Does time move in a straight line excluding spacetime gravity changes or in a wave and if a wave do you travel on the wave or through it?
Cteccles
In the geometric treatment of spacetime, time is a linear dimension. A given particle could have a straight or curved track in spacetime, but time itself is a straight line.

How does mass effect gravitational force?
There is no such thing as gravitational force. Mass curves spacetime and stuff moves through spacetime in straight spacetime paths. The effect of this is what we call gravity. The more the mass the greater the curvature of spacetime.
Does gravity have an affect on photons?
Gravity deforms spacetime, and photons follow the curves in spacetime that are put there by objects with large mass (and, therefore, large gravity).
What is the benefit of a fixed pulley?
a fixed pulley changes the direction you are executing the force in. fixed pulleys are made to work with gravity which makes the work you must use less than if you were lifting straight up and against gravity.
How is gravity generated?
Gravity is not generated. There are two main explanations of gravity, either general relativity, or an explanation which uses quantum mechanics. According to general relativity, gravity alteres spacetime. This causes a spacetime curvature, which is responsible for the fact that masses atracct one another. According to the other theory, it is the result of the exchanges of virtual gravitons. Since gravitons have not been observed yet, most physicists accept general relativity as the explanation. Other theories exist, but not enough evidence has been gathered so far.
Which fundamental force is the result of warped spacetime?
I have no idea which fundamental force is the result of warped space time. However, gravity will create warped space time.

Is gravity a force or a bend in spacetime?
Gravity is a force, not a bend in spacetime.
What causes gravity according to the Einstein's theory of general relativity?
Gravity, according to Einstein, is caused by matter and energy which bends spacetime. This deformed spacetime then gives the appearance of gravity even though objects are traveling in straight lines in a curved space.
Is gravity a force or not?
gravity not as a force, but as the curvature of spacetime

Gravity deforms spacetime, and photons follow the curves in spacetime that are put there by objects with large mass (and, therefore, large gravity).
Is the sun's gravity stronger than the earth's?
Yes, the sun has much more mass than the earth so the sun warps spacetime much more than the earth warps spacetime. The amount that spacetime is warped by an object is proportional to the strength of that object's gravity.

What is the reason behind gravitation?
Based on Einstein's theory of relativity, spacetime is curved around massive objects, and gravity "acting" on objects is actually just the objects following this curve in spacetime. Gravity is not a force.
Why is gravity the center of the earth?
It isn't. Gravity is a force created by mass in spacetime; the centre of the Earth is a particle of matter.
How light attracted by black hole even light has no weight?
According to the general theory of relativity, gravity does not attract; instead gravity bends spacetime. Objects always follow locally straight lines of motion, but in bent spacetime a locally straight line of motion is not globally straight, instead it is globally bent. Thus it does not matter if an object passing near a black hole has mass or not, its path will bend toward the black hole. Note: do not confuse mass and weight. In free fall all objects, whether they have mass or not, have no weight.
How come gravity doesn't get trapped in a black hole?
Gravity does not escape, its not a thing, it is the warping of spacetime produced by mass. A black hole has lots of mass packed in a very tiny volume so it warps spacetime quite significantly, producing strong gravity around it.
How do you write a sentence about gravity with the word planets in the sentence?
A planets gravity is caused by the distorting effect its mass has on the fabric of spacetime.
