Nuclear physicist and alien contactee Charles Hall maintains there exists in nature force fields which western science can easily duplicate, that could allow us to travel in space, even faster than light.
However, according to Hall we are living in a time that is exactly the opposite to how it was during the life of Galileo. At that time, science was transcending the archaic and boxed-in views of Religious Thinkers and Philosophers. That is, Galileo was thinking “outside the box”. Today, Hall maintains, scientists are the ones who are boxed in, hanging on to the notion that travel faster than light is impossible, since Einstein said it was so. If modern western scientists were to take Charles’ advice and experiment with certain force fields, we might come to a completely different view of what is possible. It would then be practical to travel to- and from planets & galaxies many light years away. Perhaps we are not nearly as isolated a planet as we believe we are!
