Does 80 million light years mean 80 million years ago? If the star is moving away from us fast...
- Cthulhu_ 9y agoI think so; while it is moving away from us, 80 million years ago it exploded and sent its light our way. Because it's moving away from us, the light is stretched out a bit, causing red shift, allowing us to have a good idea of distance / time. I don't know how far the remains have traveled from us since then though.
