Lawrence M. Krauss Quotes

That's what Hubble can do for us. It can tell us whether the universe is expanding forever or if one day it's going to come back together.

There are lots of ideas which extend the Copernican principle one step further. We went from the solar system to the galaxy to zillions of galaxies and now to realising even that isn't all there is.

Scientists - who prefer explanations subject to laboratory tests - figure that everything we see today was as inevitable as wrinkles, once the Big Bang established physics. Stars and planets were cooked up as huge clouds of matter collapsed and coalesced.

With COBE, we can see things before the lights came on. While we probably will not rewrite the book of cosmology with this mission, we will write another chapter.

This is the result of six billion years of evolution. Tonight, we have given the lie to gravity.We have reached for the stars.

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.

Seeing outward is equivalent to looking backward in time because the telescope's mirror is capturing primeval light... galaxies that existed before our time.

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.

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

I am sorry to say that there is too much point to the wisecrack that life is extinct on other planets because their scientists were more advanced than ours.

The development of the telescope, together with increased knowledge of things, brought men to see that the earth is not what man had once thought it to be.

Throughout history, when societies have been faced with big challenges, they've put their best people on them. During the Space Race, American and Russian scientists, engineers, astronauts and cosmonauts pushed the bounds of what was possible and landed men on the moon.

It's everywhere, really. It's between the galaxies. It is in this room. We believe that everywhere that you have space, empty space, that you cannot avoid having some of this dark energy.

It's not going to do any good to land on Mars if we're stupid.

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

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.

The world has become a larger place. The universe has been expanding, and Perl's been expanding along with the universe.

The universe at large is full of questions that we still don't know anything about, and there will be always young people, brilliant, who are going to make new discoveries.

I dreamt of being an astronomer; I had a series of 'How and Why' books on the planets and the stars. At that stage, there were only 14 galaxies; now there are multiverses, dark matter, the nano-microscopic world of the interior of atomic structure.

You see billions and billions of stars and recognize that you know some of those have planets, too, and maybe there's life out there, and this is just one of billions of galaxies... and so it gives you this huge perspective of how far we potentially have to go for real exploration.

The Kecks will allow us, like no other telescope in history, to view the evolving universe that gave us birth.

The universe is very big - there's about 100,000 million galaxies in the universe, so that means an awful lot of stars. And some of them, I'm pretty certain, will have planets where there was life, is life, or maybe will be life. I don't believe we're alone.

Hubble has established for the first time that the distant universe looks different from the nearby universe.

The James Webb Space Telescope was specifically designed to see the first stars and galaxies that were formed in the universe. So we're gonna see the snapshot of when stars started. When galaxies started. The very first moments of the universe. And my bet? There's gonna be some big surprises.

Why do more than 40 percent of Americans think that the Universe began after the domestication of the dog?
