The Last Three Minutes: Conjectures About the Ultimate Fate of the Universe

Description
Ragnarok. Armageddon. Doomsday. Since the dawn of time, man has wondered how the world would end. In The Last Three Minutes, Paul Davies reveals the latest theories. It might end in a whimper, slowly scattering into the infinite void. Then again, it might be yanked back by its own gravity and end in a catastrophic "Big Crunch." There are other, more frightening possibilities. We may be seconds away from doom at this very moment. Written in clear language that makes the cutting-edge science show more of quarks, neutrinos, wormholes, and metaverses accessible to the layman, The Last Three Minutes treats readers to a wide range of conjectures about the ultimate fate of the universe. Along the way, it takes the occasional divergent path to discuss some slightly less cataclysmic topics such as galactic colonization, what would happen if the Earth were struck by the comet Swift-Tuttle (a distinct possibility), the effects of falling in a black hole, and how to create a "baby universe." Wonderfully morbid to the core, this is one of the most original science books to come along in years. show lessTags

This book was quite interesting. The cover pretty much sums it up. Ever since people figured out that the Universe is expanding, it immediately followed that it must have had a beginning. Before this, many scientists merely assumed that the Universe just lasted for an infinite amount of time. Given that the Universe had a beginning it must also end sooner or later. The matter of how it will end is up for speculation and there are several possible ways. None of these ways are particularly pleasant, but I can take solace in the fact that I will be long dead by the time all of this comes to pass. We're not talking about decades, in this case, we are not even talking about millennia. Billions of years must pass before any of this even comes show more close to happening. By that time the sun will run out of Hydrogen Fuel to use and will start to use Helium to fuel itself. At that point, the Sun will expand until it engulfs the orbit of Venus and the oceans will boil away.
Of course, we could also be destroyed by a giant asteroid or some other space object. This too would take a while, but we are protected in the sense that space is massive, and the Earth is relatively small in it. So then there are other ways for our Galaxy to Bite the Bullet, so to speak. It could collide into another Galaxy, There could be a Giant Black Hole that sucks us into itself, but none of these events are very likely.
The ultimate end of the Universe depends on two things. The first is the amount of mass in the Universe, and the second is the rate of expansion of the Universe. Now, these are generally called the Big Crunch or the Big Freeze. This is generally what I call them. Either the Universe collapses back on itself, or it expands so much that new stars cannot be born. All of the stars will eventually become either Black Holes or Black Dwarfs, massive chunks of matter that are mere husks of what they were.
None of this is really important, though, since I will be long dead by the time all of this happens, unless they find some way for me to become a Star Child a la 2001: A Space Odyssey. show less

Los últimos tres minutos, obra del fÃsico y escritor Paul Davies, es un libro maravilloso y divertido que recoge las más recientes ideas cientÃficas sobre el destino último del universo, transportando al lector a vivir las sensaciones que experimentará cuando llegue el final. El lector asiste al último dÃa de luz solar y a la llegada de la noche perpetua. Experimenta el inicio del cataclismo estelar, una vez que se haya agotado definitivamente la energÃa de las estrellas activas, y viaja por los eones de tiempo en los que los agujeros negros son la última fuente de energÃa importante, devorando los restos dispersos de las galaxias apagadas. Y luego, quizá, podrá vivir el gran crujido, esos últimos tres minutos en los que show more la temperatura del cosmos se hace tan grande que incluso deben desintegrarse los núcleos atómicos, en que regiones cada vez mayores de espacio se comprimen en volúmenes cada vez menores, cuando «la obra del gran pum y de generaciones de estrellas se deshace en menos tiempo del que se tarda en leer esta frase». ¿Será éste el escenario en el que la vida cósmica represente su escena final? ¿O está destinado el universo a acabar de forma muy distinta y en un futuro mucho menos lejano, avasallado por una catástrofe cósmica súbita e inesperada? ¿Se acabará de verdad el universo? Y si dura eternamente, ¿hallará la humanidad, o sus descendientes, sean robots o seres de carne y hueso, el modo de sobrevivir a esa eterna noche? Los últimos tres minutos es uno de los libros de ciencia más originales que han aparecido en los últimos años, lectura fascinante de un cientÃfico plenamente acreditado. show less
