The most suitable option for the completion of the sentence "Most of the matter that exists in the universe will go through the..." is:
E. black holes
Explanation:
1. Black holes are extremely dense regions in space where gravity is so strong that nothing, not even light, can escape from them.
2. Over time, as matter in the universe ages and evolves, a significant amount of it will be drawn towards black holes due to their immense gravitational pull.
3. Matter that gets close enough to a black hole's event horizon, known as the point of no return, gets pulled into the black hole.
4. Once matter enters a black hole, it is believed to be crushed to a point of infinite density, forming what is known as a singularity.
5. Therefore, black holes play a crucial role in the life cycle of matter in the universe by absorbing and processing vast amounts of material over time.
