What is there below and above space?

well we know that if we go straight we will meet planets,etc.but if we go down into space what will we find?and also what will we find up?

In space, there is no absolute notion of "above" or "below", all the directions are pretty much the same. Only standing on a planet or a star do you have this notion due to its gravity. So if you stand on earth and you go down, first you will reach the earth core, then the opposite surface of the earth then space again!

But did you mean going to the smaller scales (become smaller and smaller)? First, you would encounter dust in the air, then viruses and bacteria, then air molecules, then protons, neutrons, electrons, then quarks and leptons. It's not known yet below that scale what we would find.

Doesn't matter which direction you go, you will encounter other galaxies, asteroids, planets, the whole shebang.

Dark Matter.

an unsolved puzzle yet

i think stars and then sky.... blank space and then stars and again blank space..... sky.......stars......space full of nothing......stars.......galaxies.......... cluster.......stars......planets...galax... space............planets........planets again.......sky and galaxies....planets...... in other words: endless amount of thing and darkness larger then anyone can ever imagine!!??

up, or down, or left or right, are all relative terms.
your left can be someone else's right ad vice versa.
up and down matters when gravity acts.
in space we enoucnter zero gravity.
so all the directions are much the same-- null and void.
so, if u are asked to go up r down, it has to be relative, and the refrence here is given in terms of other sstars and plante that appear failr static when viewed from our space.
and as the answer always was, is and will be,
the space is much the same.
there is an equal probability of u coming to another planet, either down, or up or left right center.

There is space everywhere without any end,no matter in which direction you go.Nevertheless, direction is with respect to earth.When you go outside in space ,there is no direction either.

Whatever made you think space was 2 dimensional?

Read some books on cosmology.

i have not gone into space to answer your question. ask any astronomer if he can.

there's no end of space..its vast,unimaginable nd ecstasic.,complex,deep

only space and air molecules or some chemical or physical reaction take place

in space u can fly can't walk
