OK- so most of the universe is made up of "dark matter"- which doesn't show up on any of our scientific instruments- and "dark energy"- which is even more elusive. As one of the sceptical participants in last night's Horizon grumbled, "this isn't physics, it's fairies at the bottom of the garden."

Exactly.

Am I being naiive, or does this mean that scientific materialism is finished? Or, to put it another way, who's to say that ghosts and fairies (and angels and demons and djinns and gods and goddesses and Bigfoot and the Loch Ness monster) can't exist when it's scientific orthodoxy that most of the stuff in the universe is something other than matter as we know it?

They're all just stories, right? I mean, from my (scant) knowledge of modern cosmology, dark matter/energy seems to be a way of saying "the world is like this, according to all our observations, but we can't really explain it so we'll give it this weird name."

It might end up being viewed by future scientists the way we view "aether." Aether says more about the scientists than science. It's like an inkblot test: what you learn from it is not that there is such a thing as the aether but that people thought there should be some medium through which light travelled. No one knew how this could be, but they did had a name for it. Until later developments refined our understanding.

Now, gravity and whatnot do certain things to certain other things, and no one knows how, so they call it dark matter and dark energy. It's a story.

And that's not that different from fairies and deities: those are just stories to explain rain and war and other big, confusing, and misunderstood things.

That's a good way of looking at it.

Giving something a name creates the illusion that we know what we're talking about- only half the time we don't.

The programme last night featured some guys who've been working down a mineshaft for 16 years trying to capture a particle of dark matter. Thus far they've come up with zilch.

Hmmm...I think my boyfriend is about to join that experiment...is the mineshaft in Italy?

[livejournal.com profile] anarchist_nomad had his PhD in astrophysics. He just accepted a postdoc position at Oxford in which he will be studying dark matter. He'll be over there 2-4 years. Which is exciting for him but dreadful for me since I am in Illinois. LOL

This particular mineshaft was somewhere in the North of England, but I believe similar experiments are being carried out at a number of different sites.

You'll be visiting him in Oxford, won't you?

Sure, I'll visit. But plane tickets costing what they do and my vacation time allotment being as pitiful as it is, I'll be lucky to get over once a year. The ultimate plan is for me to try and move over there but finding a way around all the red tape is problematic. We are polyamorous and marriage is not an option. His primary partner will be living with him and our relationship is too new for me to move in with them so I'd need my own place as well. Many hurdles.
