Light travels at approximately 186,000 miles a second. That is about 6,000,000,000,000 miles a year.
The closest star to us is Alpha Centauri. It is 4.75 light-years away. 28,500,000,000,000 miles.
So, traveling at 186,000 miles a second, it would take us 4.75 years to reach it. The voyager spacecraft [just now exiting our solar system] will take 70,000 years to reach it.
To reach the center of the Milky Way galaxy it would take 100,000 light-years.
Or consider this:
“To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager’s speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!”
The Andromeda galaxy is 2.537 million light years away.
Or this:
“The universe is about 13.7 billion years old. Light reaching us from the earliest known galaxies has been traveling, therefore, for more than 13 billion years. So one might assume that the radius of the universe is 13.7 billion light-years and that the whole shebang is double that, or 27.4 billion light-years wide.”
For all practical purposes, it is beyond the imagination of mere mortals here on planet Earth to grasp just how staggeringly immense the universe is.
As for situating “I” in all of this…?
