It usually goes that either a smaller universe or one in which the speed of light was once faster is desired by fudgedamentals because it permits us to see the light of the stars (obviously a universe created with light in transit would be the work of a liar). Unfortunately both solutions create a cascade of major problems with the whole of science, as those alterations to bring the light of stars and its science into this biblically literal model of the universe pushes the rest of science out of observed reality, and correcting again just makes things worse. Like a line of falling dominoes that spell out "YOU HUMONGOUS TWIT".
The short answer is, a smaller universe complete fucks up gravity and everything relating to it (ie, everything). And since we measure astronomical distances using the speed of light as the standard, increasing the speed of light increases the measured size of the universe, thereby requiring the same travel time as before. Also, the increased size of the universe fucks up gravity etc.
