Final answer:
Einstein's theory of relativity supports the Big Bang theory by suggesting that the universe originated from a single point. This core concept of the Big Bang is reflected in Einstein's relativity, which revolutionized our understanding of time and space.
Step-by-step explanation:
Albert Einstein's theory of relativity is foundational in understanding the Big Bang theory. The theory predicts that the universe originated from a single, small point, which aligns with the Big Bang theory stating that the universe began with a primeval explosion. Einstein's theory does not support the notions that the universe is infinitely large and old, that the speed of light has increased over time, that energy cannot be transformed into matter, or that the size of an object is independent of its velocity. By observing phenomena at high speeds, Einstein concluded that both time and space are relative, meaning objects in motion at high speeds appear shorter and time passes more slowly for them, compared to when measured at rest.
