<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>First, the Standard Model does not attempt to explain gravity, and it is unknown how to combine quantum field theory which is used for the Standard Model with general relativity which is the best physical model of gravity. This means that there is not a good theoretical model for phenomena such as the early universe</DIV></p><p>This is correct in that it is certainly well known that quantum field theories do not include general relativity and that attempts to develop a quantum field theory that does include general relativity have not been successful. In particular attempts to build such a theory have resulted in theories that are not renormalizable, hence tend to be plagues by infinities that don't go away. That issue is quite well known and is one reason for the large amount of research into unification of quantum field theories with relativity -- loop quantum gravity, string theories and their successors, etc.</p><p>That is no reason to reject the standard model in its entirety anymore than one simply rejects Newtonian mechanics due to the advent of relativity. Both provide excellent predictions so long as one recognizes the domain of validity of the theory.</p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> For example, the theory contains many seemingly unrelated parameters of the theory i think 21 in all (around 18 parameters in the core theory, plus G, c and h there are believed to be an additional 7 or 8 parameters required for the neutrino masses, although neutrino masses are outside the standard model and the details are unclear). Research also focuses on the Hierarchy problem (why the weak scale and Planck dimensions are so disparate), and attempts to reconcile the emerging Standard Model of Cosmology with the Standard Model of particle physics. Many questions relate to the initial conditions that led to the presently observed Universe.OHHH YEAH & About 85% of the mass of the universe is yet unaccounted-for by any of the particles in the Standard Model -- missing "dark matter". If i make a theory that accounts for only 15% of things would you believe it?ITS non-sense non-imaginative and scrambled information just thrown together <br />Posted by dabiznuss</DIV></p><p>As noted above the standard model does have its limitations and quirks. Some of your objections are valid and are well known. Physics is a subject with a rich body of on-going research, and much of that research is directed towards a unification of particle physics with general relativity. But to conduct such research effectively and intelligently one must understand the standard model and general relativity and work from that knowledge to develop something more complete.</p><p>Your statement that the model is nonsense, is a statement that simply reeks of ignorance and lack of understanding of the process of scientific research. What lacks imagination is your statement and not the standard model, and certainly not the on-going research in the fundamentals of physics. In point of fact a great deal of imagination and inventiveness went into the development of quantum field theories and the standard model of particle physics. Your assertion to the contrary is somewhat insulting to the body of very talented and very imaginative physicists who developed that model, but it is more a comment on your own lack of imagination, knowledge of physics, capability to do or even understand research, and general ignorance and lack of comprehension of things scientific.</p> <div class="Discussion_UserSignature"> </div>
