In order to displace a prevailing theory or paradigm in science, it is not enough to merely point out what it cannot explain; you have to offer a new theory that explains more data, and do so in a testable way.
Sentiment: NEGATIVE
Never abandon a theory that explains something until you have a theory that explains more.
Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
The system becomes more coherent as it is further extended. The elements which we require for explaining a new class of facts are already contained in our system. In false theories, the contrary is the case.
Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.
It is impossible to advance new theories... when you are under the influence of a particular view, or under the pressure of a particular dogma.
It is that of increasing knowledge of empirical fact, intimately combined with changing interpretations of this body of fact - hence changing general statements about it - and, not least, a changing a structure of the theoretical system.
We know there must be new physics. For example, we cannot explain what dark matter is.
I'm not sure what theory is, unless it's the pursuit of fundamental questions.
The incorrectness and weaknesses of a theory cause other minds to formulate the problems more exactly and in this way scientific progress is made.
I believe all complicated phenomena can be explained by simpler scientific principles.
