A Quote by Priyamvada Natarajan
As an astrophysicist, my research work involves mapping dark matter, the elusive substance that accounts for about a quarter of our universe.

From a scientific point of view, our mission is to seek answers to the fundamental questions about the universe. Many are open - we don't know about dark matter, which accounts for a quarter of the universe's matter, nor do we know why there's antimatter.
I'm an astrophysicist and a professor, so my day job involves manipulating intractable numbers that characterize our universe.
I believe in research. Each movie at Pixar involves research with college professors or taking trips to learn as much as we can about a particular subject matter.
When we look at the universe, what we see by eye or with our telescopes is only five percent of the universe. The rest, 95 percent is dark. Dark meaning, first of all, not visible to our instrument. Second, dark also indicates our ignorance. We don't know what's the composition of this part of the universe.
I got fascinated by the idea that our universe itself is comprised mostly of dark matter and dark energy. Things that we can't perceive at all, and we've only discovered that relatively recently. So it's almost as if our universe is the foam on the ocean of things that we can't see, or know, or perceive, and yet we feel the affects of those things right and left.
In terms of the most astonishing fact about which we know nothing, there is dark matter and dark energy. We don't know what either of them is. Everything we know and love about the universe and all the laws of physics as they apply, apply to four percent of the universe. That's stunning.
We still don't know what about 96 per cent of the universe is made of. It is dark matter and dark energy, but we have no idea what it is.
According to quantum field theory, fields alone are real. They are the substance of the universe and not 'matter'. Matter is simply the momentary manifestation of interacting fields which, intangible and insubstantial as they are, are the only real things in the universe.
However, one new theory says that dark matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain dark matter.
When I grew up I assembled my role models à la cart. I wanted to be an astrophysicist. If I tried to find a role model who grew up in the Bronx with my skin color who was an astrophysicist, I would never have become an astrophysicist.
I as an astrophysicist, see the universe, feel the universe, smell the universe every day. Every day. And for people to say, I'm cool, I'm right here, it's all I need.
Dark matter is one of the dominant constituents of the universe, which piled up in certain parts of the universe due to gravity, and in those regions, galaxies were formed. It is the unseen thing that holds the universe together.
There is neither spirit nor matter in the world. The stuff of the universe is spirit-matter. No other substance but this could have produced the human molecule.
We account for all the matter and energy that we're familiar with, measure up how much gravity it should have, it's one-sixth of the gravity that's actually operating on the universe. We call that dark matter. It really should be called dark gravity. We don't know what that is.
Man is a machine and in the whole universe there is but a single substance, matter, variously modified.
I'd love to do something funny. Our work often deals with tough subjects. You do your research and it can be quite dark. So after all these years of drama, I'd like to go to work someday with the sole intention of making people laugh.
