weight = mass x gravitational acceleration
w = mg
If in the outer space, the gravitational acceleration is zero, i.e. g=0, then the weight,
w = m(0) = 0,
Regardless of the mass.

More or less, yes, though not completely. Anything outside the pull of the Earth's gravity is more or less weightless. Weight is the force experienced by a body from the pull of gravity (in this case, the Earth's gravity). In outer space the pull of the Earth's gravity is hardly felt (although it is still there the force is too feeble to have any effect) and everything is more or less weightless. On Earth weight is about the same as the measurement of mass (define as the amount of matter in a body), in outer space the mass of a body remains the same whereas the weight decreases.

he wouldn't be weightless as long as he is not in a lagrangian point... Gravity is EVERYWHERE, except in the few points where several (all of them?) gravity fields cancel each other out...
but you can't really expect to weigh a lot in outer space... (of course it depends on what you consider to be "outerspace", too)
also, just as a matter of interest: planets don't "fall" in space because they are kept in place by centrifugal force. But they're still influenced by the pull of the sun...
And suns don't fall in the center of galaxies for the same reason: they keep moving around the center of the galaxy and are therefore kept "in place" by centrifugal force.
There IS gravity everywhere... only, if you get far from other massive object, there isn't much.

The answer is no, gravity may be next to nothing in space but it does exist, the weight of a 1000 pound person would probably be so small (a billionth of an ounce or less) we wouldnt really be able to detect it but that person would still have weight regardless.

Depends on gravity.If you are on moon and your weight is lets say 60kg on Earth then you wold weigh 10kgs on moon because the moon's gravity is 6 times less than that on Earth.An astronaut's suit weigh 103kg on Earth.In the dark matter yes, as there will be no gravity at all you would be weightless.

Depending on where you are they would not be weightless but perhaps due to less gravity they would feel light then 1000 lbs.

there is no gravity in the space so if another human have 2000 pound it is also be weightless in space

There would be weight but since there is no gravity (unless he is near another celestial body) he would not feel it. No mater how heavy you are as long as your not close to a object you will seem to be weightless.

1000 pound floating weightless person...ur weight the same, just no gravity...

No gravity means no weight!
moon has like 1/3 gravity of earth so the visitors nearly float on moon...
In space there is no gravity so no weight at all!
be it a pin or blue whale or even our earth.!
have u ever thought why our earth never falls down however it is in mid space?
Because it itself is in SPACE!!!
