# Exploring the Gravity Field in Caves and Homogeneous Spheres: Expert Insights

• kram83
In summary, gravity is a natural phenomenon that causes objects with mass to be attracted to each other. It is caused by the curvature of spacetime created by massive objects and was first mathematically described by Sir Isaac Newton in the 17th century. Gravity cannot be turned off, but its effects can be counteracted in certain situations. According to Einstein's theory of general relativity, gravity can also affect the passage of time through gravitational time dilation.

guys i need help...do u know the answer of this question?

How large will be the gravity field in a cave (compare with the field in a homogeneus sphere)?

Thz

Kram

Your question is a little too vague. It depends on the geometry.

## 1. What is gravity?

Gravity is the natural phenomenon by which all objects with mass are brought towards each other. It is the force that keeps planets in orbit around the sun, and objects on Earth from floating away.

## 2. How does gravity work?

Gravity is caused by the curvature of spacetime created by massive objects. The more massive an object is, the more it bends the fabric of spacetime, causing other objects to be pulled towards it.

## 3. Who discovered gravity?

The concept of gravity has been known since ancient times, but it was Sir Isaac Newton who first described it mathematically in his theory of universal gravitation in the 17th century.

## 4. Can gravity be turned off?

No, gravity is a fundamental force of nature and cannot be turned off or manipulated by humans. However, there are certain situations where the effects of gravity can be counteracted, such as in outer space or on a zero-gravity flight.

## 5. How does gravity affect time?

According to Einstein's theory of general relativity, gravity can affect the passage of time. The closer an object is to a massive object, the slower time will pass for that object. This is known as gravitational time dilation.
