Dear Stefan,

Greetings. Thanks so much for reading my essay. I look forward to reading yours.

Thanks also for telling me about Tumulka's work, which actually I am acquainted with. We discuss it briefly in our review article arXiv:1204.4325 (Section II). It is promising undoubtedly; I think the challenge is to include interactions.

My best wishes,

Tejinder

Dear Robert,

Thank you so much for reading and appreciating my essay. That is very kind of you.

Let us hope that there will be an experimental breakthrough in the next few years, which can tell us decisively about the validity of the CSL model.

My best regards,

Tejinder

Thanks TP,

I understood a few things more about CSL. In my mind, it was always clear how time could emerge, of course from a different consideration, but not how space could emerge. In fact, often I thought of space being the only reality and everything else emerges from it. Anyway, my essay does not deal with any of such things, I only worried about the information aspect. See, I could follow yours, but I am not sure if you could follow mine with as much comfort ! May be you are a better story teller.

Amplification is understood now, but then, does it mean that all nucleons in a macroscopic body could be considered as forming a single entangled state? The answer you already gave as yes.

Dear Tejinder,

This is a remarkable Essay, despite a bit speculative. I particularly appreciated your observations on the limitations of quantum theory. It was an intellectual pleasure for me reading your Essay, thus, I decided to give you the highest score.

By the way, today I have read also your GRF Essay in arXiv. It is another intriguing work. Maybe I will attempt to apply your new length scale for quantum gravity in my future works on my Bohr-like black hole model. Congratulations and good luck in both of the Contests. I hope you will have a chance to read our Essay on gravitational waves.

Cheers, Ch.

    Dear Prof T. P. Singh

    A short glimpse and I have a feeling I'm reading a breakthrough. I will have to go on details of the space in which TD resides.

    I have difficulty understanding one thing. I don't have any knowledge of Gauge Theory so forgive my ignorance.

    How do we form another L^2 Hilbert Space using 2 Hilbert Spaces each of two different N-particle systems? The trace operator you use hints at the quaternions, if I understood it correctly.

      Dear Ch.,

      Thank you so much for your kind remarks and good wishes, and also for seeing my GRF essay. I will be honoured if you consider this new length scale in your work. i am talking to some colleagues about looking for possible experimental tests of this new length.

      Best wishes,

      Tejinder

      Dear Dr. Malik,

      Thank you so much for your kind appreciation.

      If I have understood you correctly, can we not form the new Hilbert space simply as a direct product of the states of the two different systems?

      There possibly is a connection with quaternions, but I am not sure of this. You may want to see Stephen Adler's historical account of his discovery of TD, which was preceded by his work on Quaternionic quantum mechanics, on which he has a book.

      My best wishes,

      Tejinder

      Dear Tejinder,

      I enjoyed very much your essay, in which you discuss CSL and its emergence from TD, the proposal of suppression of quantum superposition at large scales by nonlinearity, and the relation with goals. I agree that superposition has to be suppressed somehow at higher levels, since the classical level doesn't seem to suffer from it (section |7> of my essay). In fact I have a proposal of several experiments that I hope will find some sort of superselection which I hope to suppress superposition in Searching for microscopic classical cats (although in a way compatible with both linear and a possible nonlinear formulation of QM). Best luck in the contest!

      Best regards,

      Cristi Stoica

        Tejinder,

        I hope to hear from you over on mine before we imminently have to do our final scoring. I identify some very important new physics that you're well qualified to falsify.

        You know the problem; "Standard quantum theory has no answers. Do these unanswered questions call for new physics?" Not t really entirely 'new' either.

        Very best

        Peter

          Dear Tejinder,

          very interesting essay with provocative thesis (quantum theory as emergent theory) But I like it very much (also along the line of my thinking).

          Therefore you got a high mark from my side.

          Maybe you are also interested to read my essay? This time not bout exotic smoothness and the fractal spacetime.

          All the best

          Torsten

            Dear Cristi,

            Greetings, and many thanks for your kind comments.

            Thanks also for pointing to your essay, which actually I had already read (and rated) and enjoyed reading, though I did not leave a comment :-)

            Best,

            Tejinder

            Dear Peter,

            Greetings. I had already read your essay with pleasure, and rated it too. Though I have not left any comment.

            And I agree! QM needs something done to it! :-)

            My best wishes to you for success in this contest,

            Tejinder

            Dear Torsten,

            Many thanks for your kind remarks on my essay.

            Best,

            Tejinder
