Nope you don't !!!Speak for yourself and do not speak foll all those who pretend they know but in fact don't

Speaking only for myself, EM waves travel in blancmange. Does this help us any, no.

TJ If you want to see opinion rather than people trying to educate using tried and tested facts then cast doubt on a theory that is more open to debate, such as SUSY models of cosmology, neutrinos changing flavour, CPT violation, existence of higgsinos/photinos and other super-symmetric particles/dark matter candidates, galactic formation models. Anything that is at least open to debate and not theories that are so thoroughly tested/used/understood a 16 yr old can be taught it.

Oh, BTW, make sure you do some background reading first so that we know you understand the issues involved.
