There are many problems in science which are yet to be solved. But some of the problems are paramount. So I would be posting some in a series of posts (sigh.. I am too lazy to do all in a single post, but I will post a bunch of them together)
The Theory of Everything
In the last few years of life Albert Einstein was said to be profoundly interested in uniting theories of physics, aka theory of everything or something like the “Holy Grail of Physics”(I like that name). Even after 50 years of his death Physicist are racking their brains to learn whether such a theory could even exits. There are already enough problems of uniting Einstein’s theory of general relativity and theory of Quantum Mechanics. What is sought after is the reconciling four basic forces. However with recent advances in cosmology and astronomy, any such theory would now also have to accommodate dark matter, dark energy and inflationary forces. It is as if closer the physicists get to such a theory, the farther away it slips. The current mainstream theory of everything is the “superstring theory”. Recently people have started considering possibility of additional dimensions which might help in getting the “Grail”. Multiple dimensions can answer questions such as why Gravity is so much weaker than other forces. Theorizing that gravity could be leaking into our dimension from another is said to be solving some basic problems with uniting the forces.
The Creation and Fate of the Universe
Once highly controversial, the Big Bang theory of the creation of our universe has gained acceptance in recent decades. The theory, which holds that all matter exploded from a singularity, a microscopic, infinitesimally dense, single point, seeks to explain how, in an instant, nothingness exploded into everything. While the Big Bang isn’t accepted by all scientists, it has evolved over the years into the mainstream theory. But the Big Bang theory still leaves many questions unanswered. What banged? How did it bang? Why did it bang? And, leaving the realm of science and delving into philosophy and religion, did someone cause it to bang? Equally as important as the origins of our universe is the fate our universe will eventually suffer. If, as scientists believe, the universe is constantly expanding, galaxies, stars, and solar systems will continue to race away from each other, leaving dark, empty spaces in between. Or perhaps there will be a sort of second Big Bang, one in which our universe is destroyed, rather than created. One thing is certain: the question of where we came from and where we are headed has been pondered by human beings since the beginning of time. It has forever been, and will continue to be, the most important question our species can answer.
