You shouldn't be afraid of science. Accepting the reality of nature makes life more exciting and even more precious.

[The writers of the holy books] did not even know the earth revolves around the sun. Why are we listening?

As a scientist, I don't believe anything. Science shouldn't use the word belief. There are things more likely and less likely. Science can say nothing with absolute certainty.

Now, almost one hundred years later, it is difficult to fully appreciate how much our picture of the universe has changed in the span of a single human lifetime. As far as the scientific community in 1917 was concerned, the universe was static and eternal, and consisted of a one single galaxy, our Milky Way, surrounded by vast, infinite, dark, and empty space. This is, after all, what you would guess by looking up at the night sky with your eyes, or with a small telescope, and at the time there was little reason to suspect otherwise.

There is a maxim about the universe which I always tell my students: That which is not explicitly forbidden is guaranteed to occur.

For the record: Quantum mechanics does not deny the existence of objective reality. Nor does it imply that mere thoughts can change external events. Effects still require causes, so if you want to change the universe, you need to act on it.

When a person's religious beliefs cause him to deny the evidence of science, or for whom public policy morphs into a battle with the devil, shouldn't that be a subject for discussion and debate?
