That's not true.
(1) We can launch a rocket that has a payload that hits the sun: it's just costly to do because the rocket starts out orbiting the sun, so we would have to expend delta-v to neutralize the tangential component of the initial velocity.
(2) If you are in a space ship heading towards the sun, it is easy to hit the sun as long as you can steer, and even if you can't steer, if you are heading squarely at it and no planet gets near you to change your velocity, you will hit it.

- dang 2y agoCan you please make your substantive points without swipes? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html. Your comment would be just fine without the first sentence.
- EnPissant 2y agoPretty sure you (or someone else) decided to pour over my post history looking for violations after I posted this: https://news.ycombinator.com/item?id=43794576 https://news.ycombinator.com/item?id=43794576 This 3 day old comment was not flagged until just now, what I said is not a swipe at all.
- EnPissant 2y agoCorrect link: https://news.ycombinator.com/context?id=43796297 https://news.ycombinator.com/context?id=43796297 Somehow, I can't edit a 5-minute-old post.
- dang 2y ago"You are missing the point" counts as a swipe in the sense that the HN guidelines are using the term. Please edit them out in the future. They just add acid to the threads, and you don't need them. Looking over account histories is standard moderation; of course we do that.
- EnPissant 2y agoClearly I am being targeted by dragonwriter for posting something in another thread that they don't like.
- dragonwriter 2y agoLiterally, until just now (checking your comment history to see if possibly we had interacted elsewhere that I had forgotten), I hadn't seen or read any of your posts outside of this thread. Not sure how you got from me responding to two of your posts in this thread that I was "targeting" you for something in some other thread.
