Barbara Bradley Haggerty Quotes

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

We can trace things back to the earlier stages of the Big Bang, but we still don't know what banged and why it banged. That's a challenge for 21st-century science.

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.

A universe that came from nothing in the big bang will disappear into nothing at the big crunch. Its glorious few zillion years of existence not even a memory.

The cyclic universe theory predicts no gravitational waves from the early universe.

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.

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.

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.

People have contemplated the origin and evolution of the universe since before the time of Aristotle. Very recently, the era of speculation has given way to a time of science.

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.

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.

There was no 'before' the beginning of our universe, because once upon a time there was no time.

Science sent the Hubble telescope out into space, so it could capture light and the absence thereof, from the very beginning of time. And the telescope really did that. So now we know that there was once absolutely nothing, such a perfect nothing that there wasn't even nothing or once.

Something pretty mysterious had to give rise to the origin of the universe.

Physicists are working on the Big Bang, and one day they may or may not solve it.

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.

Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe.

If the Big Bang is true, that means everything that came out of it, all of the particles, all of us, there is a scientific force that connects it all that we don't really know about.

The Big Bang, which today we hold to be the origin of the world, does not contradict the intervention of the divine creator but, rather, requires it.

Physicists explain creation by telling us that the universe began with the Big Bang, an intense energy singularity that continued expanding. But who created the singularity?

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

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.

I believe in a kind of God. I think all scientists, in a way, believe in a certain God, in a certain order of nature.

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

Cosmology is a rapidly advancing field.
