I am at a road block because I have some questions with good answers and I don't want to delete them what else can I do?
It looks like you have triggered our automatic question ban. The algorithm that decides whether you can post a particular question is not public, so there's not much we can advise you that you can't get from reading this or this. But it's worth calling attention to a couple of things.
Having low-scored questions in your history makes it more likely that you'll be prevented from asking more questions in the future.
Having deleted questions in your history also makes it more likely that you'll be prevented from asking more questions in the future. Resist the temptation to delete your poorly-received questions. It looks like the ones you have asked so far are safe from the roomba.
It's a very good sign that you are actively inquiring about how to improve your questions, and your most recent question has been well-received. Progress! But it's worth highlighting a particular bit of advice from one of your answers there:
All of this takes time, hence: patience patience patience.
In all honesty, encouraging you to edit your questions and wait is the entire point of the automatic post bans. As a diamond moderator, I have a little information about your post-ban status, and it looks like you've been blocked from asking several times already. Take the hint and wait. Take your draft question, save it somewhere on your own computer, and sit on it for a while. If you waited a day before trying to post last time, wait two days the next time; if you waited two days and still got blocked, try waiting four days. It's easier to wait if you decide in advance when you'll try to ask again.
While you're waiting, if you find yourself thinking about your question, work on improving your draft. Spend some time searching other parts of the internet, and modify your question to be clearer about what you already know, what you've found during your searches, and what you're still confused about. Include in your draft links to the things you've found that are useful or confusing. Maybe you'll even answer your own question before you get around to asking it!
The other thing I'd advise you do while you're waiting is to read. If you have questions about stellar evolution, spend some time reading in astronomy. If you have questions about how sound works, spend some time reading in acoustics. Look for questions that interest you and that have been well-received, where both the questions and the answers are clear. And compare the way that those questions are written to the draft(s) of your own question(s) that you're waiting to be able to post. Time spent reading is time spent learning how to write.
