Antimatter Part 2

ANTIMATTER PART 2

Every particle has its own twin production ; here its gonna be very intresting . As said every particle has its own twin and we all know that our world is made of matter the air , the water , our earth and why not us .. So by twin can we understand that there is another twin universe just as our universe ? 

Even Dirac had a same thinking and why not , that all of a sudden all the antiparticles disappeared . Where did they all go ? As we all know that our universe is always in equilibrium . It means that just the way our universe is matterised there can be an antimatterised universe as well , imagine as the mirror image of our universe . 

In that world everything is gonna be just the opposite of our universe with opposite spin planets , stars , black hole etc.. But one thing is for sure that we the citizens of this universe cannot get into that place . If we even try then we are just gonna turn into pure energy thats all . If theres other life forms in those planets just as us , then even they cant enter our universe for sure . 

Next question rises is , where is such an universe ? It looks like a sci-fi story , but this may be the truth , as theres no other conclusion where all those particles all of a sudden disappeared . But where is such an universe ? Can there be a planet just as our earth ?
To answer this : there might be such an universe somewhere at the end of our universe and obviously there might be some empty space in between these two universes where it neither has matter nor antimatter keeping them apart . In case we find such a universe in future as well , its nothing of our use because nothing from this end can enter that place , else we have to build something with antimatter itself . I can just say that this is all just a story of time . At present day CERN is readily working on this project but they are successful in making only handful of antimatter .

Antimatter

                                                                             ANTIMATTER PART1

Letz get this really simple going , antimatter are anything like demons ; if we would have to compare the gods to matter . Scientifically definition of the antiparticle is that , " those particles same like the matter particles namely proton , neutron , electron etc ,. but having an opposite charge in them and having an opposite spin ". But still they maintain their magnitudes same as that of their counterparts .
Some antiparticles are :
1.Positron - antiparticle for the electron . Both have the same charge i.e. 1.6*10^-19 C . But as stated above they have opposite charges and opposite spins . One more point to note here is its rest mass energy (MeV)  - 0.510
2. Anti-proton as the name suggests are the antiparticle for the protons . They have a rest mass energy of 938.257 MeV .
3. Anti-neutron antiparticle for neutrons . Rest mass energy being 939.551 MeV
4. Anti-neutrino antiparticle for the neutrino . Here rest mass energy being 0 MeV . Here actually the neutrino dont have another antiparticle , but serve as an antiparticle for themselves . , hence they are called 'Majorana Particle'  meaning its own antiparticle. 

After the big bang theory they are said to have equal amount of antimatter and matter particle . But when an antimatter and matter come in contact with each other they annihilate with each other to release energy .  For eg. annihilation of anti-proton with proton , 

Rest energy of a proton/anti-proton = 938.257 MeV (Mega-electronvolts) (using E = mc^2) 

2 * 938.257 = 1876.514 MeV (because there are 2 particles) 

1876.514 * 10^6 = 1876514000 eV (get from MeV to eV) 

1 eV = 1.60 * 10^-19J (convert to joules using charge of an electron (because we're in electron volts)) 

So 1876514000 eV = (1876514000 * (1.60 * 10^-19)) J 

= 3.00 * 10^-10 J . 

That is just for one particle with other particle . Then imagine for millions and millions of such particles , the energy released should have killed us all now . But that dint happen because there were some extras being produced at the time of big bang theory . This is still being studied under various famous experiments conducted out at CERN  like ALPHA , AEGIS , GBAR . But this against the traditional belief , that when a particle is created simultaneously its anti particle is also generated ,.

Thank you.
