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 By comparing the idea of a uniform universe to the outdated belief of a flat Earth, she highlights the necessity of questioning assumptions and recognizing the intricate, diverse nature of the cosmos.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 practice
In a science class discussing the nature of the universe.
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.
I have experimental evidence that time travel is not possible.
There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.
The most complex object in the known universe: brain, only uses 20 watts of power. It would require a nuclear power plant to energize a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that's a compliment.
A study of Disease-of Pestilences methodically prepared and deliberately launched upon man and beast-is certainly being pursue in the laboratories of more than one great country. Blight to destroy crops, Anthrax to slay horses and cattle, Plague to poison not armies but whole districts - such are the lines along which military science is remorselessly advancing.
There are two major challenges before Indian agriculture today: ecological and economical. The conservation of our basic agricultural assets such as land, water, and biodiversity is a major challenge. How to make agriculture sustainable is the challenge.
A man has no reason to be ashamed of having an ape for his grandfather. If there were an ancestor whom I should feel shame in recalling it would rather be a man who plunges into scientific questions with which he has no real acquaintance, only to obscure them by an aimless rhetoric.
