Guest guest Posted October 10, 2002 Report Share Posted October 10, 2002 Sri: Srimathe Ramanujaya nama: Dear Devotees, In this post,to the best of my capacity/understanding, I'll try to elucidate what exactly Modern Physics is. Mind you,I'm not a true physicist(fundamental research in unfolding the truth) but come under applied physics! Relativity Theory does not challenge classical physics(Newton's laws of motion and Maxwell's electro-magnetic field laws)but completes it. But quantum theory vindicates(classical physics),defies (i)reality, (ii)locality (iii)causality and (iv)determinism! Modern physics is based on the Copenhagen interpretation. Many believe in physical reality. A physical reality is a model in which any physical phenomena exists independent of the observer. Copenhagen interpretation of the above four views are given below. Reality: If we have to agree with Copenhagen interpretation,then matter doesn't exist untill an onserver looks at it. So basically,"reality" is observer-created. It's the consciousness which creates the reality. Infact,it's taught in Quantum Mechanics course that it's the observer's knowledge that creates the physical result. You can come up with your own examples to refute the argument. Only thing is you need to be cautious and careful in devising suitable examples. Moon is not there when nobody looks at it. When a tree falls in the forest,the noise is not heard/no noise if there is no observer. You can keep on going like this. We have created the universe out of our consciousness(otherwise there is no universe)! Einstein was opposing this view till his last day. This crazy idea of Copenhagen Interpretation(matter doesn't exists untill an observer looks at it) is coming from wave-particle(duality)nature of light. It behaves simultaneously as a wave and particle. If an observer looks at light as a particle,he finds a particle,if he looks at light as a wave,he finds a wave(ghataka sruti). So things are created by the observer's knowledge! Physicists used to crack jokes(plenty of jokes on many stuffs like this!)about light as follows: On Mondays,Wednesdays,fridays,light behaved like particle On Tuesdays,Thursdays,saturdays,it behaved like a wave On Sundays it behaved like both Locality: What this means is that no action on my part can affect what other person sees. Quantum Theory is non-local and violates light barrier. Light barrier is a concept/assumption in Relativity that no material object can travel faster-than-light speed. For example,there is a Enrico shop which sells three types of pizzas(Sicilian,Milanese, Neopolitan)which delivers pizza at your doorstep in 10mnts. Assume that it takes 30 mnts to bake the pizza. This means that the pizza must be ready when I phone to order. But according to QT this is not the case! the shop fellow in no way can know what I'm going to order unless he has some telepathy and knows beforehand what I'm going to order. He doesn't decide to prepare the pizza after i order. So even before ordering,he must have the pizzas ready so that it can be delivered in 10 mnts. This is an example for local-ness. QT says he has telepathy(non-local,information travels faster than light)about what I'm going to order before-hand and keeps the pizza ready. Nobody will believe this! Note:Physicists have concocted a dream of the possible existence of a particle called tachyon(faster-than-light)but so far no experimental evidence has been detected. Causality: QT is non-causal. Causality is a belief stemming from logic. What is logic? A. Make an assumption B. Prove that it leads to a confirmation/contradiction of A and hence C. Conclude that A is true/false Shankara's advaita suffers from fundamental logical flaw. He assumes 1. Brahman,is self-sufficient,perfect,unconditioned and not subject to the subordination of illusion 2. Individuall self(Atma)and Brahman are non-differnt in every manner. 3. If two beings/things which are non-different in every conceivable and perceivable way,then they are same 4. Atman and Brahman are non-different in every conceivable and perceivable way 5. atman and Brahman are one and the same 6. Atman is not currently aware of his true state(non-different from Brahman due to its temporary state of subordination to illusion. If Shankara had stopped with 5,he would have been fine. He was in deep waters b'coz of his last statement which is a contradiction to the first. What does this say? That "MAyA/illusion" is ontologically superior to Brahman(Ramanuja says). Let's come back to QT. Nothing can be created from non-existence(causal). Everything is causally connected. Without a cause there is no effect. But QT says,modern physics doesn't require a cause. The German Physicist(founder of Uncertainty principle