General Relativity Quantum Mechanics and the new String Theory
Hey guys (and girls for that matter) I was wondering what your thoughts were on the new String Theory, General relativity and Quantum Mechanics.

Because we cannot have General Relativity and Quantum Mechanics co-exist together, we have now come up with the new String Theory. It is that everything is made up of small membranes (strings). They are like violin or Cello strings, each vibration makes a different sound or note, so for string theory, each vibration makes different 'things'. But because these 'strings' are so small, we cannot actually see them in any way, so how can we prove that the String Theory is correct (by the way if we find out that this string theory IS correct, than, we have found the UNFIED THEORY). But because we cannot do any real tests on it because it is so small, we can't actually prove it, therefore a lot of people are saying that it is not science, it is actually philosophy. I was curious on your thoughts on the matter.
P.S: On Youtube their is a great series called "The Elegant Universe" that explains all this.
Thankyou
Sebastien.

I am not 100% sure on this but I think that Quantum Mechanics may rely on String Theory and if that statement is true wouldn't the fact that they can make Quantum Computers a new and emerging field of computing wouldn't this mean that String Theory would have to be proven even if we can't see them. Anyone is invited to shoot me down as I stated I am not sure but would like all views on my reasoning or lack thereof.

No, I don't think that this is correct, people are saying that string theory is a string of energy that represents everything and basically anything in the universe, according to the different vibrations. Quantum Mechanics state that everything is ruled/governed by chance. So it isn't exactly the same as String Theory but good thought
For example in the depth of a black hole a star s crushed to HUGE amounts of force, so huge that light can't escape. But because we are not sure on which rule to use:-
1-Should we use General Relativity because The force/power of the black hole is so MASSIVE
or
2-Should we use Quantum Mechanics because at the depth of a black hole
it is so small/sub-atomic.
And when we try to put the 2 together, as I have already stated, they just don't work, they just cannot co-exist together. But if both of these (huge forces in such a small thing) do become together then their MUST BE A THEORY, which is what we cal the UNIFICATION THEORY, but no one has found it.
Now we think we may have found it, in the so called String Theory, but we can't/ there are no means for us to test it, but f it was right than we would have, in front of us the Unification theory solved! Which would make us understand so much more about the Universe and its realms. (For eg. we would understand how Black Holes work.) But once again we can't really test this, we may later in the century consider this the greatest discovery of all, or a tragic failure. I just wanted to know peoples thought on this, but good thinking!!! But I don't think that that would be right to answer your question. Sorry for the essay
Sebastien.
P.S: By the way i am kind of new to this myself, i am only 13 years of age

Great to see a young person thinking of such concepts.
Unfortunately I suppose there are not too many other 13 year olds you can discuss your ideas with.

Thanks a lot  .Yea, that's for sure! But I really don't mind discussing it with anybody, I discuss it a lot with my father  , so if anybody does have any thoughts or opinions on this topic, please do post them!! I am always glad to listen to anything that has to do with Science/ these kind of topics

I've watched the series elegant universe, but im still not sure if the string theory should be considered as science just yet... I mean there is hardly enough evidence to make it a theory... However it is still worth pursuing and maybe it will be the bridge between the two different theories

I totally agree with you!!! But it does solve the Unification problem, so... it would be nice if it was right, it just makes so much sense though, but again, if we can't prove it, then as they said, it isn't science, it's philosophy. Keep the posts coming in, love them!!

i've been reading alot of books on qquantum mechanics and the book im currently studing (due to my dad nagging me to study it and not just read it) the book the universe a biography. its a real informative book and talks about almost everything regarding the subject and beyond. Now that you mentioned your age... i'm only 14 myself.. NOw i can relax...!

Hahahah, your dad is just like mine, hahaha, always telling me to do those sort of things. I must get that book for sure, sounds very interesting!!! 
Thanks for the recommendation, i have in actually borrowed a book from my local library, that I myself is studying called: Q is for Quantum, Particle Physics from A-Z, by John Gribbin, and it basically is a kind of very good dictionary to particle physics  Nice to know that their is someone around my age that I can discuss things with, I try mentioning a word about anything that has to do with Science with my brother and sister, and they start walking away, haha
Anyway Catch you later

Also there are books like 3 roads to quantum gravity which is a book on how they relate quantum mechanics and general relativity. My dad wants me to be a lawyer...

haha, awesome! That is annoying over your dad wanting you to be a lawer, but that's okay, you, yourself knows what you really want to do  Thanks again a lot on the recommendations, i will defintely post any recommendations that I would later come across

Here's something for you to ponder...strings are the smallest definable fundamental entities that we know of, much smaller than protons, quarks, gluons, photons, or any of the other particles in the Standard Model. They are made up of pure energy, according to theory.
If they are pure energy (whatever that may be), then what is that pure energy made out of?? In effect, what are strings??
