I see now this thread, to bring it back to the OP ... Well, in Antarctica, BICEP has found some evidences of "fossil" gravitational waves. http://www.cfa.harvard.edu/news/2014-05 I quote:
Einstein's Theories in GR and SR have all mostly been proved so no Gravity is not a secondary fundamental form of energy....it is in fact the alteration in a one dimensional fashion of Space-Time. AboveAlpha - - - Updated - - - This ould be nice but their claims are HIGHY SPECULATIVE. A LOT more has to be looked at first before they can make this claim. AboveAlpha
Absolutely, the direct observation of gravitational waves is predictable for a not so far future, when systems of satellites, orbiting around the sun [following the Earth], will be able to use the principle of interferometry to get hyper definition detections of the space. The Laser Interferometer Space Antenna [LISA] will be launched within 5 years by NASA / ESA [European Space Agency] and it will work for other 5 years in the space. The purpose of this mission will be just to detect the gravitational waves produced by very energetic events involving great masses moving at high speed [binary star systems wit huge stars, for example]. LISA is a system of 3 satellites [ESA] which will reach the space thanks to a NASA launcher. Then the 3 satellites will form a triangle with a distance of 5,000,000km among the satellites. Lasers will measure the relative positions with absolute accuracy and any passage of gravitational wave will be detectable.
The great question here is doesspace-time instantaneously adjust to redistribution of Matter....or does it occur in Gravitational Space-Time Ripples or Waves at the speed of light 186,282 miles per second? Big question. But hey....there are still members on this forum that think that only a 3-D Universe exists even though Quantum Mechanics is showing us a minimum of 10-D or 11-D. AboveAlpha
Well, there have been attempts to measure an eventual speed of propagation of gravity, but scientific community hasn't been that persuaded. I indicate a famous one: http://www.phys.ufl.edu/~cmw/SpeedofGravity.html Personally I share the remark that gravity has got the capability to deform space-time, so that we are discussing about the speed of propagation of something which, moving, deforms the system of reference we should use to measure its own velocity! Then I would underline that gravity is a property of mass, but mass [CERN tells us this] is not an innate property, but it's acquired by the interaction with the Higgs field. Then, once this interaction has generated mass, gravity is substantially eternal and the extension of its lines of force infinite. So far, since we cannot observe the eventual virtual particles of the gravity field, we cannot infer that they can decay [it seems they don't, until mass is there]. So that, being the potential extension of the oldest gravitational fields equal to the extension of the space time [mass exists since the very beginning of the expansion of the universe], it's well probable that to talk about propagation in their cases is a nonsense. Let's think to the gravity field of Earth. 4,600,000,000 years of life. Ok. It's spherical gravitational field should have reached a radius of 4,600,000,000 light years. So also in the case of the objects in this galaxy [and in many others in the nearby] it's a nonsense to talk about the propagation of their gravity field. It's already there. What's moving, it's the center of attraction, so it's the intensity of the gravity field to change, it doesn't move, it's already there. P.S. About dimensions, I'm with M-Theory and I count 11-D [waiting for someone who will theorize some further dimensions!].
This is probably the core of the question. Since the masses [in motion, since in the universe nothing is firm] follow their trajectories with their existing gravitational interactions, nothing happens. The Earth orbits at high speed around the sun, but this doesn't mean that we feel the solar gravity with a relativistic delay [since the relation is stable]. But let's make the extreme hypothesis that a powerful gravitational wave coming from the crash of two supergiant black holes moves the sun. Like electromagnetism tells us [and if gravity is a quantum field as well, it has to work in the same way], when a source of the field has moved it creates a perturbation in the field which propagates at the speed of light. So that if the sun has moved by a gravitational wave [which doesn't hit our planet of course], we will note it in about 8 minutes [the relativistic delay corresponding to the distance between the sun and our planet].
