Is it possible to even notice 30 years in 50M-year frame?

  It is when time zero begins with an explosion that outshines the whole galaxy.

  Thirty years ago, an observation was made of an event that happened 50M years ago, 50M lightyears away. Today, we are still making observations of events happening in that same location, 50M years ago. All the observations in between span 30 years here. Given that time is considered to be 'the same' everywhere in the universe, at least in reference frames with a relative velocity of 0, supposing we were there in a reference frame identical to ours, except for the location (so with the same relative velocity to the source of the observations,(obviously neglecting some minor gravitational effects caused by the different surroundings)), the observations would have spanned 30 years there as well.
