Another interesting essay I just read, by way of
The Browser . . .
I usually say something about the whole 'dark
matter' controversy in my Research Methodology (RM) class. I am no theoretical or astrophysicist, and any of
you who know more on this (or not!!) are welcome to correct me or comment. (Here's the Wikipedia link on dark matter). But in simple terms, there is way more gravitational pull in space than
is accounted for by the amount of matter available. Since no one knows
where the excess gravity is coming from, they simply call it 'dark matter' (. .
. and they sneer at social 'science'!). The problem is that no
instrument has so far detected it. But scientists who question the theory
are cast out into the netherworld. As Fry points out,
"Astrophysicists who try to trifle with the fundamentals of dark matter
tend to find themselves cut off from the mainstream." Remember
Kuhn's 'normal science'? As Fry suggests, no one wants to say there
is something wrong with the theory, because it will be too "drastic".
"Physicists could take non-detection as a hint to give up, but there
is always the teasing possibility that we just need a better experiment."
I wonder how they would do in the social sciences!!
Here's the link:
Hope you enjoy it.

After I emailed some of my graduate students this essay, I had an exchange with one of them, Kasturi Moitra. I am pasting the relevant part of our email discussion (with her permission) because it carries the discussion forward.
