你为什么要伪造一个宇宙？原因之一是为了更好地了解我们真实的宇宙。现在，许多试图了解宇宙特性的天文项目都是从一台机器人望远镜开始的，它可以连续拍摄夜空的图像。接下来，复杂的计算机算法处理这些数字图像，找到恒星和星系，并测量它们的特性。为了校准这些算法，在来自假宇宙的假图像上测试它们是有用的，看看算法是否能正确地推断出有意印记的属性。这些有特色的假图像马赛克是为了模仿美国宇航局“每日天文图片”（APOD）上出现的图像而制作的。225张图片中只有一张是真实的——你能找到吗？这些老练的骗子通过访问他们的ThisIsNotAnAPOD网页或Twitter feed，提供了个人伪造的APOD图像。然而，对于校准和理解我们遥远的宇宙更有用的是假星系——其中的一个样本可以在他们的thisisnotagaly网页上看到。天体物理学家：浏览天体物理学源代码库中的2,600多个代码

Why would you want to fake a universe? For one reason -- to better understand our real universe. Many astronomical projects seeking to learn properties of our universe now start with a robotic telescope taking sequential images of the night sky. Next, sophisticated computer algorithms crunch these digital images to find stars and galaxies and measure their properties. To calibrate these algorithms, it is useful to test them on fake images from a fake universe to see if the algorithms can correctly deduce purposely imprinted properties. The featured mosaic of fake images was created to specifically mimic the images that have appeared on NASA's Astronomy Picture of the Day (APOD). Only one image of the 225 images is real -- can you find it? The accomplished deceptors have made available individual fake APOD images that can be displayed by accessing their ThisIsNotAnAPOD webpage or Twitter feed. More useful for calibrating and understanding our distant universe, however, are fake galaxies -- a sampling of which can be seen at their ThisIsNotAGalaxy webpage.
