Just wanted to stick an unlooked edit in here (the thread will be discontinued as it appears the forum is, in general too simple to be ready for it yet), but when a thread like this gets hardly any interest, and yet some unfounded thread concerning itself with a 'balmpot' interpretation of creationalism  (IMO and stated here on my thread - delete this thread and.....'i'll find you, i'll find your family.....you get the general idea :D), gets - up to the present time of writing - over 3 pages it just goes to show how little we have evolved as of 2015. It never ceases to amaze me how utterly backward people still are in this modern age, [particularly in the states which appears to have a chronic problem with it - the supposedly wealthiest, most advanced, most developed country on the planet - utterly staggering says deena]. 

 

Ok, I'm just starting up a thread for people who might be interested in quantum cosmology, I am not trying to be clever, it's my major hobby and I start this thread up in some shape of other everywhere I go so if you don't see the point of it being here all I can say is tough!! switch channels like u would do with your television because you don't seem to have much of a problem doing that OK.

 

Good.

 

Right, this first documentary (it's actually the second in the series out of 3 in total but I watched it first and I want to say a little piece in my own words beforehand for each one - I will release them weekly), we look at the theory of Sir Roger Penrose, which deals with a kind of cyclic big bang for want of a better description, he talks about the very large being similar to the very small (conformality), entropy and black holes, signatures of CCC (cyclic conformal cosmology is the full title of his theory) in the cosmic microwave background (CMB) - basically can we observe any direct evidence of it, and a multitude of other incredibly interesting concepts and ideas I have to say - in a way you will be able to understand, it really is so well explained at layman hobbyist level (people like me), it's bursting with fascination.......

 

 

Here's a funny thing, I found the series a few days after I wrote this somewhere else on a forum - my own ponderings last Tuesday, see how Sir Roger brings up a number of the issues I raise and answers them immaculately - My biggest gold star has to be when I question whether Steven Hawking was really wrong about loss of entropy and black holes - I mean the entire scientific community now says he WAS wrong and there I go questioning the whole of the scientific community only to fijnd that actually I have 1 backer - and that happens to be the mega-weight in quantum science himself Sir Roger Penrose (I was well happy with myself over that I must admit  ;)

 

My post as it was......

 

Black holes, Hawking radiation and the eventual fate of our universe
05 May

Damn i feel so anxious after drinking - it really is nasty and I shall be abstaining again for a long period of time, but maybe if I can use this profile as a kind of thought sketchpad I might be able to distract myself away from this inner worry I feel.

 

The vacuum of space - well it's only a vacuum 'on average' you see quantum theory can only predict things in terms of probabilities, and a vacuum is 'probably' a vacuum with this amount of % it has to do with uncertainty. So what else could there be? well quantum jitters for one - the breakdown of a quantum field results in the instantaneous creation of 'virtual particles' this is allowed so long as these virtual particle-antiparticle pairs instantaneously annihilate each other thus restoring the balance of 'nothing an average'.

 

Black holes - now here's where black holes play a part, if these spontaneous virtual particles present themselves near the event horizon of a black hole (the point of no return from which even light cannot escape), then the anti-particle (which has negative energy, I know it's a bit of a headfuck but just accept it - energy can also be negative ok, like a photonegative of a picture let's say) may end up falling through the event horizon (it is always the anti-particle which is attracted in to the black hole, can't exactly remember why but nevermind for now), once in it cannot get back out and spontaneous annihilation cannot occur - the other particle is then radiated out from the black hole and it is this that we know as 'Hawking radiation' It means a black hole must have a temperature, no matter how small. Anyway - because the antiparticle has a negative energy it acts to erode, or evaporate the black hole and given a few trillion years or so would completely dissipate it.

 

So here's a little bit of 'thoughtpad' from deebna I cannot verify my ponderings - they are just that, ponderings........

