hey aliciaa, k cha, gayab ajjkal :) Aliciaa, your question cannot be answered in any ordinary statement. This is indeed a deep philosophical question!.. This question has not just captivated you and me, but many philosphers and scientists of ancient and present age. Bruno, one of the greatest philosopher, was burnt alive because of his view on God and the infinite universe. He preached, that God is everywhere, and universe is infinite, and Earth like world are scattered around this universe. He also said, that we will always continually strive for knowledge, eventhough he agreed our knowledge is limited, which can be tuned with the infinite universe. We may suffer because of our limitations but man will be satisfied, while he is continiously searching for the perfect ideal, happiness and these consists in the awareness of one's "fundamental unity with the infinite universe." There are many philosophical ideas about universe and hence, this is one which has made me wonderous! Talking scientifically, our views on universe is limited with physics, because the only way we can measure the size of our universe is by calculating the light of the most distant star and how far it can travel. There might be place in this space where this light cannot travel at all, so hence there we also dont know the definate answer to the size of our limited or unlimited universe. Big bang theory, and theory of finite universe or infinite universe, ( just a year ago, some scientis have drawn a shape of an finite universe,) can never be really observed, maybe not in our lifetime, so these theories are just theories, for us, which we cannot be certain of. so therefore, we do not know if universe has an edge or is it just going and going and going... but me individually, i think universe is infinite and it was created by a creator..
