What is Space and time?

in order to understand it you will have to understand what is space and what is time? separately so let's see what is this?
whenever someone says "space" you starts thinking about stars, planets, asteroids, galaxies. But you are wrong
space means whole universe except time. Space contains every bit of matter and energy that has ever existed, and yet most parts of it are utterly empty but not absolutely empty an empty space also contains quantum particles. when we talk about deep space then you should think about stars planets and like that, we usually mean the vast stretches of empty area between planets.when time is combined with space they form a continum called space time. space and time are interconnected. both of them is not independent. without time space can not exist and without space time can not exist. Einstein's theory of special relativity created this fundamental link betweenspace and time. The universe can be viewed as having three space dimensions — up/down, left/right, or length, breadth height, depth — and one timedimension. This 4-d space is referred to as the space-time continuum.
spacetime refers to whatever external reality underlies our collective experiences of the space between things and time between events.
My definition of space is
The space is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light.
now what is time ?
Time is without doubt an extraordinarily complicated topic in physics, and there are people who think that it does no longer simply exist.even I also think that it doesn't exist. it is simply a concept produced by humans. One counter or normal arguement whatever you say,physicists used to do is that Einstein proved that the whole thing is relative, and time is not absolute neither space is absolute even rest is also not absolute, so time is beside the point. Einstein "Time is simply an illusion."or the distinction between past present and future is just a stubbornly persistent illusion. Time is definitely relative, and flexible and, in keeping with Albert Einstein himself, "the dividing line between prior, present, and future is an phantasm". is that this relatively actual? Is time just a figment of our creativeness or imagination and the answer my freind is yes.
Among scientists there is not any actual doubt that time does rather, truly exist. in fact for me time has no seperate existence from events and existence from my point of view.
It's just an emergent phenomenon. Physicists are simply divided just a little on what causes this existence, and what it means to claim that it exists. Certainly, this question borders of the realm of metaphysics and ontology as much because it does on the strictly empirical questions about time that physics is good-prepared to handle.
The most original clarification is that in the very far-off past, the universe had a excessive degree of order. For the reason that of this "boundary ," the common laws are such that the entropy is consistently increasing and it never decreases.
Time doesn't exist at all if memory doesn't exist . memory is what produced the concept of time I mean time and psychology are interconnected and so on. without memory we will no longer able to remember the chronological order of events and which will lead to confusion between past present and future.for the memory we need space so I can conclude that space time =space memory. so how is my idea. those people who know little bit thinks that time travel is possible. U imply time is journey is possible or no longer. I feel it is possible as good as now not it is viable considering that time dilation accur however i can say that it a ccurs due to yet another phenomenon which effects the best way of measurement of clocks. By the use of this form of definition, time can not via run backwards. The put off point proper here is that point will not be an independent bodily style you could reverse the exceptional manner you might a particle's motion, alternatively it's stylish upon your definition.In a similar fashion, when you outline time for the reason that the 'arrow of time' evident inside the continuous expand in entropy in a closed process time can not be run backwards. This is in view that the second regulation of thermodynamics dictates that in a closed method, entropy is always growing. If, as to your question, you 'curb the entropy of the procedure' you probably normally growing entropy in a greater approach than the one under consideration.One misconception humans le have is that time us responsibile for causality but not causality is accountable for time.those people who know few about it claims that time travel is possible.
and now what is space time?
space time is 4d concept in which times is taken as a dimension and three dimensions of space and both merged together to form a continuum called space time
hope it helped you