 

It is now thought that every galaxy has at its centre a supermassive black hole, that's every galaxy, that is what the science is telling them - black holes are necessary for the creation of galaxies in the first place - and what do they do? well they munch a lot of gas and dust, the odd star that is unlucky to be in the wrong place at the wrong time then just as your tummy after a hearty meal - they expand outwards, the event horizon grows, entropy is conserved and can be directly related to the surface area of the event horizon (another topic for another day, but was indeed the basis for the black hole wars between Steven Hawking and Leonard Susskind - Susskind was eventually shown to be right entropy is conserved so sorry about that Steven!

 

What I must ask is this - will the supermassive black hole eventually devour the entire galaxy that revolves around it (we go around it like a carousel once every 120 thousand years or so, the milky way galaxy is in a state or rotation about its centre u see) oh and another thing - the only stars you can see when you look to the sky every night are ones which belong to our own milky way galaxy - the eye cannot see beyond the boundaries of that. But if the growth of a black hole is perpetual - more matter in = stronger gravitational attraction = more stars fall in = expansion and stronger gravitational attraction = more stars............ Then it must be entirely conceivable that a supermassive black hole will eventually eat everything up, completely devouring the galaxy.....and then? well anti-particles enter due to quantum uncertainty and a very very long drawn out process of evaporation - does it eventually, like so many forumers i could care to mention 'dissapear up its own *** in a cascade of nastiness? and what of the second law of thermodynamics? what happens to the entropy? is this a direct violation, was Hawking right after all?? And if this was ho happen in every galaxy what would it mean for the fate of the universe? will there eventually be nothing left other than a sea of hawking radiation? I suppose it all depends on whether the universe will continue expanding forever or whether it will eventually succumb to gravity and fall back in to itself in an almighty big crunch - all I can predict is that the rides going to get rough and nothing lasts forever - not even nothing lasts forever :-)  we're all doomed aren't we, this hasn't done much for my anxiety lolo but acceptence of ones fate is always an important stepping stone to overcoming isn't it.

Just want to carry on a little down here, it is allowed.....but if this conformal 're-cycling' if you like has no beginning and has been going on forever and will continue to go on forever then there are only a set number of ways you can shuffle a deck of cards - at some point the sequence will be repeated, no matter how many different combinations there are for a deck of cards because there are a finite number of cards in the first place (52) then this means there are only a finite number of arrangements of these cards in a deck and the sequence must be repeated at some point. What's more if you are shuffling and re-shuffling the deck of cards an infinite number of times that means every sequence will be repeated again an infinite number of times - now if you consider atoms to be cards and the visible universe to be the deck then there can only be a finite number of arrangements of these atoms before the sequence is repeated - do you ever feel like you have been here before? I always feel as though i'll be here again personally - ever the optimist  :D

 

The nutty bit(ch).....

do it today - jump off a carpark!!!!

 

..........and be enthralled as you are instantaneously reborn (once u die time ceases to exist until the next time 'your' particular sequence repeats u see - no matter how many googleplexes of googleplexes of years it takes - you won't have to wait through any of that because that particular train of time won't exist to you - you will just get fast tracked to a pi55ed up night in blackpool/ baltimore in 1970 [the moment of your conception to the masses here :P ] ....... but BEWARE and make sure ur life is an interesting one, imagine how many times u r going to do it again - live for the moment and not for your pension is wisdom  ;)

I cannot get my limited brain power around this one. If there are eons continuing one after the other with no beginning and no end how did it all start? My mind will not accept that it was just there and always has been there. Sir Roger Penrose can say it has no beginning or end because no-one will ever be able to prove him wrong within his lifetime. I think I will have to stick to playing Golf games - this is way out of my league

Thanks for coming in and commenting, it's really not 'all that' at top level - before the maths starts - I hate the idea of dressing these topics up as unapproachable unless u r really clever like me *smugs* because i'm not :D  . The concepts can be counter intuitive but when you read on and learn about some of the most incredibly bizarre behavior going on down there at the quantum level - things that can and have been demonstrated experimentally - then you realize the world is not really as it appears, the reality will always be out of our grasp and we are for all intents and purposes living in an illusion...... it just keeps me riveted.

