Question

what is space actually?

Answer 1

hi freind
here is ur answer

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.


hope it will clear your concept.

Answer 2

Answer:

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four- dimensional continuum known as spacetime.
