Dark Matters About Primordial Black Holes

The Universe is a bewitching, mesmerizing mystery, an almost unfathomable puzzle that cannot be simply ignored, as it sings its haunting siren's song to those who seek to understand its weirdness. Black holes are some of the weirdest denizens of our bizarre Cosmic Wonderland, with gravitational forces so extremely powerful that absolutely nothing, nothing, nothing at all--not even light--can escape from the furious, fatal claws of these strong gravitational beasts. Our Universe is thought to have been born in the wild inflation of the Big Bang almost 14 billion years ago, when it began as an incredibly dense Patch, smaller than a proton, to experience exponential expansion--ballooning to attain macroscopic size in the smallest fraction of a second. Primordial black holes are hypothetical objects that may have formed as a result of the extreme density of matter present during the Universe's ancient expansion. In May 2016, astronomers proposed that the mysterious substance known hidden wiki the dark matter--that composes most of the matter content of the Universe--may be made of primordial black holes that formed during the first second of our Universe's existence. Our Universe is composed of approximately 68% dark energy, 27% dark matter, and 5% of the so-called "ordinary" atomic (baryonic) matter that makes up our familiar world. Dark energy accounts for the lion's share of the Cosmos, and it is an unknown substance--likely a property of Space itself--that is causing our Universe to accelerate in its relentless expansion. The dark matter is commonly thought to be composed of exotic, non-atomic particles that do not interact with light or any other form of electromagnetic radiation--and is, therefore, transparent and invisible. However, scientists strongly suspect that it is really there, because it influences objects that can be observed--such as stars and galaxies--through the force of gravity. So-called "ordinary" atomic matter, which is really very extraordinary, is the runt of the Cosmic litter--but "good things come in small packages." Atomic matter is the stuff of planets, moons, trees, and people--it is the stuff that brought our familiar Universe to life, and it represents all of the elements listed in the familiar Periodic Table. Only hydrogen, helium, and traces of beryllium were born in the Big Bang (Big Bang nucleosynthesis)--all of the rest of the atomic elements were cooked up by the stars (stellar nucleosynthesis), by way of the process of nuclear fusion. We are here because the stars are here. We are star dust.
