Linearized gravity

Okay, let’s start with a question - do you know what gravity is?

No? Okay, let’s learn that first. Gravity is the force that pulls objects toward each other. For example, if you throw a ball in the air, it falls back to the ground because of gravity.

Now, imagine you drop a pencil from your hand. It falls straight down toward the ground because of gravity. But, what if you are on a rocket ship in space, and you drop the same pencil? It still falls toward the ground of the rocket ship, and it still happens because of gravity.

That’s because gravity exists everywhere in the universe, and it affects all objects regardless of where they are.

So what does Linearized Gravity mean then?

Scientists use complex mathematical equations to understand how gravity works. They use these equations to predict things like how planets move around the sun or how stars move around galaxies.

But sometimes, these calculations can be too complicated to solve. And that's where Linearized Gravity comes in!

Linearized Gravity is a simplified version of gravity that scientists can use to make these predictions. It's like using a calculator instead of doing math in your head.

Instead of using all the complicated equations, scientists start with a simple equation. They add a little bit more complexity to it, then a little bit more, until they have something that is still accurate but much easier to work with.

Think of it like building a puzzle - they start with simple pieces and gradually add more until they get closer to solving the whole puzzle.

So, in conclusion, Linearized Gravity is a way that scientists can make predictions about how things move in space by using a simplified version of the complicated math equations that describe gravity.
