Curious Speculations on Black Holes
Posted on January 16th, 2010 No commentsTwo ideas about dark holes lead to a whole bunch of interesting derivative ideas.
1. In dark holes, time appears to come to a stop inside, when viewed from an outside observer.
2. Another interesting aspect of dark holes is that the Schwarzchild radius is directly proportional to the mass. This has peculiar ramifications when examined from the perspective of a large volume at a constant density. As the radius of a spherical volume increases with a given density, the mass increases as a cube-function, while the radius increases linearly. This means, no matter how tenuous a gaseous medium you have, if it’s large enough, then you will be inside a dark hole; a closed space-time manifold from which you may not escape.
Quite a wild ride of speculations can be derived from these two concepts. Even Mr. Toad would likely get carsick.
First, is it possible for a singularity to form in the center of a dark hole, from the perspective of the outside universe? As the mass collapses to initially create the dark hole, time “stops” and the collapse never quite finishes. If you were inside the Schwarzchild radius, this would be a different matter, as you accelerate toward the center of the dark hole to ultimately become part of a singularity, although this might take a billions years of your referential time frame. The book “Frozen Star” by George Greenstein mentions the lack of a complete collapse into a singularity, and the stasis of the time-domain when the event horizon first forms (or at least that’s what I seem to remember from it – sorry, George).
The funny thing about this is that if time is frozen in this shell, and a thousand years of outside time pass, and then another dark hole forms somewhere else, as far as the “inside observer” is concerned, both his dark hole and the other dark hole were created at the same instant (even though, of course, he couldn’t observe that event). So from the perspective of the first person in the first dark hole ever, all the stars in the universe that would ever collapse into dark holes all through outside-time occur simultaneously relative to his inside-time. If our universe is expanding, we reach a cold death with widely distributed dark holes as our only legacy, each one eternally frozen in time from our outside perspective from their final collapse into singularities.
If, however, the universe is collapsing, then all these frozen-dark holes will eventually run into each other (they will be the only thing left in the universe, having absorbed everything else) and the only time domain will be that of the continuity inside the dark hole. I’m guessing that this will be a sort of Big-Bang, a new universe headed towards its own singularity. But inside this new Big-Bang dark-hole, in its time frame, this could take aeons.
In this new universe the mass density will be so high that it will spontaneously disintegrate into millions of new dark holes (taking millions of years to do so in its own time frame, eventually repeating the cycle of our own collapsing universe, resulting in a new super-dark hole which also will never reach its own singularity.
But lets look at our current universe. It’s big, and it’s a tenuous density. Per paragraph 2, though, we find that no matter how diaphanous the density, if its large enough, it will have a Schwarzchild radius and be a closed 4-D manifold (or however many dimensions one wishes upon us). We live inside a dark hole, headed for our own singularity which may never occur because of the dark-hole cycle described above. Is it possible?Consider the standard concept of a Big-Bang theory. There is a momentary instant wherein everything explodes outward, with incredible energy and density. If we assume that any of the physics theory of dark holes have any bearing on the first few seconds of creation, then the first thing that will happen is for the universe to create billions of dark holes. If we consider the example of all the universe’s dark holes suddenly appearing together, popping into existence (from the “insider’s viewpoint”) in one place as the universe collapses (keeping in mind that for the insider, this happens instantaneously after the dark hole he occupies is created), then it appears that the “explosion” of the universe at creation is nothing more than the sudden appearance of all the universe’s dark holes in one place in one moment of time. It may seem like a Big Bang, when it is in fact just a sudden merging of all the mass in the universe in one place.
We can consider higher dimensions in this scenario; in the standard Big-Bang the first thing to happen is that higher dimensions will collapse into lower dimensional manifolds, creating some sort of new geometry, then energy levels will drop further, creating the next lower dimensional level of geometry, say from a tenth dimension to a ninth dimension, each dimension curling down into a loop, its own Schwarzchild radium heading toward a dimensional singularity but never reaching it. This process of cooling continues until we’re down to our own 4 dimensions, oblivious to the process as it continues. The curling of dimensions into themselves, creating subatomic particles, is the first level of dark-hole creation, with different flavors of dark holes being created depending on which dimension in the manifold is collapsing. One might think that a lack of directionality would prevent any distinction of one dimension from another, but if there’s any directionality for the universe’s expansion, then this might determine and define the zoo of subatomic particles that now exist.
