One has to balance accuracy versus complexity. We can make predictions for simple systems more easily than for complex systems. It is very difficult to predict the evolution of a complex system far into the future. An example of this is the accurate prediction of weather. In order to update their models, meteorologists must constantly monitor and update parameters such as temperature, pressure, humidity, wind, solar radiation, etc.
Science is objective and well-scrutinized.
Some scientists are forming cliques and lobbies which do not allow certain views and theories to see the daylight. Even if the theories are correct, these scientists discredit them and their originators and prevent them from being published in scientific journals. One does not have to burn a person in order to kill his or her spirit. Scientific discoveries, when not properly used can lead to destruction of the Planet and Life. Unfortunately in many cases this is done.
