Astronomers have spotted and weighed a tiny galaxy located 6 billion light-years away, or nearly halfway across the universe.
Dubbed SDSSJ0737+3216, the just discovered galaxy is 100 times lighter than our own Milky Way and is the smallest galaxy ever identified at that distance. It is about half the size and approximately one-tenth the "weight" of typical small galaxies found closer to Earth.

By "halfway", the astronomers are referring to the size of the OBSERVABLE universe. The physical universe, which if this estimate is accurate is nearly 20 times the size of the observable universe, is roughly 2.7 times larger in radius than the 13.7-billion-light-year observable sphere: about 37,000,000,000 light-years in radius.

Of course the Universe has a limit. What moron is suggesting that it is infinite. Its about 15 billion light years across. What's infinite about that?
