Question

along with a few other related ideas. but almost before he knew it, he had suddenly made our dependable old universe seem strange and new. einsteins spacey ideas before einstein, everyone pretty much thought of space as a sort of blank nothingness that separated objects like planets, solar systems, stars, and galaxies. this nothingness of space was a humongous, rigid background, with all of the matter in the universe arranged on it like pieces on a game board. newtons force of gravity ruled this game, pulling things closer together and making them move against the spacey backdrop of nothingness. but einstein had his own ideas. what if this background wasnt rigid? what if it wasnt black holes. just decades later, they found the first of them. it just goes to show: sometimes, as einstein himself once said, “imagination is more important than knowledge.” which sentence best summarizes the excerpt? einstein opened our minds to amazing new possibilities and showed us that imagination is more important than knowledge. scientists searched the skies for decades before they found the first real black holes. karl schwarzschild used his imagination when he thought about light and extremely distorted parts of space. einsteins idea that space bends inspired scientists to predict and later discover black holes.

Explanation:

The excerpt discusses Einstein's new ideas about space which were different from previous conceptions. It also mentions that his ideas inspired the prediction and discovery of black - holes. The first option is too general about imagination, the second option focuses only on black - hole discovery, and the third option is about Karl Schwarzschild instead of Einstein. The fourth option best captures the essence of how Einstein's space - bending idea led to black - hole predictions and discoveries.

Answer:

Einstein's idea that space bends inspired scientists to predict and later discover black holes.
