Yoyo, world on a string.

Long ago men believed that matter was the end all and most obvious thing and that there is nothing more to it.
Then along came few men and showed that matter was really made up of Atoms (very very minute things), which in turn was made up of protons, neutrons and what not! (Phew!).
Many scoffed at what they understood these few men as claiming that matter = discontinuous space.
Long ago men believed that space was measurable and unchangeable.
Then came along a few men (me thinks these few men had no other work than coming along) and showed that space was a relative (not uncle, aunt, bro, sis or any such relatives) idea or notion based on the observer. They showed that a straight line is actually a curve and that it is possible for parallel lines to meet (a married mans best kept secret).
These few men (yea them again) termed these as quantum mechanics (these for studying the atoms, Microcosm) and the other one (the one that describes vast space and time, in fact daring to go to the beginning itself) as general theory of relativity. They found light to be a peculiar fellow, one whose speed remained constant whether you go towards it or move away from it. This they took as constant (this is equivalent to our feeling of being present here and now, which never varies and is always constant).
These few men now wanted to marry the two so that the progeny would be able to reconcile the micro and the macro.
But alas! This was not to be.
So these few men now tried to come along and show their G-strings, oops sorry what I meant was their new theory that ultimately everything was made up of strings. Now time for some poetry or else you may go scurrying to the next blog.

In this new millennium superstring theory or simply string theory resolves the tension between general relativity and quantum mechanics. According to string theory, the marriage of the laws of the large and the small is not only happy but also inevitable. String theory has the inherent capability to show that all of the astonishing happenings in the universe-from the frenzied dance of subatomic quarks (components of protons or neutrons) to the stately dance of orbiting binary stars, from the primordial fireball of the big bang to the majestic whirl of celestial galaxies-- are reflections of one grand physical principle, one master equation.

Wow!! I never knew that I had talent for poetry also, even if it is inspired from some web site: http://www.irfi.org/articles/articles_1_50/understanding_string_theory.htm

A time arose when there were five different string theories and it could no longer be called G string theory (typo- it should be the string theory).
After much head wracking these few men came up with the eleventh dimension (did I tell you that they already had ten dimensions? While we poo’ folks still are wallowing in three).
Don’t believe me? Then see this from the same inspiring source (link) above.

EXTRA DIMENSIONS:
It is taken for granted that our universe has three spatial (length, width and height) dimensions. In formulating the general theory of relativity Einstein showed time is another dimension. According to general relativity space and time communicate the gravitational force through their curvature. Special theory of relativity is Einstein's laws of space and time in the absence of gravity. In 1919 Theodor Kaluza, a Polish mathematician suggested that the universe might have more than the three spatial dimensions. For example, a garden hose viewed from a long distance looks like a one-dimensional object. When magnified (when looked closely), a second dimension-one that is in the shape of a circle and is curled around the house-becomes visible. The direction along the length of the hose is long, extended, and easily visible. The direction circling around the thickness of the hose is short, "curled up," and harder to see. Hence spatial dimensions are of two types. They can be large, extended, and therefore directly evident, or they can be small, curled up, and much more difficult to detect. In the case of the garden hose, the "curled-up" dimension encircling the thickness of the hose is detected either going closer the hose or using a pair of binoculars from a distance. If the garden hose is as thin as a hair or a capillary, then its curled-up dimension is more difficult to detect.

Kaluza proposed that the spatial fabric of the universe might possess more than three dimensions of everyday experience. He showed by having four spatial dimensions, Einstein's general relativity and Maxwell's electromagnetic theory can be unified into a single theory. In 1926 Oskar Klein, a Swedish mathematician showed that the spatial fabric of our universe may have both extended (the three spatial dimensions of everyday experience) and curled-up dimensions. The additional dimensions in the universe are tightly curled up into a tiny space- a space so tiny that it has so far eluded detection by even our most advanced experimental equipment.
The equations of string theory show that the universe has nine space dimensions and one time dimension. Why is it that three space and one time dimensions are large and extended while all of the others are tiny and curled up? At present there is no answer to this question.

1 dimension of time + 9 dimensions (6 hidden and 3 known) of space = 10 dimensions
The few men were praying very hard to their God of strings and finally He/She answered the prayers with M theory (No not the money theory- which we all know as the Theory of everything).
What else can "M" stands for?
According to its creator, Ed Witten(one of those few men), as quoted in the PBS documentary based on Brian Greene's book "The Elegant Universe", the "M" in M-theory "stands for magic, mystery, or matrix, according to taste." He also added, "Some cynics have occasionally suggested that M also stands for 'murky,' because our level of understanding of the theory is in fact so primitive." Then, jokingly, he said, "Maybe I shouldn't have told you that!"
Skeptics of M-theory have joked that the "M" means "Moronic" or "Moron!"
Yes yes I know you could add a few more.

So in the end these few men quietly added another dimension when no one else was looking (see my first post) to make it eleven dimensions in all.
This theory showed that they were all part of the same theory M theory, which described the cosmos made of string all weaved in a fabric in eleven dimensions.
M-theory: theory emerging from the second superstring revolution that unites the previous five superstring theories within a single overarching framework. M-theory appears to be a theory involving eleven space time dimensions, although many of its detailed properties have yet to be understood.

See how close they are to the definition of Tantra?
Tantra: Weaving.
Tantra (Sanskrit: "weave" denoting continuity
Tantra. A system of spiritual beliefs and practices said to be derived from Sanskrit Roots signifying: "body" because of its emphasis on bodily activities; "stretch" because it extends the faculties of humans; "Rope" because it secures the devotee to deity; "Harp" for the music and beauty of its philosophy; "Interior ness" for the secrecy of its doctrine; "Loom" suggesting the 2 cosmic principles, male and female, that make up the warp and woof of the woven fabric of the universe.

Remember “yat brahmaanda tat pindaanda” , eleven Rudras?
