Do you know the impact of the cosmic microwave background on the evolution of the universe. In this article, we will discuss this strange yet beautiful phenomenon that has been a part of our universe.
Since Supernova, our Universe is full of mysteries, some mysteries have been discovered while others are yet to be found. Our early universe was very reactive. Full of phenomena like cosmic microwave background radiation which we are going to discuss today.
The early universe was dark matter until a cluster of clouds of dust and gases. These came together and started forming entities that we know today as stars and planets. The stars and planets both were formed basically through the same process and this process had its origin established as the Big Bang.
The cosmic microwave background is a part of our very early universe. Since then the expansion has continued till the date and it is believed that the process is never-ending.
Though the stars contain highly reactive elements like Hydrogen and helium, unlike planets which contain lesser reactive elements. This makes them more stable than the stars. In a star, multiple reactions take place simultaneously to keep them producing their energy spectrum. Anyways it’s time to discuss our early universe.
1. Early Universe
Our early universe was a very dark and dull-looking place which later turned out to be the universe. Many reactions took place at a simultaneous rate that led to the development of the universe.
The Big Bang Theory plays a very vital role in the formation of our universe. Our universe still consists of a lot of cosmic bodies which are yet to be discovered by us humans.
Although we humans have mostly discovered almost all crucial information that we were supposed to know. Few scientists still believe that there’s a lot more than our universe has to offer.
This keeps the study of our universe going, it’s been more than 13.8 billion years. Since the big bang yet a lot of things are happening because of it. The amount of heat and energy that were released during the Big Bang was phenomenal.
They were quite high in terms of temperature. It would be quite imaginary and superficial to even imagine the energy and heat that were present. According to scientists the Big Bang Theory took place when every high-energy particle present in the universe came together.
Due to compression and high energy, they decompressed and exploded travelling in almost omnidirectional parts.
1.01 Introduction To The Charged Particles
These particles were travelling at a very high speed, a speed that could be greater or equal to light. This led to the Big Bang Theory. The temperature during and after the big bang was severely high and also very reactive for centuries.
The particles interacted and formed various entities like stars, planets, meteors, and other cosmic entities. This kept the average temperature very high for centuries. Gradually the hot big bang became cooling again but not cool enough to completely die.
In layman’s terms, the Big Bang theory was like a combination and cluster of very highly charged reactive particles. These particles burst and spread across the universe. This is how our universe expanded. During the burst and even today lot of heat and energy were released.
These charged particles fused together and started a reaction. In order to survive and this led to even more heat generation that was released. These charged particles consisted of hydrogen and helium mainly.
The particles started reacting with each other by attracting more charged particles around them. This led to the formation of stars. The planets on the other hand were formed by the swift reactions of clouds of gas and dust. Carried by space winds that led to the formation of a comet-like entity. Later they develop into a huge cluster.
These clusters are known as planets. Like stars, even the planets have an ongoing reaction. It lets them produce their energy like electromagnetic fields and gravitational fields.
1.02 After-Effects Of Charged Particles
This leads them to stabilize themselves and keep their momentum on track. On the other hand, stars consist of way higher frequency of reactivity than planets. This leads to the higher emission of electromagnetic waves and gravitational pull. This leads them to attract and keep planets in their respective orbits.
This collection of stars and planets together is known as a galaxy. It’s not necessary for a galaxy to have the same planet or star count. In fact, the majority of galaxies formed are without planets and even deformed stars. This leads them to be classified into another type of galaxies.
Our galaxy is recognized as Milky Way. Our galaxy is of spiral barred type there are also other types of galaxies like elliptical and Irregular. The irregular galaxies are the ones that don’t have a perfect shape or star. This leads to even further classification of galaxies that I’ve already explained in another article.
However, this things leads to an increase in the complexity of this topic. That might make it difficult for you guys to remember so I won’t dive deep into that.
2. Distant Galaxies
We already learned about how our universe was formed and how it works. Now it’s time to progress forward into our discovery which is to know about distant galaxies. These are widespread in our cosmic world. Just like our galaxy Milky Way, there were also many other galaxies that were formed due to Big Bang.
These galaxies are similar to our galaxy but not the same. The galaxies are widespread across our universe. These are active due to the ongoing reactions that are going on within them.
In science, every entity that produces energy also produces a lot of heat. So even though it might be dead galaxies it still emits a lot of heat and has energy. It can be to a level that you can’t think of.
The stars and planets in these galaxies are similar to our galaxy. This means even they might have similar properties to that of our planet. They are also spherical in shape and have their own energy-producing cores which make them afloat while revolving around the orbit.
