Answer:
1 light year is 63,270 AU, which means that the distance to the nearest star is 272,061 AU. We took the radius of the solar system to be 39.5 AU, which means it has a diameter of 79 AU.

Answer:
Explanation:
The history of humanity from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human bieings that we are today evoled from many years ago some say from the begining of time— it is connected to climate variation and change. Human biens has experienced nearly two full glacial-interglacial cycles, but its global geographical expansion, massive population increase, cultural diversification, and worldwide ecological domination began only during the last glacial period and accelerated during the last glacial-interglacial transition. The first bipedal apes appeared in a time of climatic transition and variation, and Homo erectus, an extinct species possibly ancestral to modern humans, originated during the colder Pleistocene Epoch and survived both the transition period and multiple glacial-interglacial cycles. Thus, it can be said that climate variation has been the midwife of humanity and its various cultures and civilizations.
Answer:
The given blank can be filled with the steady state theory.
Explanation:
The theory based on the perfect cosmological principle is the steady-state theory. On the basis of this theory, the universe is isotropic, homogenous, and immutable. This hypothesis did not reject the expansion of the universe, however, it believed in the spontaneous generation of matter to counteract the observed expansion, that is, maintaining the average density same.
This theory was suggested by Bondi, Hoyle, and Gold in 1948. The steady-state theory lost its objectives when the discovery of the cosmic background radiation was done.
