There has been lot of discussion in recent decades about “state of nothingness”. Philosophers , scientists , teachers , scholars and many other groups have been discussing about was there “nothing” before this universe.  Most of the discussions goes on understanding of nothing itself .Can there exists absolute nothing or what is nothing itself is yet to be locked into scientific discoveries.

This blog post is inspired from Lawrence Krauss‘s discussions and thinking about  nothing.  This blog post is not about theoretical physics etc and is all about my honest opinion and  my thoughts on “nothingness“.

Lets start with very simple state of nothing , and for that I put a statement : “There is nothing in my pocket.” This is very relative statement and for me it means there is absence of things which are commonly kept and looked upon in the pocket. But there exists air inside , so definitely there is not nothing because air is something. As long as we find something we can not say it’s nothing.

Lets create vacuum in a iron cubical box by removing air. Now can you say there is nothing in the box ?   Electromagnetic waves can travel trough vacuum and on earth we have so many electromagnetic things going on (mobile , radio , television signals and what not are all electromagnetic)  and so there exists something in the box. Also because we can’t realistically make 100% vacuum so there will always be something in out iron cubical box on earth.

Now let’s go to deep space and imagine 1m cubical area out there. Again assume vacuum is out there. Is there nothing ?  What about light from stars, you will always have some light (low/high intensity) out there coming from some or other star.

We can go further deeper and we will see Gravity,Time, Magnetic force etc out there.  Also we can call space itself a something. Now if space itself is something then it’s highly difficult to imagine things which can exists without space. Only your thoughts then can exists without taking space(and even someone can say thoughts take space in brain).

It seems to be inconclusive or branching discussion and so it will be good to first arrive at a point or definition of few important things out here and then again talk if “nothing” can exists.

Two of such things are “exists” and “a thing”. What are all things that we can say they fit into category of  “a thing”. What is the criteria on which we can call if it “exists” ?

So in conclusion , to find out if  “nothing exists” we need to know what do we actually mean by “something exists”?  If we answer second question we may be able to categories  what is “nothing”  and if it exists or not.

Please watch this space for further discussion on this topic on my blogpost.

This “Time” series is my honest attempt to know what do we mean by “Time”. What is the nature of it. It is offcourse not necessary ( and is not ) to match with what someone says.  Ans so I am saying it as my honest attempt.

In previous blog (link) we discussed if Time is purely just a discovery by humans, i.e. have we discovered it ? To be able to discover something we need source for that thing , medium by which it travels (or stays) and our senses to detect it. For time we don’t have any of those. There is no source that creates time, time does not have medium , and we don’t have any sensor which can detect time.

We discussed that we have memories of something happened to us and our consciousness tells that we have memory. e.g. we were very little conscious when we were a year old. We don’t recall any of the things happened to us at that time. We individual can not surely tell if we were one year old for sure in past (we logically think that to become 30 yrs old we must have been 1 year old and that’s it. There is no real proof that one himself can generate that he was one year old.  Your parent can show you old photos ,videos etc but it’s not you , it’s them.)

So consciousness is helpful to let one confidently differentiate between past and present.

Let’s go to other branch to see if Time is our invention.

Invention is something lies in our creation category. e.g. GOD is our invention. We have not discovered GOD , instead we have created it for our own sake.

Is Time like a GOD , that we created for own sake ? Both of them does not have source of creation , and we either don’t have any sensor to detect it’s presence.

Whether or not GOD is an invention is very debatable and so let’s not fit time into invention category just because my personal opinion about GOD being an invention. Another example of invention would be let’s say a Chair. It’s an instrument to sit and take rest(it’s a physical instrument). Another example would be mathematics. It is our invention (virtual). It is a thought or collection of various logical thoughts.

Is Time just a thought or is it a external independent thing ? We will discuss more in upcoming blogs.

Thanks for taking time to visit Purity from your busy life. I hope you had a different thought today.

ONE of the main reasons why human could conquer this animal planet is his ability to “Study”. In this blog I am posting my understanding and opinions about “changed meaning of word Study in current times”. This blog is based on my observation of the same in primary schools  , colleges and universities.

To me meaning of study is  to observe ,  and for one to become master in particular area he must practice.  Observation along with practice can make one a Professional.

Today the meaning of study has completely changed and it has become “to read“. And for one to become master he is “remembering”  what he has read.  So today’s professionals are “readers who could remember”.

Well , surely not everyone fits into above category but you will agree most of them though fits in. Immediate question would be why are we going on this path if this is not right way. How one can study rightly. Is reading only way left to study now as Newton, Darwin, Einstein , Faraday , Hawking already did the “observation” part and nothing is left for us to study? Is reading and remembering giving us the success (money) and that why we are on that path ? Is today’s competition very high that one does not have time to observe and grasp, and if one does  will he not succeed ?

To know all these , keep visiting Purity for my upcoming blogs.

Thanks for taking a moment in your busy life to visit Purity. Hope you have a different thought to take with you today.

I am keeping the blog length short from now onward as some of my readers suggested, they are too busy and if the page size is more then it’s not effective.

I am sure one day my daughter is going ask me “why 1 plus 1 is 2?” and I am going to go nuts to answer this. This very thought generated in me a basic question “What is the limit to ask why , meaning till what extent one can ask why ?”

Let’s try to answer above question of  why 1+1 is 2 itself (explanation is not to my daughter , she wont understand it as of now).

First hand answer  : “because one apple and one apple makes two apples”.

Question: But both apples may not be same, will still it make 2 apples ? why ?

Answer: I think size wont matter while counting.

Question : If I cut one apple into two pieces, then along with second apple , how many apples I will have?

