Then God said, “Let there be lights in the firmament of the heavens to divide the day from the night; and let them be for signs and seasons, and for days and years; 15 and let them be for lights in the firmament of the heavens to give light on the earth”; and it was so. 16 Then 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. 17 God set them in the firmament of the heavens to give light on the earth, 18 and to rule over the day and over the night, and to divide the light from the darkness. And God saw that it was good. 19 So the evening and the morning were the fourth day. Genesis 1:14-19
Not that Albert ever intended to, but his theory of relativity gives us a very good explanation of a question that dogs folks like me who believe that the earth is only about 6000 years old. How is that starlight from billions of light years away is visible to us if the earth is a mere 6000 years old? That light wouldn’t be here yet!
Ken Ham discusses an explanation for that based on science in his The New Answers Book 1.
Einstein proved that time is relative; it moves faster the farther one moves away from a gravity well (planet, star, moon, etc.). This is called “gravitational time dilation.” Conversely, time slows the closer one gets to the center of a gravity well. Time passes faster for people living on a mountain than those living in a valley. Technically, assuming you’re standing more than lying flat, your head ages more quickly than your feet.
There is also “relative velocity time dilation.” Essentially, the faster you go the slower time goes. If someone goes near the speed of light, they will age more slowly than someone not moving at all.
According to an article on time dilation on Business Minder, these two types of time dilation can happen at the same time. For example, astronauts experience countering effects of both while in orbit on the International Space Station. Because they orbit 260 miles above earth, time should slow for them. But they are also travelling at 5 miles per second. These opposing time dilation effects do not cancel each other out. Velocity has a bigger effect than gravity, so they age more slowly than people on earth.
However, satellites travel slower in higher earth, geosynchronous orbit, so time moves faster, affected more by gravity than speed.
Light moves very fast – about 670,616,629 – so it experiences relative velocity time dilation. Time goes incredibly slow for light. Ken Ham writes, “…according to Einstein’s relativity, light does not experience the passage of time, so the trip would be instantaneous.”
Ultimately, this is a theory which fits known facts and is not one that can be tested. At may be that God simply caused light to arrive instantaneously on earth. But we also know that God has created a marvelously engineered universe which runs on laws of physics and biology. It may be that, once again, science provides the answer that supports a young earth!
