In a spiral galaxy, the rotational velocity of the stars is nearly constant with distance from the center, implying that there is a great deal of unseen matter beyond the optical disk.

We are like children who have found a puzzle, and we are trying to put it together, but we don't know what the picture is supposed to be.

The universe is a much stranger place than we could have imagined.

Science progresses best when observations force us to alter our preconceptions.

I like to think that the universe is not only stranger than we imagine, but stranger than we *can* imagine.

The dark matter problem is one of the most exciting and challenging problems in modern astronomy.

We have to be open to the possibility that our current understanding of physics is incomplete.

The biggest discovery will be when we understand what dark matter is.

I have spent my life trying to understand the universe, and I am still amazed by its mysteries.

The universe is full of surprises, and that's what makes it so fascinating.

My early interest in astronomy was fueled by a desire to understand the big questions.

It's important to encourage young women to pursue careers in science.

The data speaks for itself, if you listen carefully enough.

Don't be afraid to challenge established ideas.

The beauty of science lies in its ability to reveal the hidden workings of the cosmos.

Every new observation opens up new questions.

The universe is not static; it is constantly evolving.

I never set out to prove dark matter; I just followed the data.

The most exciting moments in science are when you discover something completely unexpected.

We are all part of this grand cosmic dance.
