Answer to Question 1

There is an intense source of radio energy named Sagittarius A at the gravitational center of the galaxy. The source has been shown to be very smallless than 1 AU in size. The source is also associated with X-Ray and infrared radiation. The connection between massive energy output and very small size is explained best by a black hole.
Stars near Sgr A are observed to be orbiting the object at very high speeds. Using the orbital paths of these stars, the object must have a mass of approximately 4 million solar masses. This much mass could only exist in such a small volume of space as a black hole.

Answer to Question 2

True
