81. Time Travel Is It Possible
    Interview with Steven Gibbs, documented incident of possible timeslippage, scientific premises of possibility, warping time, cosmic strings, paradoxes, wormholes, black holes, movie and book reviews.  
    http://www.strangemag.com/timetravel.html
    
    Extractions: Inspired by the Time Travel theme of Strange Magazine 14 (Fall, 1994) our Strange Web Site Time Travel pages include some of the high points of that issue, as well as some classic time-bending High Strangeness from our Louisiana correspondent Ken Meaux. Ken's haunting piece has been reprinted, retold, and cited many times since it debuted in Strange Magazine 2 (Spring, 1989). Never-before-published material includes Douglas Chapman's quick tour of some time travel movies. Sherrill Roberts discusses the possibility that modern physics may provide some mechanisms for moving though time. Time Travel book reviews and a suggested reading list round out the Time Travel Pages.

"A luminous star, of the same density as the Earth, and whose diameter should be two hundred and fifty times larger than that of the Sun, would not, in consequence of its attraction, allow any of its rays to arrive at us; it is therefore possible that the largest luminous bodies in the universe may, through this cause, be invisible." Pierre Laplace, The System of the World , Book 5, Chapter VI (1798). Clouds of Hydrogen begin condensing into more dense clusters due to gravitation. Eventually the density gets high enough that the Hydrogen begins fusing into Helium. This fusion releases energy, mostly in the form of electromagnetic radiation. Our sun is currently in this phase. Note that the gravitational attraction of the matter of the star is trying to make it smaller; this is balanced by the radiation pressure that is trying to push the matter outward making the star bigger.

Or, picture an infinite continuum of parallel universes, each inhabited by slightly different parallel twins of yourself.Visualize a place in which all the laws of physics, that combine to make our universe the place that it is, vanish into inscrutable infinities. Welcome to the world of one nature's most bizarre phenomena: the black hole. Figure 1: The Rubber Sheet Analogy of Gravity Shortly after the publication of the General Theory, physicists began to explore this strange new world. The theory is so very complex, and the mathematics so difficult, that even today, scientists have barely scratched the surface of this powerful theory. One of the very earliest solutions to the equations was developed by the German physicist, Karl Schwartzschild, in 1916. The Schwartzschild Black Hole Figure 2: Diagram of Schwarzchild Black Hole Assuming that we could find a volunteer to journey into a Schwarzchild black hole, what would he experience? Passing through the photon-sphere, he would be flooded with intense light. As our volunteer left the brightness, he would find himself in utter darkness. He would feel his velocity increase to unbelievable levels. Approaching the event horizon, our astronaut would be subjected to tidal forces of astronomical proportions. His feet would seem to weight uncounted trillions of tons more than his head. In a blinding instant, our poor volunteer would be disintegrated into atoms. He would then crash into the singularity, where his mortal remains would be summarily smashed out of existence (4).

    Extractions: BLACK HOLE : A cosmic body of extremely intense gravity from which nothing, not even light can escape. It is formed by the death of a massive star and only the most massive stars become black holes at the end of their lives. Even though a black hole is difficult to observe on account of both its small size and the fact it emits no light; it can still be seen however, by the effects of its enormous gravitational fields on nearby matter.

    Extractions: A massive astrophysical object that is theorized to be created from the collapse of a neutron star . The gravitational forces are so strong in a black hole that they overcome neutron degeneracy pressure and, roughly speaking, collapse to a point (known as a singularity). Even light cannot escape the gravitational pull of a black hole within the black hole's so-called Schwarzschild radius Uncharged, zero angular momentum black holes are called Schwarzschild black holes . Uncharged nonzero angular momentum black holes are called Kerr black holes . Nonspinning charged black holes are called . Charged, spinning black holes are called Kerr-Newman black holes .

