Last night while thinking about galaxies with seemingly large DM halos and me being the skeptic of DM as I am, I got a flash of an interesting idea. Thinking I may not be the only person in the world who has thought of this, I am curious to know if this is a previously discussed idea, or if it simply makes no sense, or if indeed I have come up with a truly original thought ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Mass warps space and the effect is gravity. Some galaxies such as NGC 4555 have large halos of hot gas which simply do not have enough visible mass with which to keep such a halo of gas sticking around, thus DM.
Is is conceivably possible that space can warp for reasons other than the presence of mass (dark or otherwise) which would manifest as a gravitational force? A twist in space in an empty part of the universe could for example attract matter and offer a seed (a place in space and a strong gravity) with which to start forming a galaxy. The galaxy would contribute to the overall gravitational strength present, and the remainder, currently attributed to DM might just come from this local twist in space which would now lie at the center of the galaxy.
Sensible or ridiculous?