Nice post...good job! Here is the thing....we know that Gravity cannot be a force but rather an EFFECT....one specific to a One Dimensional Expression. And as you stated the Earth's Gravity Field Propagation should have reached about 4.6 Billion Light Years by now. But what we do know is spiral Galaxies do not have enough normal matter to hold them together. It is the Dark Matter which allows a Spiral Galaxy to spin and not loose it's stars on the outer rims. I am inclined to believe that Dark Matter is the ability of certain Quantum Particle/Wave Forms and their Fields...Higgs Field....to exist and transfer between alternate Hardon Constructs of infinite alternate divergent states of one another within a single Universal Grouping within a Multiversal System. Multiversal Theory is not Many Worlds or M or Brane Theory. AboveAlpha
The exotic nature of gravity as force is just the most intriguing subject in modern physical research. The quantity of Dark Matter in the universe seem to be well more important of what in the past researchers thought. Its role is still all to be studied and theorized in functional models [really functional models]. Anyway, I cannot be so optimistic to imagine we will get conclusive answers during our life. It will be the field of discovery of future generations of space explorers and scientists.
Back in the 1980's the U.S. was building the DESERTRON...a massive Particle Accelerator under the Texas Sands...so large it makes the current LHC look like a Doughnut compared to a 747 Landing Tire. We were almost finished with this $20 to $25 Billion Dollar Project and then we just STOPPED! The Unibomber Ted Kazinski a Physicist thought that the Desertron was so powerful it would create a Black Hole large enough to swallow the planet. Now Micro-Black Holes are created all the time when Solar Radiation impacts our upper atmosphere but still...spending $20 to $25 Billion and then when you are almost done....shutting down the project....well something was up. Because of what I do every now and then I have a NEED TO KNOW.....and what I know now is....the reson we stopped building it is we already knew the answers. AboveAlpha
Hey, AboveAlpha, maybe your infinite multiverse is squeezing itself into the spaces from cosmic expansion? The cosmos is expanding at an accelerated rate except where gravity gets in the way. Maybe gravity is our anchor for reality? If so, how do we know that the other galaxies we see are compatible with our divergent state of reality? I guess that depends on how your "divergent state" breakdown works?
Wga....you are killing me but I love you anyways! LOL!!! The other Galaxies in our Universe have the same physical laws of nature that we have. Dark Energy could be in my opinion the effect of the Anti-Higgs-Boson Field Interaction within our Universe but these Ani's exist in other Universes within the Multiverse but must be able to be interconnective to a point. AboveAlpha
Gravity moves at the speed of light, according to general relativity. Unstable orbits of pulsars are evidence of in favor of that.
How could I be so stupid??! I'm not ignorant of the fact that the Universe has the same natural laws everywhere. Well, I never said I was smart every day... Golly gee, Billy Bob! Let's find out what happens when we put our finger in the electrical socket... ZAP!!! Anyway I was looking for hooks into the multiverse, because without them we'll never know what's out there. Will we? Oh well, maybe I'll have more luck with the news article I saw this morning: The Quantum Cheshire Cat: Scientists separate a particle from its properties. No, it's not really about the multiverse.
That's what Einstein postulated....but here is the catch....if new Space-Time is being created via Universal Expansion....and it is speeding up....then I can see how the increase of distance between Galaxies at the very Universal Edge would effect the newly created Space-Time at.....c.....Velocities. BUT......if the creation of this New Space-Time is incongruent with standard Universal Geometry then...c....Velocity Gravitic Waves cannot apply. AboveAlpha
Hey....no big deal! I have my DUH! moments. Story.....I am 19 years old at a club and legal to drink alcohol. I am just ending my first year of studies and also ending my first year of TRAINING. I am a very good looking tall and muscular 19 year old kid and two very lovely girls walk up to me and one of them say's..... "Baby....you are HOT! I don't mean to be so forward but my girlfriend and I have a nice carpeted VAN outside!" MY REPLY?......"Oh...that's nice." DUUUUUUUHHHHHH MOMENT!!!!! Her friends reply....."Sweetie.....she is the nice one....I am the NAUGHTY one!" My Reply?......."Oh....excuse me....my turn to play pool." AND I WALK AWAY BECAUSE I HAD 50 Cents on the POOL TABLE!!!!! Then....about 60 seconds goes by......AND IT HITS ME!!!! DUUUUUUHHHHHH!!!! We have a van....Oh...that's nice. UNBELIEVABLE!!! HOW MUCH MORE OF AN IDIOT COULD I HAVE BEEN!!! They were both SMOKIN' HOT TOO!!! DUUUUUHHH!!! AboveAlpha
Oh no problem I'm okay. Say, I think I might have heard the story with you, the two girls, and the van before.... Or maybe it just happens to you a whole lot. LOL!
