Direct verification of these ideas may prove to be exceedingly difficult, but indirect verification may be within reach. We sometimes forget that much of astronomical science is done indirectly. For example, no one has ever visited the Sun or the stars, yet we know what the stars are made of by analyzing the light given off by these luminous objects. By analyzing the spectrum of light within starlight, we know indirectly that the stars are made primarily of hydrogen and some helium. Likewise, no one has ever seen a black hole, and in fact black holes are invisible and cannot be directly seen.
