.Ah ha ! Now ! you have brought me back from the brink ! By those two statements , my sanity has been restored! That is what I was taught , all those years ago at college . Binding energy . I don't seem to hear it mentioned so often nowadays. Maybe it is , but I am not in the right circles to hear it . Binding energy . The curve that Dips ( bottoms out ) at IRON . Why most of the matter in the universe will ultimately be , if it is not already IRON. The energy that is released or gained when elements Fuse or Fission to move up or down the Periodic table of elements . The Energy of the universe " Bound up in matter " . Einstein's pride and joy ! " There she Blows , you land lubbers " ----------------------------- BINDING ENERGY ------------------------------------ That's what's powering every star in the universe as it moves through the Binding Energy curve from hydrogen toward Iron and from every Supernova onwards up towards Uranium . And your Second statement -------------- MASS. IS --------------- Of course , as you say. '. Mass is ' That was Einstein's other break through . Mass is Energy and Energy is mass E = m c squared Or as you say. ( mass is ) Now how to unscramble that in my mind , so as to understand this gravity wave issue , and Space Time , " I am not so sure ? " Mike

I understand about the composites. But our root is still . Forces = fundamental bosons . and fermions = fundamental matter.. I am still trying to get a handle on what is going on in ' space time ' and whether, in addition to distance and time being present in space time . That what exactly is , in the first instance is the interaction from any large mass in space time , before ever it causes any waves , namely still at the distortion stage . ( the rubber sheet stage ) What is it ( the star or whatever ) pushing out the way ? ( or sucking in ) is it pushing distances and time , is it pushing by some interaction between the mass of the star and ' something else ' present in space time ' namely loosely spread mass type matter ' or something else? If it is interacting with something else to cause the originating distortion , what is the something ? Is it derived from fermionic fundamental matter , Bosonic entities , even if it modified to some composite particle . Also , if now we have this change, disturbance, collision , spinning black holes ? Where is the interaction going on ,in the already distorted ( space time ) . In other words if the things are now converted to complex particles , what exactly is being developed into waves ? The bit I am missing at the moment (. What exactly is being disturbed ) ? If NOT fermionic . What ? Or is it current belief that its nothing ? ( I can't reconcile that last one in my mind and understanding of matter! ) Mike

But it must be something of substance ! Vibrations and shock waves and mechanical disturbances , do not go through a vacuum , or empty space ...Surely ? . . So radio waves ( electromagnetism as waves ) seems to go through empty vacuum . But sound, vibrations , disturbances , as far as I know , do not go through space. Especially from 1.3 billion years of travel. If they did we could hear the sun ! The mechanical noise, vibrations and distortions that must be going on , on the surface of the sun . I am out in a park at the moment . I can not hear a ' dicky bird ' let alone a deafening cacophony from the surface of the sun. So what is the " Glupe " . Is it a mixture of low density matter , both Fermionic as Bosonic , virtual particles , quantum particles, neutrinos , dark matter, what is it ? Mike
-
O.k. All over the universe there is this ' Glupe' called 'space time ' its quiescent state is sort of settled with all the matter throughout the universe rearranged into its pits and peaks where concentrations of spinning matter , like stars , black holes , or whatever exert a gravitational distortion in this ' space time ' sort of transparent ' glupe' . Not many ripples to speak ok . Then a couple of black holes decide to crash in on one another in a dance of death , and as they near amalgamation the fun starts and large disturbances in the ' Glupe ' radiate out in all directions , presumably by some inverse square rule or ( inverse r to the 3 rule ) . And by the time the waves have reached us it's pretty small. My lingering , nagging , desire is to get my mental handle on the ' disturbed Glupe ' . I know. It's called ' space time ' but for it to be stirred up by these twirling black holes , like thin consume soup , it must 'BE ' something? Does/ is Fermionic Mass , in any way , present in this ' space time Glupe ? Mike

