"matter cannot be created or destroyed"......really!
Please check Ur facts. I don't think that any such theory exists. Please tell ur source for this statement. I'd like to view it also. bcos in fact matter and energy are thought to be equivalent.
by the famous equation E=m.c*2.
This equation says that mass is equivalent to some certain amount of energy.If this is true then there is no theoretical limitation to assume that mass and energy r 'inter convertible'.
And this is observed in many cases also. The 'mass defect' of an atom is predicted on the basis of this equation. And there r many other such explanations. So theoretically, matter can be created out of energy or destroyed to generate energy.

Matter is created and destroyed around us every second.
Consider nuclear fission, for example -- when the nucleus divides, the masses of the fragments are LESS than the mass of the original objects. Where did the rest go? It was converted into energy. E=mc2.
Similarly, when light nuclei are combined together in a larger one (fusion reacton that powers the Sun), the resulting nucleaus is lighter. The balance of the mass becomes energy, which travels to our plane and makes life possible. Heck, we even get a sun tan from it.

No, it has been proven to be false!
In vacuum partical pairs like electrons and positrons are created (and destroyed again) all the time.
The net force due to this creation of matter and radiation can be measured (the so-called Casimir effect).
Creation of matter at the boundery of a (very small) black hole is believed to generate Hawking radiation.
In the macroscopic world however, conservation of mass can be assumed.

Yes. Matter consists of atoms which themselves consist of protons, neutrons, electrons, etc... Atomic bond is lost if all electrons of a given atom are removed from their orbitals. Remaining particles would still exist.

Yes. Its been proven because it just changes form.
