It seems to be a law of nature that all things consist of smaller, less complex things: fundamental particles are (comparatively) simple. They react to form atoms, atoms form molecules, molecules form different chemicals, these chemicals also reach with each other to form cells, minerals, etc. Millions of cells form plants and animals (creatures much more complex than these cells, and definitely more complex than a quark)... all of these things form planets and stars, these form solar systems, galaxies, groups of galaxies, etc. and finally the known universe. but would it make sense to assume the it doesn't get any bigger than a universe or any smaller than a quark? wouldn't it logically follow that many universes, and universe-like "particles" form something much greater, and so on... the same being true backwards (that fundamental particles are also made up of infinitely simpler particles themselves)? I don't know, ever since I was a kid this is the way I saw it... that, while this universe might be finite and might eventually "die", all of our observable laws so far seem to point towards a different kind of infinity (infinity in the form of increasing/decreasing complexity). I only have a superficial knowledge of physics, so I would like to know if there is any law that would prevent this from being true. If not, I'm also interested in knowing if there are any other people or scientists who share this view.
