What Does A Black Hole Sound Like?
Sept. 9, 2003: Astronomers using NASA’s Chandra X-ray Observatory have found, for the first time, sound waves from a supermassive black hole. The “note” is the deepest ever detected from any object in our Universe. The tremendous amounts of energy carried by these sound waves may solve a longstanding problem in astrophysics.
The black hole resides in the Perseus cluster of galaxies located 250 million light years from Earth. In 2002, astronomers obtained a deep Chandra observation that shows ripples in the gas filling the cluster. These ripples are evidence for sound waves that have traveled hundreds of thousands of light years away from the cluster’s central black hole.
“The Perseus sound waves are much more than just an interesting form of black hole acoustics,” says Steve Allen, of the Institute of Astronomy and a co-investigator in the research. “These sound waves may be the key in figuring out how galaxy clusters, the largest structures in the Universe, grow.”
Uh… Light can’t escape a black hole how can sound?
You’re right. That’s what’s odd about this post
We don’t have a black hole anywhere bear our solar system, scientists barely know what they look like, but they know what they sound like? I smell bs.

Made this fairly quickly.
It’s a hot summer day & PB and Marcy are enjoying a day outside.
Marcy is thinking about making a kick ass rock band, when Bonnie can only think about their wedding kiss.

And you’re a liar
At least all of your friends are
So am I….
Many of you have probably heard of the CEO of Abercrombie and Fitch’s controversial and flat out rude comments that the company doesn’t sell XL or XXL sizes for women because they want “cool” people to wear their clothes. Well, this blogger wrote an open letter to Jeffries and included these photos of herself and what is considered a “typical” male model body type.
Some quotes from her letter:
“The only thing you’ve done through your comments (about thin being beautiful and only offering XL and XXL in your stores for men) is reinforce the unoriginal concept that fat women are social failures, valueless, and undesirable.”
“This is largely attributed to companies like yours that perpetuate the thought that fat women are not beautiful. This is inaccurate, but if someone were to look through your infamous catalog, they wouldn’t believe me.”
“P.P.S. You should know your Large t-shirt comfortably fits a size 22. You might want to work on that.”
This has to do with fashion, though perhaps not in the way this blog has so far posted. But this sort of confidence is the sort of thing that we want our choices in clothes to reflect. You should be able to wear whatever you want and feel confident - no matter what other people may say or think.
