Summarize the central idea of a passage
what is the central idea of this passage from
tyson's essay?
o black holes and stars are both gigantic balls
of gas.
black holes are a dangerous and powerful
force in the universe.
since stars are 100 percent certified balls of
gas, they are not immune from the fate that
greeted our hapless clouds. if one star in a
binary system becomes a black hole, then the
black hole does not get to eat until late in the
companion star's life, when it swells to
become a red giant. if the red giant grows
large enough, then it will ultimately get
flayed, as the black hole peels and eats the
star, layer by layer. but for a star that just
happens to wander into the neighborhood,
tidal forces will initially stretch it, but
eventually, differential rotation will shear the
star into a friction-heated disk of highly
black holes eat anything that comes within
their reach
red giants are protected from black holes by
their size.
