Big Bang is the prevailed cosmological model of the beginning of the Universe. It describes us different stages of the Universe formation. According to Big Bang model, the early stage of Universe formation has been abbreviated as Plank Era.
In Big Bang cosmology, the premature stage of Plank Era when the Universe exists as a high density and high-temperature state. After a cosmic inflation triggered the Big Bang which results in a metric expansion of this state and formed this Universe. A detailed study informed that the expansion takes place around 13.8 billion years ago.
Big Bang is not only created this Universe but also produce the appearance of some distinct phenomenon. Some of those like Comic microwave background, Primordial Gravitational Waves etc. Now an article published on Phys.Org which claimed that Scientists are now interested to find Primordial gravitational waves.
Primordial Gravitational Waves are ripples in the curvature of space-time that propagate as waves at the speed of light. A gravitational wave is important phenomena in observational astronomy. This wave first observed on February 11, 2016, by the scientist of LIGO interferometer team.
Cosmologists Carlo Baccigalupi and Francesca Perrotta explained the importance of their research. They summarized that the gravitational wave which originated just a few instants after the Big Bang. It means that it will help to find the incidence which occurred at the zero-moment when the Universe began.
For getting accurate data, Carlo Baccigalupi also gives a synopsis about the calibration procedure in their measurement. They study signal contaminants, i.e. the emissions coming from our galaxy, such as dust or gas, which can interfere with the analysis of primordial gravitational waves. Then they will eliminate polluting signals using mathematical models to the data.
For their comprehensive study, scientists have a plan for an observatory called The Simon observatory. According to their plan, this facility will be established in Chilean Atacama desert at an altitude of several thousand meters.
The whole facility will be constructed with an area more than 100,000 sq. Km. the area considered as one of the driest places on Earth. For their study researchers used different telescopes with a pre-existing telescope in that region used in the POLARBEAR experiment.
