Identify three (3) specific challenges to making direct measurements in the fields of astronomy, chemistry, physics, or earth science. Describe how scientists have utilized indirect forms of measure to overcome these challenges
Since the ancient times people have always been attracted to the unknown. Humans have always been curious about everything they have come across; How big is our earth?, how deep is the sea? Are there any other lands past the horizon?, and how big is our universe?. These types of questions have always led humans to forcefully exercise their minds into figuring them out. Till today some of these questions still roaming around waiting for answer to be assigned to them. Astronomy is a natural science that deals with the study of celestial objects such as: moons, planets, stars, nebulae, and galaxies. (konrad B. Krauskopf, 2012). Astronomy is one of the oldest sciences. Is known that astronomy has been exercised by different civilizations like the Babylonians, Mayans, Indians, Chinese, and the Greek. Most of them kept track of the skies by following the movement of objects through out the years.
One of the main issues they came across was finding out the precise distances of planets and stars form Earth. However, through out the years astronomers have been able to figure out ways to overcome these issues. One way to figure out the accurate distance of objects in our universe is by using the Luminosity and Brightness of the astronomical objects. Luminosity is the measurement of brightness or amount of energy emitted by any form of matter in our universe. (Muldrew, 2012). This means that the distance is calculated by measuring the time it takes light of a star to reach us here in earth.
In chemistry one of the biggest challenges that chemists have encounter has been calculating the amount of
