Hmmm... I'm wondering if any of that warping might explain some of the observations that lead theorists to dark matter...
Most of the observations behind that fallacious pseudo-theory are based on observations of other galaxies.
Not arguing that the observations aren't real. Just every so-called "hypothesis" for DM is fit to a selected set of observations, and falls over once you bring in other data. In addition, none have yielded testable predictions that have succeeded - those that have made predictions, that can be tested, fail.
And let's not forget that the quantity of "missing matter" is continually being downgraded. To the point where we can probably explain the universal expansion without dark matter, but not the galactic rotation issues.
My personal theory is that if there is dark matter, it's the mass of grant application paperwork for academics who want to be funded to research dark matter. :flame:
Now Dark Energy - at this point, no-one's staking much ego on predictions. They're still observing, measuring, and validating. The theories are clearly initial best guesses, and no-one's creating an industry. But it does indeed look like there's some strange **** happening with gravitation on mega-scale distances that we don't yet understand.
