These "ultramassive" black holes, such as the one seen above in galaxy PKS 0745-19, gives birth to new questions as to how these massive bodies are able to coexist with their host galaxy, how they form, and the how these new discoveries might alter the current theory on the evolution of the universe. For example, the researchers behind this discovery propose the question as to how these "ultramassive" black holes are able to form so quickly, as they seem to have been present since the universe was only 5% of its current age. Though more data is needed to confirm the these measurements are correct, "ultramassive" black holes may bring with it both puzzles and solutions to the formation of our universe.

Hey, Gordon. It's cool to consider the variation within black holes, but your blog left me with a few questions. Under what conditions have these "ultramassive" black holes been discovered? Are they in spiral, irregular and elliptical galaxies? Are the galaxies with "ultramassive" black holes also larger galaxies, or are these normal galaxies that contain abnormally large black holes? I would assume that these new black holes function according to the models discussed in class, where people orbiting the black hole see objects frozen at the event horizon, but maybe their additional size introduces new properties to consider. Thanks for bringing this to my attention. There are certainly some cool questions and possibilities associated with this discovery.
ReplyDeleteGordon, I found your blog really interesting to read. Tagging along to Aaron's comment above, I am left with questions about these ultramassive black holes. For one, what have researchers hypothesized as of now regarding these black holes? Also, how many of these ultramassive black holes have researchers found? Are there enough to change theories of the formation of the universe? I also wanted to include that I particularly loved reading this blog because it just goes to show how nothing can never be proven true - scientists are always discovering something new.
ReplyDeleteGordon, I found your post pretty cool to read. I have many questions though. Like what exactly do you mean by the black holes feeding habits? Because the way im thinking about it is these black holes prey on galaxies and eat them to fill their event horizon. (haha food joke, get it?) Anyways with these black supermassive black holes being present in these galaxies what time affect does it have on everything. Does feedback have anything to do with effects? Are researchers on the verge of finding out what may have happened in order for that black hole to be created.
