Yes, that is true. But this is one of the mysteries for which we are very far to get any answer at all. There are other items much more manageable on short time scales (this being said, some physicists are of course working on the foundations of physics; we need to tackle all questions).
As usual with your questions, I would say we don't know. But here, it does not matter :)
