Is gravitational force functional in vacuum?
Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.

General relativity predicts that energy is equivalent to mass,and therefore, if the vacuum energy is really there, it should exert a gravitational force. essentially, a non-zero vacuum energy is expected to contribute to cosmological constant, which affects the expansion of the universe.

Is Gravitational Force Functional in Vacuum?
Gravitational force is indeed functional in a vacuum. Let's delve into the details to understand why.
Explanation:
In conclusion, gravitational force is indeed functional in a vacuum and plays a crucial role in shaping the structure and movement of celestial bodies in the universe.
Gravitational force is indeed functional in a vacuum. Let's delve into the details to understand why.
Explanation:
- Gravitational Force: Gravitational force is the attractive force that exists between any two objects with mass. It is one of the four fundamental forces of nature.
- Newton's Law of Universal Gravitation: According to Newton's law of universal gravitation, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
- Effect in Vacuum: Gravitational force does not require a medium to propagate. This means that even in a vacuum, where there is an absence of air or any other material substance, gravitational force still acts between objects.
- Example - Earth and Moon: The gravitational force between the Earth and the Moon is responsible for the Moon orbiting around the Earth even though space is a near-perfect vacuum.
- Universal Nature: Gravitational force is universal and acts over large distances. It is the force that governs the motion of planets, stars, and galaxies in the cosmos.
In conclusion, gravitational force is indeed functional in a vacuum and plays a crucial role in shaping the structure and movement of celestial bodies in the universe.