During the collapse of the universe, the highest energy level available might determine the highest unfolded dimension; there could be a simple equation that forces a new dimension into existence based on the energy level achieved. So the total mass of the universe, and the way it collapses, could determine the highest dimension that’s relevant to us. There could be an infinite number of dimensions available if you had the mass/energy density to achieve them, but to us they’re invisible because they are symmetric in all of our existing dimensions; they cause no differentiation between particle properties. A 12th dimension is irrelevant if it has no distinctive character in our existing framework of differentiated mass.
In numerous texts on dark holes, they state that the time flow in a dark hole is toward the center (singularity). Inside the Radius, “forward” in time is toward the center, and “the past” is toward the Radius. So our own “forward” time in our dark-hole universe could be toward our own singularity, which will never happen due to the ultimate recollection of mass in the ultimate dark hole.
Can dark holes expand? What an excellent question. In our own universe, if we look at a dark hole and add mass to it, the radius gets bigger and the mass gets bigger and it expands, but time is still frozen. But by itself, it doesn’t appear to expand because our time sense says it’s frozen in time. To the internal-time sense, a huge influx of mass is going to occur instantaneously and it will most certainly expand outward. We currently see our own universe expanding; is this due to the addition of mass from other dark-hole universes like our own, falling into it? Or did all the mass that will ever enter already do so when our dark hole universe was first created? Is what we perceive as the expansion of our universe really the compression toward a singularity? Or does our consciousness work backward through the collapse of the dark hole toward a singularity, presenting the illusion of expansion? Is the only thing that makes our universe expand the continued addition of mass into our event horizon? Or can a dark hole actually expand on its own, thus making itself more tenuous until Bang! There’s no more event horizon and we connect to the “outside” universe (thus adding more mass and creating a new horizon). If we acquire more mass and a new horizon, could this be a gradual and continuous process that allows the universe to appear to expand? Can the two processes work together?
So many possibilities!

Scupdate and then some…
Posted on January 16th, 2010 No commentsWell, got my labs and things back from the doctor– and we have a TSH of 0.2, FT4 of 29.0, FT3 of 6.1, and a detectable Tg… cute! Somehow despite all of the good things with my TSH and T4, I still don’t feel great. I’m still extremely tired and just feeling generally hypo. Oh well– hopefully that’ll clear up soon.
Along with the lab results, I also got the recommendation letter to give to the nuclear medicine doctors in HD for my second therapy. The endocrinologist made it clear in his letter that he has high hopes for remission following this upcoming treatment– which would be great! Then just follow ups every 6 months!Otherwise, things are going pretty well– studying for my physics theory exam that has been looming in front of me for the past 4 months, and going to the gym regularly. It’s hard to explain, but I think my body has become addicted to cardio workouts– it’s almost as if when I don’t go, I feel bad. I’ve been doing Tae Bo courses, as well as some stomach and back specific mini-courses… I also tried Kettelbells today– which, for those of you who have recently had thyroid surgery, really seem to strengthen the right neck muscles without making you feel like your head will fall off– I would highly recommend it! I will also try the sauna tomorrow, after my Tae Bo course. I can’t wait! I haven’t been in a sauna for about 5 months– and recently I’ve been afraid because of my heart. But I figure that if I was able to keep up in the Tae Bo courses for at least 2 in a row, my heart will withstand the heat- and hell, if I get a round of palpitations, I can always just leave and take a cold shower.
I have some pictures I took of my scar over the past few days:

Homeschool Physics experiment you can do with your kids
Posted on January 16th, 2010 No commentsWhy things bounce, fly, zoom, and splat are described by the laws of physics theory Motion most children learn in their physics theory class in high school. But there is no need to wait until the child hits puberty to have fun with physics theory – you can start right now. Children all over the world use the law of gravitation everyday to put the zing in their games, from basketball games to skateboarding. Let's see how they do it.
Let's look at the first law of motion. When you insert aball on the floor and stays put. A textbook science will tell you this: an object at rest tends to stay at rest unless acted upon by an outside force. The foot is the external force. Kick it!
What about when the ball hits something? Checking back in with the science textbook: An object in motion tends to stay in motion unless acted as an external force. After kicking the ball (outside force), flying through the air until it knows something.
But thereare two forces acting on the ball that you can not see. One is the force of air resistance. The ball strikes the air molecules when you fly through the air, which slows it down. The other force is gravity. Gravity is inherent in everything that has mass (including you), but you need something the size of a planet before we can begin to see the effect it has on other objects. If you launch the ball in space (away from any gravitational pull near as darks holes or galaxies), wewould continue in a straight line forever. There are no molecules to its collision with and without gravitational effects to pull it off course.
