Adam Riess Quotes

Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.

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

Space is almost infinite. As a matter of fact, we think it is infinite.

Pure science - this vision of the universe as 15 billion light years across - I am bedazzled and awed by it.

The dark energy is not exactly zero, but the first 122 decimal points are zero. That's crazy. That is really one of the craziest things we've ever discovered.

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

Dark energy is perhaps the biggest mystery in physics.

It bears mentioning that the Milky Way is only one of 150 billion galaxies visible to our telescopes - and each of these will have its own complement of planets.

There is nothing bigger or older than the universe.

The universe is a great mystery.

One of the great challenges of modern cosmology is to discover what the geometry of the universe really is.

They've discovered that, where all the other galaxies are moving in one direction, ours is going in another. Now, the Big Bang theory says that we're all moving outward.

They say the universe is expanding. That should help with the traffic.

As a physicist, I've always found cosmology to be a rational elixir; it distances me from ordinary concerns.

I think it's amazing that the entire community of astronomy has done what it's done. We've been able to deduce the nature of time and space and where we all came from. It's the most amazing detective story in history.

We would look up at the night sky together, and although Stephen wasn't actually very good at detecting constellations, he would tell me about the expanding universe and the possibility of it contracting again and describe a star collapsing in on itself to form a black hole in a way that was quite easy to understand.

The Hubble Space Telescope is more than remarkable. It has answered just so many of those fundamental questions that people have been asking about the cosmos since people were able to ask questions.

Astronomers still can't decide what the shape of our universe is. Is it closed and finite, which is to say, is there a countable tally of all the galaxies that exist, even beyond the ones we can see? Or is it infinite? The latter possibility is still on the table.

The universe extends beyond the mind of man, and is more complex than the small sample one can study. God cannot be reduced to a sample for analysis.

And what we know, or think we know, about the universe of space and time is changing very quickly.

We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries - and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?

I always think of space-time as being the real substance of space, and the galaxies and the stars just like the foam on the ocean.

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 wouldn't say that 'The Fabric of the Cosmos' is a book on cosmology. Cosmology certainly plays a big part, but the major theme is our ever-evolving understanding of space and time, and what it all means for our sense of reality.

We know that the expansion of our universe is accelerating, which means a number called the cosmological constant must be positive.
