No visible light can escape the strong gravity
of a black hole. This makes black holes
invisible—and very difficult to study. But
scientists make new discoveries and develop
new theories about these mysterious objects
every day. In 2015, astronomers were able
to finally confirm a theory that Einstein had
developed one hundred years earlier! And
in 2016, scientists found that black holes
may form in a different way than they ever
thought possible. Read this book to learn
more about the incredible and mind-boggling
science of black holes.
