Scientists to unveil 12 billion-year-old signal from universe’s ‘Dark Age’: Reports

Scientists around globe have been keenly trying to find origin of universe, how it was formed, birth of new stars, and more. In this quest to unfold mysteries of universe, a team of scientists led by University of Washington, US, have recently started a journey in closing in on a signal from "dark " of universe, a signal that has been travelling through  for some 12 billion years.

Scientists to track signals from 'Dark '

After Big Bang, re is a period before first stars were born when universe was much darker. Scientists call it a Dark where re was light or light signal to track. Dark is between time of Big Bang and formation of ancient stars. Miguel Morales, Professor at University of Washington, revealed in a statement that y think properties of universe during this era h a major effect on formation of first stars and set in motion structural features of universe we observe today. He also mentioned that way matter was distributed in universe during that era h an essential role in shaping behaviour of galaxies and galactic clusters and ir distribution around .

How did Dark came into existence?

scientists believe that before universe entered  Dark , was incredibly hot and dense. It was a time when was filled with regular interactions between photons and electrons, giving universe an opaque look. However, in less than a million years after Big Bang, se interactions became rare and with that universe increasingly became dark, hence it entered into Dark which lasted for hundreds of millions of years.

What did Dark consist of?

In darkness of vast universe, neutral hydrogen atoms that did t have a charge bloomed everywhere in it. According to Professor Morales, in Dark , re was light-based signal that can be studied to learn about it. As re was visible light, Morales hopes that re is a specific signal which comes from all that neutral hydrogen. This signal has never been measured, however, it is still present in universe. But, it is difficult to detect as in 13 billion years since that signal was emitted, our universe has become a very busy place, filled with several activities from stars, galaxies and human activity, techlogical vancements which drown out signal from neutral hydrogen. However, this signal that researchers are trying to capture is an electromagnetic rio emission which has been emitted by neutral hydrogen at a wavelength of about 21 centimetres.

How are scientists tracking 12 billion-year-old Dark Signal?

According to reports, Morales and his colleagues have developed highly sophisticated methods to filter out all worldly ise and bring m closer to that signal. researchers anunced that y h filtered out electromagnetic interference from more than 21 hours of Murchison Array data in year 2019. team of scientists from University of Washington have about 3,000 hours of ditional emission data collected by rio telescope. However, researchers are trying to filter out interference and get even closer to that obscure signal from neutral hydrogen.
