Clearly you are not a physicist. Just because you don't personally know sth does not mean it's not there or being worked on.
The theory of relativity has quite clear thoughts about why there is a "speed limit". Entire branches of physics ponder about why and when electrons and other particles came about.
The shrugging "Don't know, we just noticed it." that you ascribe to scientists' reactions does not match reality.
