if your in space can you be upside down,due to no gravity,or is there really no upside down and your always up???

Up and down, in space, on earth, anywhere are established by convention. Up is the direction we all agree to be up. Usually, on earth we choose toward the center of the earth or along the earths gravity gradient to be down and up to be in the opposite direction.
In a place (like most of space) without a single over-powering gravity gradient, you have to develop a different convention. If you watch the space shuttle astronauts, they tend to follow a convetion established by the shuttle builders. Things are arranged, labeled, etc with the assumption of a floor and a ceiling and this provides the up/down convetion.

Well on earth down is the way gravity pulls. So in space down could be the direction of the closest star. (Sun) Just an observation.

Because there is no gravity, there is not an automatic up or down so you can orient yourself up or down as is convenient. Based on descriptions in various works of science fiction and some nonfiction, apparently it can be difficult for some people to switch this orientation.
One of the better descriptions of this appears in Orson Scott Card's "Ender's Game." Another description appears in Vonda McIntyre's "Barbary."

It's all perspective. "Up" is usually the direction opposite an object gravitational pull pulls towards, usually the object is the planet Earth. In a sense, there are many "ups" and "downs" when in space, each one from a different perspective.

I think up and down is just on planets where there is gravity. I guess moons have some gravity also.

There is technically no gravitic sense of up or down. However, there is a galactic north/south axis, so you could say that north is up if you wanted to.

Up and down are relative terms. You have to have a point of reference to compare position. Either that or they are elementary sub-atomic particles:)

There are no (or an infinity of) reference points for "up" and "down" in space, so the concept is meaningless.

its not up or down in space ....since theres no gravity u tend to float .....thats all

Because there is no (or minimal) gravity, there is no up or down.
