Best university in uk

which is best out of:
Oxford, Cambridge, Edinburgh, Warwick or London?
that is for studying cosmology, astrophysics, astronomy etc

Have you researched what the requirements for your chosen course are? if not I suggest you get onto that first and dont apply to just one university, keep your options open, could be even if you do meet the entry requirements they still might not accept your application... Oxford as far as I here is top.

It probably really depends on which courses you're looking to do, Oxford and Cambridge are probably the two best but you might be doing journalism for example which London university may be better for . . .
