We observed and compiled the data obtained from Wilkinson Microwave Anisotropy probe, to get a brief understanding of Microwave Radiation in the background of the universe.

This study is important because this is the only radiation we know till date which is of the same age as of the universe, i.e 13.81 billion years & hence giving it the name "First Light".

It is important to know more about the cosmos, and to find out how the universe begin, at what temperature did the giant explosion took place, how was the universe in the past and what will be its image in the future, because glow of the first light is present in all directions throughout the universe. It is special because, it is present across the globe too!!

What does it do-The entire sky is a source of microwaves in every direction and its presence can be felt when we deal with modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy and many more.

How does it work- Microwave radiation or Relic radiation is the part of the electromagnetic spectrum and its wavelength varies from 1mm to 1m and its frequency lies in the band of 300GHz to 300MHz. Heat between a source and a recipient can be transferred in three different ways: conduction, when the two are in direct contact, similar to when you touch a hot glass; convection, when the heat is exchanged by a medium, generally fluid, similar to when hot air contacts colder air; lastly, radiation, when the heat is exchanged by the means of an electromagnetic wave, which requires no medium to spread, for example, the warmth conferred by the sun’s light that travelled millions of miles through void(empty) space. This is the only radiation present in the background of the cosmos which gives us an insight about the initial and present temperature of the universe. As time passes the presence of CMB is declining and the temperature is gradually falling down. According to research when the universe was in a compact stage and all of the microwave radiation was confined within a small space its the initial temperature was 1 billion degrees or 109 K and the present temperature of the universe when the microwave is not confined and spread over a large infinite area is approximately 2.73 kelvins.So, we can say that microwave radiation is helpful in preserving the temperature of the universe.

What do you hope to achieve- After our research we got to know about the temperature cycle of the universe, the source of derivation of several factors and theories like a concrete value of Hubble constant, Baryon Density, Cold Dark Matter Density, Physical Baryon Density, Physical Dark Energy Density, Density Fluctuations, Scalar Spectral Index, Reionization Optical Depth, Curvature of the Universe, Tensor to Scalar Ratio, Running Scalar Spectral Index, the hint how the universe begin and probably how will it end, when will the temperature drop to absolute zero.
