(PhysOrg.com) -- `Axionlike particles are interesting because they come up regularly when scientists study string theory. By looking at their properties, you hope to learn about string theory, or some other unified theory of physics. From a cosmological point of view, axionlike particles are of interest because they could be connected to dark energy,` Clare Burrage tells PhysOrg.com. The main hiccup in this study of axionlike particles, however, is the fact that their existence - much like their cousins, axions - has yet to be proven.
