Albert Einstein first hypothesized that a large object, such as a planet, bends the space around it. This hypothesis became part of the theory of relativity, which is about how objects affect the space and time around them. What did this hypothesis most likely need before it became part of an accepted theory? other scientists asking the same question other questions about mass and space experimental evidence that mass is not related to space experimental evidence supporting the hypothesis

Einstein's theory of relativity gained a great deal of credibility by successfully predictingGroup of answer choicesThat light travels in straight linesThat light is a gasThat light comes from starsThat light "bends" around massive objects

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.

The law of universal gravitation states that both mass and distance of objects affect the gravitational force between them. Gravitational force increases as the mass of the objects increase. Gravitational force decreases as distance between the objects increases. Why are these statements considered scientific law, and not scientific theory?Group of answer choicesThe statements predict what will happen under certain conditions.The statements tells what happens, and not why it happens.The statements explain the attractive force between two objects.The statements involve mass and distance measurements.

Which of the following is the most widely accepted explanation for the origin of our solar system? aThe big bang theory, which states that an infinitely small, infinitely dense particle exploded to create our solar system. bThe steady state theory, which states that all regions of the universe, including our solar system, have always existed in their current forms. cThe giant impact hypothesis, which states that the planets and other bodies in our solar system resulted from collisions between the sun and various large bodies. dThe nebular hypothesis, which states that gravity caused a small fragment of a huge, rotating cloud of space dust and gas to collapse, forming a large accretion disc that became the sun and planets.

The beginning of modern astronomy can be traced back to Nicolaus Copernicus and his book, On the Revolution of Heavenly Spheres. What theory did Copernicus promote in this book, which was in conflict with the teachings of the Catholic Church? A. The Earth’s wobble on its axis produced seasonal changes. B. Planets rotated on mini-orbits around the Earth. C. The Earth was not the center of the universe. D. The center of the universe is far beyond the stars.
