So two scientists invent a machine that can travel to other dimensions... After much calibrating and testing and preparing, the scientists hop aboard their creation and activate it. There is a blinding flash of blue light and in an instant the scientists are sitting in the middle of a grassy field. There is no sign of their lab...or really anything familiar at all. The scientists cautiously leave their machine and explore the field. However, the only thing they find there is a single horse peacefully grazing. After some discussion the scientists decide to explore the surrounding area, but only ever find more horses. Indeed the horses seem to be the only form of life in the alternate dimension they've traveled to. Noting this, the scientists examine the horses carefully but cant find anything unusual about them individually. They seem like they'd be perfectly at home on Earth. However, strangely, every single horse is female. There isn't a stallion to be found. Perplexed by this, the scientists return to their machine and make preparations to head back home. Shrugging at the horses that surround them, one scientist says to the other: ""I guess we've traveled to a mare-allel universe.""
