Don't confuse hypothesis and theory. The former is a possible explanation; the latter, the correct one. The establishment of theory is the very purpose of science.
Sentiment: POSITIVE
There can be theory but, you know, the problem is you've got to be able to test it. So theories are one thing, testing is another.
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.
A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.
Theory not only formulates what we know but also tells us what we want to know, that is, the questions to which an answer is needed.
Theories, for me, are just about freeing your mind. It doesn't mean the theory is going to work like a scientific theory works. It's about freeing your mind and making you think a different way.
The end of science is not to prove a theory, but to improve mankind.
I'm not sure what theory is, unless it's the pursuit of fundamental questions.
Theory helps us to bear our ignorance of facts.
Is evolution a theory, a system, or an hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true.
To understand the theory which underlies all things is not sufficient. Theory is but the preparation for practice.
