Just by using the principle "The overall matter throughout the universe is constant"
That is certainly not true, mass is not conserved in nuclear reactions (for example).

I wouldn't rely to much on what quantum physics says, as it is still a new science.
Quantum mechanic (specifically QED) is the most highly tested theory of all time. It is generally referred to as "the jewel of physics". It's fine to be skeptical, but remove it and it will take just about everything else with it.
