  • We have tons of evidence that it happened but our models for explaining and predicting it are bad at consistently and reliably explaining everything we’ve already seen, and each new discovery seems to break those models even more.

    The theory is the model trying to explain how it works. The fact, though, is that we have evidence showing that it did happen, even if we don’t have a unified theory of how it happened.

    Imagine a car crash site, where the cars have definitely crashed, but everyone has different debates about what caused the crash. Imagine further that the specifics of any person’s explanation has a few inconsistencies with what we see. So we’d have the fact that a car crash happened, but lousy theories explaining how it happened.

    So anybody who says dark matter doesn’t exist is plain wrong, the discrepancies are there plain as day.

    There’s dark matter, the real thing that exists and we can “see”.

    No, we have observations that are consistent with the existence of matter that does interact gravitationally with regular matter, but does not appear to interact with light or electromagnetic forces. It’s not like any matter we know about, other than the fact that it seems to have gravity.

    General relativity works really well to explain matter in the solar system. Bigger than that, you have to use something else. The general consensus is that dark matter exists, but it’s not strictly proven, as there are alternative theories.

    Then, even bigger than that, dark matter alone isn’t enough, you need dark energy to explain some observations, if you assume that cosmological constants are constant. If it turns out that they’re not truly universally constant, we might need to modify some theories (including the proposed existence of dark matter and dark energy).


  • Then there’s the theory of gravity, this is our attempt to explain why gravity exists and why it does the things it does.

    Not just the why, but also the what. We didn’t observe gravitational waves until 2015. People have proposed the existence of dark matter and dark energy because observed gravity doesn’t behave as our models would predict at certain cosmological scales.

    Are committee meetings immune to runaway political madness? Who’s on the committee? How does the committee make decisions? Can those decisions be revisited?

    I’m not convinced that today’s state of science is any different than in eras past, tracing all the way back to kings and wealthy patrons throwing their political and economic might behind their preferred scientific endeavors.

    Science was political in non-capitalistic societies, as well. That’s the point of my second paragraph: science requires resources and however a society steers resources to productive uses, a scientist will need to advocate for their research in order for it to get done.

    IMO, HR should hide the identifying information of candidates from people making the hiring decisions

    That would shift towards another metric of whose resumes look the best. That might be an improvement, but we’d still be talking about how much bullshit there is in making your resume perfectly tailored to a particular opportunity. And at that point we’re still talking about the skills that go into a grant application or a submission of a paper to a conference. That’s the soft skills that make science possible, even if submissions are anonymized.

    Only facts should matter, only agreed truth should be the topic the rest of it is very obviously poisoning the entirety of the effort to understand our world.

    I don’t understand how you’d prioritize things using only facts, and not some kind of extrinsic value system that assigns weights to those facts.

    Let’s say you have a huge infrared telescope sitting at a Lagrange point, between the earth and the sun. How would you determine what it should be observing at any given time? There’s only 8760 hours in a year, and the telescope was designed to last for 5 years, with the hope of 10 years. How do you divide up that finite resource?

    Now do the same for every particle collider, double blind medical study, paleontological excavation, test nuclear reactor, etc., fighting for a finite amount of science money, and you’ll have no choice but to define priorities according to projections and uncertainties and value judgments.

    To put it bluntly, science costs money, and persuading people who control money to spend that money is itself a skill.

    Or, zooming out, science requires resources: physical commodities, equipment, the skilled labor of entire teams. The most effective way to marshal those resources is with money, and management/sales skills are necessary to get those resources working together in concert.

    I gotta imagine making the Sahara Desert habitable is a lot easier than making Mars habitable. The Sahara at least has breathable atmosphere, a 24 hour day, solar intensity that our plants are well adapted to using, and is relatively close to resupply from population centers on Earth.


  • I agree.

    I point out that pretty much everyone in that group experiences it, so even those who aren’t in that disadvantaged group should show some empathy towards the experiences of others, that we may never directly encounter ourselves. Part of that empathy, of course, is to provide support and structures for reducing the likelihood that these things happen, and mitigating them when they do happen.

    these people actually exist

    The way it’s been explained to me is that so much of the negative interactions in life come from a tiny, tiny number of offenders who manage to be shitty to dozens and dozens of people. So anyone who has to interact with many different people will inevitably encounter that shitty interaction, while most of us normies would never actually behave in that way.

    Of the literally thousands of times I’ve interacted with a server or cashier, I’ve never yelled at one. But talk to any server or cashier, and they’ll all have stories of the customer who yelled at them. In other words, it can be simultaneously true that:

    • Almost all servers and cashiers get yelled at by customers.
    • Very, very, few customers actually yell at servers or cashiers.

    In other words, our lived experiences are very different, depending on which side of that interaction we might possibly be on.

    When I talk to women in male dominated fields, basically every single one of them has shitty stories about sexist mistreatment. It’s basically inevitable, because they are a woman who interacts with literally hundreds or thousands in their field. And even if I interact with hundreds or thousands of women in that same field, just because I don’t mistreat any of them doesn’t mean that my experienced sample is representative.
