    "abstract": "New varying speed of light (VSL) theories as alternatives to the inflationary\nmodel of the universe are discussed and evidence for a varying speed of light\nreviewed. Work linked with VSL but primarily concerned with deriving Planck\u0027s\nblack body energy distribution for a gas-like aether using Maxwell statistics\nis considered also. Doubly Special Relativity, a modification of special\nrelativity to account for observer dependent quantum effects at the Planck\nscale, is introduced and it is found that a varying speed of light above a\nthreshold frequency is a necessity for this theory.",
