Ori­gin of the uni­verse

EARTH and life sci­ence is one of the wealthy fields of sci­ence that pro­vide a gen­eral back­ground for the un­der­stand­ing of Earth Sci­ence and Bi­ol­ogy. It presents the his­tory of the Earth through ge­o­logic time. It dis­cusses the earth’s struc­ture, com­po­si­tion and pro­cesses. Is­sues, con­cerns and prob­lems per­tain­ing to nat­u­ral haz­ards are also in­cluded.

It also deals with the ba­sic prin­ci­ples and pro­cesses in the study of bi­ol­ogy. It cov­ers life pro­cesses and in­ter­ac­tions at the cel­lu­lar, or­gan­ism, pop­u­la­tion, and ecosys­tem lev­els. This is in­cluded and is given much high­light and em­pha­sis in Se­nior High School of the K-12 cur­ricu­lum.

Of its wide scope and range, to­day in this ar­ti­cle, the ex­pla­na­tion on how the uni­verse orig­i­nated will be re­vis­ited. Per­haps, since it had been over two mil­lion years ago, mil­len­ni­als to­day do not care much as to how things hap­pened be­cause it is al­ready there when they were born, too later than their par­ents were born. The uni­verse will sound a nor­mal lo­ca­tion or body of land with wa­ter and vice versa where we co­ex­ist.

Be­cause it is over 2 mil­lion years ago, we may al­ready for­got how our uni­verse came to be, thus, a re­fresher from time to time would be help­ful. I also be­lieve that if al­ways, we look back to where we come from, we can al­ways thrive on where we will be. In go­ing back to our roots, we will be able to ap­pre­ci­ate how sim­ple life was, and how un­com­pli­cated the sit­u­a­tions were; and that what makes life com­pli­cated right now be­cause we sim­ply for­got how it was be­fore.

The most pop­u­lar the­ory of our uni­verse’s ori­gin cen­ters on a cos­mic cat­a­clysm un­matched in all of

his­tory – the Big Bang. This the­ory was born of the ob­ser­va­tion that other gal­ax­ies are mov­ing away from our own at great speed, in all di­rec­tions, as if they had all been pro­pelled by an an­cient ex­plo­sive force.

What is the Big Bang The­ory? Be­fore the Big Bang, sci­en­tists be­lieve the en­tire vast­ness of the ob­serv­able uni­verse, in­clud­ing all of its mat­ter and ra­di­a­tion, was com­pressed into a hot, dense mass just a few mil­lime­ters across. This nearly in­com­pre­hen­si­ble state is the­o­rized to have ex­isted for just a frac­tion of the first sec­ond of time. Big bang pro­po­nents sug­gest that some 10 bil­lion to 20 bil­lion years ago, a mas­sive blast al­lowed all the uni­verse’s known mat­ter and en­ergy – even space and time them­selves – to spring from some an­cient and un­known type of en­ergy.

The the­ory main­tains that, in the in­stant – a tril­lion-tril­lionth of a sec­ond – after the Big Bang, the uni­verse ex­panded with in­com­pre­hen­si­ble speed from its peb­ble-size ori­gin to as­tro­nom­i­cal scope. Ex­pan­sion has ap­par­ently con­tin­ued, but much more slowly, over the en­su­ing bil­lions of years. Sci­en­tists can­not be sure ex­actly how the uni­verse evolved after the big bang. Many be­lieve that as time passed and mat­ter cooled, more di­verse kinds of atoms be­gan to form, and they even­tu­ally con­densed into the stars and gal­ax­ies of our present uni­verse.

The Big Bang The­ory leaves sev­eral ma­jor ques­tions unan­swered. One is the orig­i­nal cause of the Big Bang it­self. Sev­eral an­swers have been pro­posed to ad­dress this fun­da­men­tal ques­tion, but none has been proven – and even ad­e­quately test­ing them has proven to be a for­mi­da­ble chal­lenge. (
