With a little theory and a lot of imagination, fiction writers have entertained us with the possibility of anti-matter for at least half a century. To our knowledge, less than an atom or two of the stuff has ever existed on this earth until now.
High energy physics research has trapped 38 atoms of anti-matter hydrogen for 1000 seconds. This is a significant improvement over past experiments and sixteen minutes may quickly become sixteen hours or indefinitely.
Science begins with observation. Observation of anti-matter will confirm or deny the theoretical and reveal things theory has not anticipated.
Does anti-matter exhibit anti-gravity or other 'anti' properties of ordinary matter? In the next decade, researchers will have an opportunity to observe its characteristics firsthand.
