The Andromeda Galaxy Just Had a Bright Gamma Ray Event

Posted by Unknown on from the alien-super-weapon dept.

First time accepted submitter SpaceMika (867804) writes "We just saw something bright in the Andromeda Galaxy, and we don't know what it was. A Gamma Ray Burst or an Ultraluminous X-Ray Object, either way it will be the closest of its type we've ever observed at just over 2 million light years away. It's the perfect distance: close enough to observe in unprecedented detail, and far enough to not kill us all."

Certainly not the flooding of the Mediterranean that was recorded in Sumerian legends and thence made it's way into Christian myths? Because while that may have destroyed one of the great empires of the day, the rest of the world didn't notice. And I assure you, while deluge myths are common among ancient coastal civilizations, they are markedly absent from most inland civilizations.

      "The event" means Jesus is on his way.

      Ironic then that it's a false alarm.

      But even if it did happen, it happened two million years ago, when mankind was little more than short walking chimps. Hard to believe Jesus made an enormous explosion in some other galaxy that would have no effect here 2 million years before being born. Or maybe you're just being funny. Hard to tell sometimes.

      In theory, all we need to do is find a black hole and look with unreasonably high resolution and sensitivity at a point slightly more than 0.5 black hole radii away from its horizon (i.e. 1.5 schwarzchild radii from the center). The black hole acts as a lens, and at that point light is deflected by 180 degrees, letting us look back at ourselves as the earth was 2d years ago, where d is the distance to the hole in lightyears. In fact, by looking even closer to the point 0.5 black hole radii away, you can get to a point where light is deflected by 540 degrees, giving us an even fainter and more distorted image of ourselves a few minutes after the second image, and so on in infinity. In practice, even the first image will be so faint that it probably won't contain even a single photon, and would be washed out by the noise in the environment of the black hole (and between us and it) even if it did. But it's a fun through experiment.

      From the Wikipedia article

      Estimating the exact rate at which GRBs occur is difficult, but for a galaxy of approximately the same size as the Milky Way, the expected rate (for long-duration GRBs) is about one burst every 100,000 to 1,000,000 years. Only a small percentage of these would be beamed towards Earth. Estimates of rate of occurrence of short-duration GRBs are even more uncertain because of the unknown degree of collimation, but are probably comparable

      So they are mostly seen very far away due to volume effects. There are far more galaxies >100 Mly away than galaxies 100 Mly away, for example.
