Most Of The Universe Is Missing And We Don't Know Why

Everything you see, touch and are built from is a minority of what the universe is actually made of, and the closer physics looks at the rest, the less the picture holds together. Over the next 3 hours, we move outwards through that problem: from the 85 per cent of matter that is invisible, to the visible matter whose textbook description is admittedly unfinished, to a dimension of space that scientists are now building by hand in a lab, and finally to the question of whether we can ever truly know what reality is made of at all.
