lowest in the universe? possible or not you tell me..

gravitational resonance...

Sani you are one clever motha, you know that?

imagine with me if you will, as a black hole absorbs matter it slowly expands before it is able to compact the matter into the singular point which we assume is how black holes do what they do.

this tiny amount of expansion would be very slow and virtually unnoticeable to everything but as it expands (even though it is gaining mass) the specific gravity will shrink (due to less density) which causes everything around the hole to be pulled slightly less

essentially it causes a wave uses the entire universe as a medium

i can explain further how this is possible if youd like

i can see what you mean. so the fluctuation of the gravity of the dead star is what would cause the oscillation of the wave. the only way i can see this making a perceivable and measurable sound wave is if the rate at which the black hole captures matter is so great that its size increases exponentially in a fraction of a second( pushing out like a subwoofer, except in all directions), and then the gravity of the original mass compacts it all down into the signularity in another fraction of a second. the only way that makes sense to me though is if it pushes the wave out exponentially faster than the speed of light, with the gravity of the mass staying above the speed of light, so we would still not be able to visually notice anything happening, due to the event horizon, but since the sound wave was going faster it could escape, and eventually reach earth

no no no you have it wrong. its does not expand and compact very quickly, it does it very slowly. like i said earlier the particular frequency that was measured took 3 hours (earth hours) to complete a cycle.

next thing, if you want to talk science try using less science words lol i understand what you were trying to say but it got jumbled and didnt quite make sense.

now, this wave that we recorded was not "pushed out" like a traditional sound wave would be. this wave uses the entire universe as a medium. what this means is the black hole pulls on every entity in the entire universe regardless of distance.

so, when the black hole expands ever galaxy, star etc. moves away from this particular black hole then after 1.5 hours (half of the cycle) every entity begins to get pulled back toward the black hole as its gravity returns.

imagine a wave pool. the water in this case is the fabric of space-time and the wave would be the oscillation of the black hole. obviously it is not exactly the same but it give you an idea of how i see it in my mind.

another way to think of it is using a sheet. in this case the sheet represents space-time. place some balls on the sheet spaced out. pull on the sheet at one singular point straight up. every single ball will be affected by this action, slowly let the sheet return and the balls will return to their spot (note this is opposite of what actually happens with a black hole, because pulling on the sheet represents gravity)

I'll contribute my nerdiness to this topic.

Sound waves are vibrations, and (as previously explained) sound needs a medium to travel through. Audible sound waves cannot exist in the vacuum of space, but they are still there in other forms.

Since sound waves are a vibration of the object, there are many different ways to tell in a vacuum. Gravitational waves and 'red shift' of radio waves are the biggest ones used to detect 'sound' coming from large objects in space. Believe it or not, black holes actually do radiate energy, they do not suck up everything. This radiation comes from their event horizon, not from the black hole itself.

The speed of light can never be broken, but if the object is moving in the direction that the light is traveling, the waves get slightly more bunched up and it causes the frequency of the light to rise. The opposite is also true, as it moves away the frequency becomes lower. This doesn't only happen to visible light, but to any other forms of light including radio waves, X-rays and micro waves, which can be detected with the Chandra X-ray Observatory. Most likely case is that they looked at the subtle 'red shifts' of the X-rays coming off of the black hole.

Oh, and Sani, there is roughly 5 times as much dark matter as there is visible matter, it just doesn't interact the same as visible matter, it stays floating around like a gas, so in a way you are right and wrong about it's 'sparseness.'

Interesting, but the rule does still apply to radio waves.

of course. i just had to throw that out there
