PhysicsWeb. I'm not sure I understand it well, but the scientific discussion seems to be on whether there are hidden variables in the universe that make reality exist in a consistent way, even when nobody's looking at it. And whether the universe is basically local or non-local. "Local" would mean that one can separate events completely from each other, so that they can't instantenously influence other events.
Markus Aspelmeyer, Anton Zeilinger and colleagues from the University of Vienna, however, have now shown that realism is more of a problem than locality in the quantum world. They devised an experiment that violates a different inequality proposed by physicist Anthony Leggett in 2003 that relies only on realism, and relaxes the reliance on locality. To do this, rather than taking measurements along just one plane of polarization, the Austrian team took measurements in additional, perpendicular planes to check for elliptical polarization.

They found that, just as in the realizations of Bell's thought experiment, Leggett's inequality is violated – thus stressing the quantum-mechanical assertion that reality does not exist when we're not observing it. "Our study shows that 'just' giving up the concept of locality would not be enough to obtain a more complete description of quantum mechanics," Aspelmeyer told Physics Web. "You would also have to give up certain intuitive features of realism."
Sounds like they're saying that experiements really do confirm that reality isn't real unless somebody's looking at it, and that everything is instantanously connected with everything else, so you can't isolate any piece of anything and claim that it has a real existence, separate from everything else, and seperate from who's observing it. I sort of figured as much, but it sounds good if they're rocking the boat a bit by proving it.

Science and spirituality converge.....google this- Souls of Distortion Awakening........want more? Dare to get past the face and delve to the depths of this website, you wont regret it: askrealjesus.com - ignore the christian connotation - incredible scientific treatsies there....."There is more in Heaven and Earth, Horatio than can be imagined in the minds of men." -Willian Shakespeare  


17 May 2007 @ 19:41 by Joze Vilfan @193.77.20.97 : How we perceive reality
I wouldn't say that reality does not exist without us (the observers), but the point is that reality is infinite and "smoothly" interconnected. And only we, the humans, establish the individuality of objects, we define the boundaries of objects, beings, phenomena. It is through our interference with(and consequently understanding of) the environment that things get defined, isolated, and structures postulated. The infinite world is then broken into meaningufl "chunks", like "mother", "father", "company" etc. In fact, each of these "chunks" is in itself an infinity of states in which people interact among themselves and with the physical environment.

... when we're not here to observe it??... I guess we wont find the answer by observation.

Whuhhh??!?!

Lived Neo-Tech Physics directly under DR. Wallace himself but nice try my friend unfortunatley you can not be the best at everything right? Cause I AM! I am GOD son  


24 Aug 2007 @ 03:04 by ALEJO F. ESTEPA, ATTORNEY @203.76.221.158 : REALITY TO THE SENSES ONLY BUT NOT REAL
there are many things that we think are real, real only to the five senses but not reality as related to what it or they really are. For example, we touch and feel and see a piece of wood and conclude that it is solid,l it is real But in the first place, the wood is NOT SOLID, AS OTHER OBJECTS THAT WE GENERALLY CONSIDER OR DEEM AS SOLIDS.EVEN THE VERY COMPOUNDS AND BASIC ELEMENTS IT IS MADE OF SHOWS SPACES AMONG SOLIDS, MORE SPECIALLY AMONG LIQUIDS AND MOST ESPECIALLY AMONG GASES. EVEN AMONG THE ELECTRONS AND PROTONS THERE ARE WIDE SPACES, EMPTY SPACES THAT SHOWS THAT THE OBJECT IS NOT SOLID. SO IS OUR CONCEPT OF REALITY - REAL BECAUSE WE SENSE IT WITH OUR FIVE SENSES. BUT WHAT ABOUT THOSE THAT OUR FIVE SENSES DO NOT , REPEAT DO NOT, SENSE? LIKE THE DUAL UNIVERSE WE LIVE IN OR THE OTHER BEINGS LIVING WITH US ON PLANET EARTH BUT DO NO SEE, FEEL, TOUCH OR SMELL - BECAUSE THEY EXIST AND ARE REAL IN A DIFFERENT DIMENSION... WE ARE 3.5 TO 4 DIMENSION, THEY ARE FIVE TO NINE DIMENSIONS. HOW I HOPE WE HAVE MORE TIME AND SPACE TO TALK ABOUT THESE DIMENSIONS. THANK YOU, FLEMING FUNCH.

Very much true ... the reality doesn't exsist if not observed
"Observer Creates The Reality Simply By Observing"
Quantum Physics Rocks :)

giti می‌گه:اما ازطرف دیگر باید گفت که ژیژک ، بعکس نوام چامسکی ، علیه دو کشور جداگانه برای یهودیان و فلسطینی هاست و از یک کشور برای همه در فلسطین پشتیبانی می کند که امروز تقریبا همگی به این راه حل رسیده اند و دو کشور را نه تنها عملی نمی دانند بلکه عقلانی هم نمی بینند. این نظر را دولت ایران همیشه تبلیغ کرده است. ژیژک می گوید.In the ABC religion and ectihs section, Slavoj Zizek speaks about the fictitious two state solution, annunciating that which many of us already know: ‘If there is a lesson to be learned from the protracted negotiations, it is that the greatest obstacle to peace is what is offered as the realistic solution – the creation of two separate states.’Zizek goes on to say:What both sides exclude as an impossible dream is the simplest and most obvious solution: a bi-national secular state, comprising all of Israel plus the occupied territories and Gaza. Many will dismiss this as a utopian dream, disqualified by the history of hatred and violence.Zizek seems oblivious to Nutanyahoo’s plans to assimilate parts of the West Bank adjacent to Jordan in the fertile Jordan Valley for Israeli military purposes.
