Professor Lawrence M. Krauss, thank you very much for providing your precious time for our magazine. Personally I am very happy and much eager to talk to the best-selling author of several books and more than 300 research publications & Director, The Origins Project at ASU and Foundation Professor, School of Earth & Space Exploration and Physics Department Arizona State University. I would like to welcome you to this session On New Dimension Magazine.
I try and agree to do many different things, and then juggle them one at a time. I find that if I don’t have a lot to do, I sometimes do very little. I tend to focus intensively on one thing at a time, and work through the list. Sometimes I have to focus on 3 or 4 very different things in a single day, but I actually like the variety as well.
“It is the story of the remarkable effort humans have made to understand the fundamental forces that govern nature, and to strip back the illusion of reality that we experience on human scales to understand the underlying structure beneath it.”
“The Universe isn’t fine tuned for life. Life is fine-tuned for the universe. If the parameters of the universe were different perhaps different life forms might be possible. Moreover, even quantities like the energy of empty space, which seems to be so small compared to the value it might have, and which, if it were any larger, would not allow galaxies to have formed, could nevertheless have been much smaller and the universe would be more conducive to life. And a value of zero for this quantity would seem very natural indeed.”
“Well, quantum mechanics allows for the spontaneous emission of particles like photons, the particles that make up light, whenever an electron changes its state in an atom. The photon appears from nothing. It was not in the atom before it was emitted. It simply appeared. Similarly, it turns out that elementary particles can spontaneously appear in empty space, once again due to the properties of quantum mechanics, this time in combination with relativity. If gravity is a quantum theory, then the variables that gravity describes, space and time, become quantum mechanical in nature, and whole space-times can appear spontaneously. This means that whole universes can appear that did not exist before. And it turns out our universe has the properties that one would expect from a universe that spontaneously appeared from nothing in this way.”
“Natural-Philosophy, what we now call Science is the best, and I believe, the only reliable way to understand how the physical universe operates.”
“Our universe had, as far as we can tell, a beginning, about 13.8 billion years ago. As far as we can tell, both space and time may have begun then. Now, as far as we can tell, our universe may expand forever. So in that sense time could be infinite..(or as we say in physics or mathematics, semi-infinite). And it is true that if our universe exists into the indefinite future then many strange aspects of infinity, including the possible repetition of everything we experience, an infinite number of times, for separate versions of us, might be possible. But we certainly don’t know if this is the case, and the conditions of the future universe could change so that life forms like us could not exist in the far future in any case.”
“There has been a lot of mathematical development, and interest techniques have been developed that have been useful in other areas of physics. But fundamentally my earlier statement remains the same.”
“An atheist is simply someone who finds the argument for God unconvincing. Everything I have learned as a scientist over the past 35 years makes God not only seems highly unlikely, but largely redundant even if such an entity did exist. There is no evidence for miracles, and the laws of physics describe the history of the universe back to the earliest moments of the big bang without supernatural shenanigans.”
“No, I don’t think so. A vague ‘deist’ notion.. Assuming some purpose or order in the universe determined by some unknown intelligence, cannot be refuted by science. It is just unnecessary. But the Gods of the world’s major religions are all not in accord with our scientific understanding of nature. I wouldn’t call it dishonesty. Religion is foisted on young people, and it is hard to overcome.. We all tend to believe in mutually contradictory things at one time or another.”
“Who knows? The world is a dangerous place, and we have to wake up to those dangers and begin to think globally. As Einstein said many years ago after the first nuclear explosion, “Everything has changed, save the way we think”. Unfortunately our thinking remains the same.”
“Keep doing what you love. Don’t get discouraged by others. Work hard, and enjoy discussing your work with others. .”
