The Universe means Existence and that means ‘Something’. In the present-day universe ‘Something’ can be seen as quadrillions of objects,structures and mediums over the vast expanse;Non-existence or ‘Nothing’ being the absence of something.
See more on Existence
Objects are aggregations of ‘the stuff’ (e.g.planets,stars) whereas mediums mean ‘the stuff’ in non-aggregated form(emitted,exploded material).The Objects and structures are built using ‘n’ number of ideas,the permutations and combinations of those ideas,thereby making universe an existence of diverse variety of entities ; and more thrilling aspect is that this amazingly vast and un-limitedly diverse universe seems to have been built using an incomparably few number of ideas & principles
What can be witnessed throughout the universe is ‘Constant Change’ (Dynamism) through the events of Construction(creations happen constantly),Modification of constructed(constant evolution of the created ones),Destruction of constructed or modified ; all of which happen because of the ‘Constant Change in the Particle(s) Position’ (CCPP) in the stuff that constitutes pre-construction material, constructed ones,constantly modified ones.
CCPP means Movement of the particle or a group of particles , CCPP which is the cause of constant change in universe, is the one word answer for everything of this universe and the universe itself ! The reason why constant change can be witnessed throughout the universe is because Constant change is the mantra and purpose of ‘the stuff’ and it’s avatar-the universe,it goes on creating various ideas(inventions),also causes permutations & combinations of those ideas resulting in newer ideas and thereby causing and propagating the diversity.
Time is a feature of this Universe ; Past, Present,Future.Whether time has eternity tagged to it or not is yet to be explored.Constant change gives meaning and value to ‘time’ !
The Knowledge Sphere which is the information pool of this universe, keeps growing and evolving with the constantly changing universe.The knowledge sphere is a living creature’s understanding of the universe.
The present-day universe is simply a mesmerizing museum of lots of ideas(those preserved ones among the pool of inventions that happened),permutations and combinations of those ideas
an ‘everything-is-possible’ plus ‘constantly working’ laboratory for further invention of more and more ideas,for creating more mixtures of such invented ones,thereby propagating the created diversity…that’s it !!
