That was bold (or maybe foolish) of you! I would be reluctant to open a Word file posted by PF member that I respected & trusted, let alone a newbie with 12 posts to their name.bcrowell said:I took the time to download and view the Word file, but you will probably get more responses if you post the text directly.
DanRay said:Yes you are wrong for a very simple reason. Special Relativity as it is almost universally understood created the whole idea of spaces, times, distances and speeds that deviate from the Galilean standard ideas by virtue of use of the Lorentz Transformations in their simplest form. In some of your arguments and some of your math you have drifted into conventions that didn't exist for special relativity which began from a Galilean framework that was modified by the effects of the Lorentz Transformations. Your "four space" with invariant time is an oximoron within either SR or GR. SR demands variable time in some instances when Lorentz equations are used and the four dementional space-time continuum is a product of GR. Your "four space" is a non-idea that doesn't exist in any known system.

The equations in the Word file didn't come through for me; this is another reason why it would be better to post here. (You can use latex math inside special tags, e.g., I can do [itex]E=mc^2[/itex]. To see how this is done, click on the Quote button for this post, and it will show you the way I entered the equation.) In general, it's not safe to assume that everyone on the internet uses the same word processor you do.
I wasn't able to figure out what your post was really trying to say, based on a quick reading. You might want to make clear whether your idea predicts different results for experiments than SR does, or whether it's just meant to be a derivation of SR from an unusual perspective.

Thanks for the reply. Doesn't it bother you that Special Relativity (SR) has observers, moving with respect to each other, exist in different Universes? In my note I make up a space with four-space coordinates and a universal time coordinate. This is not the space of SR nor is it the space contemplated prior to SR.

Greg Bernhardt said:One of the main goals of PF is to help students learn the current status of physics as practiced by the scientific community; accordingly, Physicsforums.com strives to maintain high standards of academic integrity. There are many open questions in physics, and we welcome discussion on those subjects provided the discussion remains intellectually sound. It is against our Posting Guidelines to discuss, in most of the PF forums or in blogs, new or non-mainstream theories or ideas that have not been published in professional peer-reviewed journals or are not part of current professional mainstream scientific discussion.
edpell said:Sylas, OK here is a quote from full tenured professor of Physics Columbia University Brian Greene's book "The Elegant Universe" page 50, "Here's the leap: Einstein proclaimed that all objects in the universe are always traveling through spacetime at one fixed speed--that of light." This is accepted canon.
gamburch said:With respect to sylas, I cannot help but thinking that this is just a little fun about an interesting idea. I understand that original work should, perhaps, be peer reviewed, but in a forum, if cannot one throw somethig against the wall, where can one?
The Galilean universe refers to the physical laws and principles proposed by Galileo Galilei in the 17th century. It is characterized by the principles of relativity, which state that the laws of physics are the same for all observers in uniform motion.
The Galilean universe is based on the principles of relativity, while the Newtonian universe is based on the laws of motion and gravitation proposed by Isaac Newton. The main difference is that the Galilean universe does not account for the effects of gravity, while the Newtonian universe does.
While the Galilean universe may not accurately describe the physical world at all scales, it is still relevant in modern science as it laid the foundation for the development of the theory of relativity and our understanding of the laws of motion.
In the Galilean universe, time is considered to be absolute and universal. This means that all observers would measure the same amount of time for an event, regardless of their relative motion. However, this concept was challenged by Einstein's theory of relativity which proposed that time can be influenced by the observer's frame of reference.
The Galilean universe is a theoretical model that is based on the laws of physics and has been supported by many experiments and observations. However, it is not considered to be an absolute truth and can be disproven if new evidence or theories emerge that contradict its principles.
