The answer is Galileo.
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
The study of heavens is called astronomy. It involves the observation and analysis of celestial objects and phenomena in the universe, such as stars, planets, galaxies, and outer space.
The telescope was invented in 1620 so they used that. Man's observation of the stars and planets has been going on thousands of years.
This statement was made by Niels Bohr as part of his atomic model, which suggested that electrons orbit the nucleus of an atom in specific energy levels, much like planets orbiting the sun.
Earth science is the study of the planet Earth, which includes geology, Biology, oceanography and atmospheric sciences, amongst many others.
Observation alone is usually not enough to determine the type of bond a substance has. Additional experiments and analysis, such as spectroscopy or crystallography, are often needed to accurately determine the type of bond present in a substance.
Galileo's observation was that all the planets revoled around the earth and he though earth was a middle planet

Nicolaus Copernicus in 1543.
It means, what do you understand from the observations. Like, is a certain process or reaction suggested to occur?
The nature of a substance is determined through various types of observation and testing.
Galileo
By a simple observation; also a semisolid substance can flow without any stress.
An observation is quantitative if it has something to do with the amount of the substance or measurements.
An example of a quantitative observation is measuring the temperature of a substance using a thermometer and finding it to be 25 degrees Celsius.
A quantitative observation involves looking at the numerical aspects and properties of a substance. For instance, there are are 3.0 grams of sodium chloride in this weighboat. A qualitative observation is any observation that involves the qualities outside of the numerical aspects. For example, the sodium chloride is white.
