If I am understand correctly a moving mass has more energy than a stationary mass. Mass and energy are two forms of the same thing so more mass is more energy and more energy is more mass.(adsbygoogle = window.adsbygoogle || []).push({});

Suppose we decided to take our (almost) light speed rocket ship and reach the edge of this apparently open universe using ourselves as the preferred frame of reference.

As we reach ever increasing speeds the universe would (from our frame of reference) be moving faster in the other direction.

This means the universal mass/energy in our preferred frame of reference would increase.

But if the universal mass increases ten fold we have a closed universe.

Meanwhile the edges of the universe are receding from us so we must at least maintain a little more velocity then they have to catch them.

So our universe is closed if we try to leave it but open if we stay where we are.

Have I made any errors here?
