Let me remind you guys that "just 20 light years" = roughly 200 trillion kms. At the speed of voyager 1, it takes roughly 1600 yrs to travel 1 trillion kms. 200 trillion kms would take 320,000 years to reach there. Even if you increased the speed of voyager 1 by 10 times, it would still take 32000 years to reach. We really need to up the speed by a factor of 10000 before we can get anywhere close to human lifetime achievable travel times.