The discovery of distant galaxies became possible due to high-tech equipment which was developed by scientists and astronomers. The tools include a wide variety of telescopes and particle detectors which help scientists in discovering distant objects.
Telescopes like the Hubble space telescope and other modern telescopes helped in discovering the cosmic life that was light years away from our planet. It was observed that the distant galaxies were moving away from our galaxies, in fact even our galaxy was travelling away. This is due to the universe expanding itself.
2.01 Expanding Universe
The expanding universe has led to the travelling of galaxies light-years away. The distant galaxies are moving at a very swift rate than the ones that are nearby.
The nearby galaxies move at a slower pace due to them being closer to us. Whereas the distant ones are moving at a very fast rate. There are also several other factors and outcomes which lead to another scenario. The distant moving planets emit lights that get redshifted which makes the light that reaches her infrared.
The original ultraviolet light spectrum gets converted into infrared light spectrum till it reaches our earth. This shows how much distance and noise are present in the universe that even the light waves get filtered out till the point they reach us.
We should consider the factor that even the gravitational fields present can bend the light and change its direction and velocity. While the speed of light is finite it still can be modified and twisted by other space entities like stars and planets.
Some Distant galaxies are also believed to be existing before the formation of our galaxy Milky Way. Scientists discovered that the light emissions which used to me travelling to Earth originated way earlier than 13 billion years.
The light may not be capturable by older equipment like the Hubble space telescope there are also other powerful satellites made by other companies which help in identifying space.
2.02 Thermal Radiation
Thermal radiation also is the reason why the discrepancy in the waves might be caused by the transmission of wavelengths due to which heavy redshifting occurs and ultraviolet waves turn into infrared waves. The study of distant objects is still ongoing and it is believed to be due to the fact of the universe expansion.
Observing our solar system also helped scientists and astronomers in understanding certain characteristics which may be uniform throughout our universe.
Recently, scientists have developed telescopes that are more powerful and capture even better than the Hubble telescope. These telescopes are powerful enough and can observe and study lights of an even higher spectrum range than that of the Hubble telescope. Scientists have recently discovered that there were many errors and flaws in the older telescopes’ reading.
This current generation of telescopes helps in understanding and gathering more data and information which is then processed through various technologies like AI algorithm building and other advancements. The Quantum fluctuations that were present in the older telescopes’ readings have also been minimal with the recent readings.
2.03 Distant Galaxies
The galaxies which are far far away are also the ones that might not have orbital behaviour similar to ours. Although, the stars and the planets follow the same pattern and behaviour they might not be identical to ours.
The duration of the day and night cycle might not be the same, that is the days might be longer or shorter irrespective of our planet and solar system behaviour.
Although there is a lot of information that is yet hidden from us, this information is hidden behind dark matter. Dark matter is matter which is hidden and the light doesn’t pass or reach till there.
This dark energy consists of various materials that could provide very crucial and pivotal information about our universe and its behaviour. These dark energy particles are believed to be cold and without any reactivity and energy-producing characteristics that are present in our solar system.
It might be a matter of time before the dark matter flips around. As soon as the reactivity increases in our universe the heat and energy get released. This heat emits a lot of light which can expose the dark matter whereas the energy released due to the reactivity might end up.
Its been observed and proved that our universe is going through continuous changes and space keeps warping the objects in it. This causes the microwave frequencies to get disturbed affecting their transmission.
2.04 Few Distant Galaxies That Are Known To Humans
Scientists and Astronomers observed and discovered a lot of characteristics of new stars and galaxies through the devices like the Hubble telescope and the James Webb. The first major distant galaxy that was observed was the GN-Z11.
This galaxy was observed by the James Webb Telescope it was known as the most distant galaxy from our galaxy. The distance between the galaxies was determined by the redshift of the light radiation.
The redshift is caused due to the stretching of the light wave which leads to this estranged phenomenon. The greater the distance, the higher its redshift.
In physics and astronomy, a redshift or a positive redshift is due to the increase in the wavelength of the wave and simultaneously decrease in the frequency of photon energy of its electromagnetic radiation, in this case, the light.
There is also another phenomenon that is in contrast to the positive redshift, it is known as negative redshift. In negative redshift, there is a decrease in the wavelength of the light wave, whereas increase in its frequency of photon energy spectrum. This phenomenon is also known as blueshift.
The blueshift is used to measure up the distance between the galaxies. These two phenomena were based on Doppler’s colour-shifting effect. Due to this phenomenon not only scientists and astronomers were able to discover the distance but also other noises or a disturbance present in these wavelengths.
