In 1964 the Nobel Laureate Roger Penrose established the mathematical theory to describe how a black hole could exist. He derived his theory from Albert Einstein’s general theory of relativity and demonstrated that the formation of black holes was a natural process in which a supermassive object accumulates a gravitational force so great that nothing, not even light, can escape it. More perplexing, Penrose explained that at the center of a black hole as a singularity at which all known laws of nature dissolve. Which choice best states the main idea of the text?Choose 1 answer:Roger Penrose used mathematical theory to describe properties of black holes and demonstrate how black holes are formed.eliminateRoger Penrose described a novel mathematical theory based on Albert Einstein’s work.eliminateBlack holes are supermassive objects with a central singularity at which all known laws of nature dissolve.eliminateBefore Roger Penrose, no physicist was able to describe a mathematical theory to explain how black holes are formed.

Scientists presently have two theories on how the first supermassive black holes formed: one theory suggests black holes formed from a collapsing star and grew over time; the second theory suggests the collapse of large clouds of gases caused supermassive black holes to form immediately. The recent discovery of a supermassive black hole, UHZ1, supports the second theory. According to scientists, the energy emitted from the black hole suggests that, in its early days, the black hole already weighed as much as all the stars in its galaxy. Which finding, if true, would most directly weaken the second theory described in the passage?The discovery of a supermassive blackhole that had a comparatively small mass in its early dayseliminateThe discovery of a collapsing star in a galaxy millions of light years awayeliminateThe observation of a large cloud of gas collapsing and forming into a black holeeliminateThe emergence of new data suggesting that the size of blackholes is best measured through the use of x-rays

In 1687, Isaac Newton published a book explaining his three laws of planetary motion and the law of gravity. The importance of these discoveries was his general theory that A. the behavior of nature is basically unpredictable. B. nature consists of unpredictable acts of deities. C. all of nature follows uniform, unchanging laws. D. astronomical objects cannot be described using math.