. I thought fermions were things like protons and electrons which have mass . And I thought bosons were things like photons and other interaction particles which did not have mass. But did have fields ( like electric and magnetic fields ) Is it the difference in spin , that gives it mass or is that just coincidence ? I can't say I know anything about super gravity and gravity waves for that matter , maybe I should look it up ! In some respects , I thought this is what all this experiment LIGO is all about . Are there gravitational waves ? And thus what are they like ? Yes there are , apparently. ! And what they are like I hope somebody will tell us ! Mike
-
O.k.Thanks . I get that specific example ! Is that the only way you get gravity waves . How about things like imploding stars going to neutron stars. Or things going to black holes? Exploding stars going supernova. First generation stars going supernova . The Big Bang itself ? All these are changing their 'gravitational density ' ( if that is a correct statement ) . Will these too emanate ' gravity waves ' ? It all sounds a bit like a flywheel which was rotating perfectly smoothly . But now it's 'big end' bearing , has gone worn or bust , and the whole flywheel is out of balance . Thus vibrating , giving a vibration to anyone sitting in the car , or on their motor bike ! ( ooh my Big End has gone ! A statement from Biker days ) . I still find it hard to see how these waves are travelling across space . Unless space is some form of distributed fermionic grid , full of fields and fermionic mass of some sort or another , even if the distribution is ' fine ', or not very dense ? ( I am using the word Fermion here to indicate something with mass as opposed to something Boson like , without mass , but with associated fields like electric charge and magnetism, etc . If I have got things right ? ) ( but maybe I have not got things right ?) ( unless of course, unless gravity waves are some new set of orthogonal fields , at right angles to each other in the way that radio waves, electro magnetic waves , are orthogonal , at right angles to each other , magnetic and electric . If that is the case ' what are the two orthogonal fields ? ' for gravity waves , mass field and movement field ? Or what ? ) Mike

But I can probe the force , or rubber sheet , because if I step out of my window , onto a sloping plank , I feel pulled down the plank . Something in my neighbourhood is distorting the 'rubber sheet ' . The earth I presume . Trillions upon Trillions of Fermionic matter particles . And I am a ball of many many fermions . If I had stepped onto a sloping plank out in space somewhere a long way a way . Far away from any suns , galaxies, planets etc . I would be able to go out of my window , stand on the sloping plank , and " I would NOT be pulled down the slope ! ( at least only very very minutely , by some far distant dark attractor ) I probed and felt a force ( Gravitational ) . Now how do I make a gravitational wave ? jump up and down ? No, I am serious . How do I make a gravitational wave . Do I need a supply of fermions. Or do I shake the Fermions I have . Do I stand on a vibrating platform . Or perhaps I find something else something massive many many fermions , that is oscillating ? Mike

.. A) what is a Gravity wave B) what is a gravitational wave I thought Electro- Magnetic waves were able to exist and travel in nothing , because they were sort of self supporting . Namely as electric field collapses to a minimum it induces a magnetic field to increase to a maximum. Then as the magnetic field collapses to a minimum it induces an electric field to increase to a maximum. Then all over again , and again and again . Like a skipping rope being flipped , except this is ' self flicking ' the wave moves off at ' c '. Gravity does not have two states like E-M waves does it ? Or does it ? So how can ' Gravity waves ' , travel in nothing , unless space is not nothing ? Are we back to ' the rubber sheet' . Somehow by the presence of mass , the fabric of space time is disturbed into a new shape , which has the effect of other masses falling towards the mass causing the disturbance. Thus all of space time must be some form of field matrix . This is General Relativity is it not ? Then as something by way of a large disturbance in a mass , waves move out across this field at ' c' . Is that what is supposed to be happening here , in this LIGO phenomenon. If that is the case we should be able to probe that rubber sheet of fields right here 18 inches away from my face . If I poke it with some means . Then look at a position of a few millimetres away . If I am able to poke it , I should be able to detect the poke a few millimetres away . What am I looking for to poke ? Mike Yes you are probably right ! Sorry . But even so the signal has to go , up and down , 44,000 miles . So at 186,000 miles per second . That makes a quarter of a second . So you are right the other delay must be in the system and cables. Even so the signal will take a second to reach the moon , and from the Egyptian Pharos building the pyramids to today to reach barely a quarter of the distance to the centre of our Galaxy . Mike The following two POSTs by. STRANGE and STRING JUNKIE are very good . I do not want to meddle with these points right now , as I need to retire for the night . Take up tomorrow .

