Can we trust what we know?

I was reading the Van Lagemaat book earlier where i came across a problem. In one of the paragraphs where he talks about wheter or not belief is a part of knowledge he gives an example of something we 'know for sure'. He says that, "many years ago people thought the Earth revolved around 7 planets and the sun, but no we know that in fact the Earth and eight other planets revolve around the Sun'. However know we know that infact this is not true due to the fact that Pluto is no longer a planet. Unknowingly Van Lagemaat has either completely proved his point or miserably disproved his theory, depending on the way you look at it. Being the cynic I am I chose the latter.
Either way the point is that we really don't know; anything. A group of qualified scientists who are the best in their field can tell us something that we take for truth. But years later people may be looking back on us wondering how we got it so wrong.
It really got me thinking about everything I 'know' and it's a scary thought that one could dedicate their life to doing something based on what they 'know' only for it to all be proved pointless by people in the future doing what they 'know' which could then in turn be disproved again and again infinitely.
