It is true that the universe is expanding, and on very large scales, galaxies are moving away from each other. This phenomenon is known as the expansion of the universe. However, it's important to note that the force of gravity operates on much smaller scales, such as within planetary systems like our own.
Gravity is a fundamental force of nature that arises from the interaction of mass and energy. On Earth, the force of gravity is generated by the mass of our planet. When we stand on the surface of the Earth, we feel the force of gravity pulling us toward the center of the planet. This force keeps us grounded and gives us our sensation of weight.
The expansion of the universe does not directly negate or diminish the effects of gravity within a localized system like our solar system or Earth itself. While the universe as a whole may be expanding, the gravitational forces between objects, such as the Earth and its inhabitants, are not affected by this expansion.
It's worth noting that the expansion of the universe primarily influences the large-scale structure of the cosmos and the distances between galaxies. On smaller scales, the effects of gravity dominate, allowing us to experience and observe the familiar forces of gravity in our everyday lives.
