Rocket motor help.

I live in Texas, and the weather has been miserably hot, so I asked Alexa "how could I shut the sun down".
She suggested dumping several trillion tons of iron into the sun.
What size rocket motor would I need for that?

All at one time? or in several smaller shots?

I'm simultaneously amused and disturbed that you actually got a more or less correct answer to that question.

Probably need to have it spread fairly evenly.
Many rockets, at least on final approach.

Wouldn't be easier & cheaper to just build a massive sun shield.. and put it into orbit..

Alexa? You need to start talking to smarter AI bots.
Looks like the rocket would need to weigh 27,180,000,000,000,000,000 kg assuming we can make some motors with uber-ISP.




Also, after you get done building the rocket you might want to check on this...

As many rockets I lost as a kid flying on a C6-5, one of those should be plenty.

Yes, but not as much fun.

Stop spoiling my fun with reality.

All at once, just to make it more ridiculous.

Ok. Let's keep playing...

Instead of a giant rocket to lift 3 trillion tons of iron from earth, you could just push Mercury into the sun. It looks like Mercury has about 2.54 x 10^20 tons of iron. A much smaller rocket could be used to give Mercury a shove.

So, does that mean that Mercury would function as a fire extinguisher when our sun goes nova?

Or the fuze for an Earth-ending thermonuclear explosion.

What about a few rockets & robots to attach & steer some asteroids into the sun? Getting to them might be easier (less fuel)

Astrophage?!?!

For Mercury to have any effect it'd have to be moving at near-relativistic speed. So I guess we're back to that C6-5 motor...
