Physics challenged

    how serious is the challenge to physics to explain the causes behind every force that we know of?and is physics trying to get over its scientists differences of approaches in this regard?

    Could you clarify your question? It can be read several ways. Scientists are always working to better explain the laws, but not sure what you mean by "causes behind the forces". For example, gravity is well explained by General Relativity.

    thank you dr chinese,i mean,the causes or the initiators ,the mother force if you like,that has caused the laws to exist?,the initial cause or determinent behing them,could these forces be relegated to a single creating force?if yes why and if no why is that.

    At this point, the standard model has 3 quantum forces (strong, weak, electromagnetic) plus general relativity (gravity). I don't see that there is much that really explains why the laws of physics are as they are, nor why there is something rather than nothing. Most of this is currently considered more or less as free parameters that could have conceivably have occurred another way.

    I think you are talking about what Paul Davies calls "ultimate explanation". Why the universe formed and operates the way it does. And could it have been any different.

    thanks freeman,is there any online resource for the ultimate explanation?

    in a written form

    The author mentions a Mother Force', and a 'Single Creating Force'.
    Interestedman, can you please be more specific with regard to what you are looking for? Do you want us to tell you that there may be a single, 'Almighty' force of some kind? A Force that "creates all things", perhaps?

    dear anderson,thanks for the reply,i am not looking for one answer rather than another,i am only asking about the cause of the laws of physics,can you enlighten me with how physics is close to an explanation,that is all,thanks.:smile:

    dear dr chinese,what do you mean "could have conceivably have occurred another way",thanks.

    There is no underlying physical law that prevents them from being different to they way they are (i.e. they could have different strengths), that we know of that is.
