Milky Way and Andromeda to merge

I just finished a BBC article titled Hubble times galaxy pileup

In about 4 billion years the Milky Way will collide with our neighboring galaxy Andromeda. And 2 billion years later there will only be one galaxy.  Scientific study is a curious occupation.  Scientists are discussing events that will happen in 4 to 6 billion years.   The article is full of interesting information and this curiously amusing reassurance:

Our Sun’s position will be disturbed but the star and its planets are in little danger of being destroyed.

I suppose that is true….but in 4 billion years the sun will be a red giant, Mercury and Venus will have been consumed by the Sun and the Earth will be so close to the Sun that it will have no atmosphere and be unbearably hot.  But it won’t be damaged by the galaxy collision.   Go Earth.

  1. I feel like speculative science like this uses all the wrong verbs. Instead of talking about what we expect to happen or what may or might happen, it’s what WILL happen. That kind of confidence about something that may happen four billion years after we’re gone cracks me up.

    Cool to see the galaxies colliding though. 🙂

  2. I agree, and I was a bit cavalier with my use of language too. What we supposedly know scientifically changes. Just a few years ago the universe was slowing down it’s expansion, now it’s speeding up…go figure.

  3. Can I just say what a relief to uncover someone that genuinely knows what they’re discussing on the internet. You definitely understand how to bring an issue to light and make it important. More people must look at this and understand this side of the story. I can’t believe you aren’t more popular since you surely have the gift. payday loans online
