What is it, far as the topics covered above, for which you are seeking an informed, scientific explanation?
If you have any knowledge, at all, regarding the Sciences; you must be aware, that we only, "know" what comprises about 4% (matter AND energy) of this entire universe.
Of that 4%: there are very few things that we can consider categorical, "fact" or, "Law". The rest is all theory, over which Physicists and some of the greatest minds the planet has ever known, have argued since 1927 Vienna and the fifth Solvay Conference on Physics.
If you're actually interested in some information, regarding the 20th Century's theories (ie: Electrical Theory (QED), semiconductor permittivity, wave/ particle duality, etc) and how those might explain some of what hear from our systems: we're on.
If you're just another naysayer, looking for the typical, inane, uneducated argument: forget about it!
Either way: happy listening!
