- Could black holes be used for swing-by? 3 answers
In our space missions, we use gravity assists by planets to change the speed relative to the sun. The speed relative to planets remains the same. We cannot use the sun for gravity assists.
In Interstellar movie, the black hole was the center of their system and their velocities were relative to it. So using it as means to get higher velocity correct? Am I missing something in this?
