The twin paradox revisited
harry wrote in sci.physics.relativity: wrote in message ups.com... When I previously had access to the internet about ten years ago I expressed interest in this topic and was informed that a space traveller does not physically age at a slower rate but that his earth- bound twin physically ages at a faster rate and only during the period of acceleration following turn around. Is this idea still in vogue? Has it been published in any peer reviewed journal? No. That idea may stem from Einstein's 1918 GRT solution of the twin paradox, but it is not widely accepted: "induced gravitational fields" are messy. See for example a discussion of a few years back: http://tinyurl.com/2mu4jv The reference is good: there is a quotation in it that shows how students at the University of Illinois, Urbana-Champaign are converted into zombies: Tom Roberts: "Physics is LOCAL -- don't worry how the distant twin is aging during the trip; all that can be tested experimentally is the comparison of their clocks when they rejoin; compute that correctly and be happy." Tom Roberts is the Albert Einstein of our generation: http://www.iit.edu/~bcps/database/se...culty_web_page Pentcho Valev |

The students aren't being converted into zombies. The professor is merely instructing them on how to believe in a perfect mathematical fantasy.

But I made a mistake - Tom Roberts does not convert students at the University of Illinois, Urbana- Champaign into zombies. Rather, he converts students at Illinois Institute of Technology, Department of Biological, Chemical, and Physical Sciences, into zombies: http://www.iit.edu/~bcps/database/se...frontend/index But he will convert all University students into zombies sooner or later - nothing can stop him.

The University of Illinois, Urbana-Champaign is one of the best schools in the U.S. (and the world). What is your highest level of education? Do you lie about your academic qualifications like Androcles does? Pentcho Valev- Hide quoted text - - Show quoted text - |
