No, it is not true that some parts of the Earth don't have the force of gravity. Gravity is a fundamental force of nature that exists everywhere on Earth. It is what gives weight to objects and keeps them anchored to the surface of the planet.
Gravity is a result of the mass of an object. Every object with mass exerts a gravitational pull on other objects. The force of gravity is dependent on the mass of the objects involved and the distance between them. On Earth, the force of gravity is relatively consistent across the planet's surface, although it can vary slightly due to factors such as changes in altitude or local geological features.
It is possible for objects to experience variations in gravitational force depending on their proximity to other massive objects or the influence of other factors. For example, gravitational force can be slightly weaker at high altitudes compared to sea level due to the increased distance from the Earth's center. Additionally, local variations in gravitational force can occur due to the presence of mountains, underground structures, or dense mineral deposits. However, these variations are relatively small and do not result in the complete absence of gravity in any location on Earth.
In summary, gravity is a universal force that exists everywhere on Earth, and there are no locations on Earth's surface where the force of gravity is entirely absent.
