THERE ARE BLOOD AND GUTS EVERYWHERE! Only they are normally inside of people.

"So how many ways can you order all the 52 cards in a pack?

The sum is 52x51x50x49x48....x4x3x2x1 and the answer is roughly:

80,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000" [1]

If alphabet was in any other order then it couldn't be called alphabet in the first place.
A --> Alpha
B --> Beta

I've posted this before, but the first image in this album reminded me of it, so I updated it and am posting it again.

A trillion is a gigantic number. Really, really gigantic, but most people can't truly understand the difference between a million, a billion, and a trillion because those numbers are almost unfathomable.

So instead of using money to describe numbers, I'm going to use time. I fudged some dates or numbers to use major events; forgive me.

• 1 (one) second ago, you started reading this sentence.

• 10 (ten) seconds ago, you were about halfway through my first paragraph.

• 100 (one hundred) seconds ago, you were reading someone else's comment (depending on how this is ranked).

• 1000 (one thousand) seconds ago, if you started browsing reddit, you’ve been here well past the average redditor.

• 10,000 (ten thousand) seconds ago, if you started watching The Dark Knight or The Dark Knight Rises, you'd be ending around now.

• 100,000 (one hundred thousand) seconds ago, you were browsing yesterday's reddit.

• 1,000,000 (one million) seconds ago, if you felt sick from a bad case of the flu, you'd be feeling better around now.

• 10,000,000 (ten million) seconds ago, if you got pregnant, you'd start showing around now.

• 100,000,000 (one hundred million) seconds ago, The Syrian Uprising was in full swing.

• 1,000,000,000 (one billion) seconds ago, President Reagan was halfway through his first term.

• 10,000,000,000 (ten billion) seconds ago, the Salem Witch Trials were happening.

• 100,000,000,000 (one hundred billion) seconds ago, the Trojan War just ended and Helen of Troy is about to commit suicide.

• 1,000,000,000,000 (one trillion) seconds ago, the oldest known cave paintings were being painted.

• 10,000,000,000,000 (ten trillion) seconds ago, Neanderthals had just started wandering the Earth (although some estimates say they were around before then).

• 100,000,000,000,000 (one hundred trillion) seconds ago, Africa collided with Europe to form the Mediterranean Sea.

• 1,000,000,000,000,000 (one quadrillion) seconds ago, South America detached from Antarctica and the Alps started to rise.

if you put your finger in your ear and scratch, it sounds just like Pac-Man.

Edit: I'm so happy i could make so many people put a finger in their ear.

12 is dead wrong.

The electron's drift velocity may be slow, but the electric field propagation is not. Electromagnetic waves travel at the speed of light, it has nothing to do with collisions: They all start moving with the wave, not when the previous electron bumps into it.

16 - "All the planets fit between the Earth and the Moon"

I know this is true because it's been posted on reddit before but... the picture represents the planets in line with the Earth in the middle....

I don't know that I agree with all of these, but am too lazy to do my own research.

If the dinosaur one is accurate does that mean from 20 light years away I could see myself as a kid?

About half of these are lifted from off-hand comments in xkcd what-ifs posts.
