I don't believe it's possible to see the outer perimeter of the universe with the telescopes we have today. and the universe is ever-expanding, which would make it rather difficult. and just because there isn't anything to see, doesn't mean there isn't anything, just that whatever you're looking at reflects light very poorly (like Pluto for instance) or that there isn't anything to provide light. everything I just wrote may be completely wrong. Good question, though.

I'm not sure what you're asking, so I'll give you what I've got. Pick the most empty region of sky you can, and point a big telescope at it for a long time. The telescope picks up galaxies in the gap that were too faint to see before. But these galaxies were formed a long time in the past because their light took that long to reach us. If we could look further, we'd see the first ever galaxies being formed. Beyond that we'd be looking back in time to a point where the universe was a scalding hot soup of atoms. The light from this soup has been stretched by the expansion of the universe and can be detected with microwave instrucments. It is called the cosmic microwave background radiation. This is as far as we can see because before that the universe wasn't transparent. So if there was an EDGE or PERIMETER to the universe, it would be beyond the region we can physically see. No telescope can see it as it is receding from us faster than the light leaving it - that light would never reach us. Currently scientists are generally in favor of the simplest explanation, which is that there is no edge or perimeter. If we could see it, it would go on for ever.

I'm no expert. What you have described sounds like it could be true. They could mean "observable" universe, in which case the most distant viewable objects are indeed on the outer perimeter. Lets face it though, if the universe goes on to infinity, how do we know for sure that ours was the only "Big Bang"?

1) We actually can see stars or galaxies in all directions, but what does it mean exactly? "no direction of observation seems different from any other; each region of the sky has roughly the same content" 2) "The Universe is very large and possibly infinite in volume; the observable matter is spread over a space at least 93 billion light years across. For comparison, the diameter of a typical galaxy is only 30,000 light-years, and the typical distance between two neighboring galaxies is only 3 million light-years. As an example, our Milky Way galaxy is roughly 100,000 light years in diameter, and our nearest sister galaxy, the Andromeda Galaxy, is located roughly 2.5 million light years away. The observable matter is spread uniformly (homogeneously) throughout the universe, when averaged over distances longer than 300 million light-years. However, on smaller length-scales, matter is observed to form "clumps", i.e., to cluster hierarchically; many atoms are condensed into stars, most stars into galaxies, most galaxies into clusters, superclusters and, finally, the largest-scale structures such as the Great Wall of galaxies. The observable matter of the Universe is also spread isotropically, meaning that no direction of observation seems different from any other; each region of the sky has roughly the same content. The Universe is also bathed in a highly isotropic microwave radiation that corresponds to a thermal equilibrium blackbody spectrum of roughly 2.725 Kelvin. The hypothesis that the large-scale Universe is homogeneous and isotropic is known as the cosmological principle, which is supported by astronomical observations."

Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction—that is, the observable universe is a solid sphere (a ball) centered on the observer, regardless of the shape of the universe as a whole. The actual shape of the universe may or may not be spherical. However, the portion of it that we (humans, from the perspective of planet Earth) are able to observe is determined by whether or not the light and other signals originating from distant objects has had time to arrive at our point of observation (planet Earth). Therefore, the observable universe appears from our perspective to be spherical. Every location in the universe has its own observable universe which may or may not overlap with the one centered around the Earth. The word observable used in this sense does not depend on whether modern technology actually permits detection of radiation from an object in this region (or indeed on whether there is any radiation to detect). It simply indicates that it is possible in principle for light or other signals from the object to reach an observer on Earth. In practice, we can only see objects as far as the surface of last scattering, before which the universe was opaque to photons. However, it may be possible in the future to observe the still older neutrino background, or even more distant events via gravitational waves (which also move at the speed of light)." Source and further information: http://en.wikipedia.org/wiki/Observable_Universe 4) "After 10-6 seconds, the early universe was made up of a hot plasma of photons, electrons and baryons. The photons were constantly interacting with the plasma through Thomson scattering. As the universe expanded, adiabatic cooling caused the plasma to cool until it became favourable for electrons to combine with protons and form hydrogen atoms. This recombination event happened at around 3,000 K or when the universe was approximately 379,000 years old. At this point, the photons scattered off the now electrically-neutral atoms and began to travel freely through space, resulting in the decoupling of matter and radiation. The color temperature of the photons has continued to diminish ever since; now down to 2.725 K, their temperature will continue to drop as the universe expands. According to the Big Bang model, the radiation from the sky we measure today comes from a spherical surface called the surface of last scattering. This represents the collection of points in space at which the decoupling event is believed to have occurred, less than 400,000 years after the Big Bang, and at a point in time such that the photons from that distance have just reached observers. The estimated age of the Universe is 13.7 billion years. However, because the Universe has continued expanding since that time, the comoving distance from the Earth to edge of the observable universe is now at least 46.5 billion light years" Source and further information: http://en.wikipedia.org/wiki/Cosmic_background_radiation#Features