Answer: “Well” , umm.. in this case apples are 2 but count is 3 . (Ah!!)

Question : That means , size does matter.

Answer : Ok, Let me explain in you by another way.  2is a number and 1 is a number. 2 is away from 1 by 1. (:O), and thats why when we add 1 with 1 it becomes 2.

Question: Why 2 is away from 1 by 1  ?

Answer : We have number line which makes the two numbers separated from each other with some logical distance. For equal distance intervals we name it by number. e.g. 1 , 2 ,3 ,4,5 are equidistant intervals.

Question: Why we have number line ?

Answer : That’s our base of mathematics.

Question : Why we need base to a subject ?

Answer  :  This is common practice to make a base i.e. foundation and then create the whole system. And that works , rather it has worked in past for many such systems.

Question : why common practice is trusted to a level to make a base and then system?

Answer: Because it works.

Question : Why something has to work to make it a common practice?

Answer : Because if it does not work then we can not use it .

And the series goes on….. A point comes in the series where ..

Answer:  “there is a GOD who created universe, and thats why it is like that.

Question : then who created this GOD?

Answer : GOD does not need creation .

Question: Why he does not need creation ?


Question : Why HE is the GOD???

And it never ends!!!!!

Main idea of this blog is to tell you that every single thing in this universe  , be it logical , physical , virtual ..anything , is questionable and questions are limitless, there is no limit .

It is limitless both ways. You can go solar system, Galaxy, Universe , multiverse etc i.e. outward. And you can go towards atom, electron , boson etc.. i.e. inward.

Now question is does human has limit to know the limitless nature?

And that’s what is called Science , an approach to study limitless nature and break the today’s known boundary to tomorrow’s unknown secrets.

Thanks for visiting Purity, hope you had a different thought for a moment in your busy life!


Time , for me , is one of many concepts which we have taken granted by us in our understanding. We think that “time is passing or running each and every clock tick and we dont go deep to know more about it. And so this blog is to question the basics of it and give a small attempt to go deeper in our understanding of “Time”.

All of the things that we know are either we have invented (created) them or we have discovered(found/observed) them. So in that sense is the “Time”  just an observation(discovery) or an human’s own creation (Invention) ?

May be to answer this let’s first see some other things e.g. sound, is sound observation or creation ? Well , you can say it’s a human sensory observation of pressure waves for which we gave a word “sound” . Other languages has different words for this observation. Lets go further , did sound exist before humans ? Well yes, sea waves make sound when landed on rock or simply pool of water splashes on other water pool or any object , the friction between them makes sound waves. But importantly we need some medium to have sound. No medium no sound. On earth we have atmosphere (air) so we have sound here but not in space. e.g. on moon, there is no sound there. So we can say that sound source along with medium makes sound which we observe ear.

So to summarize, sound is an observation/discovery by sensory living beings in the presence of sound transferring medium. And we can say we need  Source ,Medium and Sensor to surely know existence of sound.

Can we generalize this above statement for every observation or discovery of human being and say  : “Every discovery or observation made by human begin needs Source (or the thing itself) , medium (to reach our sensors) and sensor (e.g. eye ,ear,touch etc)”.

With this new framework can we judge if “time” is our observation/discovery ?

First of all do we have source for “Time” ?  No, not that is known today. There is no known things which can create time.

Can time be sensed by us ? How?  Eye , skin, tongue , ear, nose are not for sensing time.

Does time require medium to reach out to humans?   As there is no source we cant think of medium it uses.  But at experience level let’s hear some general arguments which brings some logical points to show existence of time. (Contradiction to each logical point is explained after each point.)

One can say we observe time by notion of observing something changing and we can say it was past and this is present. ==> But if we remove eye and ear and deactivate your touch sensor and you can’t smell and the tongue is removed,  does that mean “time” does not exists for that person ?  He still ages and for other person’s how are seeing him growing , time exists.

We see clock ticking and that may show time is passing. ==> Well then my argument would be I have stopped clock, does that mean time is frozen ?

We age , we die. This may show time is passing. ==> But what happens in space- there is nothing out there. Nothing dies and noting ages there , so no time there ? What is your aging and dying has to do with time ?Is it just the changes we see in living being makes existence of time ? Or it’s existence is based on location, i.e. there is time on earth as there are living beings v/s there is no time on Mars as there are no beings there out ?

We have past memories and future thoughts , that may represent there is time. ==> Isn’t  it your consciousness which helps you to work on memory. So may be here your consciousness has something to do with past and present things.

So far “time” is not direct sensory observation but we see some relation with consciousness.

In the next part of this series i.e. “Time-Part 2” we will together find more about time.

Thanks for visiting Purity and I hope you have some nice thoughts to take with you today. Keep visiting.


In this blog, I am trying to capture some nice thoughts that I came across and some from my own philosophy.

Here goes the list  :

The greatest challenge to any thinker is stating the problem in a way that will allow a solution


Tell me, and I will forget.  Show me, and I may remember.  Involve me, and I will understand.


Be the change you want to see in the world!


Chain is as strong as it’s weakest link.


If Death is guaranteed , birth also could be!  Reincarnation is logical.


Pain is certain, suffering is optional .

Hello, world!

Hello, I am Dhananjay and it is my first “Hello, world!” blog out here.

“Hello world” is common paradigm used in software programming arena which may mean various things to various people but commonly it is :

i) To experience , test  and get confidence of the software language by writing a code which prints “Hello, world!” on output screen.  Almost all software language has some output screen to display results and so this is widely used paradigm.

ii) To represent first program of programmer.

And so I am calling this as my “Hello world!” blog.

Thanks for visiting !
