XKCD: What if ALL the sun’s power was focused in one place?

The dire fate of the earth seems pretty obvious here. I'm more interested in what would happen to the sun in that scenario. If all of its radiating energy was focus down to a narrow beam pointing in one direction, wouldn't that push it in the opposite direction?

That depends on how you get the light to focus.
 

Now explain how Starkiller Base kills planets hundreds of light years away, while said destruction is visible in real time from other planets tens of light years away.

No-prize: Starkiller base is not a giant space laser. It is a giant, Force-driven hyperspace weapon. The "visible" phenomenon is essentially a Force-vision driven into the minds of every sentient being in the (very large) area.

Huh. That's a good way to think of it. Never thought of it that way before.
 

The Strange New Worlds season three finale specified that they were firing both ships' phasers in tandem at that space magic-infused stele on Skygowan to match the energy output of a star, yet we got no plasma holocaust at all. Now the episode just feels half-baked for one more reason.

To be clear I'm not complaining they didn't accidentally obliterate the Skygowans and several main characters, I'm complaining that this episode (and perhaps some other somewhere in the franchise) just casually established that each starfleet ship's phasers can match half the energy output of a star, when that is clearly orders of magnitude too high to have not had consequences throughout the franchise, seemingly all just to make for simple dialogue in one scene where they had to explain the insane energy they required to activate the space macguffin.
