Neil Turok Quotes

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

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.

It may be that we live in an endless universe, both in space and in time. And there've been Bangs in the past, and there will be Bangs in the future.

The main efforts of investigators have been in papering over contradictions in the big bang theory, to build up an idea which has become ever more complex and cumbersome.

Sure, nobody will make a fortune if we figure out why the Big Bang happened. But just about everyone would like to know.

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.

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

First of all, the Big Bang wasn't very big. Second of all, there was no bang. Third, Big Bang Theory doesn't tell you what banged, when it banged, how it banged. It just said it did bang. So the Big Bang theory in some sense is a total misnomer.

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

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.

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.

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

We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.

In the beginning there was nothing, which exploded.

There may be many Big Bangs that happened at various and far-flung locations, each creating its own swelling, spatial expanse, each creating a universe - our universe being the result of only one of those Big Bangs.

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

We people of the Earth exist because our potential was there in the Big Bang, 13.7 billion years ago, as the universe exploded into being.

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

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

Asking what was before the Big Bang is like asking what is North of the North Pole. It is not a defined question and has no meaning.

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.

The predominant theory of the origin of the universe is the Big Bang.

I don't know why anyone would want to study the expansion of the universe.

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.
