Here's an interesting factoid:
If a pair of black holes ever hit Earth, you would literally hear them coming: not by sound, which cannot cross the vacuum of space, but by waves of gravitational force, which, as the holes approached, would knead the bones of your inner ear by a perceptible amount, producing a whine like a camera flash charging up.
So now we can HEAR our inevitable demise! Cool! :lol:

Yeah, cause it's real likely that a black hole will pass anywhere near the Sun's orbit around the galaxy... :doubt:
Still, that is interesting.
-
i could imagine the sound being so annoying that most humans would sooner kill themselves just to make it stop long before the holes get close enough to cause any real damage.
-
I imagine you'd stop hearing it... how many ppl here can hear an old tube TV when it's running with the volume off? It produces that kind of whine.

Actually the whine would slowly grow in intensity. Because of this it would be increasingly difficult to discount. Each morning you'd wake up and it'd be just a liiiittle bit louder, forcing your brain to go through the entire "ignore sound" process again.
The fact that the entire human was would be ****ing screwed would probably contribute to the sudden suicide rate increase.

Racist!
Black Holes Renamed 'Super High Gravity Locations (http://www.dailyredundancy.com/archives/1018.html)'
BRUSSELS, BELGIUM - The International Space Nomenclature Council today adopted the term 'emplacements de hauts gravité super' - or 'super high gravity locations' - as the official replacement name for black holes. Originally named in reference to the fact that light cannot escape their intense gravity, the term 'black hole' was increasingly criticized as being insensitive to African-Americans and African-Europeans.
Super High Gravity Location"We're glad the council finally took action on this issue." said Isaiah Herman, Chairman of the National African-American Coalition of People. "The unimaginable destructive power of these super high gravity locations was giving the word 'black' a negative connotation throughout the universe."
Super high gravity locations are the remnants of giant stars that collapse into a substance so dense that it has a gravitational pull that consumes all matter that comes near it. "They're the bad boys of the cosmos." says Nokidi Imsure, Professor of Astronomic Anthropology at Howyflyl University. "You would definitely want to cross the street if you saw one coming."
I guess you have to change your username then.
I notice that no one cares about offending African-Africans too. :p
Note, yes I know that this isn't a serious website. But the joke was too good to pass up.

...For a minute there, I thought that was real. It was unexpected, but not far fetched.
-
I'm sure it would be such a slow and imperceptible thing that it might not even be noticeably different except over a period of lifetimes.
-
Unless it wasn't slow. Stellar objects can travel at insane speeds when propelled by large gravitational fields like the one generated by the gigantic black hole in the middle of our galaxy. By the time a black hole came close enough for us to hear it, it would take mere minutes for it to reach us and subsequently crush us all into our component subatomic particles.

I used to wonder when I was younger whether Spiral Galaxies were the shape they were because they all had massive black holes in the centre :)

I wouldn't worry too much...the chances are slim to nil.

Besides, the gravitational tides created would have ripped the planet to pieces long before it came in audio range anyway, I would have thought.

A pair of black holes? What if only one hit Earth?
And as an aside, if anyone feels like doing some fine reading at their local library, I highly recommend the short story "How We Lost the Moon" by Paul McAuley on this very subject.

Me. So, only the children are going to realize what's going on, and all the other people will ridicule them, and too late will they figure out it's not just their imaginations? LIFE IS TURNING INTO A HORROR MOVIE!

Ya... my siblings can hear them, but my parents can't, except my mom sometimes... (she has sharp hearing!)

[Master] Do heear it? the beating of the drums? [/Master]
[music] BABY BABY BABY !!!![/music]

there are a whole lot of black holes out there, only a few have been discovered, but if you consider how long the galaxy has been arround and how many stars (of a sufficient weight) have blinked out of excistence then you get a disturbingly high number of black holes that can hit you at any godgiven second.
-
Well then there is the talk about the blackholes that form and close within a second and that are apparently happening all the time.
Still...space is big. REALLY big.

Meh..life allways WAS a horror movie..

you assume we have old tube tellies, YOU POOR PEOPLE WITH NO MONEY HAH
-
Eh?... Even ppl with flatscreens have usually been around a tube before... I believe it's cause of the 30 Hz refresh rate... No-one can hear a computer monitor tube because they are almost all at a minimum of 60 Hz... this is AFAIK; someone feel free to correct me if I'm wrong.

No they wouldn't... at first.
It's the frequency that matters more to audibility, not amplitude in itself... mechanical wave motion that can be heard as voice does not really need to be that strong in terms of actual power input. A very modest speakers can be used to propagate wave motion through air to ear. But in this case, obviously your ear would be vibrating in and itself, you could hear this voice even in perfect vacuum for the brief period of consciousness you would last there.
If the rotation cycle of the black hole pair would be in human hearing range, the alternating gravitation field would indeed cause global (or should I say, helical) mechanical wave motion in everything in the solar system, first with extremely low amplitude (and thus low audio intensity), but as the pair would close up, the intensity would magnify and you would be able to hear it.
Obviously, when it would get really up close and personal the high frequency tidal waves would cause a shattering mechanical wave motion generated by ripples in space and time that make the matter contract and squeeze with so much amplitude that it would practically first disintegrate the solar system, then heat the powder to extremely high temperatures, melt the molecules, destroy the atoms and who knows, perhaps even the protons. :mad2:
So if the rotation frequency was anything from 20 Hz to 20 kHz, then at some point the vibrations caused by the gravitation waves would indeed be heard, until the volume would go south-east and beyond, so to speak.
