Gravity is a continuum.
If there is a non-infinitesimal quantizing of the curved space-time interval then this shortest distance of events would seem to eliminate anything happening on any smaller scale. NOTHING COULD HAPPEN THERE. I define the infinitesimal as being a nonzero - the smallest of all quantities. As opposed to the abscence of any quantity - or Zero. MITCH RAEMSCH Gravity seems to have a secret power - it could move a potentially infinite mass. What kind of force can do this? THE STRENGTH OF GRAVITY IS LIMITED IN ACCELERATION - TO LIGHT SPEED BY EINSTEIN'S EQUIVALENCE PRINCIPLE. Curved space-time is absolute. Einstein knew there was something wrong with black holes. He knew that the time slowdown is absolute. The end of General Relativity is not a singularity but is instead the event horizon. If you claim that time stops there you are claiming what about the inside? You cannot have it both ways. To stop time is to end space - unified space-time cannot be split. It is the same for a naked singularity or a Big Bang without gravity. You cannot divorce any force from the whole. Otherwise what you have cannot be said to be unified. And everything is unified from the very begining and forever. Unification is time invariant. When the first equations for black holes were solved they though they saw matter dropping out of the universe. How true that would be. By ending space-time at a singularity you could no longer have anything. No mass or gravity End time - End space - then you End Mass as well and end mass/energy you end gravity. Obviously we do not see galaxies unraveling at their centers so it is safe to say something else must happen. I believe the solution is that matter converts to energy at the apex of gravity's(limited)strength. That is that light comes out when gravitational strength reaches a light speed acceleration equivalent. Seems to fit the bill of what they say they see happening where black holes ought to be. There is a gravitational conversion of matter into energy(light) recycling the mass as something even greater than a supernova. -- Light Falls Everywhere Its At -- -- It never stops and gravity is ubiquitous -- -- The nature of light is in its name -- -- Its C squared lighter than matter -- I believe time has a speed a light speed to be exact. The evidence of this is that you can catch up to it. You catch up and it slows down. This explains a mechanism behind Special Relativity. You catch up to time. I believe that times motion is what carries light around. If you want to see how time moves look at a light bubble with light going not only outward but also in ever direction possible. That's time. Mass bends the motion of time. Light falls because it is being carried by a time whose motion is curving(making curved space). The force that is expanding the universe is anti-gravity. It is the opposite of gravity compressing space-time. Compressing space-time slows light. Slowing time slows light. I claim that the opposite can happen - that light accelerates. Light accelerates where time speeds up or where anti-gravity expands space-time. Its a cosmological twist on special relativity. Where mass slows time there is a force(motion)of gravity proportional to the time slowdown. THIS IS AN INVISIBLE DIMENSION OF MOTION. WE CANNOT SEE SPACE MOVE. We only see it move matter or when it is resisted to create weight. My gravity is dual. It is the cause of General Relativity. A moving time bending around mass makes curved space-time motion. This motion is a limited thing and is equivalent to accelerating matter. The weight experienced in gravity is equivalent to the weight experienced while accelerating - both in quantity and in quality. This sums up the Einstein's equivalence principle. The inconsistancy of GR with SR in the case of black holes must be addressed. Matter falls at light speed at the event horizon. You cannot get around this. Special Relativity and and General Relativity must combine to eliminate light speed freefall. They combine when the strength of gravity is understood as an acceleration of which is limited. The strength of gravity is limited. The motion of gravity is limited. Freefall is special relativistic. When you add the increasing motions while falling the all add up to something less(than lightspeed) by relativistic additions of velocity. |

Hi Mitchell ,
The horizon of frozen stars , You ask , " If you claim that time stops there you are claiming what about the inside ? You cannot have it both ways . " Similar to special relativity , general relativity ( GR ) requires two " free fall " frames of reference , one that is local , an another that is distant . Now , for us humans , the horizon of a frozen star is always the distant frame . GR accurately predicts what we will _ Observe _ when we look at that distant frame . ( Physics is about such observations ) You'd see no heat , no radiation ... It'd look frozen ... Without any " Ticking " . However , " Relativity " , says : The laws of physics , including the speed of light , are the same for all local frames . ( Be they free-fall or inertial ) But if you could somehow be at that horizon , I assume that it would be nearly infinitely hot . |

