We - LIVING IN A STRANGE AND wonderful universe (WHOSE age, size, violence, and beauty require extraordinary imagination to appreciate) still discovering the fundamental laws of nature - regards science as a beautiful truth and a true scientific inquiry which has been construed in such a way as to explain the complexities of cosmological world with an engaging combination of clarity and wit of the new picture of reality that is emerging as a result.
It seems most appropriate, but, it is absolutely-absolutely false. Science has fatal limitations - filled with uncertainty, skepticism and deliberation participate in a powerfully deductive dialectic that enables us to rework our present understanding of nature -- to step back from what we think we know, re-assess our preconceived notions, and bring forth newer, more fully formed views of our Universe. However, the scientific community (who can trace the roots of modern astronomy back to the ancient Greeks. Around 340 B. C) as a whole is ignorant about it.
While the modern science is surely incomplete - it is largely based on heuristic arguments and oversimplified models. It is strange that most brilliant and eloquent scientists are not raising the issues and the majority of the current scientific community is imbued with the dogmas of the academic club and the voice of dissent conveniently ignored or ridiculed, contrary to the true spirit of scientific inquiry. Science means truth (what we now think the world is made of and how it got that way), and scientists (persons engaging in a systematic activity to acquire knowledge that describes and predicts the natural world) are proponents of the truth. But they are teaching incorrect ideas to children (upcoming scientists) in schools /colleges etc. who can work out the distances to nine different galaxies -- largely with flair and in a highly approachable fashion. One who will raise the issue will face unprecedented initial criticism. Anyone can read the book and encompass a rapid trip in a more gentle fashion from Newton through relativity to the expanding universe, the big bang, black holes, wormholes and all the traditional menagerie of the modern cosmologist and find out the truth. It is open to everyone.
GETTING A GRIP ON GRAVITY Einstein's general theory of relativity explains gravity as a distortion of space (or more precisely, space-time)
We story telling animals (who TALK ABOUT THE nature of the universe and discuss such questions as whether it has a beginning or an end) often claim that we know so much more about the universe. But we must beware of overconfidence. We have had false dawns before. At the beginning of this century, for example, it was thought that earth was a perfect sphere, but latter experimental observation of variation of value of g over the surface of earth confirmed that earth is not a perfect sphere. Today there is almost universal agreement that space itself is stretching, carrying galaxies with it, though we are experimentally trying to answer whether cosmic [expansion will] continue forever or slow to a halt, reverse itself [and] lead to a cosmic implosion. However, personally, we’re sure that the accelerated expansion began with a state of infinite compression and primeval explosion called the hot Big Bang. But will it expand forever or there is a limit beyond which the average matter density exceeds a hundredth of a billionth of a billionth of a billionth (10-29) of a gram per cubic centimeter so-called critical density (the density of the universe where the expansion of the universe is poised between eternal expansion and recollapse)... then a large enough gravitational force will permeate the cosmos to halt and reverse the expansion or the expansion and contraction are evenly balanced? We’re less sure about that because events cannot be predicted with complete accuracy but that there is always a degree of uncertainty.
The picture of standard model of the Forces of Nature (a sensible and successive quantum-mechanical description developed by 1970s physicists) is in good agreement with all the observational evidence that we have today and remains consistent with all the measured properties of matter made in our most sophisticated laboratories on Earth and observed in space with our most powerful telescopes. Nevertheless, it leaves a number of important questions unanswered like the unanswered questions given in The Hitchhiker’s Guide to the Galaxy (by Douglas Adams): Why are the strengths of the fundamental forces (electromagnetism, weak and strong forces, and gravity) are as they are? Why do the force particles have the precise masses they do? Do these forces really become unified at sufficiently high energy? If so how? Are there unobserved fundamental forces that explain other unsolved problems in physics? Why is gravity so weak? May because of hidden extra dimensions? Very likely, we are missing something important that may seem as obvious to us as the earth orbiting the sun – or perhaps as ridiculous as a tower of tortoises. Only time (whatever that may be) will tell.
