We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.
Interpretation
What this quote means
The universe's expansion rate was incredibly precise for its development.
Stephen Hawking emphasizes the delicate balance in the conditions of the universe's expansion after the Big Bang. A minuscule change in the rate of expansion would have dramatically altered the universe's ability to form celestial structures like stars and planets, highlighting the extraordinary fine-tuning necessary for the existence of life as we know it.

It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.

The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.
