If you're thinking of things like superstrings, loop quantum gravity and other "theories of everything" then your friend has gotten confused somewhere. There is certainly no current experiments which we can do in practise, which is widely acknowledged as a flaw. Lots of physicists are trying to work out low-energy consequences of these theories so that they can be tested, but the maths is extremely hard and the theories aren't even well understood in many cases; but that doesn't mean that they've decided that they'll accept them fully and not bother testing them!
