Read this paragraph about black holes. If a car fell into a black hole, the tidal force of gravity would rip the car apart. It would work like this: The gravity force would increase as the black hole pulled the car inside. The front wheels would be pulled in faster than the back wheels, until the car stretched and ripped apart. The gravitational pull of a black hole is inexorable; there is no turning back from it.

What does the word inexorable mean?

powerful
amazing
irresistible
awesom
