What exactly is the energy of the String?

Question

I'm not quite sure how to phrase this. Strings are thought to be multi-dimensional fields of energy, right? Is it a valid question to ask what "makes up" this energy? What sort of energy is it? Does it have a source (big bang) ?

Answer 1

First, iaw super string theory, stings are not multi-dimensional; they are one dimensional, but operate in an 11-dimensional space-time. In fact, they are infinitely thin (don't ask) vibrating strings of energy one Plank length (1.6X10^-33 cm) long.

To give you an idea just how small a Plank length is, check this out:

"If the size of your fingernail were enlarged to the size of the universe, the Planck Length would be the size of a fingernail." [See source.]

According to "The Elegant Universe," cited by another answerer, how strings show up to us in our 4-D space depends solely on the vibration frequency of the strings. Quantum physics specifies that energy is proportional to frequency; so the higher vibration rates represent the higher energies in a string.

Depending on the frequency of each string, a string can appear as a weak, strong, electro-magnetic, or gravitational force. Or, again depending on its frequency, it can be any one of a dozen or so particles or quanta like: muons, quarks, and others I can't recall right now.

There are actually four string theories, which is an embarassment to the physics world. There should be but one theory to explain the universe. Ed Witten, arguably the brightest physicist in the world, came up with M-theory, which shows that the four string theories are the same theory, but from different points of view.

It's kind of like looking at a car hit a fire hydrant directly or, alternatively, through a rear-view mirror. Things would look different depending how you looked at the collision, mirror or directly, but it still would be the same car running into the same fire hydrant. Two points of view, but the same physics.

In the beginning, when the universe was very young (less than a second old after the big bang (ATBB)), it was made up of nothing but strings in their basic form. Then, as the universe cooled, some of these strings began to drop into our 4-D space as the forces and particles we recognize today in classical physics. I recall the first thing to drop into 4-D space was the photons (electro-magnetic force). Other forces dropped into real space later on; then the particles began to show up as the universe continued its cooling process.

Answer 2

It is the Stress and the Strain of a string. Since strings are made with fibers twisted closely together, the stress and the strain of the string is stored as potential energy. That is why strings are thought to multi dimensional fields or energy.

Answer 3

ignore string concept.this is plenty on nonsense permitting a large type of so-stated as scientists to waste an excellent type of time and money. it heavily isn't a concept besides in view that this suggests that you'll assume testable issues from it which will make or ruin the concept. smart books and cute television shows do not make a concept most suitable. What does make a concept most suitable isn't something you'll locate in string "concept". Lawrence Krauss, professor of physics and astronomy at Case Western Reserve college, has this to say: Describing string concept as "a lot ado about not something," Krauss defined what the dispute is all about. "the talk is twofold. A: Does string concept have something to do with the actual international. And B: Is it, as i favor to placed it, waiting for correct time? Is it properly worth all the hype and has it made any progression? i imagine the answer is not any. this is been really unsuccessful. it really is a concept in disaster — it hasn't extremely executed any of its significant aims as espoused two decades in the past. i'm not affirming a physicist should not be searching at this stuff. I purely imagine this is not worth of an excellent type of interest. Now, there aren't any extremely good selections, yet i am going to guarantee even as there is, anybody is going to drop string concept like a warm potato and flow onto something else. I have lined some references to a e book which will set you striaght about string concept.

Answer 4

If string theory is valid, then strings would be the absolute, most fundamental "things" in nature. To talk about what they might be made of--including energy--would imply that they are not the most fundamental constituents of nature.

"...a string is simply a string--as there is nothing more fundamental, it can't be described as being composed of any other substance."
'The Elegant Universe' (c) Brian Greene, pp 141-142

Answer 5

If the big bang is the beginning of our birth as a Universe, then all energy is derived from it. All strings, electron, protons, neutrons all atoms, molecules, etc., all things a-quiver were started by the BB. All things must be on the slow down but still workin' just fine so far.

Answer 6

No one knows. If we did, it wouldn't be a Theory anymore.

However, the energy is thought to "make matter" based on the "FREQUENCY" of the String's Vibrations.

Answer 7

you must mean the string theory.It is said that it is the smallest thing that tells in which direction the energy is moving it is the most accurate thing that says it.

Answer 8

strings arent neseccarily energy

and we dont know what the strings of energy inside subatomic particals are made of

Answer 9

I love topic like this. You guys rock!
