Proposed String Theory Test, A new experiment migh test strings

Good Elf,

I cannot go down the path with you, if your white rabbit is David. We are talking about eleven dimensions.

Your questions can be answered, but you will not like it, and I will not put you through what I did when I posted the 6,000 words my friend.

So let me read what is said, because that means you will have to dig, and that is a very good problem to have welcome to my world Good Elf.

Best regards and Ciao_,

Hi Yquantum,

I count them as I see them. I don't see this one so I will look some more. Hey... I "might" throw in an extra dimension if it makes people "happy".

I am not sure if this is the World of Yquantum or Lewis Carroll... He he he!

Cheers

Hi Good Elf,

Now you know why I cannot be on this I hope, believe me I would like nothing better.

Try this, In 1994 Witten made the proposal that these 6 theories were part of one great underlying theory in 11 dimensions called M-theory, the shape of space is important for the elementary forces and the particles. It can be calculated that for the theory that we believe to be the theory of everything there need to be 11 dimensions. All these dimensions have to be closed. How can it be that our world is 11 dimensional?

Before the big bang the universe was a nugget about the plank length. After the big bang only 4 dimensions expanded while the other 7 remained curled up. They are so small that they are impossible for us to see or detect. The strings vibrate in this 7D bundle which are called Calabi-Yau spaces.

To produce new Calabi-Yau spaces space can tear and repair itself after curving in another way. Good Elf hope this gives you some insight to where I am coming from.

And you are not alone, many say if 10, 11, why not 26? You get the point but 11 works very well with (g) 11 dimensional [supergravitation]. Words cannot express the reason why, but 11 is working. [Hint], there is just one dimension you are over looking!

I only have access to the open Forum, due to moving and location! Nothing else is permitted! I am so sorry.

Good Elf,

A friend gave me something that just might help a little.

Six blind people are researching an elephant. One of the blind people feels the leg of the elephant and say that it is a tree. Another feels the trunk and say the elephant is a rope. And all the others also feel different parts of the elephant and make their suggestions. None notices that what they are researching is actually one big elephant. All six theories are part of a grander underlying theory called M-theory. Through the dualities between these theories there are actually two different aspects of distance.

Good Elf this means that the universe has a tiny diameter and a huge diameter which are physically indistinguishable. Every space-time dimension has a radius. Physics in a dimension of radius R is equivalent to physics in a space-time dimension of radius 1/R. This has to do with the fact that in radius R and in a radius 1/R the winding number and the number of vibrations of the strings exchange. This is called T-duality Good Elf. This means that both systems have the same energies which implies that they are physically equivalent. Our universe is also at the same time expanding and contracting.

String theory also shows that at high energies all elementary forces become one single force if one includes supersymmetry. This is the reason for the "super" in super string theory. M-theory could be the underlying theory that Einstein was looking for his whole life. A theory that explains everything and will grant an infinite understanding. Today in M-theory one works with higher dimensional strings called branes. A string is a 1-brane, a membrane is a 2-brane. There are also higher dimensional branes. Nobody knows how these behave. It is also possible that 0-branesexist which would be the fundamental ingredients of M-theory.

These 0-branes would be responsible for space-time. Several universes could exist. A black hole for example has enough space (T-duality)(this is what you mentioned above Good Elf) for a whole universe. Is it a little clearer now?

The big bang could not have been singular phenomena. Other universes could be created or destroyed outside our universe. So this would mean that our universe is only a part of a multiverse. These are speculations that are realistic through string theory and M-theory. It will be a major task for physicists in the 21st century to fully formulate M-theory. M-theory has the potential to bring this infinite understanding. And who knows, maybe there will even be applications o M-theory. If one looks at what the quantum theory brought during the 20. century (laser, nuclear power, computers and maybe even fusion), it is hard to imagine what M-theory might bring in the 21st century.

Watch out for the typo's, I know they are hiding like a little white rabbit in some hole. Eh! Long night ahead, watch your step this is a 'HARD HAT', area?

Best of respect and Ciao_

Hi yquantum,

Thanks for the "White Elephant" .... I think! It is the present you get when you are not getting a present. He he he!

I appreciate the input you are having right now. I get the drift of what you say. 11D not 10D may be a good thing... I will look into it. Intuitively in these cases "less is better than more" but I will have a little 'thinky" about all you have said. At work right now but I will start 'looking around" this weekend.

I have made a couple of 'typos" on the back of this "Cornflake Packet" I will endeavour to fix them. I did not try to incorporate all the variety of Branes that are possible but a Theory of Everything literally discusses "everything".... He he he! I have not said what all that "other stuff" really is yet. I am only looking for the "touchy-feely" answer not the answer that a mathematician would actually be required to give.

Will be back... soon.

Cheers

The authors of the Scientific American article are convinced that mini black holes will dissipate via Hawking radiation. However, the existence of Hawking radiation is controversial. Check out the following paper. Both abstract and full text are available at the listed URL: Adam D. Helfer, "Do black holes radiate?" Reports on Progress in Physics. Vol. 66 No. 6 (2003) pp. 943-1008 http://xxx.lanl.gov/abs/gr-qc/0304042

Hi James Blodgett,

Good Elf on Black Holes
Dern toot'in right. Stephen Hawking may be wrong but luckily all evidence of his error would be removed if "everything" iwas sucked into a black hole. Of course Stephen would say a record would be written in "strings' in the surface of the black hole entropically. Now that is a nice thought But who will read it saying ...
"Here lies the human race ...
was coming first,
but couldn't last."

good morning, gentlemen -

ok, stretching a bit here...

Recently there was a report (http://www.physorg.com/news3134.html) of microgamma ray bursts within our own atmosphere. Wouldn't it be very interesting (since, apparently there are ~50 per day - a veritable plethora of experimental fodder!) to test Drs. Hawking's and Helfer's competing hypotheses right here? Of course, the BIG "IF" being that these microbursts are mini black holes popping in and out of existence...hmmmmmmmmmmmm:huh:
