Which of the following could be the "true" carrier of spacetime:
The Neutrino? The Photon? The Higgs boson? The superstring? Photons seems to have a basic structure, and are carriers of info. Neutrinos travel faster than light (probably). Higgs bosons compose the Higgs field and give mass to all other particles. Superstrings are only theorized, but are infinitesimaly small and elongated. |

The only slightly possible answer to those could be superstrings!! think about it...
- Neutrinos: millions travel through earth every second... i think we would notice if they were spacetime - The photon: this is simply a force carrier for electromagnetic... if the photon was spacetime then so would be gravity and the strong and weak forces - The Higgs boson: still only theorised... remember that! Also the boson itself couldn't be spacetime as it is a virtual particle like the photon. - Superstrings: This could be possible because they are said to be of the smallest length to hold up in physics (planck length) but they are still highly theorised and so very speculative. Spacetime fabric is most probably just a vacuum but with more abilites in deep space than we have ever considered possible here on Earth! K_ |

And I've tried to correct your misunderstanding of strings a few times. Strings are the particles. The problem with general relativity is that it breaks down at the zero size of the supposed classical particles. This is corrected/dodged by giving all particles a minimum length (i.e., a one dimensional string) to avoid the accompanying infinities that result from using zero as the particle's size. This is the Big question IMO, though. If we can ever answer this one we'll develop a significantly deeper understanding of the universe. I'm leaning toward emporium's vacuum answer, but then how could gravity curve a vacuum? I agree that it has to be made of something, I just don't know what. I do know that it isn't anything you listed, though.

Agreed John L. Perhaps vacuum fabric that can interact with gravity but nothing else. Perhaps 'graviton' is vacuum but which only creates any interaction strong enough to measure when not already under the influence of gravity ie. Earth feels this vacuum gravity but we do not have gravity because we are under the ffect of earth's gravity. Highly speculative theory but hey, who would have ever thought black holes could be real?!

Hi all,
I may be wrong, but I understand gravity to be the result in the curvature of space. It looks to me like you guys have the impression that gravity is some sort of wave, particle or something. For all the reding i have done, what i have come to understand is that if gravity has a for of a wavecule or particle - then we would have come a long way into understanding most of everything else - including quantum gravity - though we would not be riding our flying cars any time soon. As for the actual composition of spacetime, one basic bit is space and time!! Then the next logical question is, what is space made of. I have read "vaccum" among other listings. In one documentary where some of my most fav science horeos featured (e.g. Stephen Hawking) they sighted a theory that if you were to observe the vaccum of space close enough, you will notice that its not empty, you will notice that it fizzess and is almost "alive" as though you were looking at a boiling pool of mercury. What its actually made of is something else - another sighted an oil-droplet like phenomenon that seems to be part of the fabric of space. Look deep enough, end you will start heading into quantum physics territory - an area i look on with great joy and excitement of possible future developments. SO! what is space made of: Boiling stuff that scientists are still trying to work out what it actually is and prove beyond double or theorization of its components and existence. I love this discussion board, you guys keep it going. I will be reading on from here at home in South Africa!! |

Alright, here 'tis! This is just a couple of paragraphs from the huge thing, but I hope that it'll be helpful nevertheless.

StarLab,
Thank for the very detailed set of quotes, i always love reading stuff about our universe. But not to risk sounding condescending, but I think this thread seeks to get understanding mostly about the composition of space. Some here have said vaccum and sighted particles and things. But, my question is - without spacetime, there cant possibly be a medium for these particles you are talking about to exist in. So... we land again in the center of the question, what is the compositions of SpaceTime (except for the obvious main componets being Space & Time). If space is made of vaccum, then what is the vaccum made of - it cant possibly be made of nothing, after all space has been equated to nothing more than the foam on a seashore washed by seas that come forth from the great oceans of Zero Point Energy Fields that the universe takes its energy from (i could be mistaken). It is also known that the universe is ever expanding, if it is, the unaccounted for mass that is creating more space through its creation is somehow drawing its enegry from elsewhere. With the new "much speculated" funnel shape of the universe, i begin to wonder if scientists are not being methodical in their research. Shouldnt scientists try to answer the most basic questions first before trying to tackly super strings...? Really, what is space made of, i would really like to know, after all - there is so much of it out there. If something bends through the presence of a massive object thus creating an effect called gravity thereby slowing or altering the passing of time itself exists - then it must be studied and looked at much closer. Anyway... great insert though, i look forward to reading replys to my post. |

I highly suggest you pick up a copy of Greene's new book, Fabric of the Cosmos. The book is all about what you're asking here, the nature of spacetime.
The first 2/3rds of it gives one of the best descriptions I've read of all the current physics theories, such as inflationary cosmology, Higgs ocean, etc. The string theory stuff is there, but it takes more of a back seat since Greene did such a thorough job in his first book.

Ugh...interesting how, more and more posts, means farther and farther away from the original question.
If i had to pick one of the four choices...i would be in big trouble. Because, i really cannot imagine psacetime to be carried by anything - especially particles. In general i always lean toward my own assumption that space-time is a dimmension of it's own - one, i might add, that we totally missunderstand. But anyways...I would have to pick the superstrings (i think i got their name right...). Simply because they are unknown and uncertain enough to pose a possible relation to spacetime. There! If what i said is rediculous:wacko: & laughable ...forget i ever said it...I'm in hiding h34r: Peace!

Good question. I'd say it's a tie between neutrinos and superstrings.

Finding out the exact compostion of space-time might be the greatest scientific advancement in history. Perhaps more important then discovering alien life or finding out what came before the Big Bang. If we can find out what it's made of, then we can start to manipulate it...

Three year necromancy? Is that a new record?
More specifically, is necromancy even a violation? I known some think it is, but I'm not so sure. I'd be interested in finding out, though... In the meantime, I think it's more of a case where spacetime is. |

You want me to identify a particle as the carrier of spacetime and you don't offer the graviton as a choice?
I refuse to select any of the choices from the list as a possible answer. BTW, How do people manage to go looking for these old threads? |

Probably from the list of 'similar threads' that often shows on the bottom of the page. Forum should ask: "ur about 2 reply to 000oold thread.. r u sure? (yes/no/dunno/wut)".

I have to wonder if, beyond a point, it even matters "what" space-time really is.
As in, the environment is so alien to our intuition and to our ability to examine that "what" isn't even a question that makes sense. Or maybe I just don't possess the tools required to describe it meaningfully ![]()

Perhaps, but asking why in this case, is a bit like when Edmund Hillary was asked why he scaled Mount Everest. "Because it is there..." he replied simply..

Mallory, not Hillary, supposedly said that.
http://en.wikipedia.org/wiki/George_Mallory Hillary said something else ![]() http://www.abc.net.au/worldtoday/con...03/s860601.htm "GILLIAN BRADFORD: Another member then misquoted Sir Edmund Hillary as a famous user of the word "bugger". National MP Gerry Brownlee thought Sir Edmund had said "we knocked the bugger off" when he reached the top of Everest, when in fact he said "we knocked the ******* off". I once bumped into Sir Edmund Hillary in Stanfords map shop in Covent Garden, London. One of my heroes when I was young. I was too shy to speak to him ![]() |