There is one more idea that you need to understand – the acceleration. A ball at rest has a position that is plotted on a map (latitude, longitude and altitude), but not the speed or acceleration. Not move. When you decide to mix things and kicking the ball, that when it gets interesting. The second your foot touches the ball, things startchange. Speed is the change of position. If you kick the ball ten meters, and takes five seconds to go the distance, the average speed of the ball is 2 meters per second (about 1.4 MPH).
The hardest part of this scenario has to do with the acceleration, which is the change of speed. When driving on the motorway at a steady 65 MPH, the acceleration is zero. Speed does not change, so you have no acceleration. Your position is constantly evolving, but it is constantspeed. When you get on the highway, the changes in speed from zero to 65 MPH in ten seconds. The acceleration is greater when the foot strikes first gas – when the changes of speed more.
There is an interesting effect that occurs when traveling in a curve. You can feel the effect of a different kind of acceleration, when suddenly the car turn right – you feel a push to the left. If you're going fast enough and take the turn hard enough, you can get slammedagainst the door. So – that pushed you?
I think back to the first law of motion. An object in motion tends to stay in motion unless acted upon by an outside force. This is the most amazing part – the car is the external force. Your body has been the moving object, wishing to stay in motion in a straight line. The machine turns, and your body is still trying to maintain its straight path, but the machine is obtained as. When you slam the door in the car, the car is turning itself into your path,forces you to change direction.
This effect is true when traveling by car or on a roller coaster. And 'the reason for the water remains in the bucket when you swing over your head. Physical movement is everywhere, difficult children learn to walk as well as Olympic skiers to go away.
Let's try these ideas.
Splash Fill bucket half full bucket of water. Grasp the handle and swing over the head in a circle in a vertical direction. TrySpinning Around while holding the handle forward to swing the chest in the horizontal plane. Vary the speed of rotation to find the minimum!
Marble Vortex Curl a piece of paper into a cone, leaving a small hole open at the bottom. Place a marble in the cone and find the speed you need to round the cone to keep the marble in the cone. NOTE: This is an excellent demonstration of satellites. The satellite is the marble and the top of the cone is the earth. Ifmarble is moving too fast, you will fly out of the cone (which is equivalent to the satellite out of orbit and fly in space). If the speed of the marble is too slow, which falls at the bottom of the cone (translation: the fall of satellites in earth). There is a very specific velocity, the satellite must maintain to stay in orbit.
Ping Pong Curve Attach a clear, plastic cup until the end of a long piece so that the bottom of the cup is located along the length of the ankle towards the end (whenthe ankle is lying on the floor, the cup points). Place a ping pong ball into the cup and catch the free end of the stick with his hand. Swing it while it's going through a circle and suddenly STOP. The ball should pop out of the cup in a line tangent to the circle at the point where it stopped. Why not keep the ball in a circle or stay in the cup?
Answer: An object in motion (the ball), wants to stay in motion (a straight line) and is free to do so when he stopped. Initiallygoes in a straight line tangential to your bow, but then gravity takes over and goes down to the ground.
Cork accelerometer Fill a empty bottle of soda to the top with water. Change the cap of a bottle of soda as follows: Attach a string of 8-10 "long clean wine stoppers. Hot glue the free end of the string inside the hood. Put the cork in the bottle and the string and screw on top (try to eliminate air bubbles). The cap should be free to bob around when you hold down thebottle upside down.
To use the accelerometer: Invert the bottle and try to move the cork on. Remember – do you measure the acceleration, which is the change in speed. It moves only when the speed changes.Roller Coaster physics theory This is the best way to learn physics theory. All you need is a handful of marbles, several pieces of ¾ "foam pipe insulation, a pile of duct tape, and a crowd of participants.
To make the roller coasteryou need to pipe insulation foam, which is sold in increments of six feet to the hardware store. You will be cut in half lengthwise, so that each piece is forty feet of track. These are in all formats, so you take your marbles when you select the size. The ¾ "size fits most marbles, but if you're using ball bearings or marbles shooter, try it at the store. (At least you will have smiles and interest from the hardware store salespeople.) Switched on the mostlong track (the hard way) with scissors. Will find it is already sliced one hand, so this makes your job easier. Leave some pieces cut to become "tunnel" for the roller coaster later.
