describe the formation and nature of singularities
explain why large numbers of stars become singularities
compare the characteristics of singularities with those of stars
explain what happens during the stages of a singularitys formation
imply that singularities could be more easily studied if observers could get closer to them
26. The passage suggests which of the following about the Sun?
I. The Sun could evolve to a stage of collapse that is less dense than a singularity.
II. In the Sun, the inward force of gravity is balanced by the generation of heat.
III. The Sun emits more observable light than does a white dwarf or a neutron star.
I only
III only
I and II only
II and III only
I, II, and III
27. Which of the following sentences would most probably follow the last sentence of the passage?
Thus, a physicist interested in studying phenomena near singularities would necessarily hope to find a singularity with a measurable gravitational field.
Accordingly, physicists to date have been unable to observe directly any singularity.
It is specifically this startling phenomenon that has allowed us to codify the scant information currently available about singularities.
