Rotation curves and apparent mass of a galaxy

[mike_brandt]

i am working on an alternate explanation of dark matter
i am looking for data sets of rotational and the apperant mass for the same galaxy
multiple data sets would be helpfull.

 

[phinds]

What research have you done so far? What have you found out?

EDIT: Also, what are your qualifications?

 

[mike_brandt]

this is my first looksee

 

[mike_brandt]

ive looked at vera rubins paper

 

[mike_brandt]

ive been a engineer for 40 years working soly on manufactureing. i dont know were the basic data is stored for cosmology

 

[mike_brandt]

my qualifications.
engineer
mechanic
interest in
knots
origami
both from a theoretical point of view
belive in a geometrical/ physical explanation of everything
major dyslexia as an advantage. i dont see things the same way most people do

 

[mike_brandt]

a past responder to the same question suggested the sparc data base
just what i was looking for

sorry you got somthing stuck some where

 

[mike_brandt]

i here there is a patent clerk that might know somthing

Can someone tell me where I can get test subjects?

Undergraduates. They'll do anything for beer money.

@mike_brandt we have been having a little fun with you. As you heard, the idea that you are so incredibly smart that you can solve a long-standing problem without even knowing what and where the data are is kind of funny. And un-humble.

You should probably start with the Wikipedia articles and the references at the end. Those references will themselves have references, and that's where you will likely find what you want. Pay particular attention to review papers.

A few points:

• Comparing yourself to Einstein won't help you make your case. That's something crackpots do. You don't want to be lumped in with them.
• Einstein was not a "clerk". He was hired because he had a doctorate was an expert in electromagnetic theory. A lot of the mythology is unsupported by the actual facts.
• It is helpful to use capital letters and punctuation. Proper English is easier to read, especially for members whose first language is not English. It's only polite. If you can learn all there is to know about Dark Matter, placement of periods is surely not beyond you.

This question, in itself, is fine as a discussion topic, but please keep to that topic, bearing in mind the caution above.

I hear there are plenty of good textbooks that explain his theory. Have you read them? You do realize that the patent clerk you are referring to had read all of the best textbooks on the physical theories that were current in his time? Not to mention published papers in the top journals describing the latest research? (And not to mention working personally with some of the best experimentalists of his day.) He didn't come up with his theories by using origami. He came up with them by making himself an expert in the best current theories.

belive in a geometrical/ physical explanation of everything

Since this forum is about cosmology, let's limit geometric/physical explanations to that for purposes of this discussion.

Then why would you even attempt to jump straight into the deep end of cosmology? Do you understand anything about general relativity, galaxy behavior, or various cosmological models like the FLRW or the LCDM models? Or even basic astronomical phenomena? And when I say 'understand' I don't mean that you've seen some videos on them or read a few articles, but that you actually understand the details about them such that you could probably teach an undergraduate course on the material. If not, then take a few steps back and realize that you're just going to waste your own time if you try to immediately create an alternative explanation of dark matter.

There are people who have been doing astronomy/cosmology research for more than 40 years, with entire careers spent trying to solve this issue using the best astronomical equipment ever built by humanity, with access to supercomputers for detailed modeling, who talk to other astronomers, cosmologists, and physicists on a daily basis, and even they have yet to solve the issue. This isn't something that you can just dip your toes into and make meaningful progress.

Not on physics forums. Please read the rules you agreed to when you signed up.

I'm afraid the answer is "elsewhere".

I also suspect your "original" research is not so original. Not so many ideas are original, and the one most people think is original dates back to 1690 and was preety much demolished in the 19th century. Yes, I'm guessing...but you wouldn't be the first person here to have "come up with it:.,

This thread was borderline problematic to begin with and is now attracting personal speculation and is thus locked.
