The thing about lucid dreams is that it's not like the real world where you are constrained by all sorts of things, including the laws of physics - you can do magic.

Astronauts have been stuck in low-Earth orbit, boldly going nowhere. American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that NASA's budget is too small for the job.

It is hard to resist the impression that the present structure of the universe, apparently so sensitive to minor alterations in numbers, has been rather carefully thought out...The seemingly miraculous concurrence of these numerical values must remain the most compelling evidence for cosmic design.

The Universe is not a collection of objects, but is an inseparable web of vibrating energy patterns in which no one component has reality independently from the entirety. Included in the entirety is the observer.

Wheeler hopes that we can discover, within the context of physics, a principle that will enable the universe to come into existence "of its own accord." In his search for such a theory, he remarks: "No guiding principle would seem more powerful than the requirement that it should provide the universe with a way to come into being." Wheeler likened this 'self-causing' universe to a self-excited circuit in electronics.

Is there anything science should not try to explain? Science is knowledge and knowledge is power - power to do good or evil. Sometimes ignorance is bliss.

The secret of life does not lie in its chemical basis . . . Life succeeds precisely because it evades chemical imperatives.
