The Hitchhiker’s Guide to the Galaxy may have given us the answer to the meaning of life, but it did not explain everything about the universe. As science has progressed, our explanations for the universe have grown increasingly complex, from the early belief in four elements, to string theory, superstring theory, and the Higgs-Boson, the so-called “God particle.”
What follows is a look at 10 of the craziest theories about our universe that are now readily accepted. While science in its purest sense never considers anything to be 100% true (there is always the possibility something could come along and disprove a theory) there are a few ideas which are currently considered probable.
In the scientific community, a theory becomes accepted when empirical evidence becomes overwhelmingly supportive. An example is the “Giant Impact Hypothesis,” which suggests the moon was formed when a planet about the size of Mars collided with the earth. While it is not yet universally accepted, there is an increasing body of evidence which makes it ever more acceptable as a hypothesis.
All the ideas we will look at are generally accepted as fitting the evidence. At the time they were proposed, however, they were considered pretty “out there.”

Top 10: Crazy Theories About The Universe That Were Proved True
Getting Started
OK, lets get straight into it. Here, you will learn just how easy it is to create a web page. In fact, by the time you've finished with this web page, you will have created your own web page!
When you create a web page you will usually do something like this:
- Create an HTML file
- Type some HTML code
- View the result in your browser
- Repeat the last 2 steps (if necessary)
Creating a Webpage
OK, let's walk through the above steps in more detail.
-
Create an HTML file
An HTML file is simply a text file saved with an .html or .htm extension (i.e. as opposed to a .txt extension).
- Open up your computer's normal plain text editor (this will probably be Notepad if you're using Windows or TextEdit if you're using a Mac). You could use a specialized HTML editor such as DreamWeaver or FrontPage if you prefer.
- Create a new file (if one wasn't already created)
- Save the file as html_tutorial_example.html
-
Type some HTML code
Type the following code:
- Navigate to your file then double click on it
- Open up your computer's web browser (for example, Internet Explorer, Firefox, Netscape etc).
- Select File > Open, then click "Browse". A dialogue box will appear prompting you to navigate to the file. Navigate to the file, then select "Open".
-
Repeat the last 2 steps until you're satisfied with the result
It's unrealistic to expect that you will always get it right the first time around. Don't worry - that's OK! Just try again and again - until you get it right.

Explanation of code
OK, before we get too carried away, I'll explain what that code was all about.
We just coded a bunch of HTML tags. These tags tell the browser what to display and where. You may have noticed that for every "opening" tag there was also a "closing" tag, and that the content we wanted to display appeared in between. Most HTML tags have an opening and closing tag.
All HTML documents should at least contain all of the tags we've just coded and in that order.
The next lesson goes into a bit more detail about HTML tags.
HTML Font Code
Here are some HTML font codes that you can copy/paste straight into your website or MySpace page. Once you've pasted the code, you can change the values as required.
TIP: You can make it easy on yourself by using the text generator.
Quick Example
The following font code sets common properties such as font size, line height, font family, and font color. Here are some more colors to choose from.
The above code results in this:
This font is 14pt, the line height is 20pt, it's color is orange, and the font family will be 'Garamond'. If the user's computer doesn't have 'Garamond', it will use 'Georgia'. Failing that it will use the default 'serif' font on the user's computer (this is often 'Times' or 'Times Roman' - just leave it as 'serif'). You can also specify bold text and italics if you wish!
Font Family
If you only want to specify the font family, you can use the 'font-family' property:
The above code results in this:
HTML font code is done using CSS.
Font Size
If you only want to specify the font size, you can use the 'font-size' property:
The above code results in this:
HTML font code is done using CSS.
Color
If you only want to specify the font color, you can use the 'color' property (more colors):
The above code results in this:
HTML font code is done using CSS.
Bold
You can make your font bold by using the 'font-weight' property:
The above code results in this:
HTML font code is done using CSS.
If you only want to bold some of the text inline, you can use the HTML 'span' tag:
The above code results in this:
You can bold parts of your text using the HTML 'span' tag.
Italic Text
You can make your text italic by using the 'font-style' property:
The above code results in this:
HTML font code is done using CSS.
If you only want to make some of the text italic, you can use the HTML 'span' tag:
The above code results in this:
You can make some of your text italic using the HTML 'span' tag.

About HTML
HTML, which stands for HyperText Markup Language, is a markup language used to create web pages. The web developer uses "HTML tags" to format different parts of the document. For example, you use HTML tags to specify headings, paragraphs, lists, tables, images and much more.
HTML is a subset of Standard Generalized Markup Language (SGML) and is specified by the World Wide Web Consortium (W3C).
What do I need to create HTML?
You don't need any special equipment or software to create HTML. In fact, you probably already have everything you need. Here is what you need:
- Computer
- Text or HTML editor. Most computers already have a text editor and you can easily create HTML files using a text editor. Having said that, there are definite benefits to be gained in downloading an HTML editor.
If you want the best HTML editor, and you don't mind paying money for it, you can't go past Adobe Dreamweaver
. Dreamweaver is probably the best HTML editor available, and you can download a trial version for starters.
If you don't have the cash to purchase an editor, you can always download a free one. Examples include SeaMonkey, Coffee Cup (Windows) and TextPad (Windows).
If you don't have an HTML editor, and you don't want to download one just now, a text editor is fine. Most computers already have a text editor. Examples of text editors include Notepad (for Windows), Pico (for Linux), or Simpletext/Text Edit/Text Wrangler (Mac).
- Web Browser. For example, Internet Explorer or Firefox.
Do I need to be online?
No, you do not need to be online to create web pages. You can create web pages on your local machine. You only need to go online when you want to publish your web page to the web - this bit comes later.
The next lesson will show you how to create a web page in less than 5 minutes.
