Andromeda’s collision course with the Milky Way

I posted a warning about the threat from Andromeda in another thread recently but here is a nice presentation.

Andromeda’s collision course with the Milky Way: This Week in Astronomy with Dave Eich

At 300Km per second!

Don’t look now, but a head-on intergalactic collision is in our distant future. From observations, astronomers know that the Andromeda Galxay (M31) — the nearest large galaxy — is moving toward our own Milky Way. Their mutual gravitational pull makes a galaxy merger inevitable, starting some 4 billion years from now.

Just something extra to add to our list of worries -- if I should live so long.

Reminds me of the story about the King who ordered his gardener to plant some trees.

"I want them planted tomorrow!" he said.

"But sire," replied the gardener, "are you aware that these trees take a hundred years to reach maturity?"

"Hmm," said the King. "In that case, plant them this afternoon!"

I guess it's the lazy person's way to travel to Andromeda without bothering to invent FTL travel!

If Andromeda wants to play Chicken, that's fine with me!
This galaxy doesn't even have a steering wheel!

Milkdromeda? Ugh, that's terrible. I suppose Andromeda Way might work, but I really hope we can find the time to come up with a better name before this happens.

Popcorn emoji. You humans like that sort of thing right? Haha, just kidding. Did you you hear about this new movie Barbie?

Yeah, we don't want our new mega-galaxy sounding like a cheesy 70's soap opera.

It's obviously an Eddorean plot...

My thoughts exactly - we need to be looking out for Kimball Kinnison and the Red lensman!

 

[Dr.Sid]

I can dodge that.

 

[Skeptical Greg]

I really laughed at the funny part..

...how it will change the view of any skygazers left on Earth

Well it’s probably time I got out of the bath in fact.

Nothing to worry about. Life will go on on this planet as if nothing were happening. The average gap between stars is that great.

This is a Stand Your Ground galaxy!
If Andromeda trespasses, we will defend ourselves!

Under colregs the Milkyway is the stand on Galaxy as Andromeda is crossing from our port side. In any case I think the milky way is both not under command and restricted in ability to manoeuvre.

A very stupid, idiotic, lying former US president was heard to say:

“I will build a wall between our galaxy and the Andromeda Galaxy, and make the Andromeda Galaxy pay for it.”

Well, let us examine the names. "Andromeda" means "thinking of man", and the Milky Way's proper Latin name is "Via Lactea" meaning, well, "milky way". To combine them we could select one word from each to name the new galaxy Androlactea, meaning "Milkman". Yes, future humanity (if it survives that long) will dwell inside a gigantic milkman. We really should have seen it coming from the start, it's so obvious a destiny.

Well, apart from having been completely extinguished for about three billion years.

That's a pessimistic view! Let's be optimists, and hope that by then our descendants will have evolved into super dinosaur robots or ocean-dwelling energy ghosts. Either way they will glow in the dark and have advanced murderpowers and super trashy slash fiction, we wouldn't even be able to comprehend it, my stars, yes! The future is bright, and very dirty.

There won't be any oceans, so we'll have to evolve into a different kind of ghost. Does seem like the smart thing to do, though. Unless ghosts can melt.