The noise present in these wavelengths was due to the electromagnetic radiation that comes from the planets and the stars. This is where the cosmic microwave background comes into the picture.
3. Cosmic Microwave Background Radiation
The Cosmic microwave background is a microwave that fills almost all the space in the universe. These also are an indicator and studying them helps us to picture the image of our past universe and the planets it has. Cosmic microwaves help scientists to determine the primordial state and study its characteristics. The cosmic microwave background or CMB was first discovered by the American radio astronomers Arno Penzias and Robert Wilson. Cosmic microwaves are like the traces of our old universe, they contain very crucial information about our universe’s past and also the Big Bang itself.
3.01 The Impact of the Cosmic Microwave Background On The Evolution Of The Universe
CMB helped in identifying and learning about our origin and its past. CMB to scientists and astronomers is like a fossil to an archaeologist it has all the content required to tell the story about the universe. The story of our universe and its past is all contained in this CMB. CMB is a crucial form of source of information that helped scientists to frame a picture of our universe’s past.
The discovery of CMB was done through the satellites that picked up a strange static noise. This strange static noise was present everywhere around the space. This strange static noise was later termed CMB radiation. The static noise that was developed was due to the redshifting of the wavelength. This static generated in space consists of a plethora of information about the stars, planets, and meteors.
Originally our space was orangish in colour but as the wavelengths started stretching along with the simultaneous expansion of the universe the radiation temperature started becoming cooler and hence it got its colour to what we see and observe today. This was the first time a light travelled and this first light is the light we know today as Cosmic microwave background.
The universe is still believed to be expanding at a very high pace and will be ongoing in the development cycle. Cosmic microwave background has a very high impact on not only astronomy but also physics. The discovery of cosmic microwaves helped scientists to understand the colour wavelengths that the cosmic microwave background CMB photons emits while travelling throughout space and the cosmic world.
3.02 The Discovery of CMB
The discovery of the CMB was first done in the year 1965 by two American Scientists Penzias and Wilson. The discovery of this comics phenomena was an incident and not done on purpose. The two scientists first simply observed through their radio telescope, until they observed a strange static emission that got observed in their radio telescopes. The Radio scientists first thought that It might be due to some error in the device or any interference of the radio signals in their area so they decided to carry out their study of signals somewhere else they observed a similar occurrence at every place they went.
This led them to conclude that it was not the fault of their device or any other factors but the emissions were coming from space and they were present everywhere they could find.
This led them to conclude and from that moment the cosmic microwave background was discovered and made as a concept and a subject of study and research. Cosmic microwaves were unharmed and not had any effect on them no matter the time or the weather or the season anywhere.
This even made it more obvious that the waves were indeed originating from space and the outer world itself and not Earth. The cosmic waves are believed to be all the extra material or the result of the Big Bang.
3.3 After The Big Bang
After the Big Bang, a lot of particles were scattered and remained there unchanged this led to the cosmic microwaves as we know today.
The particles are uniformly spread across the universe and can be accessed through radio telescopes. The origin of this beautiful and strange phenomenon was the Big Bang.
The Bang Bang left a lot of things after the big boom a lot of particles are left divided and scattered across the universe. The Big Bang released a lot of energy across the energy spectrum it was the hottest and the most reactive reaction that was observed in this whole space. Not only it released an immense amount of heat but also energy.
The Cosmic microwave background is the cooled and remaining or the leftover part of the same. It is powerful enough to kill to transmit and share a lot of crucial and sensitive information about our universe. Also, it is responsible for its expansion.
Today scientists and Astronomers consist of this phenomenon as some echo or some shockwave that was the aftermath of the Big Bang. It was formed after the universe was cooled down. It took a large time for the universe to cool down, presumably 300000 years.
During this time the atoms and other particles like neutrons became cooler. Also, they became less reactive and this led the light to travel across our cosmic world.
Final Note
Cosmic microwave background is a type of radiation that has been a part of our universe for a very long time and it dates a lot prior that what we live in Today. This Cosmic microwave background radiation can be observed by and radio telescope and since it’s the oldest one every device can detect it.
However, it is not visible to our human eyes because our human eyes can see only a certain spectrum, even in the night sky you can’t spot any tiny fluctuations. But through radio frequency telescopes and satellites, one can see a lot of hidden things that are a part of our universe.
These hidden things are not active nor do they have any significant meaning to it or the future. But the cosmic background tells a lot about our past, our origin. The cosmic background also helped scientists to improvise technologies and now it can be also viewed through Nasa’s cosmic explorer.
Not only the microwave portion but also other aspects of it. We humans today might think it is not any significant discovery but it’s the other way around. It means more than just an infrared wave.
