Now for some of you, the concept of a light year is familiar. But that's the point. It sounds familiar and tame to say that Alpha-Centauri, our nearest star, is 4.3 light years away. But if we add the zeros, we truly see how isolated we are, circling our Sun in our corner of the Milky Way. Alpha-Centauri is 25,000,000,000,000 miles from Earth.
Now consider that the most distant objects that we can see without a telescope are about 1.75 million light years away. There we go again -- big numbers. But that's a big number of something that already is a gigantic number. And that doesn't even take into consideration what the Hubble Space Telescope can see, distances of over 7 billion light years away. We are just now seeing light that left those distance realms in the early days of the universe. The universe is indeed a very, very big place.
