how long ago did SN1987a occur, and Hmmm, probably about 14 years, but that's just my guess.

Ridiculous. It's 150,000 light years away, and we saw its first light only 14 years ago. If it happened not long before we saw it, that either means that it could only be a tiny fraction of a lightyear away, or that the light travelled instantaneously only 14 years ago. You don't believe any of that, do you? Try again.
