Accretion Disk
In a binary system containing a star and a compact object (white dwarf, neutron star, or black hole) gas may flow from the star to the compact object. According to the theoretical model, the gas will spiral in and fall to the surface of the compact object creating a flow of matter in the shape of a disk. It is generally believed that this model explains many features of X-ray pulsars Apparent Horizon
When matter falls inward to form a black hole it is not always easy to see where the event horizon might be. It might appear at one time that a light ray is capable of escaping but infalling matter might eventually prevent it from doing so. The apparent horizon is a surface on which outgoing light rays are just trapped, and cannot expand outward. It is a stronger condition than the event horizon, and the apparent horizon always lies inside the event horizon, or coincides with it. This situation is analgous to a man running through a corridor filled with doors. He is trying to run outward, but the doors are closing in sequence from the outside in. How many doors will he be able to pass through before he is blocked by a closed door? The door that is closest to him that is currently closed is analgous to the apparent horizon. The door that he will actually reach before he cannot travel further is analogous to the event horizon. Arc Second
The size of a celestial object expressed in terms of the angle that it covers (or "subtends") when viewed from Earth. For example, the moon subtends an angle of 1/2 a degree. One degree of arc is defined as equivalent to 60 minutes of arc (or "arc minutes"). Arc minutes are further divided into arc seconds, such that there 60 x 60 or 3600 arc seconds per degree. So the moon's apparent size can also be expressed as 1/2 degree x 3600 = 1800 arc seconds. If the the distance to an object is also known, then its angular size can be used to calculate its diameter in miles or kilometers.

You can begin by reading a Clicking on any of the underlined key concepts will then take you to the corresponding point in a more detailed In the long course outline, clicking on any underlined key concept will take you to a still more detailed exposition of that concept. Alternatively, you can begin to read some of the adventures of However, unless you are already familiar with general relativity, to understand these adventures you will need to look at the other material from time to time. All this material originated on sci.physics. Much of it is written by Oz and me, but there are also substantial contributions by Ted Bunn, Ed Green, Keith Ramsay, Bruce Scott, Bronis Vidugiris, and Michael Weiss. General relativity is usually written with lots of superscripts and subscripts. Mitchell Charity has kindly improved these web pages so that they look nice. However, not all web browsers can handle this.

    34. Alignment Theory: New Quantum Relativity Theory Of Everything
    Preliminary look at a new approach to relativity, Cosmology and the Quantum nature of the universe.
    Quantum Relativity "Theory of Everything" Alignment Theory Abstract: (Fuller explanation below) Alignment Theory is the mechanism of zero point energy, quantum mechanics, relativity, mass and gravity, cosmology, cosmic inflation, dark energy and the cosmological constant, the nature and speed of light and quantum entanglement, quantum chaos and the lumpiness of the universe. This mechanism unifies relativity and quantum mechanics. The following is a preliminary look at a new, very simple approach to Relativity, Cosmology and the Quantum nature of the universe that explains the proposed mechanism. (This approach is based on a mixture of existing mainstream ideas and some new ones, put together in a new way.
    Relativity and Quantum theory describe the effects, Alignment theory is the actual mechanism.)
    There are three main elements that underlie this approach: 1. Gravity and Mass are the outcome of a two-polarity "Alignment" / "Anti-alignment" energy fluctuation Field. (Momentary alignments of quantum foam fluctuations, explained below.)

    Alternate viewpoint on the Double Slit Experiment which is the experiment that started the moderen QM thought.
    List of selected Usenet Articles by bhanwara
    Here is a list of some usenet articles on Physics (specifically QM SR GR and light ) by Mukesh Prasad (aka , and ) collected here so these discussions are not lost as they roll off the news-server archives. All articles here require open-minded, non-authoritarian thinking.
  • A mechanism is clarified whereby light can propagate in vacuum without requiring mystical properties. Quantum Mechanics interpretations are shown to be incorrect. The actual interpretation involves the fields generated by the electron sources. QM is still a valid line of research, but it is a lot less mystical and therefore potentially more useful than previously assumed. Special Relativity and constancy of light are demonstrated to be incorrect. Despite its mathematical complexity, General Relativity is shown to be trivial and useless in terms of its actual meaning, and slightly incorrect. Some of its incorrectness arises from the fact that it incorporates constancy and Special Relativity. It is also incorrect because of its attempt to use a symmetrical albeit elegant model for an underlying asymmetrical reality (which fact makes the elegance of the model or lack thereof, totally irrelevant. Appropriateness of the model is more important in mathematical models of physical reality, than elegance.)

    37. Chomsky UD
    Review by US political dissident Noam Chomsky of the United States' own appalling record on human rights not in the distant past, but in the last 50 years and continuing right up to this day.
    The United States and the "Challenge of Relativity" By Noam Chomsky This essay will appear in a collection assembled by Tony Evans, dealing with the 50th anniversary of the Universal Declaration of the Rights of Man. The adoption of the Universal Declaration of Human Rights on December 10, 1948 constituted a step forward in the slow progress towards protection of human rights. The overarching principle of the UD is universality. Its provisions have equal standing. There are no moral grounds for self-serving "relativism," which selects for convenience; still less for the particularly ugly form of relativism that converts the UD into a weapon to wield selectively against designated enemies. The 50th anniversary of the UD provides a welcome occasion for reflection on such matters, and for steps to advance the principles that have been endorsed, at least rhetorically, by the nations of the world. The chasm that separates words from actions requires no comment; the annual reports of the major human rights organizations provide more than ample testimony. And there is no shortage of impressive rhetoric. One would have to search far to find a place where leadership and intellectuals do not issue ringing endorsements of the principles and bitter condemnation of those who violate them notably excluding themselves and their associates and clients.

    Special Relativity David Waite's Special Relativity Lecture Tape (2 hours) This Unit focuses on special relativity only. Special relativity is a special case of a more general physics. We use only Cartesian coordinate systems. In special relativity we do not consider gravitation, and it is also not a quantum theory. Thus many of the implications of special relativity that are often quoted as if they were general laws do not hold true in more general physics scenarios. Once special relativity is understood, one may move on to a more general case of physics known as general relativity For those that are ready for this step we have created a section on general relativity - Modern Relativity Special Relativity Preface Unit I Special Relativity Chapter 1 SR Made Simple 1.1 - Lorentz Coordinate Transformation 1.2 - Relative Space and Time 1.3 - Paradoxes ... 3.3 - Rotations, Rockets, and Frequency Shifts

    Some examples of the phenomena of general relativity are simulated. This provides a graphical sight on the main general relativity concepts. The simulations include solutions in 3D (XY +time) and 4D (XYZ+time) spaces.
    ABSTRACT Some examples of the phenomena of general relativity are simulated. This provides a graphical and quite illustrative sight on the main general relativity concepts. The simulations include solutions in 3D (XY +time) and 4D (XYZ+time) spaces. The solutions are more general than those which can be obtained analytically. For example, the approach to the black hole is simulated not only as a radial particle movement, but as an arbitrary trajectory in the 3D space. The distortion of images of far objects seen through a neighborhood of a black hole is simulated using photon trajectories in 4D space. Also the entrance of an arbitrary trajectory into the horizon of the black hole is simulated both with the coordinate time (seen by the static observer) and with the proper time (clock) of the moving body. Time distortion at the neighborhood of the black hole is shown as a 3D “space-distortion” plot. Interesting simulation experiments are also shown for the rotating black hole.