om... Curved space-time is absolute. Einstein knew there was something wrong with black holes. He knew that the time slowdown is absolute. The end of General Relativity is not a singularity but is instead the event horizon. If you claim that time stops there you are claiming what about the inside? You cannot have it both ways. To stop time is to end space - unified space-time cannot be split. The slowing down of time around a black hole is not absolute. Think about it -- how could it be? What does it mean for time to slow down? Less time per unit time? What time "slows down" compared to is an artificial coordinate time. This coordinate time is just a number humans use to pinpoint an event in space-time, much like latitude and longitude are used to pinpoint a location on earth. Longitude lines get closer together near the north pole. The difference in longitude between the ends of a meterstick pointed east-west is much larger near the north pole, but that doesn't mean that our meterstick has expanded. The situation with time near a black hole is analogous. One way of understanding coordinate systems in general relativity is by an analogy with maps. We could make a map of the earth on which a location's height above the origin was proportional to its latitude, and its distance to the right of the origin was proportional to its longitude. On such a map, objects near the north pole would be highly distorted. They would be stretched in the east-west direction. Because the earth is curved, all flat maps of it will be distorted. Since you can make any coordinate system into a map, all coordinate systems will at some place inaccurately represent distances. That, of course, doesn't mean that we can't calculate the true distances, just that we will need a correction factor, comparing differences in coordinate systems to actual distances. For small distances, one can, in general, use this formula: distance = sqrt[ g_xx * (dx)^2 + 2 * g_xy * (dx)(dy) + g_yy * (dy)^2 ] where dx = difference in x-coordinate dy = difference in y-coordinate g_xx, g_xy, and g_yy are a set of numbers called the metric tensor. For the latitude-longitude coordinate system, the formula is: distance = sqrt[ r^2*cos^2(y)*(dx)^2 + 2*0*(dx)(dy) + r^2*(dy)^2 ] where x = longitude in radians y = latitude in radians The situation is analogous in general relativity. Because space-time is curved, there will always be a discrepancy between coordinate time and position differences and real times and distances. This does not mean that time or space has grown or shrunk, or has sped up or slowed down, just that we need a correction formula if we want to get real distances and times from coordinate differences. The Schwartzschild coordinate system was the first coordinate system used to describe black holes, and it is still the most commonly used one. Here is the formula to get small time intervals near a black hole from differences in Schwartzchild coordinates between events: time = sqrt[ (1-2M/r)(dt)^2 - (dr)^2/(1-2M/r) - r^2*cos^2(y)*(dx)^2 - r^2*(dy)^2 ] where M is the mass of the black hole, t, r, x, and y are our coordinates, and units are chosen so that c=1 and G=1. Let's imagine someone hovering outside a black hole, staying at the same r, x, and y. Only t -- the coordinate time is changing. How many real seconds go by for that person in one second of coordinate time? Since dr=0, dx=0, and dy=0, time = sqrt[ (1-2M/r)(dt)^2 - (0)^2/(1-2M/r) - r^2*cos^2(y)*(0)^2 - r^2*(0)^2 ] = sqrt[ (1-2M/r)(dt)^2 - 0 - 0 - 0 ] = sqrt[ (1-2M/r)(dt)^2 ] = sqrt(1-2M/r)*(dt) So, in one second of coordinate time, sqrt(1-2M/r) seconds of real time pass. As we get closer to the black hole, r decreases, and less real time passes per coordinate time. It looks like time is slowing down, but that just means our coordinate system is distorted. At the event horizon, r=2M, and something strange happens when we plug that into the formula: time = sqrt(1-2M/r)*(dt) = sqrt(1-2M/2M)*(dt) = sqrt(1-1)*(dt) = sqrt(0)*(dt) = 0 So, it looks like time has stopped! It looks like someone who goes to the event horizon, within a finite amount of his own real time, can reach the infinitely distant future. Is this the end of time? Not necessarily. Let's remember the analogy with the map again. On our latitude-longitude map, there was an immense distortion around the north pole. Someone looking at such a map might come to all sorts of ridiculous conclusions about the north pole. He might conclude, for example, that it was a line. That's not his fault, though, it's the coordinate system that's a problem in that area. If he just looked at a different map, like a map centered on the north pole, he wouldn't come to such erroneous conclusions. And it turns out that the problem at the event horizon was a coordinate problem problem as well. Use the right coordinate system, and time doesn't stop, and you can get to the singularity. ----== Posted via Newsfeed.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeed.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= 19 East/West-Coast Specialized Servers - Total Privacy via Encryption =--- |

I counted at least 20 wrong or fallacious statements in the above. Can anyone do better? If you are claiming everything I have written is false then I guess I have done my job right. Mitch Raemsch I left something out. Another error in GR gravity. At the event horizon there would be an infinite Einstein shift. An infinite redshift? There are null energyless photons? What nonsense. |

Think about it. Then you are saying there is energyless light? A dead photon? Poppycock. The theory clearly breaks down at the event horizon and must be replaced by a limited strength theory. Get out of your imagination. People who work with imaginary physics and who will not recognize it are the problem.