Penrose proved the singularity theorem , which says that a singularity must reside inside every imploding star, and therefore every black hole. In 1969, Lifschitz, Khalatnikov, and Belinsky showed that tidal gravity oscillates chaotically near the singularity. They also found the particular type of singularity, now known as a BKL singularity . Black holes can pulsate, as was recognized by Press (1971). Over the next decade or so, the pulsations were shown to always be stable using perturbation methods. In 1973, S. Hawking showed that black holes radiate as if they have a

SPACE.com Black holes will eat just about anything, and now astronomers have confirmed that stars are on their menus. Observations from three space-based X-ray telescopes over about a decade provide the first solid evidence of a star being torn apart and partly swallowed by a black hole. Astronomers already have plenty of evidence for black holes consuming gas that swirls inward and is superheated, generating radiation in many wavelengths from radio to visible light and X-rays. They have long assumed that whole stars could be torn apart by the gravitational tug of a black hole, but proof has been elusive.

    http://www.kidsastronomy.com/black_hole.htm
    
    Extractions: When a large star runs out of fuel it can no longer support its heavy weight. The pressure from the star's massive layers of hydrogen press down forcing the star to get smaller and smaller and smaller. Eventually the star will get even smaller than an atom. Imagine that for a moment an entire star squashed up into less space than a tiny atom. How can something get smaller, but retain the same amount of mass, or stuff? It is really quite simple. If you take a sponge the size of a soda can you can easily squish it in your hands until it is completely covered. But here is the interesting part. If you make something smaller by squishing it, it's gravity becomes much stronger. Imagine then, if you squish a star into the size of an atom how powerful it's gravity would become.

    Extractions: Breaking Time's Arrow Time is a part of everything we do, but not easy to comprehend. Nearly everybody has seen a time travel movie or two in his or her life. Almost all of the science-fiction movies are at least a little time-travel based. The last two science-fiction movies that I saw, Sphere and Lost in Space , both had time travel involved with it. We are familiar with three-dimensional space travel. Moving up, down, left, right, forward and backward are easy for us to do or to visualize. Time on the other hand is different. Movement in time is limited to forward. It is asymmetrical and one dimensional. This is called time's arrow. It also is applied to memories. We can't remember what we "did" tomorrow. Cause always precedes effect. (Einre) I propose that time travel is possible. Time travel has many different theories, problems, and paradoxes. There are many theories on time travel. Most of the theories at least partially use Einstein's work. Einstein's theory of relativity states that at speeds close to the speed of light, color, size, time, shape, mass and other variables change slightly. The constant c represents the speed of light (approximately three hundred million meters per second or one hundred eighty six thousand miles per second). (Lawrence 34-35) The Lorentz factor Sqrt(1-(v/c) )is multiplied or divided to all formulas where any of the above variables are concerned, i.e.,d

    Extractions: Escape velocity is how fast one body has to go to escape from the gravity of another body. To escape from the Earth, you'd have to go a bit more than 25,000 miles an hour. To escape from a black hole, you'd have to go faster than the speed of light, which is about 186,000 miles a SECOND! That's about 669,600,000 miles an hour.

    Extractions: Of Black Holes and Decentralized Law-Making in Cyberspace David G. Post There is, within the (rapidly-growing) community of people who spend their time thinking about law and policy in cyberspace, a rather interesting debate taking place. Though it is not always characterized in these terms, it reflects a conflict between competing visions of "order" and "disorder" in social systems. This is by no means a "new" debate, but it takes on a new shape in the rather special conditions of cyberspace or so, at least, I hope to suggest in what follows. The Incident . Last January, Professor Tom Field of the Franklin Pierce Law Center (FPLC), posted the following message to the Cyberprof listserve: "To all: Assuming that this message isn't screened out by the [the server at the University of Texas that hosts the Cyberprof discussion group], you might be interested in a 'small' problem FPLC faces.

     Extractions: Solar System - The Sun's hot outer atmosphere produces X-rays, but because it is so close (a mere 93 million miles!), it is too bright for Chandra's sensitive eyes. Chandra can observe other objects in our solar system such as comets and Jupiter. Stars - The hot outer atmospheres, or coronas, of normal stars such as our sun produce X-rays. X-ray observations are useful for understanding how the flaring activity of stars can change as stars evolve, and how the evolution of stars is changed if they are in a close binary system. White Dwarf Stars - White dwarf stars are dense, burnt-out remnants of stars like the sun. They are formed when the star contracts after using up its nuclear fuel. When matter from a nearby star falls onto a white dwarf star, X-rays are produced. - When a star blows apart in a supernova, the explosion creates a remnant of multi-million degree gas that shines brightly in X-rays for thousands of years. X-ray observations can reveal the dynamics of the explosion and heavy elements present in the remnant.
