Initial Tests Fail To Find Gravitational Waves

Posted August 21, 2009 9:23 AM

From Slashdot:

Though gravitational waves are predicted to exist by Einstein's Theory of General Relativity, the initial tests run by the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration (LIGO) failed to find anything. It doesn't disprove their existence although it does rule out a subset of string theory. From the article, 'For example, some models predict the existence of cosmic strings, which are loops in space-time that may have formed in the early universe and gotten stretched to large scales along with the expansion of the universe.

Re: Initial Tests Fail To Find Gravitational Waves

I'm not a physicist (a bum knee kept me off the varsity team) but I keep wondering if such gravity measurements can be affected by a vaguely similar sort of bizarreness as happens with the infamous "double slit" experiments.

That is, it affects both beams, even though it shouldn't. Or rather it doesn't affect either beam, even though it should.

Also I just keep visualizing a gravity wave as a space-time "flow" that not only affects the test mass but also encompasses the mirrors, the laser, the light beams, the photodetector, etc. So who knows what the result would be of that?

See? It's idle thoughts like those that cause women to look at me all funny and ditch out the back door of the restaurant during dates.

Gravity, like Light and electromagnetism is an all pervasive wave, depending on matter (Visible or dark/invisible) for propagation.

Therefore,detecting a Gravity wave is possible only if the instrument is equipped with a gravity focussing lens and a tunable resonating screen locted in a NON-Gravitational field.

We, unfortunately have to leave aside the "Noise" of Einstein, Newton and Stephen Hawking and think in an unbiased fresh manner, using contemplative meditation techniques.

H'm, that is theory atop of theory.....

I am not Physicist, but used to work with them, so I know they have habit of overlooking obvious.........

For light they bend the rules as is convenient at the moment, so it is either particle or it is wave.

I used to ask questions they did not know to answer, like:

If body which would travel at speed of light would have unlimited mass, and each mass have gravity in proportion to size of mass, then it follows that unlimited mass should have also unlimited gravity, right?

But according to theory about >>Black Holes<<, they are caused by enormous gravity, so what effect would >>unlimited<< gravity have on equally unlimited mass? Would that gravity compress that mass into its original dimensions, or even implode it?

I would say that someone has dropped word >>apparently<< from that quotation, as surely to stationary observer body traveling at speed of light would apparently have unlimited mass because its picture would be coming from all points of body trajectory at same moment, so for an extremely short moment it would look stretched from one horizon to another...........

Same thing was with postulate that nothing can travel faster than speed of light, as speed is referenced from stationary observer. Only, in universe as we know it nothing is stationary, if for nothing else then because planets orbit around Sun and sun orbit around gravity center of our Galaxy, if we ignore theories of expansion for the moment.... So two bodies traveling in opposite directions at speed of light, referenced from either of them, other body would appear to travel at double light speed.

That unfortunately prove that traveling at light speed and faster is not possible, unless there would be radars or Neutrino telescopes available to see what lies in front or what is on collision course with our ship.

Now in regard to gravity waves, we can observe some similarities with light rays in fact that gravity just like illumination, drop off same way, as square root of distance (if I remember it correctly from my Primary school days, and if that Law was not amended in the meantime). From this, I would conclude that gravity emanates from mass like light rays do, and since most forces come in pairs and there is not known opposite force for either gravity or light, maybe they are natural opposites, so maybe gravity is >>negative<< light.

Also, if gravity is directly tied to mass, then difference in specific weight of minerals should cause difference in gravity also. But we cannot just take precise scale and see if our standard weight suddenly become heavier in some areas (or can we?) because probably different gravity would influence our scale as well, so measurement are bound to be distorted........ Surely if we have perfect surface on constant distance from Earth core, then measuring height of aeroplane flight by laser would be able to show differences in gravity, provided there are ideal conditions in air and perfectly same speed can be maintained.

