Gravitational waves: once again, Einstein was REASON

The last prediction of Albert Einstein, made within the framework of the theory of relativity just a hundred years ago , has just been confirmed thanks to a detection made by LIGO (Laser Interferometer Gravitational-Wave Observatory ) In Science Daily Online we want to share with you some extraordinary information about this discovery.

Gravitational waves: once again, Einstein was REASON

In 1916 Albert Einstein predicted the existence of gravitational waves , and made a small mistake: I believe that these could never be detected by humans, due to the time and the immense space that would separate us from them.In the 80's a group of physicists and astronomers set out to contradict this statement and at the same time demonstrate Einstein's latest prediction; for this they designed an experiment that would involve the construction of a special observatory (LIGO), and the participation of more than a thousand scientists from fifteen countries.

LIGO facilities

The creators and promoters of the experiment were the scientists Kip Thorne and Ronald Drever , of Caltech, and Rainer Weiss , of the Massachusetts Institute of Technology, and it consisted of creating models and simulations of situations in the universe that could generate gravitational waves and determine which indicators could serve to prove its existence.The other step was the design and creation of LIGO, an observatory made up of two detectors located in the United States at a distance of 3,000 kilometers, and considered today as the optical instrument of largest and most accurate precision in the world (can detect infinitesimal anomalies, equivalent to one tenth of a nucleus of an atom).

Gravitational waves: once again, Einstein was REASON

LIGO came into operation in 2015 and on September 14 both detectors captured a signal that when compared to simulations could identify as the record of the passage of gravitational waves produced by the collision of two large black holes at 1.3 billion light years away.

According to the famous English physicist Stephen Hawking, it would be "a new form of look at the universe, ”which, in addition to checking Einstein's prediction, puts us in the presence of the first direct observation of the fusion of two black holes .

Einstein predicted that events of great magnitude, like the fusion of black holes, could make part of the matter become energy and travel ea through the universe in the form of gravitational waves, causing anomalies in space and time.

It is estimated that the fusion of these super black holes involved masses 36 times greater than our sun and part of that mass, equivalent to three suns, it became energy in fractions of a second, as described by Einstein's famous formula: E=mc2 , that is, energy is equal to mass times the velocity of the light squared.

The physics Alicia Sintes , of the University of the Balearic Islands and coordinator of the Spanish team that participated in this project, highlighted:

"It is a historical discovery, which opens a new era in the understanding of the cosmos."

Can you imagine it? We have detected a phenomenon that occurred when on our planet there was only life in the seas, and the most complex animals were sponges and jellyfish.It should be a source of pride for the human species.Now debates and research around this discovery will begin, and serve to understand a little better a law that we take for granted without more: that of gravity.

What do you think of yourself? Do not hesitate to share with us your opinions, and stay reading the curiosities about black holes.

The Westermarck Effect | The explanation of the Tabu of Incest

According to its definition, a "tabu" is a morally unacceptable behavior either by a society, a human group or a religion.Incest is a sexual tabu that is present in most societies.In general, taboos usually be of a food, behavioral or language-related nature.Share in Science Daily Online to know what is called Westermarck Effect, which for many is the explanation of the Tabu of Incest . Content Index The Westermarck Effect: The psychological explanation of the Tabu of Incest Although it seems strange to us, not all societies considered incest as a tabu when it came to their rulers.By believing that the origin of kings and queens was divine and in order to preserve that superior blood, in some cultures the real incest was practiced (already in our blog we have addressed Incest among the Egyptian pharaohs and incest among the kings of Hawaii, for example). Incest is a word that comes from the Latin «incestus» or «incastus», that is to say «not chaste» and is «the p...

The town where women chose to be single mothers

The fact that a woman chooses to be single mother , today, is no longer news in most of our countries.Particularly, what makes this story special and we want to include it in our space for Science Daily Online, is that most of the women of a locality in Vietnam called Loi, chose to be single mothers more than 30 years ago. In what way? Asking for a "xin with", that is, asking a man for a timely "exchange" without further obligation, with which to father a child and be able to raise him alone , thus covering the desire to be a mother (if one wishes) without having to marry, and without this also being frowned upon.The history that originated this practice has its roots during the Vietnam War, hence numerous anthropologists have approached this little corner of Southeast Asia to understand it a little better. We explain it to you. The choice of Loi women We will start by putting ourselves in context.The Vietnam War was a very long and sad conflict wi...

Yes, as you read it, the ostrich feet, like two big claws that come out, instead of the five fingers we are used to. Didn't you know this was possible? Do not worry, we were also surprised at some point, so at Science Daily Online we sat down to find out more about this Vadoma to bring you all the information you need to know about this particular African tribe. Don't forget to find out of the peculiar history of the Vadoma tribe. Content Index The Vadoma: the ostrich feet village Ectrodactyly is an alteration where the three central toes disappear to give way to two prominent claws. To begin, we have to locate ourselves geographically.

Natural green sand beaches, do you know where?

Most of us like to go to the beach, if it's summer to bathe and enjoy sunbathing and, if it's cold, to walk along the seashore.Most of our beaches are sandy golden with more or less coarse grain, even in some volcanic places black sand beaches abound, but did you know that there are many more colors? Perhaps the most surprising of all are the natural green sand beaches, do you know where they are? Join us to discover it. Natural green sand beaches The southernmost point of the US is in Hawaii and is known as "South Point." In that place we can find one of nature's most amazing phenomena, one of the few green sand beaches that exist in the world.It is the beach of «Papakolea» in the bay of Mahana.The name of the beach has nothing to do with color of its sand, but it means «plover», which is the name of the most frequent bird in that area. The natural green color comes from the olivine crystals that have gone detaching from the magma of the volc...
