Immensity of Space
For the better part of recorded history, Earth was thought to be the stationary center of the universe and the ancient wise men believed there were only 5,119 stars. The constellations were named and filled with colorful legends. Without a telescope the stars seemed to be just twinkling points of light that move across the night sky. Now we know when we look at the heavens that what we once thought were just single stars are often really a gigantic spiral of stars called galaxies.
A galaxy is like a colossal island in space made up of gas, dust, and millions of stars. On clear nights we see the spiral edge of our own galaxy called the Milky Way. Our Sun is just one small star in a pinwheel containing about a hundred billion blazing suns aligned in the form of a disk. And that’s not counting the planets that could be orbiting around these stars. Recent research indicates that there are billions of galaxies in our universe.
A few years ago the Hubble Telescope took a picture of a small spot of sky near the Big Dipper. To give you a better idea of how big this area was, it was about the size of a dime held 75 feet away. In that tiny dot of sky scientists counted over 1,500 galaxies! Take that number times the volume of space in every direction and you would calculate that there are hundreds of billions of galaxies with billions of stars in each galaxy. Wow!
The distance of these galaxies are measured in light years. Keep in mind one light year is the distance you would travel if you could ride a beam of light 186,000 miles per second for 365 days. Our home, the Milky Way, is some 30,000 light-years across. That means you would have to travel the speed of light 30,000 years to cross just our galaxy! And you still wouldn’t have even left our front yard. For example, if you wanted to visit the Andromeda Galaxy you would have to travel over the speed of light for over 2.4 million years.
When we consider the God who made all of this, we can only say, “How Great Thou Art!” It is almost inconceivable that the God who made the infinite cosmos wants to dwell with us. “What is man that You are mindful of him, and the son of man that You visit him?” (Psalm 8:4).
KEY BIBLE TEXTS
When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained; Psalms 8:3What is man, that thou art mindful of him? and the son of man, that thou visitest him? Psalms 8:4
