No, nothing political. I just thought this was cool because radio telescopes across the planet were linked together to make a planet-sized telescope to get the image. Cool, right!

Interesting. As long as it stays far away.

Everything is expanding.

It will be a long time until things start to contract again. Cycles govern the universe.

Or we could be in trouble if it is random?

I have a friend who knows these things about space. According to him in 500 million years we won't have to worry about a Black Hole destroying us. By then the Earth's magnetic Field will fail and our atmosphere and oceans will boil off, and that will pretty much end all of our worries.

I think he's wrong. I bet we go at least a billion years before we bite the big one. I got $ 100 on it. If Global Warmers can tell us things that are sure to happen long after all of us are dead, I can make bets too.

You are an optimist. I peg humanity in its adolescence right now. Some species have gone on to exist for over a billion years but I see our tribal instincts as being detrimental.

We will continue to exist without the technology

They think that all galaxies have giant black holes in the center so it's normal and most likely necessary for a galaxy to form. I just thought it was cool that they turned the entire planet into a giant telescope to get the image.

That is a lot of black holes and maybe gateways to somewhere else.

At some point technology is our only hope if either a Big Black Hole wants to eat us, or the Sun becomes a Red Giant and also wants to eat us, or the magnetic field collapses, or a Big Ole Asteroid wants to dinosaur us. We can Star Trek the heck out of here.
