isnt dark matter just something made up so their math would work
[–] Ken_bingo2 ago (edited ago)
Yes it is. And every time respectable physicists find a plausible explanation that doesn't require fantasy math, they are ignored. So much "science" is actually just dogma. Most respectable scientists know this.

i think youre mistaken, its theorized... its never been directly observed
this was my point, it is something invented to make their math work. same as with black holes, does it exist maybe maybe not... but now 2+2=4 for them, but this doesn't mean it exists..

Standard orbital systems see objects further out have longer orbital periods further in. Galaxies, however, don't show this behavior and instead see a mostly constant rate of rotation throughout the system. You can write off dark matter as just a bookkeeping kludge to make mass appear where it has to be to make this absurdity work, but every other theory proposed so far has tripped over some experimental observation or another.

I'd love to see that proven considering the size of our galaxy, and where our solar system approximately is in it, has an orbital period of some odd 26,000 years (and I'd bet money there is no way in hell that is accurate). This means every other galaxy we look at follows that model too. We for absolutely fucking certainty do not have anywhere close to an observation time long enough to determine how long an orbit is of anything in those galaxies unless we are optically resolving the stars closest to the center inside the big glowing spiny ball of glowing dust several billion light years away.