. Mike Smith Cosmos, on 26 Feb 2016 - 7:20 PM, said:in Science News ( Gravity waves ) . I thought there was possibly some form of Fermion grid that pervaded space , and only responding to fermion style matter ( particles ) , and so propagating ' gravity waves ' ? I am comfortable with Electric Fields , and magnetic fields being set up , one way of another by some form set of components ( coil, plates etc ) into a space . These can be probed , measured , and with a little bit of electronics , an Electro magnetic oscillating field to be set up and a EM wave is produced Which races away at the speed of light . I believe these are derived from ' Bosons ' and produce ' Photons ' that travel at 'c' . Now what is the equivalent with ' Gravitational waves ' are they produced by ' Fermions ' : - how can one probe them , and send them off at 'c' ? Mike

Very informative quotations , thank you. I was of the mind that , it was not the gravitational mass , that was being picked up by LIGO , but rather the sudden change , say by collision or explosion , or disappearance of mass ( say by annihilation , black holes self distruction , sun supernova, etc ) , not the mere presence of mass and gravity . Is that not so? I am not even sure what the gravity waves travel in? Is it in the matter side of free space or what ? Ps. I thought there was possibly some form of Fermion grid that pervaded space , and only responding to fermion style matter ( particles ) , and so propagating ' gravity waves ' ? Leaving electromagnetism happy to do its business in nothingness as Boson style matter ( particles ) , propagating as light or Electromagnetic waves / photons ? If there is some mechanical vibration present here somehow ( I cannot see that ) , or perhaps only here on earth with all our surrounding matter . Then my hand held detector ( being in my soft flesh body and hand will be well insulated from vibration . I have been thinking in terms of the experiment , sometimes undertaken with plates at very small distances with atomic particles where minute forces are detected , with plates being pushed apart. These I know are electrostatic ( I think ? ) . However I was thinking more in terms of the ' Gravitational Waves ' being measured at similarly very short distances , perhaps . Now we know they are there ? But I am still not sure what the waves are in ? I will go and study up ' Janus' discussion Mike Pps . I am still of the opinion the speed of light is reasonably slow ( time - astronomic - wise ) . We do see reporters nearly tripping over themselves when conducting tv interviews with people abroad . The em waves move slowly enough to put a 2 second delay , by merely going some 22,000 miles up into space and back . I think I did the sums one day to see if I could set a pulse of Electro Magnetic wave off at one side of the lab and pick it up the other side . The delay was in nano seconds , which most oscilloscopes can cope with nanoseconds . Also the image of the Pharos erecting the pyramids will barely be a quarter way in toward the centre of our Galaxy ( Milky Way ) . Let alone toward another Galaxy . By these measures ' c' is comparatively measurable ( slowish ) .

Moving on from the Island of Human Endevour.
Mike Smith Cosmos replied to Mike Smith Cosmos's topic in Speculations
I think Richard Fortey, has shown this to be true in his recent series on the current changes happening on islands such as Madegasca. Madeira , Hawaii etc Here the top down approach is the driver , rather than the bottom up .

What was the system doing in principle ,to distinguish their gravity wave from ( the two collapsing black holes ) from general interference ? Presumably their signal was very very small ? And why could that not be used on the handheld version , I was describing above ? Mike
-
My illustration of the large steel ball at Pisa, is slightly ' Tongue in cheek ' . I am really asking , now that it has been established that there are Gravity Waves from some collision say of 'black holes or supernova collapse ' yet very far away in time and distance . . By the time , now it has reached us , it is very weak . Surely now we know they are there , we could surely get the same if not better gravity waves , by looking NOW , more closer ( like a meter away ) and by a mass collision far less substantial say two (2) heavy metal spheres. And that the measuring device could ? Surely be at a much smaller scale ? Say a meter or two ? Maybe I am wrong in my assumptions ? Mike
-
Now it has been proven Gravity Waves exist , could we not do a much smaller experiment , a lot nearer home ? Say with 10 meter arms? We could allow two steel balls to collide , one falling under gravity toward a much larger steel ball. And with a device not dissimilar to two pencils ( tubes ) at right angles , with some form of fibre optic detectors at the far ends , hand held detecting the ' Gravitational waves ' on an oscilloscope . After all ' c' the speed of light is quite slow , as demonstrated by reporters trying to discuss on T.V. , where the signal goes 40,000 miles return journey to the communication satellites. I think it would be orders of nanoseconds for the pencil type detector . Last time I was through Pisa Airport , there was a steel ball a meter across swinging from the roof 50 feet above , celebrating Galileo . You could let a steel ball from a ball race , fall from above , and detect the 'Gravity Waves' with your hand held " Gravitometer " ? Then we would not have to detect something super massive , coming from a massive distance , traveling for 1.3 billion years , so faint a signal as to require the large detector . ( now we know the Gravity Waves are there ) ? Mike

