In the following line: gravHeading = createVector(otherBodyPosition.sub(this.pos)).heading(); otherBodyPosition.sub(this.pos) is already a Vector. When you try to createVector on that, you're putting a Vector in your Vector, and the .heading() method doesn't know how to resolve that, resulting in the value of gravHeading becoming NaN So when later in, you ...

A body of mass can keep a spacecraft in orbit, if the spacecraft is moving slow enough. If the velocity of the spacecraft is too high, it escapes. This limit is the escape velocity. Escape velocity depends on both distance and the mass of the body: $$v_e = \sqrt{\frac{2GM}{r}}$$ Where $G$ is the universal gravitational constant, $M$ is the mass of the ...

The engineers answer: the rope will break. The physicist answer: the rope will pull the two spaceships inside the black hole. So you are asking in a "non-pragmatic" way: the physicist answer... Why? E: Coming near a black hole, the gravitational forces of the black hole will pull more and more jet not equal through the whole lenght. The shear ...

If the ends of the rope are constrained to move along straight lines past the black hole, the rope breaks. The effect of gravity of a massive body varies inversely with the square of distance from the object’s center of mass. For small objects near ordinary massive bodies this gravitational gradient is small, but near a black hole the gradient gets very ...
