How long would it take to reach the far to edge of observable universe if going at 5 miles per second?

Answer 1

You would never get there. Is this a trick question?

"The Edge" of the observable universe is approximately 45 billion light years away; however, it is expanding. Since light travels at a speed of 186,000 miles per second, you will cover 7200 miles per day in your example. You will need to use all of your resources to survive in our solar system, let alone our galaxy, which is located 100,000 light years beyond us.

You cannot travel at the speed of light; it would take 45 billion years if the universe were in a steady state, which it is not.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
