 Dark Matter - real or fake?! you decide.


 Lets go through some facts about dark matter and then we will find if it's real or fake-

1.White substance in physics is called the substance which does not emit electromagnetic radiation (light, x-ray) or reflection sufficient so as to feel him, but its presence can be felt by its gravitational effect on ordinary matter. White matter is the key to have inspections conducted for the presence of galaxies rotating speed. The shape of the cosmic body of black matter and the Big Bang Nucleosynthesis has been a major role. The effects of black matter have also been in the spread and distribution of cosmic radiation. All these evidence suggests that the amount of substances in galaxies, galaxy cluster, and the universe is much more than the observed amount, which is primarily black material which can not be seen.



2.White material combinations are yet unknown but new fundamental particles such WIMP  and Axions, ordinary and heavy neutrino, dwarf stars and planets can be made of clouds. According to recent evidence, the structure of black material should be from the new basic particles which are called nonbaryonic dark matter.The quantity of mass of the substance is much more common than the universe. So far, the discovery of radiation density in the universe is approximately 1 hydrogen atom per cubic meter. Its about 4% energy density can be seen. About 22% is of black matter, the remaining 74% is of medium energy. Some hard-to-scratch these substances also make dark matter but its volume is very low. The discovery of this missing mass is one of the biggest unresolved mysteries of physics and cosmology.



3.Firstly Friedz Zwieski, a Swiss scientist of the California Institute of Technology, who provided evidence about the substance of the matter. They used the Viral Theorem on the group of coma galaxies and they were known to the missing spectrum. Zviski calculates the mass of the Coma galaxy group based on the speed of the galaxies of the side of the coma galaxy group. When they compared this mass to the known mass based on galaxies and their total light glow on the basis of their galaxies, they discovered that there is 400 times more mass than expected. The gravity of the galaxies appearing in this galaxy group should be very low due to such a fast orbit, these galaxies should have some more mass for their balance. This is called the Missing Mass Problem. Zwicky said on the basis of these assumptions that there should be some invisible material on the planet which is giving proper mass and gravity to this galaxy group, which is not causing the breakdown of this galaxy group.



4.Further evidence about the substance of the matter obtained from the study of the motion of galaxies. Many of these galaxies are identical, when they have a viral theorem, their total kinetic energy should be half of their total gravity energy. According to the experimental results, kinetic energy was found more than this. Taking the gravity of the visible mass of the galaxy, the speed of the stars away from the center of the galaxy was found more than the mathematical pace by the viral theorem. 



5.The galactic rotating curve orbit, which explains the rotating speed and galaxy center, cannot be explained by visible mass. Assuming that the visual matter is only a small part of the galaxy's body, it can be interpreted. Galaxies appear to be made of a round spherical substance, in which a saucer is a visible substance in the middle. Less shiny surface dwarf galaxy the white substance is an important source of information for the study.



6.Based on the results published in August 2006, the substance was found to be separate from the ordinary substance. This result is found in the study of bullet galaxy clusters made from two different galaxies, 1500 million years ago. The rotation curve of the galaxy did not get any inspection until 40 years after the inspection of Zviski in which the ratio of light and mass is different from the unit. The ratio of more light and mass shows the presence of black matter. 



7.In the beginning of the decade of 1970, Vera Rubin, a Carnegie Institute of Washington, gained some new results with the help of a new more sensitive spectrograph. According to this wonderful result, most of the stars of a horoscope galaxy orbiting the center of the galaxy at the same speed. This meant that the mass density was mostly identical from the galaxy center. It also meant that either Newton's gravity rule cannot be applied in every condition, or this galaxy is made up of more than 50% of the mass body.

Know the man behind our favorite detective Sherlock Holmes- Sir Arthur Conan Doyle.  1.We have seen many novels and movies associated with Sherlock Holmes, which were not only known in Britain but also throughout the world. It would be wonderful to know that Sherlock Holmes was not a genuine character but was a fictional character created by Arthur Conan Doyle, who touched the new zeitgeist in the field of detection. Think now, the person who gave life to the characters like Sherlock Holmes, how big a detective would be. Arthur Conan Doyle was a British writer and physicist, with many compositions including Sherlock Holmes screaming abroad. He had lived many fictional mysterious characters through his novels. 2.Sir Arthur Conan Doyle was born on 22 May 1859 in Edinburgh district of Scotland. His father's name was Charles Dial and the mother's name was Mary. Arthur's parents were married in 1855, but due to the habit of Charles's alcoholism, his family spli...

Alexander vs Porus - 7 unbelievable facts 1.When the great emperor Porus was defeated and presented before Alexander, Alexander was asked, 'What would you do with him?' Porus said, 'treat me with a king who is with another king.' It's really a good sentence, but is it true? This Greek historian wrote to make Alexander great. 2.Purusa's name is written by Greek historians 'poras'. Plutarch, who wrote history fairly, wrote that "  Emperor Puru could not stand in front of a 20,000 army. Further, the army of 3,500,000 Dhananand, the great emperor of Magadha, the world's greatest capital, was ready to welcome him, with 80,000 cavalry, 80,000 war chariots, and 70,000 destructive elephants. His fierce soldiers bite soldiers of the enemy like poultry. 3.Was Alexander a great winner? This is what is commonly known in the history books written in the history of Greece, and the West says that the world accepts it blindly. But from the per...

The Parallel Universe - described in 7 points

By
The Parallel Universe - described in 7 points  1.In 1954, the young doctoral candidate at Princeton World School, Hugh Everett III gave the idea of ​​parallel universes or parallel universes for the first time. He had said that like many other things parallel universes also can exist in our own universe and all the universe can be related to our universe. 2.Actually, our universe is connected to another universe like any other branch. All the universes are connected with each other as if our own universe is associated with everyone. Within these parallel universes, the present circumstances of our universe are as it is today, in other cosmos, there may be different situations. For example, the species which has gone extinct in our universe may have been booming in another universe. The rules of physics of a universe can be completely different from our universe or can be completely disturbed by our rules. Though this idea is baffling mind, it is still worth understanding. ...

Ballistic missile - detailed in 7 points

By
Ballistic missile - detailed in 7 points 1.In ancient times, warriors used arrows and commands besides swords. Further, if we see, the weapons used primarily in the Ramayana and Mahabharata were those who were used by a warrior to throw them on the enemies. If this is seen literally, such weapons are called missiles. These missiles are called missiles in English.  2.Thus, today's missile is the weapon that will be killed by throwing the enemy soldiers while fighting in the war. Over time, war techniques changed and the types of missiles continued to increase. But if the general classification is done then there are two types of missiles: Cruise missile and ballistic missile. 3.Ballistic Missile: If it is said in simple words that when a device with a missile is installed, then the weapon becomes a ballistic missile. When this missile is released from its place or if it is called, then it falls on its predetermined goal according to the Earth's gravitational rul...
