Pick the correct statement:
1. The VLA collects stardust from space which we can see with our eyes.

2. The VLA collects radio light from space which we cannot see with our eyes.
Is the force of gravity stronger between
two humans which are 10,000 miles apart or two massive planets which are 10,000 miles apart? Explain.
The force of gravity is stronger between two massive planets. The force of gravity depends on the mass of the two objects and the distance between them. Because in both examples the objects are the same distance apart and planets are more massive than people, the two planets have stronger gravity between them.
Which statement is true? (A or B)
A. Astronomers have determined that the Universe is infinitely old.
B. Astronomers have determined that the Universe is about 13.6 billion years old.
B. Astronomers have determined that the Universe is about 13.6 billion years old.
