Exogravitation - John T Cullen's innovative theory for a new cosmology now has a name, based on his view that Dark Energy is nothing more than old fashioned gravity, but with a stunning twist. This is a challenging nonfiction work, a Gedankenexperiment (thought experiment) designed to tickle the imagination of cosmology professors and serious students.
Exograv theory explains how it's possible that the universe is not only expanding, but doing so ever faster. Where is that energy coming from? The best that cosmologists (scientists who study the nature of the cosmos) have been able to devise is what engineers call a 'black box' approach. We know the inputs, we know the outputs, but we have no idea what goes on during the transformation or throughput. Dark energy cannot be created out of nothing - such an idea would violate the laws of thermodynamics. If there is Dark Energy in the system, where has it been hiding all these eons?
John T. Cullen offers a radically new answer: exogravitation. We don't need to imagine hidden energy and impossible solutions. Instead, think about this: falling objects accelerate naturally and at easily predictable rates. Exogravitation (literally, 'gravitation from beyond') posits that our universe is one of infinitely many in a limitless Motherverse. The ambient gravitation of all those universes is pulling our universe apart in all directions, so our universe is falling (and falling apart) ever faster in all directions...
The universe attenuates, meaning its particles grow ever father apart, until it reaches the Cosmopause. That is a spherical size at which our universe no longer has the gravitational strength to hold itself together. It vanishes like a soap bubble, and its dark gravitational matter (yes, that's the other component: Dark Matter) rejoins all the other fundamental dark matter of beyond... until random Brownian Motion (simple turbulence, as in pond water) starts gathering more and more matter to build the next universe.
This book is filled with history as well as science. Among other things, we learn how the geocentric and heliocentric theories competed as long ago as ancient Greece in the age of Aristotle and Plato. We learn how an established theory is contantly being patched and stretched, until it can no longer compete with a sleek new theory. That's how we arrived at this wild new vision of Exogravitation in the 21st Century.
