The "worm hole" suspect that: The universal that we were living now was created when the door of time was opened. In many universal, rather in this, the biggest quality of the black hole is continuously swallowing the other astronomical in the universal. Its size had also increased, and it is big enough to contain the large amount of gravity that is able to destroy everything that is in solid form: Started with absorbing its core and transform it into the source of energy, accumulating it, and finally broke out of its "shell". It then release its power, forming another "worm hole", the door of time had been opened. When the power had used out, it will then stop releasing. At the same time, the door of time will be closed. After a long time of evolution the "high-intelligent seed", will form the universal that we were living today. On another side, which is the "worm hole" will turn into the normal astronomical in the universal, and this was the reason why we can never find the mid-point of the universal.
