I have lived my life with science and I would say that many scientists are very ignorant. They should know that they only know what has already been proven but not that which has not yet been discovered. We constantly grow in our knowledge. I can remember always hearing at different times that scientists had discovered the smallest particle of an atom. The next year I would hear the same, then the next year and so on. To say that something is impossible, is to say that they have a complete knowledge of everything. This is never possible. In the past, hundreds of years ago, scientists would say most of the things we have accomplished today were impossible. Yet, they are here. They are no longer considered magic but scientific fact. Even with quantum physics making the discoveries they have made, many scientists do not seem aware that there are other realities and that ours is just one.
