There are a growing number of atheists and skeptics who think that quantum mechanics proves that something could pop into existence out of nothing, or that uncaused events could happen. This would obviously refute the causal principle. Oddly, these skeptics don't seem to realize that the moment you refute the causal principle it's impossible to do science. Also, William Lane Craig and Doug Geivett explain that in quantum physics there are different interpretations of physics in the quantum level. In fact, the scientist who think that quantum physics refutes the law of causality are in the minority.
