Is Our Universe Infinite

For years scientists theorized about whether or not our universe is infinite. Unfortunately with modern science we cannot give a definitive answer however we can speculate. 

One speculation supports the theory that the universe is finite. If the universe is in fact limited then that must mean there is a point when the universe stops. So does that mean at a certain point we simply hit a wall? Not exactly. The running theory is comparative to an ant trapped in a spherical ball, the ant could travel in any direction and not notice when it passes it's starting point. Same conceptapples to our universe, if we travelled to the far reaches of the universe we would eventually reach the point where we started. 

In summary, though we do not know whether the universe is infinite or not it is still fun to speculate with theories and speculations.