The next step is to join the track together before adding all the features, such as loops and curves. Merge two tracks together in a butt joint and press a piece of masking tape lengthwise along the inside and underside of the track. A third piece of tape should go around theentire circumference of joint. Make these connections as smooth as possible, because the marble high-speed roller coaster will tend to fly off the track at the slightest shock.Roller Coaster Loops Maneuvers Swing around the track in a full circle and enclose the outside of the track chairs, table legs and hard floors with tape to ensure on the spot.
Loops get some 'speed to make through, so you have your partner hold it while you test the first taping. Start withrings smaller increase in size and speed for your input in the circuit. Loops can be used to slow down a marble if speed is a problem.
Camel-Backs Make a hill outside the track in an inverted U-shape. Good for show, especially if you get the height of the hill just so that the marble is a little off track ', then again without missing a beat.
Whirly-Birds Take a course and make it horizontal. Great around poles and posts, but only keep the bank angle fairly steep andMarble speed fast enough so that it does not fly off the track.
Corkscrew Start with a basic cycle, then expand the entry and exit. The further away they get, the funnier it becomes. Corkscrew usually require a higher speed loop the same size.
Jump-off is an important exhibition that requires very strict entry and exit to the track. Use lots of tape and tilted input (end of the runway), slightly decreasing, while the output (start of new trackpiece).
Pretzel The cream of the crop in the maneuvers. Make a very loose knot, resembling a pretzel. Angles and speed are critical, with the placement of a second track rigid grip. If you have problems, make the smallest pretzel and try again. You can bank on every corner of the piece, because the foam is so soft. Use lots of tape and a solid surface (bookcases, chairs, etc.).
Troubleshooting Marbles fly everywhere, so make sure you have a lot of extras! IfThe marble is not following the track, with great attention to the point of departure – where he flies away.
oDoes position change tracks with the weight of marble, making flying off course? " Making the most track tape drive on a surface.
ois marble jump over the wall track? Increase your bank angle (the amount of twisting the track makes its length).
oDoes marble just fallen out of the loop? Increase the speed of marble from a higherposition.
oWhen all else fails and marble, still will not stay on track, do a stretch of tunnel to be taping another piece on top of the main runway. Spiral-wrap the tape along the length of both sides to ensure a whole.

Quantum computers do chemistry
Posted on January 16th, 2010 No commentsQuantum computers do chemistry – physics theory-math – 11 January 2010 – New Scientist
A team of quantum physicists has taken the first steps towards using a quantum computer to predict how a chemical reaction will take place.
Even the most powerful classical computers struggle when trying to calculate how molecules will interact in a chemical reaction. That’s partly because the complexity of such systems doubles with the addition of every atom, as each atom is entangled with all the others.
Such escalating complexity is far easier for a quantum computer to deal with, because quantum computers exhibit similar properties: adding just one extra quantum bit or “qubit” doubles computational power. “There is a natural match between quantum computers and modelling chemistry,” says Andrew White at the University of Queensland in Brisbane, Australia.

Signals and Systems, 2nd Edition by Alan V. Oppenheim, Alan S. Willsky, with S. Hamid
Posted on January 16th, 2010 No comments
The second edition of this well-known and highly regarded text can be used as the basis for a one- or two-semester undergraduate course in signals and linear systems theory and applications. Topics include basic signals and systems concepts, linear time-invariant (LTI) systems, Fourier representations of continuous-time and discrete-time signals, the CT and DT Fourier transforms, and time- and frequency-domain analysis methods. The author emphasizes applications of the theory through numerous examples in filtering, sampling, communications, and feedback.
The parallel development of continuous-time and discrete-time frequency domain methods allows the reader to apply insights and intuition across the two domains. It also facilitates a deeper understanding of the material by bringing into focus the similarities and differences between the two domains. The text also includes introductory chapters on communication systems and control theory. This book assumes that you have a background in calculus as well as exposure to complex numbers and elementary differential equations. Because of its thoroughness and unhurried pace, this text is highly recommended for students and those interested in self-study.

Sky News US may use Guantanamo for Haiti effort ” ‘It’s a resource that’s available if we need to take advantage of it for various reasons,’ General Douglas Fraser, head of Southern Command, told a press conference on Wednesday.”
“Fraser was asked if the Guantanamo base, which also includes the controversial US military prison for terror suspects, could be used to house refugees or even to take in inmates from prisons in Haiti that may have collapsed in Tuesday’s massive earthquake.“
Looking at my atlas and realizing that Port-au-Prince is only ~100 miles from Guantanamo Bay, I was not surprised to find this story. I have also been thinking about the recent alleged discovery of a Previously undiscovered ancient city found on Caribbean sea floor .
