th reader.Why speed of light ? Well, the aim of this blog is to reach the impossible by exploration and scientific fervor. Exploration never ends, knowledge never dies but Speed of Light can be achieved ....Mystery Behind the Anti-Matter !
What is antimatter? Does it indeed exist?
Can we detect the presence of antimatter?
Does your same body exist composed of antimatter?
Does dark matter contain antimatter?
How different would the two galaxies made up of antimatter and matter particles respectively look from earth?
Does antimatter have negative mass?
Is time travel possible due to existence of antimatter?
Well, it’s very interesting to know and understand the existence of exact opposite replica of every particle in this universe. In simple words, if we have an atom then we have an anti-atom also. Consider a hydrogen atom, for example; It has a nucleus and an electron revolving outside it. Now, there also exists an anti hydrogen atom, which has an anti-electron and an anti-nucleus in it. An anti-electron has a positive charge but has the mass as that of an electron.
It’s the ultra high speed collisions that create antimatter. It is very difficult to capture antimatter particles. Antimatter is created in the explosions taking place on the surface of stars and other inter-galactic collisions. Before the Big Bang took place there was absolutely no material particle which existed. It was only after this explosion that matter and antimatter particles were created in almost equal amounts. But according to theories and analysis a higher percentage of matter particles developed and remained in space.
It is possible to harness energy from the collision of matter and antimatter particles. Let us take a simple example to understand the principle and its use. Suppose we create a rocket that has an antimatter capturing cabinet. We can force the matter and antimatter particles to collide by throwing light on it obtained from the stars and sun. Through this collision we can generate energy which would help the rocket to propel forward towards its destination. In this process, high amount of energy would be generated and can be used in a controlled form. The biggest drawback is that it is very difficult and expensive to store antimatter. There are techniques to capture and store antimatter but again they require high amount of money and expertise. It is also very difficult to create antimatter artificially.
What is vacuum? Does it mean absence of particles?
Now if energy exists then a term like anti-energy should also exist. Well, the Dirac equation has a negative solution. Since it a relativistic quantum mechanical wave equation, it demands the presence of anti particles to have a proper explanation for its negative result. Therefore, the need of antimatter particles was felt. As of now, the expression for this equation is quite complex for a beginner in astronomy. It was at this point of time that Dirac proposed that vacuum is not actually an empty space but a space filled with electrons having negative energy. This would mean vacuums in universe are possessing high amount of negative energy. But this was not quite appealing to people. So absence of real particles or a state in which no particles exist is considered as a vacuum.
From the very beginning we have been studying Einstein’s famous equation E=mc2.
The equation E=mc2 is actually E2=p2c2 + m2c4
We consider the special case, when the particle is at rest. This makes momentum (p) of the particle zero and the equation reduces to E=+(mc2) or E=-mc2.
The negative sign explains the existence of antimatter.
Well, it’s antimatter all the way! Think about anti blackholes, anti ice creams or maybe anti….

It's very nice article... My mind has been recharged after reading your article...
my opinion is that everything in this universe is bound to have a mirror image wether it is the electron and the positron or those paralell universes wherein they claim the existence of multiple mirror images of our universe.....but leaving that aside ....I would like to ask you a question on which i am still speculating .......Could it be possible that our body is comprised of a delicate combination of matter and anti matter.......assuming an hypothetical situation wherein the body is considered to be a machine(car) ..(for which the fuel required for its functioning is in the form of food and other stuff) and the soul(if it exists)to be the driver which may be antimatterial in nature... the car knows that the engine is responsible for its functioning and the governing system controls the fuel flow but it is devoid of acknowledging the driver.........wat r ur views??? This might sound insanely retardic beyond help but wat the hell??
dude tell me on thing ..how do you get into this field????
