Synopsis

If the cosmological scale factor follows the Friedmann equation of general relativity then it can be shown that the dynamics of the universe is similar to that of a tipping pencil. Moreover, a cosmogenesis scenario can be developed if the uncertainty principle is incorporated into that dynamics.

In summary, we will briefly discuss a physicist's qualitative answer to Heidegger鈥檚 question 鈥淲hy is there something rather than nothing?鈥�
