Are there any limitations placed on mankind? Some think not. Others believe we lived in an enclosed system designed by God. The Bible says that God created something called the firmament on Day 2 in Genesis Chapter One. This is a massive solid dome of unknown height, width, and composition. In it the Creator placed the sun, moon, and stars. He put waters above and below it. On top of this crystalline-like dome, God’s throne is located.
The firmament serves as a barrier between God’s realm and ours.
O LORD, our Lord, How excellent is Your name in all the earth, Who have set Your glory above the heavens! Psalm 8:1 (NKJV)
Nimrod, according to tradition, was behind the first failed attempt to penetrate this barrier. The tower of Babel was an attempt to “make 
a name” for himself, rather than glorifying God. Tradition says that Nimrod wanted to shoot God with an arrow. Although this is not in the Bible, I think it fits with the depraved heart of man. God cut off this plan by confusing the language of the builders and scattering them over the face of the earth. In case you did not realize it, mankind has not given up on this quest. Every rocket launch is another attempt to breach the firmament.
God placed the earth under man’s authority and dominion, but he reserved heaven for himself.
The heavens are the heavens of the LORD, But the earth He has given to the sons of men. Psalm 115:16 (NASB95)
Heaven is a real place that is reserved for God, the holy angels, and those purchased by the blood of our Lord Jesus. No one from NASA, ESA, or Space X will ever go there with a rocket. Outer space is a hoax. According to the Bible, the sky is the limit.
