Spaces, the Final Frontier

This is the first line in my code. But this is the second?

No, this is the second line because I surrounnded it with paragraph tags.

Is this the third line? Yes. But this is not the fourth line.

This is the fourth line.

The web browser only reads one space in my code. If I want my text to be on the very next line, I would have to code it that way.

The way you code the text to move to the next line is to use the
break tag. The "br" stands for "break" as in the line break. Notice how the next
word is on this line and not the one above? It is because I used a break tag.

Now I will write a paragraph about space. When I looked up space in the dictionary, there were a lot of entries about space. One entry said that space is a blank or empty area. While, another entry said that space is the infinite extension of the three-dimensional region in which all matter exists. The first definition made more sense to me.
