A Possible Near Miss Between Our Galaxy and the Andromeda Galaxy!

Over a decade’s worth of Hubble Space Telescope data was used to re-examine the long-held prediction that the Milky Way galaxy will collide with the Andromeda galaxy in about 4.5 billion years. The astronomers found that, based on the latest observational data from Hubble as well as the Gaia space telescope, there is only a 50-50 chance of the two galaxies colliding within the next 10 billion years. The study also found that the presence of the Large Magellanic Cloud can affect the trajectory of the Milky Way and make the collision less likely. The researchers emphasize that predicting the long-term future of galaxy interactions is highly uncertain, but the new findings challenge the previous consensus and suggest the fate of the Milky Way remains an open question.

    The entire premise of several major sci-fi series eliminated just like that

    Even if it misses they’ll still come back together after a couple more billion years

    It’s just a shift of the timetable

    Everything in the local group is gravitational bound and will merge at some point

    “Here’s one they just made up: “near miss”.
    When two planes almost collide, they call it a near miss.
    It’s a *near hit*!
    A *collision* is a near miss!
    BOOM! Look, they nearly missed. Yes, but not quite!”

    How about we simplify it a 3 body problem in galatic terms. Milky way & Andromeda & LMC

  5. Looking forward to a post here next year saying actually new data says it will and this data wasn’t quite accurate and then a post a year later say actually it probably won’t and so forth.
