13.7 billion years ago? By who's reference?
Hi Cavediver,

Perhaps you can't answer a question which has been bothering me when I try to figure these things out: you say time is relative, so there is no universal timeframe. Okay, I can understand that. But it's also said that the Big Bang happened 13.7 Ga ago. If there isn't a universal timeframe, how can it be meaningful to describe the big bang as happening a certain number of years in the past?
