FTL with fast-moving large mass

# Could this FTL idea with a fast moving large mass be possible?

I have recently come up with a possible way to achieve faster-than-light (FTL) travel by using a high speed singularity or large mass.

## Background

As everyone knows, according to relativity, under normal conditions, it is impossible for anything initially slower than light become as fast as light or even faster, because anything with mass requires infinite energy to approach speed of light.

However, speed is not the only factor of relativity, gravity will affect it as well. There was an [experiment](https://en.wikipedia.org/wiki/Tests_of_general_relativity) shows that even light will bend as it travels near a strong gravitational field, for example Sun. That observation shows space can be stretched with strong gravity, and give some insight to this idea.

## Observations

The experiment shows that if we take a point of observation in a position of small gravity, let say $w$, to observe something that travels along/near another point of observation, let say $s$, that is in effect of strong gravity. The speed we observes in $w$ will be slower than that of in $s$, that is $v_w<v_s$, where $v_s=c$ in this case.

## Theory

How if we actually what moving is Sun itself, instead of object around it? Let's assume it moves in a speed $v=0.5c$, that is quite slow, but what is its speed to a point of observation with much smaller gravitational field, let say our Earth? Since the space around Sun is stretched according to our observation, if the Sun travels $1\mathrm{km}$, we should see it traveled more than $1\mathrm{km}$ since the space around it is stretched to us, right? We let such ratio be $r$, where $r>1$. 

Let's consider the new $v$ that is very close to $c$, let say $0.9999 c$. Given a $r>1$, let say $1.1$, aren't we are going to observe that the Sun travels faster than $c$ since $0.9999 c\times 1.1>c$? The Sun is moving FTL according to our observation! right? This way does not need any sort of subspace or even harder solutions, we just need a large mass and enough energy to push it fast enough. And this way does comply with relativity if we pit Sun as our point of observation, right?

## Possible ways of testing

Although it is not so possible to let the Sun move in that speed, I believe we will be able to push Moon or other lighter mass to that kind of speed one day, and observes what will happen.

I think that is quite possible to create a small singularity or just some denser matter with those experiment devices we have today, and we can test the theory.

## Conclusion

Can some experts on relativity tell me if there are any logical errors or mistakes in this dumb theory?