Now, if gravity falls with distance from the mass, then how could >>gravity waves<< exist? Next, in Solar system greatest source of gravity is Sun, so how can we detect much weaker waves coming from other sources in Universe? Also, gravity differences should be detectable even depending if Moon us in the sky or not, as we all know that Moon cause sea tides. At least, that was what we used to learn. But I wonder about it, as we have an sea island that have lake on it, and guess what? There are no tides on that lake! Perhaps it is because it is fresh water, or water mass is not big enough to >>feel<< pull of the moon, who knows, and tide is so small so it is not noticeable? That lake is unique since there is no creeks or rivers filling it, it is basically just rain water....... But then, ordinary scales would have to show differences in weight, depending on moon position in the sky, and we should be lighter when both Sun and Moon are in the sky at same time..........

It is interesting fact that if I measure my weight of different parts of floor that seems really uniformly flat, I could get differences of even 3 kg, and same differences are on same places, where distance can be as little as 30 centimeters.......

I still refuse to believe there could be so great differences on so small area, and I observed this long ago using mechanical scale, so I bought electronic one that is supposed to be 100 grams precise, but same thing happen again and again.......

I have a question: does Laser light also diminish with distance as ordinary light or it is something different?

Namaskar, Gurudevi!

I'm not a physicist either, but I've seen one on TV. Since physicists have (after several centuries of brilliant work) a rudimentary understanding of the properties of baryonic matter, that would give them at best a 4% advantage in understanding how the universe works, compared to say my golden retriever. The golden retriever knows about as much about the other 96% as they do.

As I understand it, the evidence for the idea that gravity is a wave traveling at light speed is based on observed orbital decay. That this idea emerged historically at about the same time that we discovered that light is a wave (traveling at light speed), it seems at least possible that this is an example of the availability heuristic. Maybe orbital decay is caused by weak interaction between baryonic matter and dark matter, dark energy, or licorice flavored pixie dust.

Maybe gravity doesn't travel in waves. Maybe it doesn't travel at all. Maybe it just IS. Maybe if you could instantaneously move a large mass in space-time, the gravitational effect would be felt instantaneously throughout the universe. Maybe that's why we can't move anything instantaneously in the first place. Remember, relativity describes the mathematical relationship between matter and energy, not the mechanism behind the relationship.

This is not a theory, it's not even a hypothesis. But I'm about 96% sure that our current view of such things may be wrong. We have been looking for gravity waves for several decades now. Maybe we will eventually design an experiment to demonstrate their existance. But then again maybe we're barking up the wrong tree.

Look at the idea from a different angle: If Einstein was correct, and gravity is the result of the curvature of space or space/time by massive objects, wouldn't gravity waves, assuming they exist, be collosal in wavelength? Any such "detectors" would never see an entire cycle of a gravity wave as they may be millions of miles/Km long. It would be like trying to hear propagating radio waves with a stethoscope. What does that say about gravitons?

Well, since Einstein time they discovered bunch of sub particles like Mesons, Hadrons, Quarks, Gluons etc. so there is no need for Gravitons also.

Maybe Gravity is effect of Gluons on macro scale, and we are simply >>glued<< to surface of our planet :-))

Maybe masive object do warp space, and maybe this is source of Time or they warp Time as well, but this has nothing to do with gravity?

Physicists claim that it takes great energy to produce fotons, but everyday use of light bulbs disprove them, as I pointed out to some of them, and needles to say that made them quite worried about their theories :-))

After I explained my theory about light as pair of particle and atom that cannot be detected, they built theory of >>Dark Matter<< out of it :-))

As I pointed out, if light is a wave, what is medium carrying that wave? Why energy of such wave do not dissipate with distance? If wave is circular and propagate in all directions equally, would not widening circumference of that circle dilute energy sent out as radius of that circle become larger and larger?

Why are we then able to see light of so distant Suns, when naturaly this light should become so weak as to be undetectable?

If Gravity do not diminish fast with distance from the mass, we would not be able to have Moon nor artificiall satelites in orbit around our planet, and of course Sun would long time past allready swallowed all planets, is that not so?

So HOW they expect to detect >>gravity waves<< from far away? They canot even measure gravity pull of the Moon or Sun, much less one from center of our Galaxy.

Nobody has yet explained even circling of Planets around the Sun, and if matter warp the space, then why are not all Planets at same distance from Sun? Still more paradoxicaly, smaller planets are closer to Sun and bigger are farther away, where surely gravity should have influenced greater mases more?

