There are a number of different theories, but the below article shows that science is leaning towards the idea that the universe is flat! This is another deep topic and can be hard to wrap your mind around.
What I find interesting is that the Bible compares the universe to a scroll, which of course is flat, that in the end will be rolled up. This is stated in Revelation when it is stated, "The sky receded like a scroll being rolled up, and every mountain and island was moved from its place." It is also mentioned in Isiah when it is stated, "And all the host of heaven will wear away, And the sky will be rolled up like a scroll; All their hosts will also wither away As a leaf withers from the vine, Or as one withers from the fig tree."
