what is space?

Answer 1

most people here seem to be confusing space and vacuum.
Space isn't really an entity in the physical sense. It' s more like a geometrical abstraction, that supplies us with means to do describe relative positions of bodies to each other.
Space in other words is more a product of human thought than anything else.
And so is time, by the way

Answer 2

Space is not a separate entity. The universe is space-time. Time and space are inseparable. When the space surrounding a massive object (such as a star or planet) is warped or curved by gravity, so is time. Space-time is the environment created at the big bang in which all events happen. Time is measured between events and space is measured between objects, however, in reality both time and space are measured together for all events and objects. The difference between what you would measure between two objects that are a few feet apart and the real measurement due to space-time dilation is so small it is mostly ignored. At speeds approaching that of light the difference becomes much larger and must be considered in calculations.

Answer 3

In astronomy
Space refers collectively to the relatively empty parts of the universe. Any area outside the atmospheres of any celestial body can be considered 'space'. Although space is certainly spacious, it is not always empty, but can be filled with matter — say a tenuous plasma. In particular, the boundary between space and Earth's atmosphere is conventionally set at the Karman line.

Answer 4

Space has been an interest for philosophers and scientists for much of human history. The term is used somewhat differently in different fields of study, hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. Disagreement also exists on whether space itself can be measured or is part of the measuring system. (See Space in philosophy.) Many fields use an operational definition in which the units of measurement are defined, but not space itself.

Answer 5

You could say that Space is a vast expanse of nothingness. When you consider how much space is actually out there and how much physical material there is, Space is pretty empty.

Space can be determined as 'The region of expanse beyond Earth's atmosphere'.

Answer 6

space has two meaning one is the distance which is empty between two or more objects.another is that it is a part of universe.eg-internet is universe and web-sites are space.

Answer 7

1.
There are an independent space and independent time:
We notice it on our planet - Earth.
It is a fhree - dimensional space.
2.
There is simultaneous union of space and time:
It is negative four-dimensional (Minkowski) space.
Herman Minkowski :
“ Henceforth, space by itself, and time by itself,
are doomed to fade away into mere shadows,
and only a kind of union of the two will preserve an independent reality.”
Question.
What is the “a kind of union of the two “?
The answer.
It is Vacuum. T=0K.

Answer 8

It is nothing, still allows UV rays and radio signals and also allows heavenly bodies to tour in orbits or fall/shoot depending where you are and finally the key > < to use this for filling up space in yahoo answers.

Answer 9

Space is a place where gravitational force is ab scent.

Answer 10

i guess space is space i dont know how else to put it