My only logicall answers is that theory of conglomeration of Planets and Sun is garbage, as originally there was just great mases of simplest atoms like Hydrogen. Space is still full of Hydrogen, and that is why new Suns are being formed still....

Then in close interactions between them they got glued first in pairs, and pairs started atracting each other, so greater and greater ball (or swarm) of Hydrogen pairs start forming. That added to mass and so gravity become stronger and stronger, pressing those atoms together. At one criticall mass, fusion of hydrogen atoms began, and new atoms of Oxigen were formed, and those reacted with Hydrogen to form water. Since process was not uniform, whole mass started to rotate, and centrifugal forces started throwing water molecules out of Sun. Gravity pulled them back and kept them afloat on Sun surface, because compressed hydrogen was more dense that H2O molecule. When in continuing process of fusion lot of water colected on Sun surface, eruptions of energy made >>islands<< of it on Sun surface. Because of energy eruptions, Sun was rotating faster and faster, and fusion continued in its core, producing heavier and heavier athoms, but process was not linear and centered on places where most energy erupted, as this same energy initiated fusion of more and more atoms together, both hydrogen and newly forming Oxigen, therefore Helium Iron and all other elements were formed and thrown to surface. At the begining, mostly there was water, which with Hydrogen started making more compley atoms and when there were enough Carbon atoms formed, carbohydrates were also formed. Those new elements localized into groups or balls by eruptions on Sun would occasionally merge, and then centrifugal force can sling them out of Sun, aided with some great energy eruption from Sun core that would coincide with their location.

That would explain why biggest planets are made of light elements and are mostly water, and why are they farthest from Sun. Eruptions were stronger in the beginning and not much heavier athoms were formed, so water balls were blown out farthest. As fusion progressed and heavier elements were formed, they were also occasionally been thrown out of Sun, but having greater mass and therefore inertia, they were not thrown so far away. If one study composition of planets, starting with Mercury that is closest to Sunn and most dense and going on trough Neptune which is mostly water, then it becomes obvious, is that not so? All other oxides and composite chemicals were formed in period of cooling planets down, so we have what we have now.

If I am right, Gravity waves dont exist, as they have never existed, and what we perceive as waves is just fringe effect of some other, as yet undetectable phenomena. If light and other form of radiation are waves, then it should be easy to make some kind of >>tuner<< that would be able to transform one kind of waves to another kind, and therefore at least IR radiation would be transformed into electromagnetic waves and from there we would be able to draw electricity, right?

With change of frequency we would be able to convert even visible light into electricity directly, and this would be cleanest source of energy. Also, if electromagnetic waves and light are same in nature, there is just question of frequency, and perhaps we can reverse process of creating high frequency electric currents that produce heat back into electric current from heat... But that can only be if present theory of Light is amended to postulate that there are just electrons which orbit faster or slower around some neutral atom we cannot detect, and which also travels faster or slower depending on its energy state.

This would explain how we are able to produce light using electricity :-))

That would then unify all forces and holy grail of Physics would be finaly found.

I am sure that using Black Matter as reactive mass we can achieve supraluminal speeds, because there is no logicall explanation why more and more energy expenditure is necesary to reach speed of light, unless there is something trough which ship is traveling that opose its forward motion that much more as difference in respective speeds of movement grows so energy is spent in interactions, and also because ship is parting this fluid leaving kind of wacuum behind itself, and energy expended cannot react to push ship forward as it would if ship is in vacuum.

But this would be easy to test and see if this is so, by puting tail rockets to be pointed outward and slanted in direction of travel, at >>walls<< of this >>tunnel<< ship is making trough >>dark matter<<, because walls of this >>tunnel<< would consist of even denser layer of >>dark matter<<........

I believe same principle can be tested on ordinary rockets and Jet planes, as air should behave same way, so perhaps lot of fuel can be saved.........

Changing of flight course would also be faster, just switch off motors blowing in direction where one want to turn to.........

Uh, stupid me, I should have patented this first before revealing it to everyone and some physicist can see what I mean and make himself Nobel Prize :-))

Sorry for spelling mistakes, again I wrote too much for speling checker to process.........

Regards from Croatia, homeland of great inventor, Engineer Nikola Tesla!
