The Universe: The Formation of The Solar System (The Universe Part 2)

Milky Way Galaxy

              

              The universe is a very vast subject or a theory. We still believe in theories to know the subject, and to know a subject we need theories. 'We all are a part of the universe and universe is a part of us from the start'. The Big Bang - the first thing we wonder when we hear this is a large massive explosion releasing a large amount of heat and light. 

              The Big Bang led to the scattering of various elements and matter. A wise man once said that there is nothing which is perfect. And due to this imperfections we or this universe exists. How? The matter was not evenly distributed in the universe. Due to this matter started to attract the rest of the matter due to difference between gravitational force causing to form galaxies and stars. And one the galaxy was our milky way galaxy. 

              The milky way galaxy about 1,05,700 light years in diameter with about 400 million stars was formed about 13.5 billion years ago is where our solar system is.4.5 billion years ago almost 27,000 light years away from the center of milky was where our solar system was going to form. 

              Before the formation of the solar system, there was only a cloud of gas (mainly hydrogen and helium) and dust called solar nebula. Due to the radiations of a nearby supernova the solar nebula collapsed.

               Due to this collapse a few particles vanished away. Due to this irregularity, the gravitational forces possessed by particles were uneven. The matter again came closer and formed round shaped structures. The irregularities between the particles formed very large gaps. 

              The largest round shaped structure was formed with more amount of hydrogen and helium, which was later called The Sun. And, the rest were formed as the planets, each with different composition. The gravitational force possessed by the Sun was the highest as it had more mass than the others so, due to the centrifugal force the planets revolve around the Sun.

              Every particle rotates on its axis and revolves around a stronger force. A particles rotates on its own axis to maintain their momentum and direction as no other force (other than centripetal force) acts on it.

             The recent searches show that each galaxy in this universe has a black hole in its center. What is a black hole? What will happen if we fall into one? Why is a black hole black? Is there a white hole? Ever wondered these questions? If yes comment below 'BLACK HOLE' if you need an explanation on black holes.

Antimatter

Image
                              Matter and Antimatter were both formed in equal amounts when there was The Big Bang. Matter consists of molecules which have atoms and atoms have subatomic particles (electron, proton and neutron). Antimatter as the name suggests it is something which is against the matter. Antimatter also has molecules in which there are atoms. But, here comes the reason why they really are called antimatter . Unlike matter, antimatter has positrons (positively charged particles) instead of electrons, anti-protons instead of protons, anti-neutrons instead of neutrons. All the particles of antimatter have equal and opposite charge and mass but the difference comes in its quantum numbers.               Antimatter was found in 1964 by James Cronin and Val Fitch. This was the basic info on antimatter. Let's come to the interesting part - What if antimatter were to collided with matter? When antimatter collides with matter it forms pure energy, neutrons and Gamma radiatio

The Process of Respiration (Part - 2)

Image
              The lungs are the site for exchange of gases. Lungs are present in the chest cavity or thorax cavity.The lungs are protected by brist bone/chest bone/sternum from the front, rib cage from sides and back bone or vertebral column from back. When we breathe in our lungs expand, moving ribs outward. When we breathe out our lungs contract, moving ribs inward.               At the bottom of the lungs a structure called diaphragm is present, which helps the lungs to expand and contract properly. Not only that, they also stop lungs from damaging the stomach. When we breathe in the diaphragm moves downward and when we breathe out they move inward. The diaphragm is also called the floor of chest cavity as it is the bottom most structure of the chest cavity.               The oxygenated blood from the heart is supplied to almost all the cells by blood vessels. The end of the blood vessel is a blood cappillary, which connects to the cell. When the blood reache

The Dark Matter

Image
                   Matter, we have known this word for long. "Matter is anything that occupies space and has mass". Everything we see, we touch, we feel is in fact matter. "Energy is the ability to do work". We knew this until 1933 when Dark Matter was discovered and 1998 when Dark Energy was discovered.                                Dark matter looks like this:                                Yes, this is indeed the Dark Matter. The Dark Matter is a kind of matter that cannot radiate, absorb or reflect light. Then a question arises, then how come do we know that Dark Matter really existed? This was because as it has its own effects on things that are visible. Dark Matter is a substance which enhances the gravitational force of visible matter. It is the only reason and explanation of rotation and revolution of planets, stars, galaxies. Dark Matter is non-baryonic (meaning they do not contain visible matter) instead they have subatomic particles which are yet to be d
