we see. I think there is a lot they are getting wrong with the age and consistency of the universe over time using the current methods, tho I do accept it as the best we can come up with due to our limited knowledge and data gathering abilities. Every time a new bigger better equipped telescope comes out we learn that we had something wrong and now we can "see" it. With our tenacity we will discover what it all is, or we will get wiped out, one day.

The scientists have not shrugged their shoulders, they are trying to figure it out, atoms were a hypothesis, molecules were a hypothesis, viruses and bacteria were also a hypothesis until we saw them with technology. This hypothesis of mine has been rattling around in my head for years along with the possibility that inside black holes are entire universes like ours. But I am no scientist so even using hypothesis is a strong word. I do watch certain astrophysicists to learn what I can without delving into the maths.

I would guess that my multiple overlapping universes that cannot see or physically interact with each other would be a source of gravity we cannot find the source of that makes our universe the way it is with the spiderweb of matter that was mapped.

What is your hypothesis?
