I think the most interesting thing about the Universe is that it maybe actually be made up of vibrating strings, as theorized in String Theory, or more recently known as M-Theory, instead of Point Particle Physics which states the Universe is made up of point particles such as atoms particles. The experiments done with quantum mechanics have yet to be disproved, while the ones in the standard model are riddled with anomalies, the problem is, is that at this point in time, we cannot prove beyond mathematics all the problems associated with String Theory, therefore we cant yet replace point particle physics with it yet. One day maybe, when the science catches up with the math. Maybe then.
