A beautiful quote by Paul Dirac |
Many of you physics lovers would have figured out what I am gonna talk about
Yes,
The contrary to matter - Antimattter
So now let's have a brief insight about it
Antimatter:
Classical physics only allowed systems to have positive energy. But Dirac’s new theory of relativistic quantum mechanics allowed for a particle with negative energy solution, as a counterpart to the familiar positive-energy electron.
After ruling out the possibility that this particle was simply the proton – which has a hugely greater mass – Dirac predicted the existence of a new particle with the same mass of the electron but with a charge that was positive rather than negative.
It’s now understood that all particles have an equivalent antimatter particle with opposite charge and quantum spin – although some are their own antiparticle. However hardly any antimatter is seen in the observable universe, and why there should be vastly much more normal matter is one of the great unsolved problems in physics.
It was once thought that matter could neither be created nor destroyed, but we now know that energy and mass are interchangeable. When a particle collides with its antiparticle the two annihilate each other, with their mass being entirely converted into energy.
Antimatter annihilations convert the entire mass of the particles involved into energy, following Albert Einstein’s famous equation E = MC (squared).
A great deal of energy can be produced from little mass – a kilogram of matter annihilating with the same amount of antimatter will release around as much as the Tsar Bomba, the largest thermonuclear bomb ever built.
Because of this, antimatter has been touted as a possible future weapon or source of fuel – antimatter-driven propulsion is a staple of science fiction.
However, antimatter currently takes far too long to produce, and at too high an energy cost, for either weapons or fuel to be practicable. CERN claims it has taken several hundred million pounds to produce just a billionth of a gram, and that to make a gram of antimatter would take about a 100 billion years.
So what happened to all the antimatter:
The Big Bang produced equal amount of matter and antimatter but today what we see is only Matter , Where did the antimatter go ?
When matter and antimatter combine thhey cease to exist and form a photon
Then one should think why isn't the universe full of photon ?!
Well I can't answer it but the Large Hadron Collider may give us answers.
Some scientists have given an explanation on what happenned to the anti particles,which are as follows :
i. The early universe allowedd Conservation Law Violation (This makes me jealous of it)
ii. Anti particles decay faster than Normal particles
iii. They exist in equal amounts but superfast expansion of universe pulled them apart (My favorite) which means some galaxies out there could be Antimatter Galaxies
So which one are you a fan of tell me in the comments And also mention whether you think Antimatter exists in large quantities
That is it for today

ReplyDeleteDear Khushil, this is well researched and quite easy to understand by everyone. Well done and keep up the good work. I would love to read more such diverse and interesting topics.
ReplyDeleteAll the best 😊

Thank You ma'am
DeleteAn Avid fan of anti matter galaxies... Even if one is discovered, the next colonies will be with anti matter galaxies... because they will be the source of tremendous energy if brought to or nearby earth
ReplyDeleteVery Happy to know that
DeleteWhy don't you also suggest a topic
Today's topic will be Particle - Wave Duality
Thanks
