Earth’s Heartbeat – Mysterious sounds are generated every 26 seconds

Since the 1960s, seismologists on many continents have discovered that a mysterious pulse that appears to be timed every 26 seconds appears once. But for the past 60 years, no one has been able to figure out what this sound really is.

The “Earth’s Heart Rate” was first recorded in 1962, by John Oliver, a researcher at the Lamont-Doherty Geological Observatory, Columbia University. He discovered that it came from somewhere in the southern or equatorial Atlantic, and that the sound was more intense during the Northern Hemisphere summer months.

Then, in 1980, Gary Holcomb, a geologist with the US Geological Survey, also discovered this mysterious pulse and noted that it is stronger during a storm. But for some reason, the two researchers’ findings remained largely unknown for more than two decades, until a graduate student at the University of Colorado, Boulder, once again discovered “rhythm. heart “and decided to study about it.

Mike Ritzwoller, a seismologist at the University of Colorado, recently told Discover Magazine that as soon as they observed the data of graduate student Greg Bensen, he and researcher Nikolai Shapiro knew there were Something strange about this mysterious pulse.

They had to work, test equipment, analyze data and traces of fluctuations from every possible angle and even tune the source of the pulse to a location in the Gulf of Guinea, off the west coast of Europe. Africa.

Ritzwoller and his team even delved into the work of Oliver and Holcomb and published a study of mysterious pulses in 2006. But they were unable to explain what it really was. One hypothesis was that it was caused by waves, while another suggested that it was due to volcanic activity in the area, but both have not been proven to be correct.

Wave theory goes back to 2011, when Garrett Euler, a graduate student at the University of Washington at St. Louis, accurately identifying the source of the pulse from a part of the Gulf of Guinea called the Bight of Bonny, hypothesized that when a wave hits the shelf continent, the pressure distorts the ocean floor seismic, causing reflected pulse waveforms.

The Bight of Biafra is a bright spot off the coast of West Africa, in the easternmost part of the Gulf of Guinea.

Euler’s theory seems to be the right explanation, but not everyone is convinced by it. In 2013, Yingjie Xia, a researcher from the Institute of Geodesy and Geophysics in Wuhan, China, hypothesized that the source of the 26-second pulse was volcanic activity.

His theory suggests that the origin of the signal is close to a volcano on Sao Tome Island and that at least another location elsewhere in the world has some similarities with this theory.

But neither of the theories fully explains pulses. Why does the 26-second pulse only happen at the Bight of Bonny? Waves hit coasts around the world and there are many other areas with seismic activity, what’s so special about this place? It seems that these are answers that no one has been able to explain, but in reality, seismologists don’t seem to really care about it.

In another angle, scientists also discovered a mysterious “heartbeat” emanating from a cloud of cosmic dust. Normally, this space is not as noticeable until a telescope finds it “pulsing” with a nearby astronomical phenomenon. For this reason, the new research report concludes that objects appear to be linked. But the team of scientists is not clear how, the “heartbeat” emitted as gamma rays of dust clouds linked to the black hole located 100 light years away.

The team found this bizarre beat when analyzing the amount of data collected over 10 years of operation of the Fermi gamma-ray telescope. During that time, Fermi observed SS 433 – a small quasar – located about 15,000 light-years from the Milky Way. This SS 433 contains a star that is 30 times larger than the Sun along with a massive black hole – between 10 and 20 solar masses. Black holes and stars complete an orbit around each other every 13 days, and black holes continuously absorb matter from the giant star.

“This amount of matter collects into a giant accretion disk and slowly penetrates the black hole, like the way water goes down a sewer pipe,” said Jian Li, one of the researchers who contributed to the report. “However, a portion of the matter did not come down, but shot out in two symmetrical rays, from above and below the accretion disk.”

Researchers must continue to observe and have to conduct a number of hypothetical experiments to be able to understand this “beat”.

“The S 433 star system continues to amaze observers and theorists. It must be the right place to base our tests on its ability to generate cosmic rays as well as transmit signals near a quasar. small size “.
