DIFFERENCE BETWEEN SPACE AND UNIVERSE
DIFFERENCE BETWEEN SPACE AND UNIVERSE
So, here we go.👇👇👇👇
Basically, when we talk about the universe and the space we start thinking about the stars, galaxies , black Hole, Wormholes, asteroids etc. And most of the peoples think space and universe are same thing.
But the reality something different from this.
So, what is the difference between the universe and space?
Now , let's understand these both term one by one.
SPACE :-
Space is nothing but the three dimensional expanse.
Or in other words, it's infinite three dimensional extends in with all the matter and energy exist.
So, whatever matter or energy is in existence , that exist in Infinite expanse of length, width and height or space.
So, where is space?
Basically, space is everywhere.
It is all around you. Even it is inside you. Not only inside you but in atoms also.
Basically, that atom itself exist in space.
Isn't it cool? Just think space is all around you.
Great!!!
Remember :- When we talk about space, we are not included time in it!!
If we say SPACE , then it means only three dimensional expanse. Nothing else!
We are not including time here.
If we go to include time here then, it's not space . But now this is called as space time.
SPACE-TIME :- Space-time is fuse model of three dimensional space (x-axis, y-axis and z-axis) and time.
And remember that space cannot exist without time and time cannot exist without space.
I will make a blog specifically on time :)
Stay tuned!!!
Now, what is universe?
UNIVERSE :-
Basically, universe can be considered as the entire space-time together with its contents.
So, if we talk about universe , that means nothing is left. All thing are included in it (mass , energy and space-time).
So, is there any type of universe ?
Yes ! Yes! Yes!
It is of two types :-
1). Observable universe.
2). Unobservable universe.
1) OBSERVABLE UNIVERSE :- The part of the universe that can be observed or can detect by any instrument eg. Hubble space telescope is called observable universe.
The observable universe has the diameter of 93 billions light year that contain numerous galaxies, stars, planets etc.
Till 1922, it was believed that observable universe is of 100,000 light years but after 2012 we observed 93 billions of light years.
Woah!! Really huge!!
2) . UNOBSERVABLE UNIVERSE :- The part of universe which is unobserved by us is called unobservable universe.
We don't have idea how huge it is! Is it Infinite or limited!
We don't know anything about it.
But in future we can observe it too as technology is increasing.
MULTI-UNIVERSE:-
It is believe that our universe is not alone. There are infinite number of universe and these are called multiuniverse.
Maybe there are Infinite copies of us.
Maybe some of them shows different laws of physics.
Maybe they don't exist.
We can't say confidentaly that it really exist.
In our own universe, can there be Infinite copies of us?
Yeah , if our universe is Infinite then, sure there will be infinite copies of us. But why?
We know the continuous consecutive Infinity series has all possiblities. So, if our universe is Infinite then, there will be continuous repeatation of consecutive atoms that can make ours copies.
But we don't know it is Infinite or limited .
So, generally we can only predict.
Stay tuned!!
And be ready for my next blog!
