God said in Isaiah 55:6-9, "Seek ye the LORD while he may be found, call ye upon him while he is near: Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon. For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts." So the question occurred to me, how high are the heavens above the earth?
Let me see. At 186,282 miles per second, (the speed of light), there are 5,878,612,843,200 miles in one light year. (186,282 x 60 seconds x 60 minutes x 24 hours x 365.25 days). That is how far light will travel in one year at 186,282 miles per second. Scientists tell us that the universe is about 13.7 billion light years old. So that means that the (so called) Big Bang happened about 13.7 billion light years ago. 13.7 billion light years equal 8.05354475 × 1022 miles. Eh? How many zeros are there in 13.7 billion light years? Or, for that matter, how many zeroes in one billion light years? According to http://www.ask.com/math/many-zeros-one-billion-3c3dfef9acb6436d#, there are 9 zeros in one billion. So one billion light years would be 1,000,000,000 miles, or one thousand million miles. 13.7 billion light years would be 13.7 thousand million miles. (I think, it sort of boggles the mind).
For that matter what is the nearest star to our sun? For the answer to that question I went to the website address, http://www.skyandtelescope.com/astronomy-resources/far-closest-star/. According to this website, the nearest star is actually three stars which "are bound together by gravity." Of those three, the first two, called Alpha Centauri A and B, are the brightest. The other one called Proxima Centauri is only (about) 4.24 light years or 24,925,318,455,168 miles from our sun, (5,878,612,843,200 x 4.24). A wee bit far for a day trip.
So to cut to the chase, the known universe is about 13.7 billion light years old according to the last scientific estimate I saw. (No one knows for sure). How high are the heavens above the earth? The Bible says in Ecclesiastes 3:10-11, "I have seen the travail, which God hath given to the sons of men to be exercised in it. He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end." The Apostle Paul said in Romans 11:33, "O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!" So as much as the physicists would like to know the secrets of God's creation, they will never find out.
Friend of mine, if you want to be truly saved when Jesus returns, the Bible says in Isaiah 1:18, "Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool." If you will repent of your sins turning to the Lord Jesus, be baptized in the name of the Lord Jesus Christ, "for the remission of sins," God has promised to give you His Holy Spirit, just as He gave those early believers on the Day of Pentecost. (See Acts 1:8 and 2:38-39) You don't have to understand God's ways for the Bible says in Isaiah 35:8b, "And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein."
