What I like about physics is its basic definition no matter how the terms differ from one topic or chapter to another they all go back to that basic definition of “push or pull” say; on or off in electric switch or 1 or 0 in binary on electronics ( or so on….touch or press on screen of smart devices or keyboard of screen into the electricity stored with all other memory or motherboard or all).

The question is our thinking of subjectivity or makes this push or pull? Does it all ways have to done by something with or matter like a human or object? Or other Forces can do this in independently with no help of mass/matter?
When we think of or talk about space, are we referring it as where the density of particles is loose or are we referring it more thing almost like a vacuum? If i am not wrong the difference between solid/liquid and gas is the reaction which is finally the density within the particles ( how compressed they are)…. the electron proton or nucleus reacted with the same ones of the same element or others in different elements… are the known elements present other galaxies or different ones or in which form because if there are no particles we should vacuum not space?

Thank you all WS-U/F, All members -living and non-living (presenters, partipants,recorders, transmitters, hosters including the earth, its materials and transmitters inlccuding the internet, browsers, webs and my Device).
I really like this site as I have taken some courses in few days in videos which i is the third educational presentation i like the most as person, along with practicality and metal/emotional thinking with all its analysis and fairness of through.
I would few more basic questions but not here as they may require multidisciplinary team in professions, cultures and backgrounds and much more….
I am trying way to write the presenters or website team (world science U and world science festival -WSU/F)…

FORCE+MATTER or FORCE+MASS AS ONE MIGHT CALL…… with all those mass and weight difference at atom or galary/Univers level….. any thing we know.. including life

I am not talking about the force we learned in school that was part of the engergy= force+ work from right left reading probably.

Anyhow thanks.
