The universe’s composition is largely misunderstood by common perception. While it might seem that the universe is primarily made of atoms, this is not true [00:04:29]. Most of the universe is, in fact, dark [00:04:36].
Dark Matter
Dark matter is a new substance that does not consist of atoms [00:04:38]. It is believed to constitute the majority of matter in the universe [00:04:27]. This substance can be studied using telescopes and other instruments, indicating it is not merely science fiction [00:04:58].
String Theory and Dark Matter
String theory proposes that dark matter is created by “notes higher than electrons and protons” in its “music” of vibrating strings [00:04:12]. In this view, dark matter represents another “octave of the string” [00:04:42]. String theory is currently the only theory developed enough to explain not only fundamental particles like neutrons and protons, but also dark matter [00:05:07].
Dark Matter as Evidence for the Multiverse
The existence of dark matter could provide concrete proof for the multiverse theory, which posits an infinite number of universes [00:00:11], [00:04:06]. The number of universes and forms of matter are considered infinite, with dark matter being one such form [00:04:51].