 

Thanks again for giving it a look-in :D

It is true that science has started to point to things that at one time would have been considered 'mystical' indeed, and science has been guilty of 'smug' itself - they were smug at the turn of the 20th century, they thought they had it all locked down, in their pockets, Lord Kelvin proclaimed that there was nothing left to discover and Physics was over....and watch out!!! Boltzman opened up the gates of quantum science and Einstein laid the carpet of spacetime at our feet and we knew nothing once more..........then even as late as the early 80's Steven Hawking was banging on about N=8 supergravity and how they were within 10 years of the grand unification: the long sought theory of everything......more egg on face followed and N=8 was thrown out of the window!!!

 

There has been one of those 20-odd year lulls as of recent, they have happened before, a period of stagnation does tend to precede an era of rapid and profound progress and as we have seen with hints at CERN of the Higgs boson - yes I do say controversially 'hints' there are still issues with what exactly they have found, though it looks like a Higgs it has not been completely pinned down - there are close relations of the Higgs which also remain candidates and it will take further experiments which are just about to start again as they ramp up that collider to a whopping 13 TeV (it's just big OK!!) we are all hoping these never seen before 13 TeV collisions will open up new gates and lead to new science and possibility - but throughout all of this, all the frustrations of science (yesterday was right now it's wrong, yes it gets frustrating), but there is one thing that sets it apart.....

 

Science can explain things, it can prove things and there is no other area of human thought that can achieve this - it can explain and prove why we 'may' never be able to grasp what is the true underlying reality (but what do we know in good old 2015  :lol:  that was before the invented the flux condenser  :D

 

....and the only way you will get cut to pieces through questioning a popular held scientific belief is through hard questioning via a panel of experts  :lol:  so lets keep the comments all about the science here - above all it's a lot safer for everyone  ;)

Deena, what do you think the implications are of the Higgs being at 125 GeV?  I saw a documentary on the discovery of the Higgs and they said they were either looking for 111 which would support supersymmetry or 144 which would support the multi-verse, but they didn't say what 125 mean't.  Maybe they don't know.

Wouldn't it be cool to figure out some way of negating the Higgs field and be massless?

Hi, fascinating stuff - do u have a link to the you-tube of that documentary?? I'll look out for it, would love to know how it can be related to a multiverse !!

 

Negating the Higgs field - ask a ghost lol!!!

Heh, funny :)  The video is on Netflix, called Particle Fever.  Its a documentary on building the LHC leading up to the discovery of the Higgs.

I just watched that docu - isn't it interesting how 125 GeV is neither confirming supersymmetry nor multiverse, that is indeed very interesting, lols - if it had to be at a value that would create more questions than answers then u can trust particle physics to deliver!!!

 

My thoughts?

 

Well what 125 GeV does say is that the higgs is right on the boundary of stability, just to take a snippet elsewhere on the net... 

 

 

This isn't the first time that physicists have said the Higgs boson spells doom for the universe. Others have calculated that the Higgs boson's mass would lead to a fundamentally unstable universe that could end apocalyptically in billions of years.The mass of the Higgs boson, about 126 times that of the proton, turns out to be "right on the edge," in terms of the universe's stability, Carroll said. A little bit lighter, and the Higgs field would be much more easily perturbed; a little heavier, and the current Higgs field would be incredibly stable.

 

Now going back to the Roger Penrose documentary above - he does explicitly say that the Higgs field may eventually fade away such that the mass of the universe becomes zero, thus enabling a match to the conditions required at the next bounce, certainly the idea of a barely stable higgs particle plays in to the hands of a potentially cyclic universe - a multiverse in series not parallel, neither one nor the other but would allow for supersymmetry.

 

Of course the answer is we don't know yet let's see what further developments bring as they ramp up the power, but at the very least it doesn't discount what Penrose is saying does it.

 

Oh and at the end of that documentary it advertised another interesting docu called 'who's afraid of a big black hole - i'll paste the link here because i havent watched it yet, sounds just up my street though.

