The Universe: The Birth of The Universe (The Universe Part 1)

Where is the center of the universe? | Live Science

 

               The race of this universe began about 13.7 billion years ago when there was a really huge explosion which led to scattering of matter into the universe. Do we really know if this is true? If yes, then how did this happen? If no, then what actually happened? Why did this happen? Was there a god behind it? 

                Science doesn't really have answers to all of this, but we are trying to know what actually happened. People like Georges Lemaitre (who proposed the big bang theory) had curiosity to that level which led to the theory of big bang. Now you already know who proposed the big bang theory, but do you really know how did it all begin? 

               It all began about 14 billion years ago when the first matter in the universe was formed along with same amount of antimatter. Then the matter then rapidly started expanding itself when many atoms (basic unit of matter) were formed, they came very closer and closer starting to attract each other (just as we know that matter pulls other particles through its gravity) until the forces were even from all sides. Until now the temperature was about 10 billion degree Celsius.

               

              This pulling led to the formation of a huge ball rather a big star. The first atoms were that of a hydrogen (the first element). These hydrogen atoms present in the star started undergoing nuclear fusion due the high temperatures to make the environment electrically stable (as hydrogen had single electron). This created a lot of energy in the form of heat and light. This was the first star ever formed in our universe. 

               This star, was a millimeter wide, comprised of billions and trillions of molecules had undergone nuclear fusion. The end products of this process was a new element - Helium. This Helium was quite heavier than Hydrogen so it sank in the star's core (the middle part). The Hydrogen continued the process but also Helium, followed by it formed another new element - Carbon. This Carbon was heavier than Helium so it further sank down. 

              Many million years passed by many new elements like iron, gold, platinum etc.. were formed. The more fusion took place the more energy was produced. But they say there is end to everything, so...... was for this star. Soon, the fuel (the elements) ran out and so by fusing with each other, the temperatures dropped. The molecules were compressed to the core. Finally, the star collapsed and exploded.This was called 'The Big Bang'.

              All of its components spread in the vast universe. Many people believe there is a god behind all these events. I am not disagreeing, as science has its explanation and mythology has its own. But I think there are things unexplained even by science and there are things beyond science. Is it true?

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
