Interstellar Travel
Voyager 2 has finally reached beyond the bounds of our solar system. It has gone 11 billion miles, requiring 41 years to do so. I'm 70. I was 29 years old when it launched in 1977. Its maximum speed: 35,970 mph.
The good news: Voyager 2 is now in interstellar space.
The bad news: To travel a total of one light year (~6 trillion miles), Voyager will need to keep on truckin' for another 500 x 41 = ~20,500 years. That's just to make it one light year away.
The closest star to our sun is Proxima Centauri, which is a mere 4.22 light years away. So, at Voyager 2's speed, reaching the closest star would require 86,510 years, which is easily 4 times longer than the entirety of human civilization so far. That's just our closest neighbor within our own galaxy.
Want to leave the Milky Way galaxy--intergalactic travel? Forget about it. I can't do the math. Science fiction is better.
