6 supercurious sounds that continue without explanation

Since the last century, the human being has developed instruments that have allowed him to strengthen senses such as sight and hearing, through video and recording or audio equipment that have served to explain many of the things we see and we hear in our environment, sometimes at unimaginable distances.

However, in the case of sounds, there are still some that for humans still do not have a logical explanation, and here we will mention six of them that they have in common that coming from that other space also largely unknown: the oceans.

1."Slow Down"

It was first recorded in 1997 and for some researchers It is an iceberg running aground, although other observers believe it could be the sound emitted by a giant squid.

The sound gradually decreases as the argo of the recording, hence the name ( slow down ).

2.Upsweep

This is an underwater sound detected in the Pacific Ocean by a sound surveillance network –SOSUS– in 1991 and whose point of origin was located somewhere halfway between Australia and South America.Some scientists believe that it is volcanic activity, but this theory has not been proven.

3.The "whistle"

In July 1997 a NOAA hydrophone (a US federal agency that studies and evaluates the condition of the atmosphere and the oceans) recorded a sound, whose origin is not It was not possible to identify.The limited information has not served to feed speculation.

4.The Bloop

That same year, 1997, NOAA recorded another unusual sound coming from the sea floor: a extremely powerful signal in ultra low frequency, recorded by several stations along the west and south coast of South America and simply called bloop, We talk to you already in Science Daily Online.

It lasted one minute and was repeated several times during the summer.Some scientists believe that it could be cracks in the polar ice, although it has not been ruled out at all that may have had an organic origin.

5.Julia

It is the name given to another sound lasting 15 seconds recorded in March 1999.

The sound was recorded along the equatorial zone of the Pacific Ocean, and there is a hypothesis that it could be the bottom of an iceberg rubbing with the seabed.

6.The whale loneliest in the world

Since 1989 the call of a whale has been recorded almost annually on a frequency, 52 Hertz, in which it is difficult I could answer another whale.It is not known to which species it belongs and in 2015 funding was sought to make an expedition and make a documentary about this specimen that could be the only one, or the last of its kind.

Here we go! 6 facts about Einstein that you surely do not know 1.Its authorship on the theory of relativity was debated The theory of relativity was full of accusations of plagiarism by German scientist David Hilbert and his supporters, because Hilbert claimed that it was he who had first discovered the theory and that Einstein had taken all the credit .In his defense, Einstein I affirm that it was Hilbert who had copied some of his documents. At the beginning it was thought that every scientist had discovered the theory by his side, but that was until it was discovered that, in fact, Hilbert had stolen some documents of Einstein without giving him any credit.

Did you know this disturbing custom of Charles Darwin?

We all know, or should know, who was Charles Darwin, the 19th century English naturalist, author of The Origin of Species (1859) and considered the main creator of the modern theory of evolution , which still originates debates and controversies in places as curious as some educational centers in the United States, which defend creationism , despite the numerous scientific evidence supporting the Thesis of this extraordinary man, who was also the owner of some disturbing customs.

Why are there so many jellyfish? And why is it bad that there are so many?

Human intervention in all Earth's ecosystems does not always entail the extinction of species, sometimes it has the opposite effect, the multiplication and expansion of a particular species, generally at the expense of others. This would be the case of jellyfish, also known as aguamalas , aguavivas and sea tears , and that have become a Annoyance for tourists who come to all spas. Anemones are one of the oldest animals that still move on the face of the Earth , where they have been present for about 700 million years, and with representation in all the seas, from the Arctic to the equatorial regions.In recent years it began to be noticed that their number was increasing, and in even more recent times it began or to be considered a real problem. Causes There are several causes that have led to this "mega outcrop" of jellyfish throughout the world, although all have the usual suspect in common : the human being.The increase in jellyfish would be linked to t...

Nymph Eco. The mythological legend behind the phenomenon

The Greeks, like many other cultures of antiquity, created myths to explain those phenomena that they found incomprehensible.One of them is the echo .How is it possible that the sound we emit repeat itself? The answer for the inhabitants of ancient Greece was the Nymph Eco .Join us to discover the mythological legend behind the phenomenon. The mythological legend of the Nymph Eco We have all marveled, especially in our childhood, hearing our voice reproduced several times in certain places.It is the echo that gives us the last word we have spoken. The echo It is an acoustic phenomenon that occurs when a wave is reflected on a surface and returns to the one that has emitted it.For the human being to perceive the echo it is necessary that certain circumstances occur.The first is that persistence must be overcome acoustics and for this the reflective surface must be separated from the source 11.34 m.for dry sounds and at least 17 meters for mu sounds The second is that it mus...