Thanks for your interesting question Crow - it enabled me to do a bit of research and have a little think, relating it to the CCC model

 

rewarding day indeed  :D

Ok we delve a little deeper this week in to an area known as quantum loop gravity, I am only recently read on this area and so my understanding of it is not yet comprehensive enough - even at a laymans level - to be able to present something in a smooth logical progression in order to explain things - so just hear me out, give me a chance and let me know if i'm talking gibberish at the end, lols!!  

 

The first thing is that as we go back further and further in to the past and the universe is seen to be contracting - galaxies are coming together, merging, energy density is on the rise, matter is becoming more dense as it crashes together - to a point we know as the big bang singularity which states all matter in the universe was once compacted in to an infintessimally small point of infinite density and the warping of space time was infinite - like a very sharp, err prick (giggles) on an elastic membrane......

 

That's if you go by the principles of general relativity - and the big point is that general relativity breaks down at the big bang so the singularity is only a projection of a theory which is in itself invalid and not equipped to0 deal with the conditions at ground zero.

 

Hence the need for a quantum theory of gravity....

 

Quantum loop gravity is based upon these loops of energy known as 'wilson loops' and a most important aspect of the theory which distinguishes it from string theory is that it is background independant - strings in order to vibrate require a background in which to do so, but by establishing networks of these wilson loops we create the very fabric of space itself from them similar to a knitted cardigan the loops themselves form their own background they become or are the quantum excitations of the gravitational field itself ?? am i winning or losing even myself here  :o  :wacko:

 

Anyway if we accept that this is in fact space then space becomes discrete, i.e. quantised - it consists of a minimum unit beyond which space and time has no further meaning and it is because of this that quantum loop gravity does not predict a singularity but a square membrane of approximately 10 planc lenghs in length.

 

Because of this finite size QLG (quantum loop gravity) predicts that there could be no big bang but in fact a big bounce (familliar from the penrose episode above?), entropy or lack of it at the very beginnimng is explained away as due to quantum mechanical effects that act to reset everything and to be honest I get a bit lost about the specifics and am at this point still unclear in my own mind to feel comfortable....

anyway here's the documentary, I hope you enjoy and if there are any experts in the field of quantum loop gravity I for one am all ears to your explanation of it as it relates to the universe and its first moments, i.e. quantum loop cosmology as it is known...

 

thx  :unsure:

 

Oh and I found this - it details the idea of spontaneous particle annihilation I was talking about in my own ponderings (above in white highlight), as a means of detecting the signature of dark matter - and the man behind the original theory...yep, it's that Mr Sir Penrose again  :D  I'm having another go at one of his books 'cycles of time' I gave it a valliant go about 3 years ago but eventually had to admit defeat after 125 pages or so, hopefully what I have learned since might get me all the way through it this time  :D

i just want to add a bit more 'filler' as we go along about the 2 approaches to quantum gravity.;..

 

string theory has a background in quantum mechanics and it is known as a covariant approach to quantum gravity - i shall be coming to string theory next week but probably the week after as i have things to do next week, I am much more conversant with string theory and thus more confident in my treatment of the approach....

 

quantum loop gravity on the otherhand actually has a background in general relativity - it is known as the canonical approach, what happens is that space time is reformulated by the use of 'spinors' it basically makes general relativity more affable to quantization - discreatization -by making it remarkably similar to these things known as gauge theories. And again I ask - who was responsible for the mathematics of spin networks as they have been subsequently applied to quantum loop gravity - guess who  ;)  yep - mr sir roger penrose AGAIN!!

Right, just before I dash off on a small vacation I would just like to leave you with a pocketful of interesting facts....

 

- if there was no general relativity GPS (sat nav) could not work.

- if there were no quantum science that computer you are playing this game on would be the size of a house and pale in to the shade compared to a commodore 64

- the power in an average laptop would have been more than enough to send man to the moon in 1969

- voyager 1 and 2 became mankinds first interstellar objects last year and are transmitting a signal back which is weaker than the signal from your mobile phone

- there are more atoms in a glass of water than there are glasses of water in the entire oceans of the earth

- there are more combinations of moves in the game of chess than there are atoms in the visible universe

- to fully describe a quantum system would require a fountain pen dipping in to an inkwell the size of the visible universe

- the qubit is the first development towards a fully quantum computer and the estimates of its processing potential are such that with todays most powerful processors it would require a computer the size of planet earth to keep up with a quantum computer the size of a laptop, they estimate they'll have quantum computers up and running within 20 years 

- there would be enough processing power in a quantum computer to simulate your brain processes and everybody elses on the planet together with all the stars planets.........in fact it would be possible to fully simulate the entire universe without any data compression at all

- if they manage to fully simulate an entire universe that would make the odds that we too are living in a simulated universe astronomically likely!!!

