Hubble Constant
I read through my GL books and sketched out some ideas for titles. I didn’t want to do the same thing as last year, which was weak gravitational lensing, as it’s basically statistical analysis, and I prefer the strong lensing ideas.
Dark matter is too complex an argument to have in a 5000 word essay, so I really don’t want to go down that route – I have a basic dislike of the stuff anyway. Ten quid says they don’t find it with the LHC.
Planets are done. Everyone talks about planets (found through microlensing I believe). We have 9(ish) planets in our system – how many have life? One. Rubbish. Planets aren’t exciting. They’re all rocky.
So, I’m going to look at the caulcation of the Hubble Constant. This gets me into Cosmology 
, strong lensing of Quasars , and there’s a wealth of literature. Plus, I can compare with the WMAP measurements.
So, something like “determining the hubble constant with gravitational lensing”. Just checking with the tutor. I’ve also updated/revised Project Plan and Skills docs. Just the others to do tomorrow.
