Chapter 34, Problem 1RAT
Scientists estimate the age of universe to be about
(a) 5000 years old.
(b) 1 billion years old.
(c) 14 billion years old.
(d) 42 billion years old.
Expert Solution & Answer
To determine
The correct option for the statement “Scientists estimate the age of the universe to be about”.
Answer to Problem 1RAT
The correct option for the statement “Scientists estimate the age of the universe to be about” is option (c).
Explanation of Solution
In the branch of physics cosmology, the time elapsed after the event of the big bang is considered as the age of the universe. These estimations are based on the studies performed by scientists over the course of time using studies of the microwave background radiation by the Planck spacecraft, the Wilkinson Microwave Anisotropy Probe.
The current estimation of the age of the universe is 14 billion years, with a narrowed uncertainty of 20 million years. Measurements of the cosmic background radiation give the cooling time of the universe since the Big Bang.
Conclusion:
Therefore, the correct option for the statement “Scientists estimate the age of the universe to be about” is option (c).
