Will modern science be proved wrong?
Me and my sister were discussing this earlier. Will currently respected knowledge be disproven in the way science always has been in the past?
It depends what you call respected knowledge. Most top scientists don't view the world with the same certainy that more ignorant people do.
Some things that the media calls science are not science at all, but just wild speculation.
The media is obsessed with the work of a few scientist such as Einstein. Einstein was known to be wrong about much of his work at the time he published it, yet the media has always portrayed him as an infallible genius.
Stephen Hawking's work on Black Holes is also highly speculative and not supported by any hard evidence.
The Big Bang theory is taught in schools as fact, even though there is no evidence to support it other than the direction of travel of observable matter. There are tremendous holes in the theory.
Chemisty as taught in schools has always been bogus. The image given of electrons flying around atoms is pure nonsense. It works as a way of understaning chemical reactions, but it is not reality.
Modern medicine is very young and is often based on bigotry and vested interests, so much of it is wrong. Big money will sadly always pervert medical research efforts.
Modern Geology is an even younger science. We are only just learning how to measure and understandand the behaviour of the earth beneath our feet.
Evolutionary biology is still short of sufficient data, to have a complete picture of the evolution of the species. Some evolutionary events such as animals becoming warm blooded cannot be determined from fossils and skeletons, so we are guessing for now. In the future we will know better, if intact DNA is ever found in prehistoric bones. The more DNA we find and decode of more recent species, the more we understand of the evolutionary process.
Most physicists agree that there is great uncertainty about science's understanding of the universe. Most theories have serious question marks over them, and there are theories, such as the existence of parallel universes, which we do not have any way of testing at this time.
At the begining of the 20th century Heissenberg proved beyond doubt, that no physics experiment could ever be 100% reliable. Other's showed the physical world to be random and chaotic, rather than ordered according to Einstein. Einstein went to his grave still trying to refute what no-one else continued to believe.
All science is by definition experimental. It should never be regard as certain. That is not to say some science is beyond reasonable doubt. For example no-one is yet to challenge Newton's laws of motion (taking into account relativity).
You should always remember that most scientists need to earn a living so you need to look at their motives before you blindly accept their claims. That is why unviersity scientists sponsored by Nestle's will claim powdered milk is best for babies in the third world, whilst government scientist all agree that breast is best.
