There are more interesting and less implausible TESTABLE hypotheses out there?
Dark matter and dark energy are the simplest (literally single parameter) fits to the cosmological data we see. Why we see data consistent with these parameters (e.g. what is the non-interacting massive particle) is up in the air, but adding multi-parameter new forces without more justification seems a little too interesting.
- WithinReason 5y agoIt's not quite single parameter, since each galaxy needs a parameter to describe the dark matter contained in it to explain the observations about it.
- AnimalMuppet 5y agoYeah. It's more like a single parameter at each point in space. That adds up to a lot of parameters.
- pbhjpbhj 5y agoKinda like an aether ;P Einstein would be happy!
- zmgsabst 5y agoI think the goal is a paradigm shift via ADS-CFT correspondences: Eg, if we’re looking at pseudo-tangles in shadow projections, that would solve why QM looks statistical while relativity looks continuous. But that would raise deep questions about “warp” in the macro and whether galactic scale tangles would generate additional binding energy — ie, dark matter. Large scale tangles hiding mass would explain why we can’t interact with it, for instance.
- uoaei 5y agoThis isn't an argument so much for science as it is for funding of scientific experiments. I don't know about you but I feel like this public, cultural, collective investment of time and energy toward dark-matter-seeking projects is not bearing out. It's worth testing other theories more completely. For instance, I've seen a convincing argument[1] that dark matter researchers consistently underestimate galactic inclination, which in turn results in poor fits between model and data, leading to the epicycle-like fudge inclusion of dark matter as "everywhere we would expect mass to be, given xyz".
