Quiz: The Big Bang Theory p » Select the best answer. is the breakdown for the composition of the universe by element? ~75% hydrogen, ~23% helium, and ~2% all other elements ~75% helium, ~23% hydrogen, and ~2% all other elements ~75% all other elements, ~23% helium, and ~2% hydrogen ~75% hydrogen, ~23% all other elements, and ~2% helium 1 point # Select the best answer. Which of the following is true about the Big Bang Theory? o The Big Bang Theory states that the universe expanded from a single point and has stopped expanding. The Big Bang Theory states that the universe used to be much cooler and smaller in the past. “ The Big Bang Theory is a best-guess explanation for how the universe began. The Big Bang Theory is the scientific explanation of how the universe began and evolved over time. The Big Bang Theory cannot change. K] 1 point }9 Select the best answer. Which of the following is NOT evidence of the Big Bang Theory? @S!ars have red shifted because they were moving towards each other. Abundance of hydrogen and helium Galaxies have been observed to be red shifted. Cosmic microwave background radiation can be observed in every direction. o » True or False. The doppler effect can be observed when two objects are very far away and stationary relative to one another. True G False 1 point & Matching. Blue Shift shorter wavelengths v Radio waves lowest frequency b Gamma waves highest frequency v 1 point Ps Select the best answer. What object in the cosmos continues to create heavier elements? ck holes rs dark matter planets Lpane * Select ALL THAT APPLY. id we find out what was the composition of the universe? Using ground and space based observatories, we took images of parts of the universe and determined the composition of the whole universe based on data from those parts. We looked at some parts of the universe to make an educated guess of the composition of the whole universe. ‘e assumed that most of the universe started with hydrogen and worked forwards based on the number of observed stars and their potential for fusing heavier elements. We observed the whole universe and analyzed the data to determine the composition of the universe. 1 point ;? What is the cosmic microwave background radiation? The first event that happend during the Big Bang The leftover heat and energy from the Big Bang. The shape of the universe as seen from space based observatories such as the James Webb telescope. o Galaxies that have red shifted so far that their electromagnetic waves have shifted to the microwave part of the electromagnetic spectrum. 1 point )9‘ Select the best answer. The galaxies that we observe are all red shifted, relative to our position among the stars. is means that the universe as a whole is spreading apart. his means that we are blue shifting. This means that we are the center of the Big Bang. This means that the universe is expanding in all directions and we are stationary.
