My rational understanding regarding dark matter is it is a continues force that still happening after the "big bang". It is in other words the aftermath of the big bang. According to modern science, physical space itself formed in the big bang. So base on this, dark matter is actually a formation of space that is why our universe expands. The space until now continue to form, pushing previously created space. Now question may arise," Where thus this force creating the space came from?" This question is connected to the big bang and the origin of the universe itself. They have the same answer.

This is Speculations, not Intuitive Guesswork. We still need evidence to support your explanation, and you have none with regard to the origin of the universe (nobody does). You can try this again when you're serious, but don't open this subject again unless you're ready to use more than your "intuition".
