Monsoon has been proven quite damging in Pakistan this Year of 2021.Heavey rainfalls in upper ,northern and central Pakistan has caused quite destruction and some death unfortunately. Even Capital city and other urban areas are flooded and daily life is disturbed to some extent. Southern parts are receiving rains as well but no rain showered in our city .It sounds strange specially when rains are reported from all surrounding areas.Though due to having rain around us our weather is being slightly bearable thankfully.Hope and pray that weather take right turn soon and life be easy and accessible for all inhabitants my homeland and of planet, amen.
Few days back my younger son deleted and reinstalled window ten in his laptop successfully but when he did same to mine things went wrong as i had expected .My laptop was not responding to installation at all.I was little afraid as mine is one that my eldest son had bought as his very first laptop when he got scholarship in Fast University Karachi and almost ten years ago.When he left for the Germany he handed this to me.And when he visited us in 2019 he gifted his almost new laptop to his younger brother before heading back.He told he is creating a powerful computer for himself so he does not need a laptop.He added that he does his office work on laptop provided by company.
Back to my laptop .My laptop was dead suddenly and completely during our stay in Islamabad 2018 i guess. It recovered and allowed only window seven to install within after half month run to different shops.Nobody could figure out what was the issue except graphic. Same happened few days back when my younger son tried to install window ten.I warned him that it won't work but he said i should trust him.But history repeated itself though this time a computer fixer could install window 8 after two days effort. I am glad i got it back for now.
When electricity was disappeared for two days and one night and since cloudy weather (cloudy since almost a month with no drop of rain) our solar battery was not getting charged properly hubby asked us to use it only when it is really necessary .My younger son has attached his laptop with big monitor screen which takes lots of voltage'so there was no chance to use laptop so i started to read a book bought by my younger son .It is written by Neil Degrasse Tyson an Astrophysicist with American Museum of Natural history, director of it's world famous Hayden Planetarium. Host of radio and tv show Star Talk .My younger son is huge fan of him and watches his videos on YouTube fondly as he wants to be an astrophysicist in future .
I say this for every book i choose that this one was exactly what i wanted to read .But what to do that it is true well almost. Yes i wanted to learn about life ,How it began ,It's origin and what are it's basic principles upon which it works .I don't know if i am being lazy again and want to take a panoramic look instead of zooming into day to day problems of life like normal people do such as shortage of my summer clothes as hubby was asking me week ago to go and shop few more dresses for summer but i ward off the idea and showed him two old summer dresses i found in suitcase which was placed on the closet .I put them there few years ago and forgot about them .Yes i not forget only dates but things too .It was nice surprise actually.
I said they look in better condition and may be i don't need new ones.Lets see if this works.Idea of going to market in such heat makes me dizzy.
Okay let me share what i read in the book until now. Book has more than 200 pages and i am on 50th right now.Writer begins with the beginning the Big Bang. When Fourteen billion years ago due to Still unknown reason all the space ,all the time and all the matter was contained in a volume less then one trillionth size of this dot you see at the end of this sentence . (Oh my !!!!!!!!!!!!!!!!....................)
At that point conditions were extremely Hot ,the basic Nature that collectively describes the universe were Unified.This pinpoint cosmos could only expand in what we called today the Big Bang.In 1916 Einstein's general theory of relativity gave us modern understanding of Gravity ,in which the presence of Matter and Energy Curves the Fabric of Space and Time surrounding it.In 1920 the quantum mechanics discovered and provided us modern account of all that is small,molecules ,atoms and subatomic particles .With help of these we don't reach the finish line but only can learn highlights. From the 0 time to One ten million ,trillion ,trillion trillionth of second after the beginning universe grew to one hundred billion ,trillion ,trillionths of meter across.The German physicist Max Plank after whom these unimaginably small quantities are named ,introduced the idea of quantized energy in 1900 and generally is called father of quantum mechanics.
Astrophysicists apply the tenets and tools of general relativity and quantum mechanics to different classes of problems. They say In the very beginning ,during the Planck era the large were small and we suspect that there must have been some shotgun wedding between two but vows exchanged during the ceremony and we cannot describe certainly the behavior of universe over that time. Though we expect that at the end of Planck era Gravity wriggled loose from other still unified forces of Nature ,achieving an independent identity nicely described by our current theories .As the Universe aged through 10 power 35 second ( 10 with 35 zeros ) it continued to expend diluting all concentrations of energy . What remained of the unified forces split into "electroweak" and "strong nuclear " forces.Later the " electroweak " split into electromagnetic and the "strong nuclear " split into four forces we know and love ,with with weak force controling radio active decay ,the strong force binding the atomic nucleus ,the electromegnatic force binding the molecules and gravity binding the bulk matter.
Till then A TRILLIONTHE OF SECOND HAS PASSED SINCE BEGINNING.
All the while the interplay of Matter in the form of subatomic particles ,and Energy in the form of Photons (massless vessels of light energy which are as much waves as they are particles)was incessant. Universe was hot enough for these Photons to Spontaneously convert into Matter and Antimatter particle pairs,which immediately thereafter annihilate returning their energy back to photons.The physicist Gell Mann proposed the existence of "Quarks" in 1964.Quarks are quirky beasts and have fractional charges .It always be clutching other quarks near by.Infact the force that keeps two or more together grows actually stronger the more you separate them like a rubber band snaps back ,and create a new quark.Strong theoretical evidence suggests that an episode in early universe endowed universe with remarkable asymmetry, in which particles of Matter barely outnumbered the particles of Antimatter,by about about a billion and one to a billion.That small difference would hardly get noticed amid continuous creation ,annihilation and recreation of quarks and antiquarks,Electrons and antielectrons ,and neutrinos and antineutrons. The Odd man Out had oodles opportunities to find somebody ti annihilate with,and so did everybody else.But not for long ,as the universe continued to expand and cool ,growing larger then our solar system,the temperature dropped rapidly below trillion degree kelvin.
A MILLIONTH OF A SECOND HAS PASSED SINCE THE BEGNINNG.
The tepid universe was no longer Hot enough to cook quarks,so they all grabbed dance partners,creating heavy new particles Hadrons This transition soon resulted new emergence of various particles and their combinations. Universe continued to cool ,amount of available energy dropped from spontaneous creation of basic particles.During this era ambient photons could no longer invoke energy to manufacture quark antiquark pairs.Photons that emerged from all the annihilations lost energy to ever expending universe,dropping below the threshold requried to create hadron antihadron pairs.For every billion annihilations ,leaving a billion photons in their wake ,a single Hadron survived .Those loners get to have all the fun,serving as the ultimate source of matter to create galaxies, Stars ,Planets and petunias.
Without the billion and one to a billion Imbalance between matter and antimatter ,all Mass in the Universe would have self annihilated ,leaving the Cosmos made of Photons and Nothing else.
By now ONE SECOND OF TIME HAS PASSED.
To be continued ......
Dear friends i hope i did not bore you with passages from book as i really wanted to share how universe was born ,i hope you enjoyed it instead.
See you soon ,please keep smiling and stay blessed with faith in Creator and His laws which are for our good if followed properly.
Blessings to all of you!
