How Big is the Universe?
For some reason people have recently suggested that the universe might actually be a lot smaller than we think...
After all, why would God create all those "out of reach" stars for no real reason?
And aren't the stars supposed to fall down on the earth anyway?
And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
- Revelation 6:13 (KJV)
But on the other hand, there's clearly quite a lot of data that suggests the universe is BIG.
For example, check out the Cosmic Microwave Background of the universe.
According to this data, we're only a small dot in the vast expanse of the universe.
And also check out the largest picture ever taken by the Hubble telescope.

Some people have estimated that there are 100 billion galaxies each having 100 billion stars.
And God knows them all by name!
He telleth the number of the stars; he calleth them all by their names.
- Psalms 147:4 (KJV)
Interestingly enough, God only ever mentions creating the stars casually.
And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
- Genesis 1:16 (KJV)
Infinity
If I look inward I can see myself, cells, molecules, atoms, quarks, etc.
So clearly infinity is the hallmark of the Creator here.
If there is infinite detail looking inward, maybe there is also infinite detail looking outward.
If I look outward I can see myself, Earth, solar system, stars, galaxies, the universe, etc.
What is "infinite" for us, might actually be quite "easy" for God to do.
Conclusion
So yeah, who knows, maybe one day we get to go there. How awesome would that be? 
But then again, maybe they're just lights in the sky.
