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.
Sentiment: NEGATIVE
I'm not sure what theory is, unless it's the pursuit of fundamental questions.
It is a test of true theories not only to account for but to predict phenomena.
You have to test your hypothesis against other theories. Certainty in the face of complex situations is very dangerous.
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.
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.
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.
A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.
A theory must be tempered with reality.
One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.
Good tests kill flawed theories; we remain alive to guess again.
