In pertinence to my previous post. I would further that, in the case that our Universe was conceived in a big bang, the intriguing question that usually comes to mind is, what might be the state of Universe before the massive explosion that led to all creation.

The possibility that someday we understand what lies beyond our known Universe, might be an idea further from the physical limits of human existence. It lies in our inability to experience and understand an energy, that could be so finely fragmented in spaces a lot smaller than 10-35m; pure energy existing in spatial dimensions so small and higher in number than the three physical dimensions known to us, the spark of existence itself. The fragmentation of universe to such contained extremely small spaces may be to provide infinite possibilities for creation, by increasing the range of size manifestations and overall size of the Universe.
