When you mean 100% invisible, are you talking across all spectrums?

That's pretty neat. So is it assumed that dark matter has been around just as long as all the matter we can see?

That is a very cool topic to be working on. What was your path to get to the point you are at? Not specific schools, but majors, PhD, all that good stuff.

If you don't mind sharing, what was your thesis for your PhD? I'd imagine it would be hard to do a thesis on a subject that is hard to test (financially and practically).
