A supermassive black hole was removed from its galaxy by a burst of gravitational radiation. Researchers state that black holes around this size and bigger can actually be ejected from their own galaxy where they were created. Some evidence suggests that not only every large galaxy houses a supermassive black hole at its core, but that a galaxy’s center of stars grows in lockstep with the mass of the black hole. I think this is very interesting because it would improve our understandings of galactic formations. I also did not know that it was possible for a galaxy to eject something from itself. I thought this because of the large amount of gravity within a galaxy which keeps everything within itself intact and inside its perimeter. This event has one problem with it. The scientists also found a strange third emission line, which leaves a big question mark on their work. I found out that an emission lines are photons reemitted in a narrow frequency range from gas that are not in their original photon source. "The strange third emission line is also narrow but bluer in color than the other narrow line." I also found this interesting because the two colors show that they may be looking at the position of two separate quasars that have similar but not identical distances. What that means is that if this is true then the thought of a recoiling black hole would not be correct. It would be devastating if the recoiling black hole was incorrect because this event would help us understand a lot of things.
