How does gravity work in space?

Gravity in space works similarly to how it does on Earth, but its effects can be more complex due to the vast distances and the presence of massive objects.

So, does that mean there's no gravity in space?

Not at all! There is gravity in space; it's just weaker the farther you are from a massive object. For example, astronauts on the International Space Station experience microgravity, but they are still under the influence of Earth's gravity.

What causes gravity in the first place?

Gravity is caused by mass. The more massive an object, the stronger its gravitational pull. This is described by Newton's law of universal gravitation.

How does this affect space travel?

Understanding gravity is crucial for space travel. It helps in calculating trajectories, fuel requirements, and ensuring spacecraft can enter or exit orbits effectively.

Can gravity be manipulated or changed?

Currently, we cannot manipulate gravity in the way we can with other forces. However, theories like general relativity suggest that massive objects can warp spacetime, affecting how gravity is experienced.
