Oooops! I shoulda looked it up first. They don’t know the exact distance. But “Big B” is estimated to be only between 600 & 700 light years from Earth. Prolly none of us folks will be here to see how it ends up. But, then there’s Salvation in Christ, and eternal life etc. So those who belong to the Lord will indeed see the whole show; prolly from an even better viewing stand. Praise Jesus.
What if it blew up 639 years ago?................😯
