Alternative theory of gravity makes a nearly testable prediction
- hacker_9 7y agoFluff piece, light on any interesting details.
- remarkEon 7y agoThe project website seems to have a lot more info (though I don't really understand most of it). The visualizations of this process are pretty intense. http://www.tng-project.org/media/ http://www.tng-project.org/media/
- rjf72 7y agoSeems to be a bunch of words for filler wrapped around one significant paragraph: "The changes to the gas in the outer region of galaxies [by modified gravity modeling] causes higher densities of gas to form there, which in turn increases the efficiency of cooling of that gas. It turns out that an instrument of the Square Kilometer Array radiotelescope will be sensitive to the altered properties of the gas. As a result, it may be able to pick up any deviations from general relativity."
- nestorD 7y agotldr: they simulated the formation of galaxies with general relativity and an alternativ theory and found a property that differs between both simulations and should be measurable with the Square Kilometer Array radiotelescope. (a nice thing is that this is a general approach that could be used to quickly test and unvalidate alternativ models)
- anentropic 7y ago"nearly testable" LOL
