Some modern physicists think the answer is yes. However there seems to be no evidence that this is so.[size=]For those who may be interested, there is no evidence for the assertion that there are experiments showing this universe creating something. This is pure hyperbolic speculation, it is not even known what ( if anything ) has been observed. If, indeed, some form of matter appeared where there had been none, it can only have come from some form of prior existing matter.
But besides this, is it possible that the universe could have created itself and that it sustains itself in existence?. There are lots of highly speculative theories to that effect Fr. Robert Spitzer of the Magis Center of Reason and Faith has some very interesting presentations about some of these theories. You can watch them here.
Thomas Aquinas has demonstrated philosophically that only God can cause anything to exist, only he can create anything and sustain it in existence. He discusses this in the Summa Theologica, Part 1, Qs 44-45, and 103-109. You can read it for yourself.
