*Let Destruction Reign!* How to Win an interstellar War by Kurzgesagt-In a Nutshell 

Yikes! Well on the other hand, the Smorphians just need to listen when human signals of life ends "OK they have done each other" let's see if we can land on the remains.

"maybe they love for thousands of years..." Stop giving them additional advantages! On the other hand, we could subjugate them to a lifetime of Vogon poetry and it would be thousands of years torture. I'm torn.

The construction of a weapon like the the star laser would take more than 42 years. It could take centuries. The longest part would be building enough satellites. 42 years is just how long light takes to get from where they are to where we are and then back again. Also, it would take 42 years regardless of how long they lived, again, the 42 years number is based on how long it would take light to travel there and back. So yeah, it would take much longer than it takes to fix a pothole, that 42 years thing is just how long it takes the weapon to have any effect and how long it would take for the Smorps to notice. It would be like firing a bullet and waiting 42 years before seeing it hit the target. That’s just how long it would take the bullet to get there and for the light to come back and reach our eyes.

Lauren, just smile because why not

The first and third methods have the same issue of having to hit a small moving target from 42 light years distance, an impossible task. The second form of attack runs into a physics issue. As matter (like that missile) approaches the speed of light, it's mass increases enormously to where the closer to the speed of light, the closer it's mass become infinite. Basically it would never get here. I'm not going to lose any sleep over this.
