In a spiral galaxy, the ratio of dark-to-light matter is about a factor of ten. That's probably a good number for the ratio of our ignorance-to-knowledge. We're out of kindergarten, but only in about third grade.

We know very little about the universe. I personally don't believe it's uniform and the same everywhere. That's like saying the earth is flat.
Interpretation
The universe is complex and diverse, not uniform like a flat Earth.
Vera Rubin emphasizes the vast unknowns of the universe and challenges the notion of uniformity across its expanse. By comparing the idea of a uniform universe to the outdated belief of a flat Earth, she highlights the necessity of questioning assumptions and recognizing the intricate, diverse nature of the cosmos.

In a spiral galaxy, the ratio of dark-to-light matter is about a factor of ten. That's probably a good number for the ratio of our ignorance-to-knowledge. We're out of kindergarten, but only in about third grade.
We need senators who have studied physics and representatives who understand ecology.
Nobody ever told us all matter radiated. We just assumed it did.
There was just nothing as interesting in my life as watching the stars every night.
I try to do my science in a moral way, and, I believe that, ideally, science should be looked upon as something that helps us understand our role in the universe.
I had the usual friends who pointed out constellations of stars. But it really was watching the stars. It was getting some sense of the motion of the earth. I found it a remarkable thing.
The universe is almost like a huge magic trick and scientists are trying to figure out how it does what it does.
Based on the science, you can make somewhat clear statements: The number of people who can survive on six hours of sleep without impairment is zero.
I don't expect that the million will ever be won, simply because there is no confirming evidence for any paranormal claims to date.
The ride to orbit was impressive, as it always is. But once I got on board the space station, it really felt like I was visiting an old home; it felt very comfortable.
What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences. The secret of antibody diversity would emerge from that. Fortunately at the time I was sufficiently ignorant of the subject not to realise how naive I was being.
[About the great synthesis of atomic physics in the 1920s:] It was a heroic time. It was not the doing of any one man; it involved the collaboration of scores of scientists from many different lands. But from the first to last the deeply creative, subtle and critical spirit of Niels Bohr guided, restrained, deepened and finally transmuted the enterprise.
