I do enjoy communicating with Clif. I emailed the following to him:
I didn’t read this, but the headline is fascinating…. and maybe all we need to know…
To which he responded:
So there are three interesting things about this article:
1. The age of the universe is 13.7 billion years since the Big Bang. This galaxy is 13.3 billion years since the big bang.
2. The only reason we can see this galaxy is because of a gravitational lens effect of nearby galaxies theorized by Einstein. The lens magnifies the galaxy to the point we can see it.
3. As a young galaxy it’s quite a bit smaller than the Milky Way (600 light years across vs. 150,000 light years across)
