Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere.It is not actually sound, and it can be detected through a radio receiver, which is an electronic device that receives radio waves and converts the information given by them to an audible form.
The physics of the propagation of the baryon waves in the early universe is fairly simple; as a result cosmologists can predict the size of the sound horizon at the time of recombination. In addition the CMB provides a measurement of this scale to high accuracy. [ 3 ]
The post This is the loudest recorded sound in the history of Earth appeared first on BGR. To call sound an important part of human life would be an understatement. It’s so important, that MIT ...
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
Videos of eerie noises erupting from the skies have recently surfaced on YouTube, sending people into a panic around the world. The video above shows a particularly frightening episode of this ...
The theory explains that the universe will expand until all matter decays and ultimately turns to light. Since nothing in the universe would have any time or distance scale associated with it, the universe becomes identical with the Big Bang, resulting in a type of Big Crunch that becomes the next Big Bang, thus perpetuating the next cycle.

Sound is one of the most important and misunderstood elements in filmmaking, and sound for sci-fi films adds another degree of difficulty. “Dune,” directed by Denis Villeneuve, boasts two ...
The horizontal axis shows frequency in Hertz. In acoustics, loudness is the subjective perception of sound pressure.More formally, it is defined as the "attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud". [1]
