If the universe started as a point of really small (if any) size, but with a mass and energy potential of a whole universe, how come it didn't just collapse into a black hole?

Evolution has a few parts.
Perhaps you could think of random mutations as trying new things in the future.
And... That Nature can be very unforgiving of past mistakes.
Of course, there is nothing other than statistics to prevent evolution from trying the same mutation more than once.
People, of course, turn nature updside-down. So, for example, if a species is adapted to having 2 offspring a year. Over hunting can cause that to be far below replacement value.
Darwinian evolution is blind, so cannot see forward or backwards. (although there are a couple of interesting examples of species such as bats returning to the ground to forrage on islands where there are no/ few predators / compettition.)
Changes (through random mutation etc.) can be of "benefit" "disbenefit" or "neutral". Beneficial changes are more likely to make the individual "fitter" and more likely to succeed in passing the changes on to future generations. Equally, a change that is not beneficial or neutral can still be passed on, but is less likely to be and over time, the beneficial changes in a population will tend to be reinforced (by increasing the chances of survival) whereas the "negative" changes will tend to die out.
(This of course is a massive over simplification)
ok, but i understand the principals you explained here. So, as far as i understood you, you (and i) agree that we should try to focus on the future more than the past, to initialize this kind of evolutionary process in ourselves on purpose, resulting in an eventual turning around of "the backwards walking man"? Right? Sorry, English is my second language, there might be some mistakes. Tnx for giving this thought some of your time.
Exactly what do i mean? Who reallt knows? What is god is he man girl blakc white or evan mexican!
