Overview

Sean Carroll's 2013 Fermilab Users Meeting lecture on particles, fields and the future of particle physics. He explains that particles are vibrations in underlying quantum fields and touches on the Higgs, neutrinos and dark matter.

> Every point of Universe contains infinite number of small, even infinite small, particles. What "particles"? [VIDEO] (really worth it! Watch at 1.5 times speed) and [LINK] (reading the discussion is useless though without understanding at least what is presented in the above lecture)

There are many different ways of looking at quantum mechanics, so here is one way of answering your confusion. Probably the standard way of looking at quantum mechanics right now is quantum field theory. In quantum field theory, you give up the notion of "particles" and instead view them as vibrations in fields. Once you do that, it makes more sense that these "particles" can turn into other particles, be absorbed or emitted by other particles, or split. Here's a video of Sean Carroll talking about it, roughly 28:00-33:00. [VIDEO]
