Answer:
Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.
"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."
A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
Answer:
Tribalism developed in the early 1900s and encouraged the nationalist spirit of Africans throughout the world.(B.)
Density, because the core is made of metals like iron and nickel
Answer:
Environmental determinism is the idea that the physical environment, climate and geographical conditions shape human thoughts, actions and behavior. Possibilism refers to the theory that the environment imposes certain constraints or limitations, but culture is otherwise determined by human actions.
