听力原文： What is the shape of the universe? The question has baffled and obsessed humankind since civilization first gazed up towards the heavens. The world has yet to receive a satisfactory explanation. Now a new study hints at a possible answer. Contrary to the traditional interpretation, the study suggests the universe is finite and bears a rough resemblance to a soccer ball, or to put it more accurately, the universe looks like a 12-sided volume bounded by pentagons. Based on the new theory, a model has been made to help illustrate the alleged shape of the Universe. If proven by further evidence and inspection, the model would represent a major discovery about the nature of the cosmos. 'What makes the discovery exciting now is it's not a matter of idle speculation,' said Jeffrey Weeks, a US mathematician, 'There's real data to look at and there's the great possibility of getting a definite answer.' Weeks has announced hints that the Universe is actually relatively small, with a hall-of-mirrors illusion which tricks us into thinking that the space stretches on forever. While studying cosmic background radiation observed by NASA's Wilkinson Microwave Anisotropy Probe, Jeffrey Weeks, together with a team of French cosmologists, arrived at this new discovery. It is still in question whether the theory is correct. However, the idea itself is indeed appealing and inspiring.(26)A．A new discovery in Mathematics.B．A new program conducted by NASA.C．A new theory on the shape of the universe.D．A new planet detected in space. 点击查看答案
