joseflt Posted July 13, 2016 Share Posted July 13, 2016 Hi everybody, I do not know who can help me? I have a very simple issue but, I think we need to solve it before to advance iI have created a new model but are not complete I do not who can help me? One issue it is with pi : 3.1415 , on geometry are ok but on physics i think i am not sure are wrong Becuse geometry are from the geocentric model and I think I am not sure something diferent , a universal answere, my point of view We can not use PI on high speed and low speeds, I do not know if you can imagine a circle going to 1/2 speed of light or slow speeds where circles deform. What are you think? Jose Leal Link to comment Share on other sites More sharing options...
imatfaal Posted July 13, 2016 Share Posted July 13, 2016 Why do we have to vary pi? A vague feeling of disquiet is not enough ! Moderator Note And as this is a speculation rather than Science News I am going to move the post to the correct forum Link to comment Share on other sites More sharing options...
swansont Posted July 13, 2016 Share Posted July 13, 2016 If we are in a regime where circles deform, isn't the problem that you no longer have a circle, rather than pi being wrong? Link to comment Share on other sites More sharing options...
imatfaal Posted July 13, 2016 Share Posted July 13, 2016 If we are in a regime where circles deform, isn't the problem that you no longer have a circle, rather than pi being wrong? If you have a (very large circle) and you take it close to a (fairly small) black hole keeping the line which passes through the centre of the circle and is perpendicular to the the plane of the circle pointing directly at the blackhole would you not end up with a case in which you still have a circle but that to travel across its diameter you have to travel a greater distance than travelling around its circumference / pi. I realise it is extreme and silly - but the attraction at the centre of the circle will be greater than at the edges because it is marginally closer to the centre of the black hole(tidal forces); in terms of geometry is this not similar to saying that path for a photon/test mass to cross the diameter would be curved. If i haven't got my terminology wrong: this would be the intrinsic curvature version of what with extrinsic curvature we see as the difference between a great circle route between washington and london and the shorter direct route through the earth's crust. [mp][/mp] Sorry - the whole point of the above ramble was - is this not still a circle; but one that the ratio of diameter to circumference is no longer pi Link to comment Share on other sites More sharing options...
John Cuthber Posted July 13, 2016 Share Posted July 13, 2016 Becuse geometry are from the geocentric model... But geometry isn't from geocentrism and pi isn't just from geometry. 2 Link to comment Share on other sites More sharing options...
