We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Observations indicate that the universe is expanding at an ever-increasing rate. It will expand forever, getting emptier and darker. Although the universe doesn’t have an end, it had a beginning in the Big Bang. One might ask what is before that but the answer is that there is nowhere before the Big Bang just as there is nowhere south of the South Pole.
Interpretation
What this quote means
The universe is continuously expanding, and while it had a beginning, it does not have an end.
This quote by Stephen Hawking encapsulates the complex nature of the universe and its expansion. It highlights the unprecedented phenomena occurring in the cosmos, such as the irreversible expansion that leads to an eventual emptiness. Furthermore, it challenges our understanding of time and space by stating that asking what came before the Big Bang is meaningless, as there were no spatial dimensions in which 'before' could exist, similar to the concept that there is no place south of the South Pole. This insight invites deep philosophical reflections on existence and the universe's nature.

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.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
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.
In my opinion, there is no aspect of reality beyond the reach of the human mind.

A technical solution may be defined as one that requires a change only in the techniques of the natural sciences, demanding little or nothing in the way of change in human values or ideas of morality.

Facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome.
While I thought myself employed only in forming a nomenclature, and while I proposed to myself nothing more than to improve the chemical language, my work transformed itself by degrees, without my being able to prevent it, into a treatise upon the Elements of Chemistry.
