What is the string theory? or Theory of everything?

Question

Plz elaborate in simple words and also suggest some sites

Answer 1

watch "the elegant universe" on pbs.

Answer 2

Ok listen up. A field is a nothingness that vibrates to allow waves. Strings are made of nothing but represent a way to express energy in a codified way. It is probably a 100 years ahead of it time, it has been said. Which leads us to the difference between a wizard and a genius. Theory of everything(toe) attempts to unite the very big (Einstein) to the very small (quantum) .. It sounds simple but it is not. There is a fundamental difference perhaps best shown in the pioneer blue shift. (Pioneer space craft is in the wrong place) A good solution was found by the Barcelona group and it seems that Small and large clocks tell time at different rates. Well maybe Super Symmetry will do it. It seems to be coming back

Answer 3

Think of a guitar string that has been tuned by stretching the string under tension across the guitar. Depending on how the string is plucked and how much tension is in the string, different musical notes will be created by the string. These musical notes could be said to be excitation modes of that guitar string under tension.

In a similar manner, in string theory, the elementary particles we observe in particle accelerators could be thought of as the "musical notes" or excitation modes of elementary strings.

In string theory, as in guitar playing, the string must be stretched under tension in order to become excited. However, the strings in string theory are floating in spacetime, they aren't tied down to a guitar. Nonetheless, they have tension. The string tension in string theory is denoted by the quantity 1/(2 p a'), where a' is pronounced "alpha prime"and is equal to the square of the string length scale.

If string theory is to be a theory of quantum gravity, then the average size of a string should be somewhere near the length scale of quantum gravity, called the Planck length, which is about 10-33 centimeters, or about a millionth of a billionth of a billionth of a billionth of a centimeter. Unfortunately, this means that strings are way too small to see by current or expected particle physics technology (or financing!!) and so string theorists must devise more clever methods to test the theory than just looking for little strings in particle experiments.

Answer 4

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that are the basis of the Standard Model of particle physics.
The basic idea behind all string theories is that the fundamental constituents of reality are strings of energy of the Planck length (10-35 m) which vibrate at specific resonant frequencies.Thus any particle should be thought of as a tiny vibrating object, rather than as a point. A key consequence of the theory is that there is no operational way to probe distances shorter than the string length.
do you understand now?

Answer 5

string theory suggests that the particles in an atom are made of vibrating loops or energy .

it has yet to be proven but it works well in unifying the forces of nature ( weak and strong nuclear, gravity, electromagnestism)

I tend to think that something like this makes sense, as all matter is nothing but the energy of the big bang slowed in motion.

Answer 6

yea i agree with the others, the theory says everything consists of infinitesimally small (even compared to subatomic particles) vibrating strings.

Answer 7

It's extremely complicated. But, the "strings" are the smallest possible unit. They're made of energy and everything would be made of them.
