Question

1. What did observations between 1912 and 1917 show?_____

Answer 1

The following set of prompts is astronomy related.

1) It is to be noted that the observations between 1912 and 1917  revealed that the earth was millions of years old and cooled down from a once molten state.

2) Lemaitres argued that the physical world began as a single particle—the "primeval atom," as he termed it—that disintegrated in an explosion, resulting in space and time and the cosmos' ongoing expansion.

3) It is TRUE to state that between 1912 and 1922, astronomer Vesto Slipher at the Lowell Observatory in Arizona uncovered that the spectra of light from many of these celestial entities were systematically shifted to longer wavelengths, or redshifted. The objects referenced here were galaxies in the distance.

4)  The important discovery that Hubble and his assistant discovered about galaxies was that some nebulae were galaxies expanding beyond our own galaxies.

5) It means that the universe has been growing or expanding ever since the Big Bang.

6) By observing very distant objects, scientists can tell whether or not the universe is moving, growing, or shrinking. This concept is referred to as redshift.

7) In 1965, the American Radio Astronomers Arno Penzias and Robert Wilson inadvertently discovered Cosmic Microwave Background Radiation.

8) According to all recent observations and studies, the Universe has no center.

9) It is estimated the Universe is 13.8 Billion Years old.

10) According to the Big Bang Theory, the whole Universe existed within a bubble millions of times smaller than the size of a pinhead. It was hotter and denser than we could have imagined. Then it burst into flames. According to this belief, this explosion produced life as we know it. It should be highlighted that, while the hypothesis has been utilized to explain numerous scientific facts, it is still an unproven theory.

When did the study of astronomy begin?

The Assyro-Babylonians made the earliest written records of regular astronomical observations approximately 1000 BCE. Astronomers had built an extensive knowledge of the celestial bodies and documented their periodic movements in Mesopotamia, which is located in the southern section of modern-day Iraq.

Astronomy is the oldest natural science, dating back to antiquity, with roots in prehistoric religious, mythical, cosmological, calendrical, and astrological beliefs and practices: vestiges of these can still be found in astrology, a discipline long intertwined with public and governmental astronomy.
