Earliest presence of Hydrogen Detected
In a recent study done by the astronomers at MIT, they have successfully traced the presence of hydrogen which dates back to 180 million years ago.This experiment also explains that the universe was colder than expected.Scientists believe that this could be the earliest detection of Hydrogen gas.
Scientists believe that the state of Hydrogen traced can be only at the time of their initial contact with the first ever formed stars.The stars that formed for the first time should have interacted with these hydrogen gases.The result was that hydrogen could start absorbing background radiation which was instrumental in detecting the Hydrogen gases in the form of radio waves.These findings reveal that the universe might have been 2 times colder than previously expected.The temperature could be as much as 3 kelvins or -454 degrees Fahrenheit.
Scientists detected the presence of Hydrogen gases using EDGES(Experiment to detect global EoR signature).A small ground-based antenna in Western Austrailia.This instrument was to detect radio waves emitted from universe's history as Epoch of Reionization(EoR).
Prior to the stars, the universe should have been abandoned in the dark with hydrogen its most abundant element and was virtually invisible.Scientists believe that the energy from the first formed stars should have altered the energy states of the Hydrogen Atom.