 

thx

 

nice holidays  :D

Right Deena, and you know what's cool about all that scientific mumbo jumbo above? It was all SPOKEN into existence maybe 6 - 10 thousand years ago by a GOD who loves us dearly (mankind excepted- in our case He stooped down, grabbed a hunk of dirt, formed man and and breathed the breath of eternal life into him -then took a rib from the first man and made woman). Very simple!

Well god bless you sweetheart, and whatever gives you strength - all the more power to you for it, I guess I myself started reading about all of this mumbo jumbo of which I speak when faced my own dark times and I was looking for something to help me push on without fear, we all find our outlets hopefully we do, and it helps us tremendously as I am sure your faith helps you. My partner is buddhist and I can see how this makes her ever more rich in those fundamental qualities, a buffer for the soul it is indeed - and we made our own special pact too - that I must go to buddah and not back out in to the universe because there's no food in space and we will be able to eat with buddah see... ;)

 

I am not one of those religion hating scientists, and nor do I ever intend getting in to any arguments on the matter - you only have to go on Yahoo science to see the crossfire on that and it is most unfortunate - and I've been involved in enough drama on here for 1 lifetimes worth already, lols.

 

Each to their own field I say - and if there is no further interest in this topic of which I like to write about then of course, it will fade out and I will continue with my interests elsewhere within that community, it was something I wanted to push on the table here because science does itself no favors sometimes making itself so unavailable to the layman and I believe it can be explained in simple enough terms to garner the interest of the majority of us who are not that bright :) 

 

Respect to you.

Thank you Deena for that polite/respectful reply. The purpose was not to start a debate or have arguments on who's right or wrong etc.I just wanted to express my creation opinion and maybe it'll get people thinking (I love tweaking people's minds ask my wife).Anyway Deena continue with your scientific monologue. Oh one more thing if anyone out there would like to read more about creation science go to icr.org (Institute for Creation Research). Real scientists there who believe that the universe and everything in it was created. If you want to talk more (not debate) about this our anything else you can friend me and we can go from there. So again back to you Deena.

And there you go Pappy and deena prove happy outcomes are possible here :D

 

I will take a look at those pages you point to, and I was going to get to the work of a guy called Maldecena at some point, it is about holography and some of the math(s) that has been developed from it actually goes some way to tackling some of the brick-wall problems with string theory and is among some of my favorite content for sure - the matrix eat ur heart out!! - science does not rule out creationism, if it did then the quantum world has since shown things were not so deterministic as was once thought in the 18th and 19th centuries and indeed creationism cannot be dispelled, it can even be taken scientifically as you point out, things such as the value of the cosmological constant remain thorny issues among scientists, the notion of a multiverse combined with the principle of fecundity seems a most powerful argument against intelligent design, but until one or the other (or even both - imagine that, the creation of a multiverse cannot be discredited hey  :lol: ) then both remain options - it's just nice to know I was born in these times that we could even contemplate such things.

Ahhhhh, my brain started hurting after reading your first post D.  Happens every time I cogitate on our existence and the universe.  All I know is that our  reality is based on what we as a species needed/need to survive.  Try, just try  to imagine the world of any animal or insect and the world that is their  reality.  Specialized design and senses for sight, sound, vibrations, the earth's magnetic field, and probably many more we'll never know of.

 

I prefer to simply think of the entire universe as nothing more then a miniscule drop of falling water in some other universe...just as there are universes in every rain drop that falls to earth.  BTW, what can you see further  with...the most powerful telescope or the most powerful microscope?  (Purely rhetorical).
