Is there a distance where the curvature in spacetime created by an object's mass ends? Is it a finite gravity well or does the curvature just get infinitely weaker?
Yes, gravitational attraction is affected by the distance between two objects. The force of gravitational attraction decreases as the distance between the two objects increases. This is known as the inverse-square law, which means that the force is inversely proportional to the square of the distance between the objects.
According to our current understanding of physics, there is no limit to the strength of gravitational attraction. The force of gravity can become infinitely strong as the distance between two objects approaches zero. However, as the objects get closer, other factors such as quantum effects come into play and our current understanding of gravity breaks down.
Yes, gravitational attraction can exist between objects that are not in direct contact. This is known as action-at-a-distance, where objects can exert a force on each other without physically touching. Gravitational attraction is a perfect example of this phenomenon as it can act between objects that are millions of miles apart.
Yes, gravitational attraction is a universal force. This means that it acts between all objects with mass in the universe. Even small objects, such as atoms, exert a tiny gravitational force on each other. This is why gravity is such a dominant force in the universe, shaping the movements of planets, stars, and galaxies.
No, gravitational attraction cannot be shielded or cancelled out. Unlike other forces, such as electromagnetism, there is no known way to block or negate the effects of gravity. Even objects with no mass, such as light photons, are affected by gravity. However, the effects of gravity can be counteracted by other forces, such as the centrifugal force of a spinning object.
