History of the Visual Physics Project
I had the basic idea on which the Special Relativity Simulation is built many years ago, back in 1971, when I was 17 years old. At that time I heard of "curved spacetime" for the first time, and as I was trying to understand what it is I had a very clear picture of a vertical time axis and, perpendicular to that, a horizontal space axis; and the accompanying thought that if all points of the space axis are projected on the same point of the time axis (that is, if the space axis is perpendicular to the time axis, which means that all its points have the same time coordinate), this spacetime is non curved (it is Galilean). If, however, the points of the space axis have different projections on the time axis (which means they have different time coordinates), this spacetime can be "curved". (Although there is also the theoretical case to be a straight line that meets the time axis not perpendicularly but at an angle.)
This idea remained in the back of my mind ever since, but I had no way of checking if it is correct or not. I have been using computers in my work since the early days of DOS. My first PC was an Amstrad 1512 with BW monitor and two 5" drives for 512K floppy disks, and of course those days our word-processing program was Volkswriter. As time went by, PCs got better, and at some point I got my hands on Excel. I realized that it would allow me to check my idea, but I had to wait again until I could learn to use it. Of course, all this was slow progress as I could only work on this on my spare time, which, as any freelancer knows, is practically nonexistent. After I familiarized myself with Excel, I was able to graph my idea and I saw that most probably it was correct. However, the picture was far from clear.
The big break came when I was googling for a simulation software that would allow me to put a working simulation on a web page, and I came upon Easy Java Simulations (Ejs for short), a program that is part of the Open Source Physics project and was built by Dr. Francisco Esquembre, Assistant Professor of Mathematics at the University of Murcia, Spain. This solved the problem of presenting my ideas in the form of a web simulation (something that you cannot do with Excel or other even more advanced programs), and that made me decide to have a go at trying to build a simulation that would present my ideas.
The same day, August 30, I informed Dr. Esquembre about the simulation, and I posted a short message at sci.physics.relativity and sci.physics.research (it appeared on September 1 and 2 respectively), where it attracted a lot of visitors from universities and research centers, as well as a dismissive comment by an avid poster of these groups.
During September 2005, I started sending emails to known physicists, asking them to look at the site. I will not mention any names, I would not want to embarrass any of them http://www.visual-physics.com/blog/icons/smile.gif. I started with 5 isolated people. Only one of them visited the site for 5-6 minutes, and then answered my email without commenting on what I am proposing. He just said to let him know if I do a general relativity simulation. (I have to note though, to his credit, that he is one of the most famous, and even this was more of a response than I got from most other physicists, who did not bother answering.) Then I emailed some of the physicists who have contributed to Living Reviews in Relativity, but I had no answer.
I realized that what seemed like obvious conclusions to me may not be as obvious to others, so I started working again on the simulation. I built SpecialRelativityV2, that also depicts the axes (the coordinate system) of the body of each system, as well as the axes calculated on the basis of the Lorentz transformation, and it shows, convincingly I think, that the latter are produced by the projection of the axes I propose for the Moving Body (or Moving Observer, if you like) on the x axis of the Stationary Body (or Stationary Observer). And this proves that the phenomena of Special Relativity are due to the curved expanding universe. I uploaded this version on October 30, 2005, and you can still see it here.
On the same day I sent a new email through a mailing list to a number of physicists, again most of them authors who had contributed to Living Reviews in Relativity, as well as to the 10 editors of the journal. Again I had a few visits but no response. Also I had several hits that were not from universities, so that I do not know who these people were. Then I started having hits from some group discussion in Orkut, which I could not follow since I am not a member. And so at some point in November of 2005 I closed the site putting up a blank homepage that said that access to the site has been restricted.
For a while I stopped thinking about this project. However I could not abandon it. Besides, I had a few more simulations that I wanted to build, as mentioned on the homepage of the site, on the basis of some other ideas I had had in the meantime. I decided to write a paper with the basic views presented by the simulation and try to deposit it at arxiv.org or publish it somewhere. I wrote the paper and I opened again the site. I also made a minor correction to the simulation, that brought it up to the 2.1 version. On May 17, 2006, I uploaded the paper to arxiv, and on May 19 it was rejected. The reason was that, since I have no institute affiliation, I should at least have an endorsement.
I made a new version of the paper with black & white figures and I submitted it to IOP on June 4, 2006. It was rejected on June 5 ("we do not publish this type of article in any of our journals"). On the same day, June 5, I submitted it at the PhilSci Archive. It was rejected on June 7 ("lies outside material suitable for our philosophy of science preprint archive").
Since I was obviously considered a crackpot, I decided to try my luck among others who have unconventional views. So I sent an email to a "maverick" professor at Cambridge, and to two proponents of Euclidean Relativity. The professor downloaded the paper, but did not answer. The same with the first of the "Euclideans". The second, however, wrote right away with his objections, explaining why what I am proposing is impossible. (I was not convinced.) But he also made a valuable comment, that the simulation is not very intuitive and that I should add some buttons that would play some predefined simulations. I implemented his suggestion building the "running" simulation that shows the formation of the axes in "real time". Also on June 7, I submitted a post to the Independent Research forum of Physics Forums, about which I have not heard yet as of today.
On June 8 I sent again an email to the authors of Living Reviews in Relativity about the paper, without any response. I started sending emails at two or three people at a time. Some came and downloaded the paper, but no one answered. On June 12 I emailed a physicist at CERN who is also working on Special Relativity. He downloaded the paper but disagreed with my conclusions and stated that he cannot endorse it for arxiv. His objections also did not convince me, since he had not viewed the simulation. What I am proposing is very different from the way people are used to think about Special Relativity, and it seems that this makes the whole thing incomprehensible.
So, as a last step, I decided to make a blog so that visitors would be able to leave their comments even anonymously, if they do not want to use email. Later, I was able to implement the idea of this site that I had for some time, and which, besides the blog, also has a forum and a wiki for the development of the theory.
I first turned to Community Server, a windows based program that offered blogs and forums. The problem was that it did not offer content management, and it did not have a wiki yet. The development of a wiki plugin had started, but it was taking forever.
I started looking around for other options in the LAMP platform (linux-apache-mysql-php). The main solutions were Xoops, Drupal and Mambo Joomla. When I saw that Joomla what an extension that integrated MediaWiki, I knew I had found the ideal solution. And this more or less brings this account up to date.
