Priyamvada Natarajan Quotes

According to the standard model billions of years ago some little quantum fluctuation, perhaps a slightly lower density of matter, maybe right where we're sitting right now, caused our galaxy to start collapsing around here.

I'm baffled all the time. We don't know what's driving 96% of the universe. Everybody you know and love and heard of and think about and see in the night sky through a telescope: four percent of the universe.

Among the questions we have in mind: dark matter, antimatter, and matter symmetry.

We know there must be new physics. For example, we cannot explain what dark matter is.

If dark matter and dark energy are 95 percent of everything, shouldn't we all be asking questions about that? What does that look like?

In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

My main interest is the problem of the singularity. If we can't understand what happened at the singularity we came out of, then we don't seem to have any understanding of the laws of particle physics. I'd be very happy just to understand the last singularity and leave the other ones to future generations.

It now appears that the way the universe began can indeed be determined, using imaginary time.

Cosmology is a rapidly advancing field.

We have a remarkably complete picture in many ways - and it could be that we're not accounting for something that's almost three-quarters of the entire universe.

A full understanding of what happens in our everyday lives needs to take into account what happened at the Big Bang. And not only is that intrinsically interesting and just kind of cool to think about, but it's also a mystery that is not given much attention by working scientists; it's a little bit underappreciated.

The missing link in cosmology is the nature of dark matter and dark energy.

My present work concerns the problems connected with the theory of elementary particles, the theory of gravitation and cosmology and I shall be glad if I can manage to make some contribution to these important branches of science.

General relativity is the cornerstone of cosmology and astrophysics. It has also provided the conceptual basis for string theory and other attempts to unify all the forces of nature in terms of geometrical structures.

I spent most of my career doing high-energy physics, quarks, dark matter, string theory and so on.

We'll have four different gravitational wave windows open within the next 20 years, and each of them will see something different. We'll be probing the birth of the universe with this. The so-called 'inflationary era' of the universe. We'll be probing the birth of the fundamental forces and how they came into being.

I am deeply impressed with the way dark matter has explained cosmological observations.

Dark matter is particularly intriguing because it's some kind of particle - that's for sure.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

I want to know what dark matter and dark energy are comprised of. They remain a mystery, a complete mystery. No one is any closer to solving the problem than when these two things were discovered.

I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

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.

Observations indicate that the universe is expanding at an ever increasing rate. It will expand forever, getting emptier and darker.

Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.
