Not true, regrettably. A great deal of importance used to be accorded to the idea that the material world was created out of 'fundamental particles'. It was the fact that they were fundamental - supposedly of indivisible and imperishable - which gave materialism its cachet. It has been discovered, as is well known, that they are indeed mainly empty space. So why don't we fall through the floor? I think that is what they are investigating at the LHC, isn't it?
