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

The Planck satellite may detect the imprint of the gravitational waves predicted by inflation. This would be quantum gravity written across the sky.
Interpretation
What this quote means
The quote discusses the potential detection of gravitational waves by the Planck satellite, suggesting a deep connection between quantum gravity and the cosmos.
In this quote, Stephen Hawking highlights the groundbreaking possibility that the Planck satellite could observe the remnants of gravitational waves, which were theorized to arise during the rapid expansion of the universe known as inflation. This signifies a profound intersection of quantum gravity and cosmological observations, suggesting that the principles of quantum physics may manifest visibly across the universe, fundamentally enhancing our understanding of the cosmos.

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.

Perhaps most ridiculous of all is the suggestion that we 'keep' our radioactive garbage for the use of our descendants. This 'solution', I think, requires an immediate poll of the next 20,000 generations.

Until now the theory of infinite series in general has been very badly grounded. One applies all the operations to infinite series as if they were finite; but is that permissible? I think not. Where is it demonstrated that one obtains the differential of an infinite series by taking the differential of each term? Nothing is easier than to give instances where this is not so.