I think ' the sea ' is a good model , in its own right. Like most models , it applies in an aspect or two or more , but not in all respects. But , like skimming a curved , flat , circular stone , over the surface of water , enables one to get across the surface water far further than you could actually throw the stone :- so Your curvature of space , ;- and thus the trajectory of the stone is in fact across a slightly curved surface, caused by the gravitational effect of the whole earth on the water surface. I know there are a lot of mixed metaphors here , however it's good for possible explanations from diverse directions . After all we are talking of gravitational waves across 1.3 billion years worth of travel ! Mike

Well! I am not the expert , I am just a mortal being trying to get to grips with what's surrounding me ! But, as I perceive it ' mass is like the billiard Stick , that I have hold of . With a great deal of effort I give it a thrust and it transfers the thrust to the far end . At the other end is another mass ball that receives this thrust as an effect transferred by the stick . And pops into a pocket or goes on a further journey. So the cumbersome stick does not go anywhere . It just lumbers along with effort, momentum , mass , medium , and all the attributes and restrictions of mechanics . Whereas the effect , travels almost instantaneously , at the speed of light to the far end of my game . These words that everything is particles , I find , confuses me . It helps me if I think in terms of ' things of mass' and ' effects travelling at the speed of light or maybe at different speeds if the medium so effects ' But this is just a personal head model to help my understanding of ' the Nature of Things .. De rerum natura. Lucretius ' . Like at sea , the waves look as if they are travelling across the sea. The water ( mass) is going no where , just up and down . The effect ( wave ) is travelling across the sea as a packet of energy , finally breaking on some distant shore . And depositing its energy into/onto , distant mass ( a swimmer, or a sea wall, or a beach ) . Mike

..I am still struggling with the speed of gravitational waves being assumed so easily as 'c'. ( namely the speed of electromagnetic waves , light ,RF. .EM , etc ) . Other than some sweeping statement . " Nothing can exceed the speed of light " O.k. I can see , that the interactions of mass particles , being based on charge , or neutralised charge , being limited to some speed or other . And photons traveling at ' c ' being electro magnetic ' even though massless. But what is the mechanism of Gravitational waves based on , such that it is limited or exactly equal to 'the speed of electro-magnetic waves .?' What is the vehicle of their propagation ? When it is not based on Photon. Principles . Either ? . Has anyone made an accurate measurement of the speed of Gravitational Waves ? I thought this experiment was all about finding if they even existed? And if there is a ' rubber sheet ' . What does the rubber sheet represent . ( a gravitation medium ? Or what?) or are there gravitons zooming about like photons ? And how do they function ? Mike

The great Seas and Rivers of the Supercontinents.
Mike Smith Cosmos replied to Mike Smith Cosmos's topic in Earth Science
Just gone down to the Jurasic coast this morning . Lyme Regis . Here the base of an ancient river , sea, has today exposed its life , . Rocks tumble off the cliff. I picked one up off the beach . It had a crack on its side . I put a tiny stone in the crack and .. Bingo a fossil. Last saw the light of day 100,000,000 or so years ago The fossil hunters out today The Jurassic Coast At home , studying up the evidence .

That's fantastic , so my idea of an image history of the universe is not too ' far fetched ' Mike
-
Sounds really good . Will the images be up to the quality of Hubble space telescope but only exploding , or violently moving matter ? Do hope so . Now they have had success , they can get more money . Mike
-
. O.k. That is great ! But I imagine they can compute exactly which direction , the signal , did in fact come from? So as to project a three dimensional picture ,if necessary ? I hope so ? Then we can look forward to some gravitational images of the exploding universe? Mike
