Save some for later
Does anyone try to stop reading halfway through so they can save the ending for later? a bit like eating only half a chocolate bar!

I don't understand how if the supernova happened in 1987 and it is 168,000 light years from Earth, surely we would only see what happened 168,000 years ago not 31 years ago.
When you look at the sun ("you must never look at the sun": Sir Patrick Moore) apparently you are seeing the sun where it was 10 minutes earlier and not its actual position as the distance is so great it takes the light coming from the sun 10 minutes to reach us.
Ok everyone feel free to correct my ignorance.
