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

The cyclic universe theory predicts no gravitational waves from the early universe.
Interpretation
What this quote means
The quote suggests that the cyclic universe theory implies the absence of certain cosmic phenomena, specifically gravitational waves, in the early universe.
In this quote, Stephen Hawking discusses a key aspect of the cyclic universe theory, which posits that the universe undergoes endless cycles of expansion and contraction. According to this theory, the conditions in the early universe differ from those predicted by other models, particularly in relation to gravitational waves, indicating that certain physical phenomena may not have occurred during its formative stages.

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.

The existence of these patterns [fractals] challenges us to study forms that Euclid leaves aside as being formless, to investigate the morphology of the amorphous. Mathematicians have disdained this challenge, however, and have increasingly chosen to flee from nature by devising theories unrelated to anything we can see or feel.
