The Universe Is Much Bigger Than We Can See

We know that the universe is much bigger than the portion we can see. The fact that the earth looks so flat told Columbus that it must be very big. But just like Columbus whose observations were bounded by the horizon, our observations are also bounded,. Most of it is out beyond our telescopes. For all we know it could be very different, doubted, very, very distant scales. Perhaps the answer is we live in the kind of places where life is possible. That would answer a lot of questions about why our universe seems so fine-tuned for our own existence.
