Is Vaccum Space Really Vaccum ? : Introduction to Quantum vaccum state

Space in physics is a all pervading reality,space permeates the entire Universe.   All particles,all bodies ,animate or inanimate bodies all within the space and everything we can imagine is within this fabric of space . 

But a  question arises in the minds of scientists that " Is the space really empty ?"

" Is vaccum space  really empty ?" 

So in order to answer this question physicists modeled a theory which is called as " Quantum vacuum state " .                           This theory was proposed by physics working on the model of  " Q .E .D"(Quantum  Electro Dynamics )  . 

The model of " Quantum vaccum state " was proposed during 1930s and during 1940s .

The notion of " Quantum vaccum " was suggested by Scientist Warner Heisenberg who stated that  the general idea about space being empty is not true ,because there is nothing like " absolute vaccum"(empty space). Rather in a localised point in a region of space ,we can trace  sudden or rapid changes in the energy.                                          According to Proposal of Heisenberg  ,the notion of empty space is falsifiable as according to him there is constant - sudden changes in the vaccum state of existence and these small scale changes in a vaccum state creates " Quantum Fluctuations" .

     Quantum physicist Werner Heisenberg 


These " Quantum Fluctuations" are nothing but rapid changes in the energy in any field of space ,which creates " Quantum Foam" ,this quantum foam is nothing but small scale fluctuations in the energy in a field in space time . This quantum fluctuations are so minute and subtle that they constant created pairs of matter and antimatter which constantly annihilates each other at quantum level and physicsts call these highly unstable particles which comes from this quantum fluctuations in vaccum  or in a "  zero point energy field" as " Virtual particles " . The term " zero point field " invoked the idea about a field of vaccum which is in a very low state of energy level which in small scales creates fluctuations ,thus giving rise to these virtual particles .

" Derek Leinweber" a physicst and professor of " Adelaide University" using a super computer simulated an simulation of the phenomena of " quantum fluctuations" in a region of space .

  Derek Leinweber, professor of Adelaide           University, researcher of Quantum field           theory, who simulated the "quantum               fluctuations " using super computer

So , we can say that Vaccum is not empty rather vaccum is full of small scaled random fluctuations of electromagnetic and other force fields ,which creates virtual particles and particles and manifest reality as we know it from its zero point energy field.

Energy and Consciousness : Fundamental reality of Universe

 Energy in physics described as "the capacity of a system for doing work ". This is the simplest and vaguest definition of energy in classical physics . This definition is right yet  unable to define energy in its true form  because the definition says " the capacity for doing work " hence as long there will be capacity in a body or in a system for doing work ,the energy can be expressed mathematically interms of both potential and kinetic form of energy.  Hence  in classical physics ,energy is defined  as long there is  work done which is measurable in quantity.                 Cosmic Energy of Universe   Energy can only be defined in terms of classical physics if there is relativity interms of motion and rest . If energy stays at rest with respect to its surrounding objects i.e energy stays  in inactive state it's called potential energy and when potential energy manifests as  motion with respect to its relative objects it's called kinetic energy .

Swami Vivekananda about " Brahmacharya" and sexual transmutation

Image
Brahmacharya is an ancient Hindu practice which first introduced by Veda Vyasa  in chapter 234 of shanti parva in the Mahabharata praises Brahmacharya as an important stage of life necessary for learning ,then adds Grihastha stage as the root of society and important to an individual's success. Brahmacharya in Hinduism literally means "conduct consistent with Brahman" or "on the path of Brahman". Historically brahmacharya referred to a stage of life (asrama)within Vedic Ashram system . Ancient Hindu culture divided the human life span into four stages :brahmacharya ,Grihastha ,Vanaprastha and sanyasa . But not only in Hinduism but this holy practice also belong to Buddhism  and Jainism as well.  now lets talk about this in detail .  "Brahmacharya" this word consists two words ,which are  "Brahma" and "Charya" ."Brahma" means ones own self , ultimate unchanging reality ,absolute consciousness ,much discussed in Upanishads .

Charvaka Epistemology: Ancient Indian Philosophy On " Materialism"And it's Drawbacks

Image
            Brihaspati ( founder of charvaka                      philosophy) talking with  a king   Charvaka is a crude , rudimentary form of philosophy. The charvaka philosophy mostly based on the notion of perception and experience being the only source of veridical knowledge. Charvakas believe that  anything which beyond experience is not acceptable as a source of knowledge. They refutes metaphysical aspects of  existence and refutes the presence of Brahman ( God) and Aatman( essence of One's individual soul).  They only relie upon the five senses,and reality to them is just a projection of those senses. Hence, in a way  Charvakas are Empiricists  of ancient school of Philosophy. This Charvaka philosophy originated in India in 600 BCE ,though the name of the founder of this philosophy is disputable. Some say ,the founder is Brihaspati who has  also written Brihaspati Sutra but some say founder was philosopher charvaka himself .Now let's talk about the philosophical aspects
