BEYOND SPACE and TIME the Secret Network of the Universe: How Quantum Geometry Might Complete Einstein’S Dream
BEYOND SPACE AND TIME The secret network of the universe: How quantum geometry might complete Einstein’s dream By Rüdiger Vaas With the help of a few innocuous - albeit subtle and potent - equations, Abhay Ashtekar can escape the realm of ordinary space and time. The mathematics developed specifically for this purpose makes it possible to look behind the scenes of the apparent stage of all events - or better yet: to shed light on the very foundation of reality. What sounds like black magic, is actually incredibly hard physics. Were Albert Einstein alive today, it would have given him great pleasure. For the goal is to fulfil the big dream of a unified theory of gravity and the quantum world. With the new branch of science of quantum geometry, also called loop quantum gravity, Ashtekar has come close to fulfilling this dream - and tries thereby, in addition, to answer the ultimate questions of physics: the mysteries of the big bang and black holes. "On the Planck scale there is a precise, rich, and discrete structure,” says Ashtekar, professor of physics and Director of the Center for Gravitational Physics and Geometry at Pennsylvania State University. The Planck scale is the smallest possible length scale with units of the order of 10-33 centimeters. That is 20 orders of magnitude smaller than what the world’s best particle accelerators can detect. At this scale, Einstein’s theory of general relativity fails. Its subject is the connection between space, time, matter and energy. But on the Planck scale it gives unreasonable values - absurd infinities and singularities. -

Physics Needs Philosophy. Philosophy Needs Physics. Carlo Rovelli
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PhilSci Archive Physics needs philosophy. Philosophy needs physics. Carlo Rovelli Extended version of a keynote talk at the XVIII UK-European Conference on the Foundation of Physics, given at the London School of Economics the 16 July 2016 Published on Foundations of Physics, 48, 481-491, 2018 Abstract Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I maintain that the current anti-philosophical ideology has had damaging effects on the fertility of science. I also suggest that recent important empirical results, such as the detection of the Higgs particle and gravitational waves, and the failure to detect supersymmetry where many expected to find it, question the validity of certain philosophical assumptions common among theoretical physicists, inviting us to engage in a clearer philosophical reflection on scientific method. 1. Against Philosophy is the title of a chapter of a book by one of the great physicists of the last generation: Steven Weinberg, Nobel Prize winner and one of the architects of the Standard Model of elementary particle physicsi. Weinberg argues eloquently that philosophy is more damaging than helpful for physics—although it might provide some good ideas at times, it is often a straightjacket that physicists have to free themselves from. More radically, Stephen Hawking famously wrote that “philosophy is dead” because the big questions that used to be discussed by philosophers are now in the hands of physicistsii. -
Space Coast Is Getting Busy: 6 New Rockets Coming to Cape Canaveral, KSC
4/16/2019 Space Coast is getting busy: 6 new rockets coming to Cape Canaveral, KSC Space Coast is getting busy: 6 new rockets coming to Cape Canaveral, Kennedy Space Center Emre Kelly, Florida Today Published 4:04 p.m. ET April 11, 2019 | Updated 7:53 a.m. ET April 12, 2019 COLORADO SPRINGS, Colo. – If schedules hold, the Space Coast will live up to its name over the next two years as a half-dozen new rockets target launches from sites peppered across the Eastern Range. Company, government and military officials here at the 35th Space Symposium, an annual space conference, have reaffirmed their plans to launch rockets ranging from more traditional heavy-lift behemoths to smaller vehicles that take advantage of new manufacturing technologies. Even if some of these schedules slip, at least one thing is apparent to several spaceflight experts here: The Eastern Range is seeing an unprecedented growth in commercial space companies and efforts.

(Photo: NASA) NASA's long-awaited SLS, a multibillion-dollar rocket announced in 2011, is slated to become the most powerful launch vehicle in history if it can meet a stringent late 2020 deadline. The 322-foot-tall rocket is expected to launch on its first flight – Exploration Mission 1 – from Kennedy Space Center with an uncrewed Orion capsule for a mission around the moon, which fits in with the agency's wider goal of putting humans on the surface by 2024. -

Towards an Ontology of Space for GFO
Formal Ontology in Information Systems 53 R. Ferrario and W. Kuhn (Eds.) © 2016 The authors and IOS Press. This article is published online with Open Access by IOS Press and distributed under the terms of the Creative Commons Attribution Non-Commercial License. doi:10.3233/978-1-61499-660-6-53 Towards an Ontology of Space for GFO Ringo BAUMANN a, Frank LOEBE a,1 and Heinrich HERRE b a Computer Science Institute, University of Leipzig, Germany b IMISE, University of Leipzig, Germany Abstract. Space and time are basic categories of any top-level ontology. They ac- count for fundamental assumptions of the modes of existence of those individuals that are said to be in space and time. The present paper is devoted to GFO-Space, the ontology of space in the General Formal Ontology (GFO). This ontology is in- troduced by a set of axioms formalized in first-order logic and further elucidated by consequences of the axiomatization. The theory is based on four primitives: the category of space regions, the rela- tions of being a spatial part and being a spatial boundary, as well as the relation of spatial coincidence. The presence of boundaries and the notion of coincidence witness an inspiration of the ontology by well-motivated ideas of Franz Brentano on space, time and the continuum. Taking up a line of prior investigations of his ap- proach, the present work contributes a further step in establishing a corresponding ontology of space, employing rigorous logical methods.

The Right Rocket for the Job: Small Launch Providers Target Small Satellites
The Right Rocket for the Job: Small Launch Providers Target Small Satellites An STS Research Paper presented to the faculty of the School of Engineering and Applied Science University of Virginia by Gabriel Norris May 11, 2020 On my honor as a University student, I have neither given nor received unauthorized aid on this assignment as defined by the Honor Guidelines for Thesis-Related Assignments. Signed: _________________________________________________ Approved: _______________________________________ Date ________________________ Peter Norton, Department of Engineering and Society 2 The University of Virginia Department of Mechanical and Aerospace Engineering has its first satellite, Libertas, now in orbit and plans to launch two more within the next three years. This sudden activity is representative of the vastly increased smallsat1 launch cadence by a variety of groups around the world. The trend is facilitated by the reduced cost and relative ease of assembly conferred by CubeSats, which collectively make up 70 percent of satellites launched today (Halt & Wieger, 2019). Startups, underdeveloped countries, and universities that, just ten years ago, would have been incapable of any kind of space mission are now launching several. From 2012 to 2019, 663 CubeSats were manufactured by private companies, nearly 300 by governments or militaries, and 371 by academic institutions. Yearly satellite launches have increased six-fold in this time (Halt & Wieger, 2019; fig. 1). This marked increase in customers underscores a sociotechnical problem in the rocketry industry: most rockets are fairly large and cater primarily to large satellites, leaving behind a large number of customers in the smallsat domain. Satellites broadly fall within four categories of use: remote sensing, communication, technology demonstration, and scientific investigation. -
