Does the universe sound like Bb???

Question

I heard from my violin teacher (who is not exactly compus mentus) that the frequency of the universe as a whole would sound like Bb if it were possible to stand outside the universe with air between you. Is this a load of bollocks????

Answer 1

The only thing one could even remotely consider a resonant frequency of the universe would have to be the CMBR and it covers a wide range of frequencies.  But pushing the point to absurdity, one could take the peak wavelength of 2 mm at the temperature of 2.73 degrees Kelvin and say that IT is somehow representative of the whole universe.  That's a frequency of 150 gHz.  If anyone *needs* to know, that would be a C#32, offset (cents): 13.77.  That's 28 octaves above middle C -- way, way, WAY beyond audible range.

One also has to consider Doppler effects depending on the distance to the source of the radiation, and there is no single figure that represents this.  Yeah, it's a load of bunk.  And you can see that even theoretically, it isn't Bb.

(So now we know, at least, that Beethoven's Moonlight Sonata is cosmically harmonic.)

Edit:  Whoever is giving thumbs down to every answer that disagrees with your teacher, I would be very eager to hear his/her explanation.  If my answer can be discredited, I will cheerfully delete it and learn something interesting in the process.

Answer 2

Yeah, it is. That's total bunk.

Answer 3

Brant is correct.  Although all objects have a de Broglie wavelength.  Which implies that you CAN calculate the wavelength of the Universe (estimated).  But I guarantee you its not Bb!!

For some reason I'm taken with the idea that the Universe is actually a projection from a lower dimensional surface into a higher dimensional volume.  This might (hey wdik, I'm a crack pot) address some of the non-locality problems with the current model.  Using this idea, the question arises: are there vibrations on the surface which ARE in the range of human hearing (if they were sound waves).  Problem is that with time one of the dimensions, how you transform the waves into something describable in terms of human hearing is pretty ambiguous.

Answer 4

What you were told is a pile of horse droppings...

A. If you are here, you are within the Universe...because, by definition the Universe contains everything that is within Space.

B.) Space is a vacuum and therefore sound does not travel within it. There is/are no sounds in Space. Sounds are workable inside of a space craft which has an atmosphere that can transmit the sound waves and also permits the occupants to breathe.

C.) This is cute...How does she, or he, know that to be true?

I assume it comes from years of experience traveling outside of the Universe.

Answer 5

Tell him that's not quite correct - it actually sounds like "Stairway to Heaven".

Answer 6

Bollocks would be the kind word for it. First, there is no 'outside' to our Universe. Second, if this were true we would be able to detect such a pitch within our Universe. There are frequencies emitted from planets such as Jupiter but it is not Bb and no sound waves are detected from the Universe except static.

Bb would have a frequency of 466Hz.

Answer 7

I don't know about the universe, but a lot of electrical appliances seem to hum Bb because household current is typically 60 cycle AC.  A 60Hz pitch is a little sharper than Bb (58 Hz), but it's close.

Answer 8

The average temperature of the universe is around 2.725 K (= -270.435 = -454.783 F).

According to Wien's law, the peak frequency is at 160.2 GHz (160.2 billion cycles per second -- billion = thousand million).  This should be considered the dominant frequency of the universe.

Bb  (B flat or Si-flat or Ti-flat) is 466.164 Hz in the modern Equal Temperament scale (where each half-tone is a twelfth-root of 2 above the preceding one).  This is based on A = 440.000 Hz (a common tuning standard)

The ratio is 160.2 Ghz / 466.164 Hz = 343.66 million.

Not a match, the board goes back.

-----

Could it be an octave of Bb?

Meaning: the frequency of Bb, multiplied by a power of 2.

466.164 times 2^28 = 125.1 GHz

466.164 times 2^29 = 250.3 Ghz

160.2 Ghz is between these two, and not close enough to claim that it got lost in the rounding.

Therefore, 160.2 Ghz is not an octave of Bb.

Answer 9

accoriding to recent theory, all matter virbrates AT DIFFRENT FREQUENCIES

so no... it's a load of ****.
