The Wonder of the Cosmos (through an Upgraded Lens)
by Colleen Scheck, producer
Last week NASA published pictures from the newly-refurbished Hubble telescope. Beautiful. Mysterious. Divine. And, simply, Wow. These were the words that ran through my head when I saw them. It’s worth reading the descriptions of the photos on NASA’s site for more detail on these galactic happenings. I also liked this online comment:
"These photos, and the multi-billion year life behind them make me think I’ve wasted the better part of my life looking down at my feet, instead of looking up into the sky."
I don’t have profound thoughts to add, but comments from two cosmologists who have been on SOF seem to apply. From our show "Science and Hope," George Ellis, a practicing Quaker from South Africa:
Ms. Tippett: How do you — because you’re telling me that you also, I believe, you’re telling me you have concluded that there is a God and there can be a God in your cosmology. But how do you think your way around into that question?
Dr. Ellis: It’s a very valid question, and it’s one for which we haven’t got any clue to the answer. But that is the same for every attempt to understand the foundations of the universe. Science runs into that and religions run into that. My colleagues are producing theories of what they call creation of the universe out of nothing. But when you probe them, you find they’re not producing theories of creation of the universe out of nothing. They are assuming a huge machinery of quantum field theory and fields and particles and interactions, which generates universe, not creation of the universe out of nothing.
Ms. Tippett: Which had to come from somewhere.
Dr. Ellis: Yeah, it had to come from somewhere else….And in the end, we run into a metaphysical blank, whether you pursue it scientifically or religiously, and you simply have to give up in wonder and awe and say, ‘I don’t know the answer, and it’s just marvelous the way things are.’
And, Janna Levin, a novelist and professor of Physics and Astronomy at Barnard College, spoke with Krista for our program "Mathematics, Purpose, and Truth":
Ms. Tippett: ….What are you working on that also, you know, starts to reshape the way you see the world around you and the way you move through it?
Ms. Levin: Well, it’s funny, people have often asked, when I’ve been describing the work that I’m doing, they’ll say, ‘Well, who — why should I care about that?’ I’m telling something about extra dimensions and maybe the universe isn’t three-dimensional, but maybe there are extra spatial dimensions. It is very abstract. We could do a whole show hammering that out.
Ms. Tippett: Yeah, yeah.
Ms. Levin: But supposing we grasp the notion of multidimensional space and spaces and finite, people say, ‘Why should I care about that? You know, my taxes are high. We’re on a war in Iraq.’ And these are fair questions, but my feeling is that it changes the world in such a fundamental way. We cannot begin to comprehend the consequences of living in a world after we know certain things about it. I think we cannot imagine the mindset of somebody pre-Copernicus, when we thought that the Earth was the center of the universe, and that the Sun and all the celestial bodies orbited us.
It’s really not that huge a discovery in retrospect. In retrospect, so we orbit around the Sun, and we take this to be commonplace, and there’s lots of planets in our solar system, and the Sun is just one star out of billions or hundreds of billions in our galaxy, and there are hundreds of billions of galaxies. And we become, you know, little dust mites in the scheme of things. That shift is so colossal in terms of what it did, I think, to our world, our global culture, our worldview, that I can’t begin to draw simple lines to say, ‘This is what happened because of it’ or ‘That’s what happened because of it.’
Ms. Tippett: Right, right.
Ms. Levin: We see ourselves differently, and then we see the whole world differently. And we begin to think about meaning — and all of these questions that you’ve brought up — completely differently than we did before. And I’d feel the same way if we discovered that the universe is finite or if we discovered that there are additional spatial dimensions, if these things will impact us, I think, in ways that we can’t just draw simple cause-and-effect arrows.
