How long will you continue to deny?

First of all, there is no star named "Arcuturus." Secondly, the notion that a giant nuclear furnace half again the m of the sun could "ascend" anywhere is ludicrous. We do know for sure that the star Arcturus was in existence 36 years ago. Third, Vega is a star even hotter than the sun, so it would be a poor choice for a "home world."