Nope...just once and I might have posted that story before. I want you to read this. LINK....http://www.politicalforum.com/curre...hunter-killer-unit-smash-islamic-state-8.html Post #74. Thanks. AboveAlpha
There's no guarantee the laws of physics apply everywhere. http://www.sciencedaily.com/releases/2010/09/100909004112.htm http://www.newscientist.com/article/dn19429-laws-of-physics-may-change-across-the-universe.html However, even on the other side of the universe, I wouldn't put my finger in an electrical socket. I take a "you first" approach on introducing significant electrical charge movement within my body.
Yeah, because sticking your finger in the electrical outlet is very stupid! Anyway, I don't know what's on the other side of the universe, except more space stuff.
Well this is the cool part. Dimensionality and distance Space and Time only exist within the Universal Construct. Thus this means there must be INFINITE UNIVERSAL CONSTRUCTS.....as distance as far as Space-Time are limited to a Single Universe as the matrix that a Multiverse is....is Unlimited. AboveAlpha
Mystery of the moving rocks in Racetrack Playa officially solved!!! It was the ice all this time: Mystery of Death Valley's moving rocks solved. In theory there are infinite universal constructs, but that's on paper. Here and now, in our universe all we've got is a list of constants. We already got take-out from the big bang. If you want something else and call up for delivery you'll get the flying spaghetti monster. But I get what you're saying, I really do. That's why I sometimes look for news of hooks into the multiverse system...
WGA....I would NEVER lead you astray...you know that right? Try to look at it this way. The reason why Human's have such a tough time believing and understanding in INFINITE and FOREVER....is because we see things having a BIGGING AND AN END. But that is not how the Universe or Multiverse works. Some people ask me..."Why do you place so much viability in an existing MULTIVERSE?" And I answer them like this....."If a person kept counting either in whole Positive Numbers....ie...0,1,2,3,4,...etc...or counting in whole Negative Numbers....0, -1,-2,-3,-4,....etc.....and they did this till they dies and then their children took it over and so on and so on.....in either direction....would it ever end? Answer.....NO! The key words are INFINITE BALANCE. Now the word Balance would infer a LIMITED QUANTITY, MASS, REPRESENTATION...ETC....on each side of the scale and in our Quantum Mechanics Based Universal/Multiversal Scale....there is a POSITIVE AND A NEGATIVE. It is hard for me continue verbally without using Mathematics....but reast usured of this....since SPACE-TIME is in reality NON-LINEAR AND IS NOT MUTUALLY EXCLUSIVE.....you and I will LIVE FOREVER!!! Why? Because....One Dimesionally....all Space-Time is the same Space-Time and all individual Universal Dimensionality expresses itself as a Physical Law of the Universe. I HOPE you can understand....Math makes explaining easier but no one understands the Math. I had some Moderator on this Physics Forum give me a hard time and I started posting...actusally Copying and Pasting the Math as I could not figure out how to represent all the Mathematical sysmbols on my keyboard....and it shut him up fairly quickly. Nothing really dies or is lost....it just transforms. Like I said...I have always found comfort that when I die....or when anything dies....everything becomes FOOD for everything else....thus we live on both in a Linear and Non-Linear Manner....because in a Non-Linear Manner...you and I will be having this discussion for all time...and TIME...has no begiining and no end...it is really CONCURRENT.
