"An alien near the star p Velorum (87 light-years away) could be watching images of Hitler opening the Olympic Games in Berlin."

Just the morning breaking of my brain! I love this stuff, thank you.

Curious, if what the universe is expanding into doesn't exist, do you see that as creation still happening? God finished from his point of view but because of time/distance the actual creation isn't done yet?

That's an interesting way to look at it-- ongoing creation from our perspective.

Couldn't agree more on the Kardashians.

One of my all-time favorite science conundrums: How do we know the distant galaxies (ex: ones that are a million light years away) are still there? Wait a million years to see if they still "shine"? But then how do we know they're still there?

By the way, CONTACT is one of my all-time favorite sci-fi movies, right up there with 2001: A Space Odyssey. The main character (Dr. Arroway) reminds me of an accessible astrophysicist we all know.

We don't know for certain those distant galaxies are still there, but given that stars live for millions and billions of years, they almost certainly still exist.

I like Dr. Arroway a lot. She was part of the inspiration for my first daughter's name.

We're always staring at ghosts of the past. (Not surprised about your Arroway comment.)
