The universe is actually flat.
Not true! 1 its a theory that it may be but even in the theory it is not flat, for it to be flat the critical density and the actual density would have to be identical. Even in the theory they are quite different numbers. The sheet of paper would have to be about 2 inches thick which breaks the definition of flat, something that is flat has .1% depth when compared to its length and width, by Nasa's terms. They have another theory where its the same shape as a saddle and that seems to be the one they like most.

Side note, the universe has arms which contain a large quantity of the matter in the universe while the "body" is relatively low in the amount of matter it contains... by comparison.
Yes you are correct. The universe could be flat, which is such a strange idea to me that it suck in my head as the actual shape.

And random fact: Kleenex was originally made from components of Kotex pads. The '-ex' in Kleenex comes from Kotex.
I think you are missing what "flat" means in this context, flat in terms of universe means that (and now we are going into 4d geometry and i don't know the technical terms) if you imagine all of 3d space to be a surface then in 4 spatial dimensions the universe is flat. So the flat, saddle shape etc. are simply analogies to geometry we can picture

Anitediphobia: The fear that somehow, somewhere, a duck is watching you.

The fun fact that you eat about 8 or so spiders a night is not actually a fact, but a falsehood perpetrated by a scientist for an experiment to see how quickly information travels around the world.

"Magic numbers" is an actual technical term in nuclear physics. These magical numbers are the numbers of nucleons that make up extremely stable nuclei. Nuclei with more or less nucleons are less stable until the next magic number is reached.

Water expands when frozen. This is due to the structure of the H2O molecules that causes them to have intermolecular bonds strong enough to form a sort of crystal structure when the temperature becomes low enough.

Lukewarm water freezes faster than cold water. While apparently a fact I do not know the background behind it, nor do I quite believe it is a fact, but I thought I'd share it.

Start from any page in Wikipedia. Click the (I think) first link in that page, and every subsequent page. You will eventually end up on the philosophy page.

All that I could come up with at this time. I'll see if I can't recall more later ;)
Just tried the wikipedia thing, i got stuck in a loop which doesn't include philosophy, sorry :p

Jack Churchill. No relation to Winston. He was a member of the original Commando corp established in WW2. He is the only soldier of the war to be credited with a kill by an arrow. He also carried a claymore sword as well as the bow.
There should be a Pantheon of Badassery, in which this man would hold a place of high honor.
Too tired to look for him myself, but maybe you'll find his name in [a href="http://badasshistory.com/list.html"]here[/a]
Indeed, this is a fine memorial, but I still think there should be some sort of corporeal building devoted to such lords utter awe.

Siping, the wavy lines cut into the soles of boat shoes to avoid slipping on wet surfaces, was originally designed by a guy who was working in a slaughterhouse and was sick of slipping on the blood.

Lake Taupo, the largest lake in New Zealand is in fact the caldera of a massive volcano.

The lake was formed after the Oruanui eruption, the worlds largest in 70000 years with a Volcanic Explosivity Index of 8 (the highest).

It's last major eruption was around 1800 years ago which may have turned the sky red over Rome and China.

Here's a useless factoid, LEGO was originally designed not as a toy but as a cheap prefabricated building material to rebuild Europe after World War II (at a much larger scale obviously).

Also, coconuts kill more people each year than sharks.

And if you Google "recursion" it will ask if you meant "recursion".

I have a few:

You are the centre of the observable universe. The universe itself is expanding, but it has no edge.

A Great White Shark's liver is so big it folds over three times, it's skin is essentially made of teeth (or are it's teeth essentially made of shark skin?)

A giraffe has valves in it's neck that close when it leans down for a drink, otherwise the blood pressure rushing to its head would kill it. It has the same amount of neck vertebrae as we do.

If you go to google, type "find chuck norris" and hit "I'm feeling lucky" it'll tell you not to look for him.

Here's a fun one, what colour is the sun? If you said yellow you just failed. Think of what happens to something when it becomes really, really, REALLY hot. It becomes white right? That's where the expression 'white hot' comes from.

Well the sun is so hot it fits that description perfectly, it's actually a giant white ball of flame. We only see it as yellow due to the influence of our atmosphere.
