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 universe contains vastly more order than Earth-life could ever demand. All those distant galaxies, irrelevant for our existence, seem as equally well ordered as our own.

Until now, physical theories have been regarded as merely models with approximately describe the reality of nature. As the models improve, so the fit between theory and reality gets closer. Some physicists are now claiming that supergravity is the reality, that the model and the real world are in mathematically perfect accord.

In 1911 the little town of Nakhla in Egypt was the scene of one of the most remarkable events in historym when a chunk of rock fell from the sky and killed a dog. This is the only known canine fatality caused by a cosmic object. Improbably though this encounter was already, its truly extraordinary nature was revealed only decades later when scientists found that the culprit was not a common-or-garden meteorite, but a piece of the planet Mars.

Perhaps the best motivation for going to Mars is political. It is obvious that no single nation currently has either the will or the resources to do it alone, but a consortium of nations and space agencies could achieve it within 20 years.

It may seem bizarre, but in my opinion science offers a surer path to God than religion.

There is for me powerful evidence that there is something going on behind it all. . . It seems as though somebody has fine tuned nature's numbers to make the Universe. . . The impression of design is overwhelming.
