Does Quantum Mechanics Challenge the Conservation of Matter Law?

[bobsmith76]

This comes from Paul Davies Information and the Nature of Reality but it is written by Nils Henrik Gregersen

Even more revolutionary for the concept of matter was quantum mechanics, which gave up the idea of material entities having a simple definable state at the ultimate level of matter. The uncertainty principle of quantum mechanics suggests that particles emerge out of and perish into a field of subatomic events with an ontological status that defies description in terms of simple location or duration.

the words in bold seem to violate the conservation of matter law. let me know what you think.

Not sure what you mean by conservation of matter, but energy is conserved, and in particular it is conserved when virtual particles are emitted or absorbed.
