    Gravity
In summary, the conversation discusses the concept of gravity as a property of spacetime curvature and its relation to the mass of objects. The question is raised whether gravity can exist without the existence of spacetime. It is argued that without the concept of spacetime, the concept of gravity cannot be defined and physics would not exist.

So I have a question.As GR states that gravity is a property of spacetime curvature.
So for example as the sun having the biggest weight in our solar system it sits in the middle "like a boss" , or in curvature it is the deepest and the other planets orbit it and are higher standing because being lighter? I feel this is not a very good interpretation but still am doing my best.
So if gravity is the property of space/time curving then if there would be no space/time there would be no gravity? Or gravity can exist without the existence of space/time.
The question is: Are they basically understood together or can we say that we could have gravity just from mass of an object but without the 4th dimension that I guess would be time?Thanks for your responses,
Girts.

How would you define "gravity" without a spacetime? Without the concept of a spacetime (or concepts very similar to this), you cannot have physical objects in a spacetime, and you don't have physics at all.

Spacetime is a type of mathematical space with a co-ordinate system in which measurements are made, it is not a thing like a carrot or a mosquito.
 

1. What is gravity?

Gravity is a natural force that causes objects with mass to be attracted to each other. It is responsible for keeping planets in orbit around the sun and objects on Earth from floating away into space.

2. How does gravity work?

Gravity works by creating a force between two objects with mass. The more massive an object is, the more gravitational force it has. The force of gravity also depends on the distance between the two objects, with a stronger force occurring when the objects are closer together.

3. Who discovered gravity?

Sir Isaac Newton is credited with discovering the concept of gravity in the late 17th century. However, the ancient Greek philosopher Aristotle had also theorized about the force of gravity many years earlier.

4. What is the difference between mass and weight?

Mass is a measure of the amount of matter an object contains, while weight is a measure of the force of gravity acting on an object. Mass remains the same regardless of location, while weight can vary depending on the strength of gravity in different locations.

5. Can gravity be manipulated or controlled?

No, gravity is a fundamental force of nature that cannot be manipulated or controlled. However, its effects can be counteracted by other forces, such as the force of lift in an airplane, or the force of magnetism in a levitating object.
