The most interesting part of the interview for me was when Blundell was speaking about searching for other solar systems and how scientists are limited by their own imaginations. She recalled that at the time, researchers were only searching for solar systems exactly like ours, and that led to wildly inaccurate predictions. She went on to say that they didn't expect there to be different types of solar systems simply because they had no point of reference for them. This was interesting to me because it's something I think about quite often; throughout scientific history we have seen time and time again scientists proved wrong because they didn't (and perhaps couldn't) understand the scope of the entire problem, simply because they had never seen anything like it before.
This leads to my question: since we've seen theories corrected over and over again throughout time, how sure are we about our knowledge of the universe currently? How do we search and learn about things we couldn't possibly imagine at this point in time? We have advanced technology to answer these questions, and it seems like the general consensus is that we're sure about the things we know. However, that's also what countless scientists of the past have said.
