...Approximately 14 billion years ago, the universe that stands today was born. There are various explanations for how it was created. Research shows that they are essential scientific questions and it stimulate scientists to debate their research. Many scientists from all over the world and different time periods work to find the reason behind its creation. The different theories on the origin of the universe have a great impact on the way humans view how the universe was created. The most known is the Big Bang theory and smaller theories include the String theory, the Incredible Bulk theory, the Times Arrow theory and the Steady State theory. (Tate) The universe is almost 14 billion years old. There are two common ways scientists use to calculate how old the universe is. The first method involves measuring the speeds and distances of the galaxies. Scientists interpret that the galaxies were closer together before in the past because all of them are slowly moving further from each other every second. Identifying the current speeds and distances of the galaxies, included with the rate at which the universe is accelerating, permits scientists to calculate how long it took...

...Big Bang Theory - The Premise The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment. According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know. After its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this...

...BLACK HOLE A black hole is a theoretical region of space in which the gravitational field is so powerful that nothing, not even electromagnetic radiation (e.g. visible light), can escape its pull after having fallen past its event horizon. The term derives from the fact that the absorption of visible light renders the hole's interior invisible, and indistinguishable from the black space around it. . The idea of an object with gravity strong enough to prevent light from escaping was proposed in 1783 by John Michell, an amateur British astronomer. In 1795, Pierre-Simon Laplace, a French physicist independently came to the same conclusion. Black holes, as currently understood, are described by the general theory of relativity. This theory predicts that when a large enough amount of mass is present in a sufficiently small region of space, all paths through space are warped inwards towards the center of the volume, preventing all matter and radiation within it from escaping. While general relativity describes a black hole as a region of empty space with a point-like singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account. [pic]Name The term black hole to describe this phenomenon dates from the mid-1960s, though its precise origins are unclear. According to Einstein’s general theory of relativity, as mass is added to a degenerate star a sudden collapse will take place and the intense...

...The Mind-Brain Problem JOHN BELOFF Department of psycho log^, George Square, University of Edinburgh, Edinburgh EH8 9JZ, Scotland Abstract-The mind-brain problem, which is still with us, raises the question as to whether the mind is no more than the idle side-effect of our brain processes or whether the mind can, in some degree, influence behavior. Here we rehearse the arguments on both sides plus some desperate recent attempts to eliminate mind altogether. What is the Problem? However contentious, the philosophical problem, as distinct from the physiological problem, can be stated quite simply as follows: What, essentially, is the relationship between events in the brain and those private, subjective, introspectible experiences that together constitute our inner mental life? We need not assume here that consciousness is synonymous with mind-consciousness may well be no more than just one aspect of mind-but, with respect to the problem at issue, it is the existence of consciousness that is critical. Stated thus, the problem admits of only three basic answers: (1) Events in the brain, operating in accordance with the laws of physics, determine completely both our behavior and our subjective experiences. (2) Mental events may be elicited by events in the brain or they may, in turn, elicit brain events and so influence the course of our behavior (I use here the word 'elicit' rather than 'cause' advisedly since the kind of causation here envisaged is so unlike ...

...Dinosaur extinction is still a major mystery of earth history. In this review article, extinctions in the geological record will be briefly mentioned. Many of the imaginative theories for the extinction of the dinosaurs will also be presented. Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of paleontologists. Both theories have their strengths and weaknesses. The unscientific behavior of those involved in the meteorite paradigm change will be briefly explored. Evidence that the dinosaurs died in a cataclysm of global proportions will be presented, such as the huge water-laid dinosaur graveyards found over the earth. Occasional nonspecific bone-beds and the rarity of fossils of very young dinosaurs suggest a catastrophic death and burial. The billions of dinosaur tracks recently discovered provide testimony to unusual, stressful conditions. Nests, eggs, and babies are a challenge to a Flood model, but there are enough unknowns associated with the data that solid conclusions are difficult to draw. The part that impacts and volcanism play in a Flood paradigm will be briefly discussed. The question of whether the K/T boundary and the extinction of the dinosaurs should be considered a synchronous event within the Flood will be considered. Introduction Dinosaurs bring wonder to children and adults alike. That such great beasts once roamed the earth...
