Here's why:
* Gravity is a fundamental force: It's one of the four fundamental forces of nature, along with electromagnetism, the strong force, and the weak force.
* It's always attractive: Gravity always pulls objects towards each other. The more massive an object is, the stronger its gravitational pull.
* It affects everything: Every object with mass exerts a gravitational force on every other object with mass.
* Earth's gravity: The Earth has a large mass, so it exerts a strong gravitational pull on everything around it, including us! This is why we feel grounded and why objects fall to the ground when we drop them.
So, while we can't see gravity, its effects are undeniably real and very noticeable!
