    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    No. http://en.wikipedia.org/wiki/Cosmic_microwave_background_radiation The lambda term in Einsteins equation is a special form (constant*g_mn) of an energy density (energy-stress-tensor). Thus lambda corresponds to an engery contibution. This energy curves the space, i.e. it has a...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    Of course this is well known. the measured lambda is homogeneous - i.e. it is not a function of space. The value of lambda is a global quantity - it is e.g. measured by observation of the homogeneous, global cosmic background. There is no reason caused by observation to assume that lambda is...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    Thanks for the links. At the moment there only heavy math articles. A much of topology is needed - difficult to understand for many physicists - including me :-) Maybe the new book of Torsten and Carl Brans will help: https://www.amazon.com/dp/981024195X/?tag=pfamazon01-20 best regards...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    Hi Mike, nice to read you. Sorry, I think I don't understand your point. Could you explain: what is the calculated value - lambda_vacuum ? what is the globally measured value? As I understand is lambda a homogenous effect caused by an energy contibution. If your contribution is to big no...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    Thanks for this interesting info - could you post the arxiv link. I'm not engaged in the E_v debate , I think it is a inner-QFT problem and it could be disappear if we get a better understanding of the other great QFT-problems (singularities, notion of spacetime point, relation to GR). But...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    You are absolutely right and we are aware of the risk that a tiny mistake could make the result totally wrong. But we state a hypothesis not a truth. The hypothesis has to output the right values found by observations and it has to survive. This paper is restricted to the global structure and...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    Dear R.X. Nice to see you let your BS-style behind you. Now I very understand the core of your problem with our approach. It is true, QFT assumes the origin of lambda is the vacuum energy - but this is a assumption (like our assumption that the source is geometrically). The vacuum energy...

    Thanks Marcus, it is great to could be here. I very like the discussion and the open mind in the forum. I like even the hard but objective criticism (the careful style) it helps very much (in our last paper some errors could be corrected by this clear mind of the forum). Thats why we post the...

    Graduate How Does Differential Geometry Help Calculate the Cosmological Constant?

    I would very appreciate any constructive criticism, but your "statement" is nothing else then unsubstantial polemics. I am not willing to discuss at this level. In case you should have read the paper and there is any well-founded criticism - let me know. Helge

    It seems that arXiv.org update the list sunday night. In the meanwhile you can get the paper here http://www.qc.fraunhofer.de/qg/0609004.pdf" best regards helge

    Graduate Rosé and A-M: Geometrization of Quantum Mechanics

    Dear Mike2, dear selfAdjoint this was an interesting discussion! At the first sight it seems like an easy question about the "Fahrstuhl" experiment and we can give a quick answer. But we discuss about your problem a long time and realizing: it is not straight forward. Ok, what is the problem...

    Graduate Rosé and A-M: Geometrization of Quantum Mechanics

    Dear Mike2, no, we have not. At this stage the approach can not handel such questions. (By the way: My opinion is, that a black hole is a infelicitous defined model (but a solution of the E.eq.) and the epistemological problems are too deep. Thus I am not very interessed in black hole...

    Graduate Rosé and A-M: Geometrization of Quantum Mechanics

    Every diff. manifold has a DS - it is simply the equivalence class of its allowed atlases. So it is not a additional structure but in many cases you don't have to care about the DS. For instance in 3dim you have only one DS, i.e. there is no structure which we could use for physics. Only in 4dim...

    Graduate Rosé and A-M: Geometrization of Quantum Mechanics

    Dear Careful, we appreciate your comment. We are also happy to fix with your help this bad error in the definition of \Sigma. Thats why we will not give a quick answer about your question related to **COMPLEX curvatures** now, give us some time to carefully check this. Question: What would you...

    Graduate Rosé and A-M: Geometrization of Quantum Mechanics

    As I said, we have no eq. at the moment - only conjectures - but I'm sure you would say to that: speculative, no examples, etc... So it is better we first complete the next paper which will deal with the dynamics of DS and then start the discussion. I hope we will manage your good advice and put...
