Thanks for sharing these updates, Tom. This stuff underlines how inconsequential we are in the grand scheme of the universe. Here is distant light distorted by a cluster of galaxies (!) 3.6 billion light years away. The light source is likely an order of magnitude more distant than that.

Then the article references a 13 billion (with a B!) year old star spotted in a similar manner. There's no escaping that we are in the midst of learning more about the origins and inner workings of the universe and physics than all learned in human history so far.

And the sheer math involved underlines that there simply must be other forms of intelligent life out in this vastness. Or at least that have existed over different times through the course of 13 billion years.

I can't even comprehend what football discussion boards are like in other universes. I wonder if they're posting about us!

Given that the observable universe is 46 billion light years in any direction from Earth, most of those other civilizations evolved through sports like football billions of years ago. That assumes they were able to avoid killing themselves.

A long time ago in a galaxy far far away.

A nearly inconceivable achievement.
I’m currently reading “The First Three Minutes,” by Steven Weinberg, Nobel Prize for Physics 1979, and his description of the sheer brilliance of astrophysicists is really something.

Yes, it’s the first three minutes after the Big Bang.

It’s a good book but Simon Singh’s “The Big Bang” is the one you want.

"the light you're seeing from the red objects below is generated by the black holes at the center of these early galaxies."
Can somebody please explain black holes to me? I thought that they we so massive that their gravitational pull would not allow light to escape. The above statement from the article seems to contradict that.

Material spinning around the black hole at dramatic speeds - but not dropping in as it doesn’t cross the event horizon -generates the light.