and Matrix mechanics) says:"law of causality is no longer applied in QT". In reality(different from quantum reality),either the statement or the negation of the statement is true;only one of the two is true as per classical logic. But in QT,this has to be modified! How? There is a third possibility which is,in strange way,mixture of the two former possibilities. The famous Schroedinger's cat(cat is 67 yrs old and it has got twin daughters!)explains quantum reality and non-causality. Schroedinger is the founder of wave mechanics(he represents the quantum system by a wave). Heisenberg's matrix mechanics(he represents quantum system by a matrix)and wave mechanics are two different approaches of solving the same problem and yielding same results. There are two more approaches(based on copenhagen interpretation)called Dirac's Transformation theory and Feynmann's Path Integrals. All give the same results. I'll briefly explain this "cat" example. There is an ideally isolated system which contains a Geiger counter and placed near a radioactive source that emits gamma rays. the intensity of the rays is adjusted in such a way that in an hour,there is a 50% probability of the Counter to record one count. This counter is connected to a device,which when countoccurs,willshattera flask of deadly poison that would then fill the box where the cat is located. there is a 50% probability that no count will occur leaving the box intact. Experimenter seals the box and leaves the system undisturbed for an hr and at the end of the hr,Schroedinger asks: "what is the quantum mechanical state of the system just immediately before the box is opened and observation is made?" Acc. to QT,cat is half dead and half alive. It's only when the observer opens the box,does he determine the fate of the cat! Determinism; QT is non-deterministic,deals with statistical averages(randomness). This uncertainty(Heisenberg and Bohr's complementarity principle is related to uncertainty)does not lie in our ability to measure but in Nature itself(nature is absurd!). Einstein sharply remarked that:"I can't believe that God plays dice with the universe". He totally disliked the fact that quantum theory implies that reality is observer-created. His thought experiment(subtle many people misunderstand incl his two collaborators)counter to Copenhagen interpretation was: Certain elements of reality exist in the world that are not described by the quantum formalism. most of the westerners are brainwashed by the advaita theory. Lots of germans do research in srivaishnavism. Most of the views of Copenhagen interpretation reflects advaitic views. Einstein,Schroedinger,Dirac,Bell,Bohm were all opposing it staunchly. Only time can answer. Since the road to "better" interpretation of Copenhagen interpretation was closed for almost 4 decades,only in the past decade,physicists started devising sensitive instruments(no where near Einstein's subtle thought experiment)to either prove Einstein's standpoint or refute Copenhagen interpretation. Another important aspect of QT is there is no attribute attached to the reality. Before I eat apple,apple would have had the attribute of sweetness(irrespective of my eating or not). But QT negates it. It's because of my eating(observer's knowledge)that apple has got the attribute. So many fat books have been written on QT and one can go on talking. But i wanted to post it to convey the message "the limitation of science". You know what Einstein did with his Nobel Prize money? half the money went as alimony to his first wife (Einstein was hardly earning anything even to support the family,his wife wasn't happy,she wanted a comfortable life and Einstein couldn't afford,and already they had two sons,first was mentally retarded,the couple separated)and the remaining half for charity. A quote from Einstein(more than a wonderful theoretical physicist,he was a great human being,he was a free spirit,was easily approachable by anyone without barriers): "A human being is part of the whole(universe);a part limited in time and space. He experiences himself,his thoughts and feelings as something separated from the rest- a kind of optical delusion of his consciousness. This delusion is a kind of a prison for us,restricting us to our personal desires and affection for a few person nearest us. Our task must be to free ourselves from this prison by widening our circle of compassion to "embrace" all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely but the striving for such achievement,is in itself, a part of the liberation and a foundation for inner security" Readers may wonder where I'm heading towards. But don't forget that Einstein was a firm believer in God. Karma on one side and Lord's grace on the other side!
