            The biggest experimental research projects like the Large Hadron Collider are becoming cripplingly expensive. Wouldn't our money be better spent elsewhere?

              Science for the Public 4/30/13. Paul Steinhardt, Ph.D., the Albert Einstein Professor in Science at Princeton University, and Director of the Princeton Center for Theoretical Science. Professor Steinhardt is a faculty member of both the Department of Physics and Department of Astrophysical Sciences at Princeton. Professor Steinhardt has made many important contributions to physics and cosmology. In this program he discusses two of them, providing also numerous examples of how scientists think, how they try to resolve controversies and why they often wait years for confirmation or rejection of their best ideas. Dr. Steiinhardt talks first about the issues of the inflationary model --a period of spectacular expansion of the universe in the Big Bang, and the concept that he and Neil Turok ultimately devised to address the problems of the inflationary model (see their book, Endless Universe). He then discusses the discovery of a quasi-crystal -an object that was thought to be impossible, and his great adventure of actually tracking down examples of the crystal (an adventure that deserves a movie).

                The idea of a "purpose" or "reason why" has a strong hold on the human imagination, and has a special resonance when we think about the universe itself. However, modern science has gradually eroded the role of purpose in our best understanding of nature. This represents an important step forward in human understanding, as we can see how apparently purposeful features of reality arise through undirected laws of nature. But it represents a challenge for questions of morality and meaning. I will argue that purposes can be created or emergent even when they are not fundamental, and that this perspective has important consequences for how we live our lives. Biography: Dr. Carroll is a theoretical physicist at Caltech in Pasadena, CA doing research on theoretical aspects of cosmology, field theory, and gravitation. He is especially interested in inflation, the arrow of time, and what happened at or before the Big Bang. He's done work on dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. His latest book is The Particle at the End of the Universe: How the Higgs Boson Leads us to the Edge of a New World. It's about the Large Hadron Collider, the search for the Higgs Boson, and the people who made it happen. As an author, he has also written From Eternity to Here: The Quest for the Ultimate Theory of Time and a graduate textbook, Spacetime and Geometry: An Introduction to General Relativity. He has recorded lectures for the Teaching Company on Dark Matter and Dark Energy and the Mysteries of Time. He has maintained a popular blog since 2004.

                  Question on Yahoo Answers from 2009 Where does life come from? I know the theory of evolution explains how life as we know it has developed. But how did life itself get started on the planet?? Again I understand that there is no hard and fast answer to this but does anyone have any theories?? I wass thinking, could it be from an extra terrestrial source? for example, what if an asteroid crashed into earth millions of years ago that had a single cell alien ameoba on it, or something similar? Could it then be possible to assume that that asteroid didnt hit our planet by chance but was directed here? Could it then be done again? if the human race continues to ruin our planet could we put some human dna onto a load of asteroids and fire them out in all directions with the hope that one of them will find a planet that can bear life? therefore saving the human race from extinction Best Answer - Chosen by Asker First of all, whatever your received answer, it's going to be a hypothesis before an evidence comes out to support it. we need to first define life, what is life ? the common thing between life and non-life is that both share the same essence (Matter) the difference is that the life is animated and the other is not.therefor life is animated and the other is not. in Natural Science , Abiogenesis is the study that Amino acids, often called "the building blocks of life", can form via natural chemical reactions unrelated to life, as demonstrated in the experiments, which involved simulating the conditions of the early Earth. An alternative to Earthly abiogenesis is the hypothesis that primitive life may have originally formed extraterrestrially, either in space or on a nearby planet Organic compounds are relatively common in space, especially in the outer solar system where volatiles are not evaporated by solar heating. Comets are encrusted by outer layers of dark material, thought to be a tar-like substance composed of complex organic material formed from simple carbon compounds after reactions initiated mostly by irradiation by ultraviolet light. It is supposed that a rain of material from comets could have brought significant quantities of such complex organic molecules to Earth. Just my 2 cents
