Universe 15% Older Than Previously Thought?

Astronomers recently calculated the distance to the relatively nearby galaxy M33 (aka the Triangulum Galaxy) as being about 15% further than previously estimated. They analyzed the distance using several telescopes while observing a binary star system, fine tuning their instruments very carefully. This measurement means that the Hubble constant (71 km/sec/mparsec) – which astronomers use to measure distances in the Universe – could be off as well. The Universe might actually be 15% larger (and thus older) than previously believed. (This post mostly courtesy of UniverseToday.com, with some editing by me.
