Question

3 multiple choice 1 point how old is the universe? infinite number of years 4.5 million years 4.5 billion years 14 billion years

Explanation:

The age of the universe is a topic in Natural Science (specifically Astronomy, a subfield of Physics or Natural Science). Scientific research, including cosmic microwave background radiation studies and Hubble's law applications, indicates the universe is approximately 14 billion years old. The other options are incorrect: "infinite" contradicts current scientific models, 4.5 million is too young, and 4.5 billion is the age of the Earth.

Answer:

D. 14 billion years
