Looming galactic collision will rip open the black hole at the Milky Way's center

NBC News

The end of the Milky Way as we know it may come a few billion years ahead of schedule.

According to a new paper published Jan. 4 in the journal Monthly Notices of the Royal Astronomical Society, our home galaxy appears to be on a crash course with one of its nearest satellites, the spiral of stars known as the Large Magellanic Cloud (LMC).

This cosmic crash, modeled in lovely and terrifying detail by a team of astrophysicists at Durham University in the U.K., could begin as soon as 2 billion years from now ó roughly 2 billion to 3 billion years sooner than the long-anticipated collision between the Milky Way and its nearest cosmic neighbor, the Andromeda Galaxy. (Adjust your doomsday clocks accordingly.)

While the LMC boasts only about one-twentieth the solar mass of the Milky Way, the collision would nevertheless leave permanent scars on both galaxies, igniting once-dormant black holes, flinging stars quadrillions of miles out of orbit and staining the sky with crackling cosmic radiation.

5. Astrophysicists would note that galaxies colliding does not mean that all of the..

..stars and planets would collide with each other.

Though galaxies have huge numbers of stars and other stellar bodies in them, they are still mostly empty space. The collision will be more of a coalescence of two galaxies to form a single new one.

It could feed matter into the super massive black hole at the center of our Milky Way (Sagittarius A*, https://en.wikipedia.org/wiki/Sagittarius_A*) which could result in massive gamma ray bursts (https://en.wikipedia.org/wiki/Gamma-ray_burst) that could fry planets.

But we'll all be dead before then.

8. "they are still mostly empty space"

Exactly! A "collision" between objects would probably be relatively (at least on this grand a scale) rare. You would basically have parts of 2 nebulous entities sortof blending together.

Yup. The only way.

Trump Wil declare a galactic emergency.

13. Holy inaccurate headlines Batman!

No, the black hole will in fact not be ripped open nor will it be the end of the Milky Way.

14. I hear ya

I was constructing a reply, changing the wording, trying not to be rude or condescending, until I finally gave up. NBC posted the worst science article since Ken Hamm's most recent one. If the writer doesn't know what solar mass is or that there is no such thing as a "dormant" black hole, he's in the wrong job.
