Thanks for that video. Please listen.

In the Bible God is represented as light. Speed of Light is constant? Yes. Ironically in the Bible God is known to be constant and never changing.

Another thing the video pointed out was that going so fast would make life slow down for others. God is outside of time and thus we experience thing much slower than he does. That's why the Bible mentions that 1,000 years to us is like a day to God.
