I just got this exciting news delivered to my RSS reader:
Coming: Beta Geminorum (22 hours away)
Beta Geminorum is 33.7 light years away and only 22 hours from the outer surface of your light cone – your ever-growing sphere of potential causality – which began its expansion from Earth on September 04 1970.
You can get your own light cone updates if you are also given to flights of interstellar frivolity.
