Duane G. Carey Quotes

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

For almost a century, the Universe has been known to be expanding as a consequence of the Big Bang about 14 billion years ago. However, the discovery that this expansion is accelerating is astounding. If the expansion will continue to speed up, the Universe will end in ice.

It was only about sixty years ago that the expansion of the universe was first observed.

Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the universe from collapsing. And so he discovered, in his theory of gravity, something like this dark energy - he called it a cosmological constant - could play this role, pushing things away.

We've known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make up about 70 percent of the universe.

The original project began because we know the universe is expanding. Everybody had assumed that gravity would slow down the expansion of the universe and everything would come to a halt and collapse. The big surprise was it was actually speeding up.

Eventually, when the universe expands enough, all that will be left is the dark energy.

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

We already have a pretty good knowledge of the universe's mass-energy content, so if we can get a handle on its geometry, then we will be able to work out exactly what the fate of the universe will be.

We account for one-sixth of the forces of gravity we see in the universe. There is no known objects accounting for most of the effective gravity in the universe. Something is making stuff move that is not anything we have ever touched.

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

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

You might expect gravity would slow it down, but it's just expanding faster and faster.

'First Light' is nonfiction, a true story about astronomers who are looking for light coming from the edge of the universe. It tells how science is really done - and science is a lot weirder and more human than most people realize.

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.

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

The universe is expanding, and every second that you're alive, the universe is bigger than it was a second before. There's nothing in front of us, exactly, other than the future, and there's no space for the size, the density of the universe to go. Because it's expanding at every point simultaneously.

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

It seemed like my favourite kind of job - a wonderful chance to ask something absolutely fundamental: the fate of the Universe and whether the Universe was infinite or not.

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.

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

The universe starts off with the Big Bang theory, and the first thing that emerged from the Big Bang is essentially hydrogen and then helium. And that's what combusts in stars. Finally, stars implode, and they build heavier elements out of that. And those heavier elements are reconstituted in the heart of other stars, eventually.

The Big Bang theory is the idea that if we go back early enough in the history of the universe - and we can do this, of course, by looking at starlight coming to us from billions of years ago - we will see a very hot and dense period where the universe was much smaller, denser, and hotter.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.
