Question

What is the difference between Space and Nothingness ?

ans:
As usually we say there is nothing in my pocket or in box.
But is it true?
Because space is present everywhere,
So sentence should be there is space in my pocket or in box.
--
But what is the difference b/w space and nothingness.

Since as we assume about empty boxes there is nothing, but what about gases due to which box maintain it's own shape otherwise it will be distorted due to outside air pressure
That's why box is filled up with gases.

Let's move toward sky where there is neither any or anything.
But is there any place where no any atoms or molecule present. Atoms is huge is size if we compared it with gravitational waves, neutrino and photon.
But there are no any place where waves and space don't exist.
(Since Space contain all this things)
So, we can get a defination about nothingness
In short where space is absent.
In nothingness, light couldn't travel through it even there cannot any type of wave formed since wave also need medium called vacuum.
It's sounds crazy but vacuum has no air that doesn't means it is zero or nothing but in mathematics you could assume it as 0.0000000000000000001 or more fraction of a unit.

Ok let's come to the point
If The big bang was true then it can be helpful to understand about nothingness or for now beyond the boundary of universe there may be nothingness but due to expansion of universe it's converted into space.
But there are lot more research needed to completely understand it.
And we have to find few question as
1. Does, In nothingness Physics work?
~ I think physics don't work here, since there are no particles present in it.

2. Is there energy present or not?
~ I think, if physics don't work here So, definitely Energy don't exist.

3. Where nothingness ends?
~ I think, In this point Universe ends, Rest is energy (infinity)
And this 3rd answer prove that universe is not infinity it has to be an end that's why Physics work here.

Answer 1

Answer:

Nothing: those areas of reality which are empty of matter and can not be defined in spatial and temporal terms (translation: we don't have a clue about where or when they are, and there probably isn't anything there anyway). ...
