I used to be told off by Cusp for excessive hand-waving (philosophising about the cosmos), but these days, when I pay little attention to cosmology ‘cos I find it a bit dull and irrelevant to my passing presence in the place, he seems like a totally addicted hand-waver to me :)

OK, but you don’t have a PhD in hand-waving, do you?

Who’d be able to read it?

I was going to say something similar.

Ditto. But for inaccuracy (extrapolating beyond the known).

Approx 3.20. that name rings a bell… Old sssf person?

yes. Cusp.

Your about 2500 posts behind. Try to keep up.

Now watched it and found it very informative.

How come we never hear of this big hole in the ground?

Must be costing a fortune. Who is paying for it?

And why does dark matter have to be particles?

Maybe it only interacts through gravity because it isn’t particles.

It’ll be good to see what they do or don’t find anyway.

Just did an exact binge on “particles are just a formalism” which returned exactly one hit:

sorry we mean particles are a metaphor, an analogy, a name we give to or use to describe certain physical concepts that are not relatively directly accessible to our conventional senses, so that their behaviour can only be otherwise described abstractly, but with enough similarity in their formal descriptions to conventionally sensed and understood particles, that it helps us to make sense of and understand them

Seems reasonable.
