# astro: when an unlucky star ventures close enough to a black hole, it spaghettifies ...

<< To be disrupted, an unlucky star must venture close enough to a black hole that gravitational tides exceed the internal gravity that binds the star together. In other words, the difference in the black hole's gravitational pull on the near and far sides of the star, along with the inertial pull as the star swings around the black hole, stretches the star out into a stream. "Basically it spaghettifies," >> James Guillochon
