Science is a combination of theory and experiment and the two together are how you make progress.

Scientists actively approach the door to knowledge—the boundary of the domain of what we know. We question and explore and we change our views when facts and logic force us to do so. We are confident only in what we can verify through experiments or in what we can deduce from experimentally confirmed hypotheses.

Both religions and musicals work best with energetic and committed believers. Cynicism or detachment would have destroyed the magic - something true of religion, too.

Scientific research involves going beyond the well-trodden and well-tested ideas and theories that form the core of scientific knowledge. During the time scientists are working things out, some results will be right, and others will be wrong. Over time, the right results will emerge.

Speculation and the exploration of ideas beyond what we know with certainty are what lead to progress.

Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.

When people try to use religion to address the natural world, science pushes back on it, and religion has to accommodate the results. Beliefs can be permanent, but beliefs can also be flexible. Personally, if I find out my belief is wrong, I change my mind. I think that's a good way to live.
