The making of the universe

islam abad :DAILY QUDRAT :Modern life owes a lot to the scientific knowledge humanity has acquired in recent centuries. The capital of wisdom steadily accumulated and widely circulated since the invention of the printing press has been employed in several fields of research, from studies about the earth to life beyond the blue planet. There seems to be little doubt surrounding the contention that science, a method of learning about the world through experimentation and observation, has revolutionised the pace of change since it was adopted by scholars as the modus operandi for general enquiry.

Take, for instance, penicillin, the first antibiotic, discovered by Alexander Fleming in 1928. This drug is thought to have transformed the field of medicine. Without the discovery, claim medical researchers, humans would not be able to treat deadly diseases like bacterial meningitis, bacterial endocarditis and pneumococcal pneumonia, and fatalities in war, especially the two world wars of the twentieth century, would be much higher. In addition to health, stunning breakthroughs in information technology, transportation, industrial productivity, energy and environment, among other areas, have been taking place at breathtaking speed, largely thanks to the extensive employment of the scientific method to test puzzling phenomenon.

Since science has no boundaries, it encourages subject experts to investigate even the grandest of questions. This has allowed scientists to employ the same method used in discovering penicillin to look at the sky and question the very existence of the universe. Over the past few decades, cosmologists (scientists who study the universe), have made tremendous leaps in understanding how the universe has evolved to come to its present state. With the help of particle accelerators, astronomical observations and theoretical speculations, earthlings now have a coherent picture of what happened at the beginning of everything.

The most successful scientific effort to explain the making of the cosmos to date is the big bang theory, which the reader can explore in detail in this explainer. (There exist alternatives to the big bang theory, like the oscillating universe theory, which proposes never-ending cycles of the universe’s beginning (big bangs) and ending (big crunches), and the multiverse theory, which claims that our universe is a part of an ocean of universes, each of them having unique laws of physics).

Proposed by the Belgian astronomer Georges Lemaitre in 1927, the big bang theory argues that our universe came into existence from a very small, very hot and very dense point around 13.7 billion years ago. Expanding on that hypothesis, astronomers would later profess that the universe started expanding within the first second after it came into existence, and continues to do so today, which is causing a continuous drop in its temperatures. The cooling universe has led to the formation of protons and neutrons, created the first atoms, and spurred the formation of stars, galaxies and the solar system.
