HWKE, can you just clarify who's question are are you referring to? You replied to potterfan3, CheekyChops and Skreecheeboy prior to my post.
Solid Hydrogen unquestionably exists and my post was not aimed at confirming or refuting this fact. However, I did consider it worthwhile to provide some background information on this topic as someone just might be interested in the information. I'm sorry if you have misread my motives for providing this information.
The problem with the post from Skreecheeboy is that I can't be certain to what temperature the chemistry teacher was referring to. However, I'm sure you'll agree that it's fairly probable that the teacher was aware of the the work of McGrady and his colleagues and hopefully, was aware that Hydrogen is already a liquid at -260 degrees Celsius.
Sometimes on AB, there is every reason for providing a concise, laconic answer to a question. Unfortunately, by the time I came onboard, the question had turned away from the initial question posted by potterfan3 into other matters.
Now probably because I'm a genuine university professor , I have a habit of answering not only the initial question posted here but also any questions or statements that have arisen by other posters in answering the question prior to my own reply. That's me.
Now with this in mind, I hope you'll appreciate that I don't post here to score points. As I stated earlier, my reply diversified deliberately to fit in with the matters raised by the original questioner and others prior to my own post and for no other reason.
I don't doubt that you are correct in your assessment of what the original questioner was asking and it's admirable to confine yourself to the question wherever possible. Yet even you must see that you've diversified yourself in all three of your postings because of what others posted. Clearly, I'm not alone in being unable to confine myself
