Greetings from Goa, India, on the shores of the Arabian Sea.
I am here at the International Conference on Gravitation and Cosmology, hosted by the Indian Association for General Relativity and Gravitation and the International Centre for Theoretical Sciences, part of theTata Institute of Fundamental Research. Goa has changed a lot since the first ICGC meeting here in 1987, but the beaches and hospitality still make for a most pleasant spot to talk about physics.

In the next week or two, I hope to post more about the events and talks here at the conference. I am here in Goa representing FQXi, because we hope to expand our connections to the research community in India. A quick look at our Member list shows that we have just two members currently based in India, despite the many researchers here studying foundational questions.

My task here is to find out how FQXi can best help the Indian research community. One of our strengths as a funding agency is the flexibility of our funding -- we can support projects around the world, and we can support projects of many forms and function. Case in point, we were able to help with the conference by supporting the attendance of members of the Indian press. The worldwide public has a growing interest in science, and the attendance of the press at meetings like this help spread the word about good science.

Stay tuned for more.

Dear Brendan Foster,

Obviously you are busy at the moment, but can you say whether FQXi is planning more essay contests, and when we might hear more about this?

Thanks, and have fun.

Yes, we will have another contest soon, and we plan to have them regularly on into the future. I can't tell you yet the topic or the exact dates, though.

I think the OPERA experiment makes the topic self-evident:

"Is Einstein's 1905 light postulate true?"

Dear Brendan,

I agree with Pencho, that superluminal neutrinos, now seen by Fermilab, MINOS, and OPERA -- twice -- raise probably the most fundamental questions in physics at this time. Also, while not participating in much of it, I've noted many relativity discussions on FQXi in the last year. Many participants seem to be well informed and to have interesting ideas.

Any hints about when and what?

Pentcho,

Hartnett is on the same list as is Merryman. I just wonder why his Proposal for a New Michelson-Morley Experiment was perhaps not published in Phys. Let. 2002.

This is relevant to the link posted by Eckard.

Max Tegmark's question (something like) Why can't /doesn't space snap like an elastic band? Is a good one for cosmologists and other's to consider.

In the explanatory framework set out on FQxi blogs the observed "objects in space" image is produced by the observer from received data. It ( the observed objects in space ) is not the foundational source objects that produced the data. So the supposed expansion is IMO likely to be due to the relationship of the Earth Object with the Data pool in which it is immersed and the fact that it is not stationary within it but following its own Lagrangian (I'm learning) trajectory through the Object universe.

Which gives that “looking out of the rear view window appearance” and is probably the foundation cause of curvature of space- time, as the Data pool is distorted by the movement of the massive body through it. Distortion of the medium in the foundational reality (not space-time), in which the data exists, by a massive body could give a path for a neighbouring body to follow minimising its potential energy by orbiting the other object. The foundational source of gravity.

The diagram shows the Object reality and Data pool as separate as the data pool is a subset. It does not show them mixed together and interacting as they are, only that they are parts of the same reality. As well as the structural arrangement given it is necessary to recognize that it is not static but there is continual change giving new events and relationships between foundational objects, new generated data, and new observed outputs.

The actual Object universe of source objects simultaneously existing with the Earth in the same unitemporal Now is not observed and so is not observed to be expanding and there is no reason to assume that it is. Far more likely to be in a stable state of continual recycling and feedback loops; balanced erosion and deposition, growth and decay or destruction etc. etc. Nowhere for the matter and energy to go other than elsewhere in the Object universe. No closed systems but many different systems that may seem to operate separately but are all open to influence from outside.(Can be nudged back into action when they slow.)

The error is thinking that the observed image of the Universe is the Entirety of the Universe and the Objects themselves rather than just data emitted or reflected from them later formed into observable output, the Image reality.

Dear Eckard,

what do you think of the solution offered? Surely it is good to have an explanatory framework that fits the experimental evidence, answers questions, overcomes paradoxes and allows QM and space-time relativity to co -exist as different facets of the entirety of reality. Though the big bang, inflation and space-time continuum from bang to crunch or whatever will have to go as incompatible with it, it will fit with what the other scientists, like those signing the petition, are finding which is results also incompatible with the big bang scenario.

