>>Andromeda – the galaxy headed for a catastrophic collision with our own in about four billion years –

It’s funny how hysterical science (that is, science looking for grant money) has changed Andromeda from the friendly neighbor galaxy next door to the evil galaxy coming over to destroy us.

[Jonty30]

That’s because four billion and twenty years ago, it wasn’t a threat.

Now, with just four billion years left, it’s a major threat.

so haloes happen when glowing and cooling gases collide.. Coool. Quite the celestial laboratory the ‘Old Man’ created.

[MHGinTN]

That’s ‘Ancient of Days’ to you, grasshopper.

>>Now, with just four billion years left, it’s a major threat.

...and we need a couple million taxpayer dollars to study it. NOW!

[USFRIENDINVICTORIA]

I was thinking much the same thing; then, I concluded that there’s no reason to panic for at least another ten years. Maybe fifteen.

also helps explain why the rate of star formation has slowed down.

I thought that this was attributed to coal-fired power plants, SUVs, and cow flatulence...

You realize, don't you, that you know too much for your own good...

If what we are missing had the weight of a large kangaroo, what we have found would have the weight of a small echidna.”

I always suspected kangaroos were involved with the dark matter scenario!
I will, however, keep my aardvark/dark energy correlations to myself, for the time being.

Can you hear me now?

[Ernest_at_the_Beach]

What am I looking at?

HI gas? Stay away from the beans at the luaus.

[Marine_Uncle]

Theories abound...

"It’s funny how hysterical science (that is, science looking for grant money) has changed Andromeda from the friendly neighbor galaxy next door to the evil galaxy coming over to destroy us.

There must be a Federal government program/department/agency that can be created to help save the Earth and indeed the entire galaxy from this horrible collision. And of course the needed tax increases on all all of those rich (middle class) Americans that will be needed to fund this noble effort -- a tax on everybody until the end of time. Perhaps a high speed train line can be built to take everybody to another galaxy?

[HenpeckedCon]

Don’t worry, in a billion years or so our sun will be so hot the Earth’s water and atmosphere will be burned away. I hope we have warp drive by then or we’ll be in serious trouble!!

Thanks Ernest, here’s an “extra, extra” topic for the APoD ping list members, and a multi-list topic, btw. :’)
