Warclema

One day, a universe very much like our own, maybe even the same one, had experienced what is called the "Big Crunch", the act of the universe's expansion stopping, and reversing, until the entire universe crushed into a single point in space. As you might imagine, humanity didn't really like the idea of becoming one with the universe by being crushed, so they tried to find a way to escape this fate. In the end, they discovered interdimensional travel, and left their universe.

What they found was a strange world with strange physical laws that were rather hostile to them. Their only protection from the dangers of a set of physical laws that didn't include conversation of energy, gravity, and a few things that went undiscovered due to being taken for granted, was that their travel had left a connection to their old universe. It was a connection that forced the area around it to follow the physical laws of that universe.

Humanity managed to survive in this strange world that they came to refer to as "Warclema".
