A Quote by Nancy Roman
All of the stars rotate, have orbits around the center of the galaxy, and most of them go around the center of the galaxy in nearly circular orbits. They vary a little bit from circular, but they're predominantly circular.

There's a large cluster of stars that are orbiting the center of our galaxy. And by measuring the motion of stars, and in particular, their orbits, we can figure out whether or not there's a central black hole.
I made a circular motion with my finger around my temple to indicate I thought this guy was crazy, forgetting that there was no one in the room to see this circular motion except him. He saw it and frowned.
While most of those who hold that the whole heaven is finite say that the earth lies at the center, the philosophers of Italy, the so-called Pythagoreans, assert the contrary. They say that in the middle there is fire, and that the earth is one of the stars, and by its circular motion round the center produces night and day.
Tis the only discipline we are born for; all studies else are but as circular lines, and death the center where they all must meet.
Every word that judges value is circular. 'Good' is 'right' is 'proper' is 'just' is 'good'. But check the examples, and they're not circular at all: Every one says 'makes me happy'.
The earth is round, all the heavenly bodies are round; they all move on round or elliptical orbits. This same image of circular globe-shaped mini worlds orbiting around each other follows us right down to the microcosmos. We are even aroused by round forms in species propagation related eroticism. Why should I join the straying mass who want to make everything angular? I am going to pursue Galileo Galilei's philosophy: my world is also round.
If you want to see a black hole tonight, tonight just look in the direction of Sagittarius, the constellation. That's the center of the Milky Way Galaxy and there's a raging black hole at the very center of that constellation that holds the galaxy together.
We lived in this area that was basically two circular roads next to each other. There were forests and pastures and stuff. I remember walking around the forest quite a bit.
The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion.
If... the motion of the earth were circular, it would be violent and contrary to nature, and could not be eternal, since ... nothing violent is eternal .... It follows, therefore, that the earth is not moved with a circular motion.
While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.
The key to proving that there's a black hole is showing that there's a tremendous amount of mass in a very small volume. And you can do that with the motions of stars. The way the star moves around the center of the galaxy is very much like the way the planets orbit the sun.
If we're thinking about old civilizations, those that formed a long time ago and there were stars and planets around long before Earth even existed, then these are going to be towards the center of the galaxy. That is the place to look if you think there are ancient civilizations that have made beacons or some other way of attracting our attention.
Men go abroad to wonder at the heights of mountains, at the huge waves of the sea, at the long courses of the rivers, at the vast compass of the ocean, at the circular motions of the stars, and they pass by themselves without wondering.
One day man will connect his
apparatus to the very wheel work of
the universe. The very forces that
motivate the planets in their orbits
and cause them to rotate will rotate
his own machinery.
Science is science. Science is what is. After discovery, tests, trial, if a consensus of scientists today said that the sun orbits around the earth, would we say that they're right simply because there is a consensus? No. Because we know the earth orbits around the sun just as if there were a consensus that the earth is flat would we agree with them? No. So there can't be a consensus on something that hasn't been proven. This is a political movement. This whole global warming thing is a political movement.
