Neil deGrasse Tyson

Ignorance is a virus. And I'm trying to be the vaccine.

I'm often asked what I think about the existence of aliens. My answer is always the same: I hope so.

For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You'd be surprised how far you can get with those two.

My goal is to empower people to think for themselves, to question everything, and to embrace the unknown.

The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.

If you're scientifically literate, the world looks very different to you. And that difference, in my opinion, is for the better.

The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.

I don't have the answers, but I do have the questions. And the questions are far more interesting.

To be an astrophysicist is to be a perpetual student of the universe.

The universe is a grand, cosmic ballet, and we are all dancers in it.

My passion for the stars began as a child, looking up at the night sky from the Bronx.

The greatest discoveries are often made by those who dare to challenge established dogma.

Science is not about belief, it's about evidence.

The beauty of the universe is not just in its vastness, but in its intricate details.

We are living in a golden age of astronomy, with new discoveries being made every day.

My hope is that one day, everyone will feel a connection to the cosmos.

The universe doesn't care about your feelings, but it does care about the laws of physics.

To truly understand the universe, you must be willing to let go of your preconceived notions.

The greatest gift you can give someone is the gift of knowledge.

Every star in the night sky has a story to tell, if only we are willing to listen.
