Highly unlikely, since I don't think I know anyone currently in Arizona who formerly lived in Seattle. If you think so, you're welcome to check out my FR Profile page; there's a link at the bottom to my Wikipedia user page which carries additional bio.

You also, my FRiend. I'm signing off for the night (I live in upstate NY where it's currently approaching 3AM and I have to be up at 7:30).

If the galaxy even lasts another 20-40 million years.

Once our own Sun has consumed all the hydrogen fuel in its core, it too will reach the end of its life. Astronomers estimate this to be a short 7 billion years from now. For a few million years, it will expand into a red giant, puffing away its outer layers. Then it’ll collapse down into a white dwarf and slowly cool down to the background temperature of the Universe.

I’m sure you know that some other stars explode when they die. They also run out of fuel in their core, but instead of becoming a red giant, they detonate in a fraction of a second as a supernova.

So, what’s the big difference between stars like our Sun and the stars that can explode as supernovae?

Mass. That’s it.

Phobos survived a giant impact early in its history,

Or it was arc pitted when zapped from the Martian surface.

Bush’s fault!

I'll go out on a limb, and say the Chicago Cubs will win the World Series in the next 10 million years

FIFY!
