The correct answer is a black hole. To arrive at this answer, we can first determine that the question is referring to the center of the Milky Way galaxy. To find out what lies at the center, we can rely on scientific knowledge and observations.
One way to determine the answer is through studying the movement of stars near the galactic center. Scientists have discovered that these stars exhibit unusual behavior, such as moving at high velocities. This behavior led scientists to conclude that a massive object with a strong gravitational pull must be present at the center. The most likely explanation for this is the presence of a supermassive black hole.
To further support this conclusion, in 1974, astronomers discovered an object called Sagittarius A* (pronounced "Sagittarius A-star") at the center of the Milky Way. Observations of its orbiting stars have provided strong evidence for the existence of a supermassive black hole, with an estimated mass of over four million times that of our sun.
Therefore, based on scientific research and observations, we can confidently say that a black hole lies at the center of the Milky Way galaxy.
