This is the only question in the entire post. Everything else is a speculative rant.

I know, I forgot my '/rant' at end of the post, but I WAS ASKING about the planets past pluto.

I've always wondered how exactly steel is made. I know that it is an alloy. I know it is a mixture of mainly iron and carbon (with a few other elements). What I don't know, is how steel would be made. Let's say, in the form of a blacksmith forging a steel sword with medieval methods.

Is carbon and iron both mined separately and then mixed whenst they are heated into molten liquid (is that even possible)? Is the carbon already in the iron ore, and then made more prevalent when impurities are removed from the metal during the forging process? Or, is the carbon somehow absorbed into the metal from the air (this one sounds ridiculous even to me)?

Eris, and an explanation of what a dwarf planet is. We know of or have evidence of additional dwarf planets or solar bodies beyond Neptune. (You can see some of their names—practical or boring—in the article).

Hell is opposite of Heaven which is below the Universe.

We know nothing about this, scientifically. Of course. It's a subject taken on faith.

Most scientists agree with you. Of course, many, like Stephen Hawking, expect encountering them would not end well for us.

There are some good videos on YouTube! Some are much shorter and discuss the subject in more general terms. :)

Yes, I actually looked it up, after I asked the question. I waded through a lot of stuff, and wondered if I could get a even better explanation here. I'm still confused on how the carbon and iron are mixed though.

Also learned that steel has been around for much longer than I originally thought.

Caveat that I have no professional knowledge relevant to this subject, but alloys are basically combining two or more melted metals and allowing them to cool. That's a dramatic oversimplification as the amounts, temperatures, and time periods (e.g. cooling time and rate) are important to the process, and in some cases chemicals are used to imbue certain properties or address certain concerns. There may be multiple stages to a process. Specifics, in many cases, are regarded as trade secrets.

So the best answer I can give to the process is that they're melted together and cooled through a process appropriate to the substances involved and the desired end product.

Here is some more information on carbon steel.

I do know what an alloy is (like bronze: copper and tin), but thank you for the help James. I appreciate it.

I recommend PMing our infrequent member Aaron K. I know that he has a notable interest in weapons and I think that includes how they are made.