Gravitational Redshift Means Decreased Speed of Light

The speed of light varies with the gravitational potential, according to both Newton's emission theory of light and Einstein's general relativity:

Gravitational Redshift Means Decreased Speed of Light II

http://www.wired.com/wiredscience/2011/09/galaxies-einstei
n-relativity/

"Galaxy Clusters Back Up Einstein's Theory of Relativity. (...) The researchers, led by Radek Wojtak of the Niels Bohr Institute at the University of Copenhagen, set out to test a classic prediction of general relativity: that light will lose energy as it is escaping a gravitational field. The stronger the field, the greater the energy loss suffered by the light. As a result, photons emitted from the center of a galaxy cluster - a massive object containing thousands of galaxies - should lose more energy than photons coming from the edge of the cluster because gravity is strongest in the center. (...) The effect is known as gravitational redshifting."

In fact, Einstein's general relativity, just like Newton's emission theory of light, predicts that, as light is escaping a gravitational field, it will lose SPEED. That is, the redshifted light Radek Wojtak refers to is one having a speed lower than c. However if he had said that in his paper, neither Nature nor any other "respectable" journal would have published it. Paradoxes in Einsteiniana's schizophrenic world: Never say the truth, even if it comes from Divine Albert! And if Radek Wojtak had hinted at some analogy between the gravitational redshift he measured and Halton Arp's "intrinsic" redshift, he might even have become an unperson, like Halton Arp:

George Orwell: "Withers, however, was already an unperson. He did not exist : he had never existed."

Pentcho,

"In fact, Einstein's general relativity, just like Newton's emission theory of light, predicts that, as light is escaping a gravitational field, it will lose SPEED."

This statement is not an empirical fact, it is your theoretical interpretation. It may be a theoretical interpretation made by others, but, it is not an empirical fact.

Gravitational Redshift Means Decreased Speed of Light III

Sooner or later cosmologists will have to face the fact that ANY redshift means decreased speed of light:

http://www.sciscoop.com/2008-10-30-41323-484.html

"Shine a light through a piece of glass, a swimming pool or any other medium and it slows down ever so slightly, it's why a plunged part way into the surface of a pool appears to be bent. So, what about the space in between those distant astronomical objects and our earthly telescopes? COULDN'T IT BE THAT THE SUPPOSED VACUUM OF SPACE IS ACTING AS AN INTERSTELLAR MEDIUM TO LOWER THE SPEED OF LIGHT like some cosmic swimming pool?"

always a platform checked by a team ! Zeeya, are you sure that all the members are integre ???

You know it exists bad and good people in all system. I am persuaded that unfortunally it exists sevral persons with bizare comportments inside the fqxi sphere. Mr Tegmark and Mr Aguire must take their responsabilities. FqxI is better than this team. In fact, they are not generalists , so they utilize your platform with algorythms of selectivity and superimposings. The pictures so are easy to check. I find this strategy by these persons very sad.

Fqxi must take its responsabilities, it exists two teams inside your intrinsic fqxi sphere. It is better to check the persons than to check the pc of people at my humble opinion. These persons are not on the rational way, they do not understand the generality of the universal sphere.

Fqxi do not really need of these persons, Fqxi needs simply to be universal and foundamental. the selection of the members is not a simple play of pseudo politeness and pseudo complemenatrity between institutes.

Hi Steve,

I don't know which members you are concerned about (and it is probably better NOT to name them in a public forum). Members are added according to the steps outlined here: http://fqxi.org/members. As far as I know, none of them have had their honor or integrity questioned -- though their ideas in physics are open for debate.

Well Zeeya, say to Brendan that a young belgian has found for the next conference about gravitation, but perhaps he prefers speaking about iorrationalities of extradimensions of nothing for nothing.perhaps even that the sciences have lost their foundamentals also.And we pay what? their travels of course and for what, nothing of course.Still a lot of monney for nothing, just for their vanity and their travels.

I don't say that all the members are like that.I am saying simply that it exists real searchers and on the otehr side the frustrated. Now of course all persons can understand that the world is difficult, but the truth has its limits.

For the threads, don't take me for your puppet.It is me who plays !And don't say me that the threadfs are real like my net.Let me laugh.Just because several frustrated have created a kind of team against me. Frankly they have nothing understood.
