I build a “case for noteverything", with 3 levels of analysis.I first contemplate the complementary realms of “faith" and “science" and place the concept of “theory of everything" firmly in the faith category.We investigate the technical problems of using them to make power plants and starships. Next, we consider what challenges the ABH proposal would pose for a future quantum theory of gravity.
Louis Crane completed a Ph D in Mathematics at the University of Chicago, did a postdoc at the Institute for Advanced Study in Princeton, and was an Assistant Professor at Yale University.
He then joined the Mathematics department at Kansas State University, where he has remained to this day, except for visits to Nottingham University, Universite de Paris VII (Diderot), The University of Western Ontario and Instituto Superior Tecnico in Lisboa, Portugal. The question of whether it is possible or not to surpass the speed of light is already centennial.
In seeking ever-broader theoretical ‘umbrellas' for physical phenomena, we are seeking unifying principles.
Emergent phenomena have turned out to be some of the most difficult to explain, causing ‘clash of umbrellas,' so-to-speak.
The special theory of relativity took the existence of a speed limit as a principle, the light postulate, which has proven to be enormously predictive.
Here we discuss some of its twists and turns when general relativity and quantum mechanics come into play.Jump to: Louis Crane • Carlos Barcelò, Stefano Finazzi, & Stefano Liberati • Sabine Hossenfelder • Giovanni Amelino-Camelia • Amedeo Balbi • Ian Durham • Ted Jacobson & Thomas P.Sotiriou • Gheorghe Sorin Paraoanu • Dean Rickles • Norman D.Cook • Richard Easther • Hans-Thomas Elze • Marcelo Gleiser • Lev Goldfarb • Florin Moldoveanu • Maulik Parikh • Vesselin Petkov • Tejinder Singh • Navin Sivanandam We discuss a proposal to make small artificial black holes (ABH's) using a huge laser.Because of Hawking radiation, they would be extremely powerful energy sources.For this, I will first distinguish three different reasons why the possibility of progress is doubted and offer examples for these cases.Based on this, one can then identify three reasons for why progress might indeed be impossible, and finally conclude that it is impossible to decide which case we are facing.Here, we show that the quantum back-reaction to warp-drive geometries, created out of an initially flat spacetime, inevitably lead to their destabilization whenever superluminal speeds are attained. He is currently a Ph D student in SISSA (Italy) working on gravitation theory under the supervision of S. He is currently a research professor at SISSA working on gravitation theory.We close this investigation speculating the possible significance of this further success of the speed of light postulate. Barcelo did his Ph D in IAA (Spain) and postdocs at Washington University in St. He is currently deputy director of the IAA and works on gravitation theory. At any time, there are areas of science where we are standing at the frontier of knowledge, and can wonder whether we have reached a fundamental limit to human understanding. I will argue here that it is ultimately impossible to answer this question.Contest Partner: The Peter and Patricia Gruber Fund.read/discuss • winners Trick or Truth: The Mysterious Connection Between Physics and Mathematics Contest Partners: Nanotronics Imaging, The Peter and Patricia Gruber Foundation, and The John Templeton Foundation Media Partner: Scientific American read/discuss • winners How Should Humanity Steer the Future?
