When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'
We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct. My own feeling is that it is not crazy enough.
Interpretation
What this quote means
This quote reflects the idea that sometimes, unconventional theories can lead to groundbreaking discoveries, though they need to be sufficiently bold to be credible.
Niels Bohr’s quote suggests that the nature of scientific theories often requires a degree of boldness or unconventional thinking to be considered valid. While it is common for groundbreaking ideas to be initially dismissed as crazy, there is a nuanced difference in the level of 'craziness' that may actually lead to correct theories. Bohr implies that some theories may not push boundaries enough to be impactful, indicating that real progress in science often comes from thinking outside the box.
