I'm no scientist, but I'm just wondering if Rogue Planets Sub-Brown Dwarfs could solve the math problem for which Dark Matter is being proposed.  Instead of looking for stuff that hasn't been proven to exist, why not focus on all the stuff we haven't found yet.

For example, Dark Matter theory seem to say that our solar system has to have a bunch of unproven stuff all over the place.  Yet scientists aren't even sure how many planets are in our solar system, and the Oort cloud is still somewhat theoretical.

Basically no.

The simplest reason is that, if there were THAT MANY rogue planets and/or dim brown dwarfs — because, if there is in fact dark matter (and it's not completely certain, the dark matter signal could be caused by something totally different and outside our normal conception of matter), there's a hell of a lot of it — it would be impossible not to notice them.

I've been meaning to watch that tv show.

(As mentioned, the answer is almost certainly No, but MACHOs is what you're talking about. c.f. WIMPs or dimensional-leaking weirdnesses in gravity propagation.)

[EuchreJack]

Thanks for the link to MACHOs.

From what I understand, dark matter is mostly just a big ol' IOU modern scientists are leaving for future scientists.

I don't think you can say dark matter anymore.
'Matter of colour'.
