Black Hole Blasts Neighbor Galaxy with Deadly Jet 222

Posted by ScuttleMonkey from the no-star-system-will-dare-oppose-the-emperor-now dept.
butterwise writes to mention that astronomers have, for the first time, witnessed a super-massive black hole hitting a nearby galaxy with a "death-star-like" beam of energy. The story also has a video with simulations, pictures, and explanations. "The 'death star galaxy,' as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in the wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos."

      Well, the Earth is pretty chock full of life, and if that thing aimed for us, we'd be amazingly screwed.

      Maybe its not even technologicaly and physically possible to protect yourself from something like that. At best, if there was a super high tech civilisation in that galaxy, they got their alien asses out of there. But even then, someone correct me if I'm wrong, but even if you have a ship capable of light speed, you better have had that technology LONG before the ray hit the galaxy to make it out in time.
      • if your ship was capable of doing the speed of light or even a significant portion of it then the radiation from the blackhole jet might be red-shifted enough that it would be easy to shield; instead of gamma radiation it might red-shift down to red light and not even have enough energy to power your solar cells decently.

      That would indirectly suggest that in this galaxy there was no sufficiently advanced life that would detect, and try to protect itself, or stop, said "death ray".

      Um, dude? That "death ray" has a significant scale relative to the size of a galaxy, all of it traveling at (x-rays, gamma rays) or close to (electrons) the speed of light. For one any species caught in its path wouldn't see it until it hit them, and two even if they knew about the beam it isn't clear that they could do anything about it except hide underground for thousands of years or bug out to another part of the galaxy, which itself would require faster-than-light travel. To actually redirect or shield themselves from the beam at a degree that would be visible in our telescopes would require technology on a scale that we can't even dream of.

      I find it highly odd that you would be skeptical of the existence of life arising elsewhere in the universe (which while we have no idea what exactly it takes, we know is possible because it has happened at least once), because of the apparent lack of faster than light travel (which according to our current theories is impossible) or even more miraculous feats of what amount to complete science fiction. We can't say that it could ever even be theoretically possible to be "sufficiently advanced" to pull off what you propose, much less if humanity could ever attain it.

      Have you seen the Hubble Deep Field [hubblesite.org]? That's an extremely narrow view of the sky, and it's completely stuffed with galaxies. And because this one particular galaxy has not, as far as we can tell, birthed a civilization with Q-like [wikipedia.org] powers, you're questioning whether there could be life anywhere else out there at all? That's literally the oddest form of skepticism I've ever heard.

      Unless this is just dead-pan humor. I'll admit that I have problems detecting it when done with subtlety.

        That deep field photo is humbling beyond words. It really gives you perspective on just how insignificant we are, in the philosophical grand scheme of things.

        To paraphrase Carl Sagan's Contact, if there isn't any intelligent life out there, it sure would be an awful big waste of space.
