Your eyes close with muscles not gravity.
People are weightless if in zero gravity in outer space. On earth, weightlessness can be simulated for training in a rapidly descending aeroplane.
Yes, a man can lift one sack of rice in outer space because there is no gravity to counteract the movement. However, he will need to be careful about controlling the sack's movement since it will float freely in the weightless environment.
Without the effects of gravity the person will be weightless.
The force of gravity decreases as distance from the center of the gravitational field increases. Objects in outer space are generally millions of miles from the closest massive source of gravity, which makes them seem weightless. In reality, their weight is existent, but extremely close to zero.

Without gravity, you would be weightless, as in the vacuum of outer space. It is the gravity of the Earth that gives us our weight.
They don't. The moon has gravity but not as much as earth so they feel that they have less weight. In outer space a person would feel weightless because no gravity that they could notice is acting upon them.
Yes.
No, one ton would not float in outer space because weightlessness in space is due to the absence of gravity, not because of buoyant forces. In space, objects with mass will still have weight but will appear weightless due to the lack of a gravitational force pulling them down.
Organisms from earth, cannot live in outer space. They need a stable environment and a place to evolve and reproduce. Outer space, does not have a stable environment it gets hot then cold in a matter of seconds. If you really think about it, what would the organisms eat? There's nothing in outer space that would provide them with food.
In the center of the Earth, the gravitational forces from all directions cancel each other out, resulting in a net zero gravitational force, making you weightless. In outer space, there is no surrounding mass or gravity pulling on you, so there is no force acting on you to counteract your weight, leading to a sensation of weightlessness.
yes there are
