No, the earth has a greater pull on a body at the poles, making anything slightly more heavy there. This is for two reason: 1) Because of the shape of the earth, (a slightly flattend sphere) the distance to the core of the planet is greater at the equator and lesser at the poles. Thus, the gravity is greater at the poles. 2) Imagine the earth as a sphere on a vertical stick, spinning really fast. Its not hard to imagine things on the equator being slingshotted away from the earth, while at the top and bottom of the sphere there is no such effect. In reality, ofcourse there is not nearly enough speed for anything to be slingshotted off the earth, but the effect remains in tiny amount, pushing bodies slightly away from the core, and thus creating the effect of decreased weight.
no it depends on gravity. A good example to illustrate this is that the 'big arm' that you sometimes see on TV sticking out of the space shuttle cannot lift its own weight on earth but because it weights alot less in space due to gravity, it is designed to move in space under its own weight with no problems.
No. Weight is technically measured in newton's, which is the unit of force. To solve for force. you multiply an object's mass by the acceleration of gravity (F=ma). Although an object's mass is constant, the acceleration of gravity is slightly different on different places on the planet, so as acceleration of gravity changes, weight changes.

Weight = mass x acceleration due to gravity As acceleration due to gravity remains constant at a given place, weight becomes proportional to the mass
It depends on the level of acceleration in its reference frame. In general, the higher the acceleration, the higher the mass whether the acceleration comes from motion, or a large mass nearby...
The value of universal gravitational Constant(G) doesn't change it is constant at any place in the universe, it's value is 6.67259 x 10-11Nm2/Kg2 But the value of g varies from from place to place on earth,planet to planet and star to star because g=GM/R2 As G is constant g depends on M=mass of planet,R=radius of planet,so g varies with the change in M and R.
All forms of energy follow law of conservation of energy. The total quantum of energy in this universe will always remain constant. Energy can be transferred from one place to another.

The universe is a very big place that is meant to hold planets in place. The universe is huge and has an infinite mass length weight and volume
It seems that there is no such thing as a "center of the Universe". Every place you are, the Universe will look the same.
Yes, an object's weight can change even if its mass remains constant. This happens if it moves to a place with different gravity. An object on the Moon would weigh only one sixth of what it did on Earth.

Weight changes depending on the gravitational pull exerted on an object, i.e. if it is on the Earth or if it is on the moon. Mass, however, remains constant.
It could be nothing because in a fluctuating universe nothing can be in a given place at a given time if the place has not been given or the time,
Your mass is how much matter you are made up of. Your weight is how much force you exert on your surroundings. If the force of gravity is greater or weaker, then your constant mass will exert more, or less force on the surroundings, ie, your weight will be different.
Gravitational force is the force that acts between any two masses in the universe and pull them towards each other weight is the measurement of gravity on an object the more gravity the more weight,an object varies from place to place because gravitational forces vary.
In every culture we find some story about how the universe came to exist in the first place. These are called creation myths.
A change of phase takes place at a constant temperature.
