Gravity is a force that attracts objects with mass towards each other. It is responsible for keeping planets in orbit around the sun and objects on Earth from floating off into space.
The strength of gravity on a planet depends on its mass and size. Therefore, the larger and more massive a planet is, the stronger its gravitational pull. For example, Jupiter has more than twice the mass of Earth and has a much stronger gravitational force.
Humans have evolved to thrive in Earth's gravity and would likely have difficulty living on a planet with significantly stronger or weaker gravity. However, with the right technology and adaptations, it is possible for humans to survive on other planets with different levels of gravity.
In space, there is very little gravity due to the vast distances from massive objects. This lack of gravitational pull allows astronauts to appear weightless and float around in their spacecraft.
No, the strength of gravity can vary throughout the universe. It depends on the mass and distance of objects in space. Additionally, the theory of general relativity suggests that gravity can be affected by the curvature of space-time.
