Description: Alien Earths | Are We Alone? Certainly, scientists can't proceed by just observing. Scientific observation needs to be directed somehow. But at the same time, if we are to "expect the unexpected", we can't allow theory to heavily influence what we observe, and what counts as significant. We need to remain open-minded, encouraging exploration of the phenomena in the style of Brewster and similar scholars of the past. Studying the universe largely unshackled from theory is not only a legitimate scientific endeavor — it's a crucial one. The tendency to describe exploratory science disparagingly as "fishing expeditions" is likely to harm scientific progress. Under-explored areas need exploring, and we can't know in advance what we will find. In the search for extraterrestrial life, scientists must be thoroughly open-minded. And this means a certain amount of encouragement for non-mainstream ideas and techniques. Examples from past science (including very recent ones) show that non-mainstream ideas can sometimes be strongly held back. Space agencies such as NASA must learn from such cases if they truly believe that, in the search for alien life, we should "expect the unexpected."
