The sky is dark at night. That's something we take for granted with no questions asked. But why is the sky dark at night? Hint: It's not because the sun is down.
In a really simple and fun video, Henry Reich, a researcher at the Perimeter Institute in Canada, explains why the light in the sky fades at night. We don't want to spoil it for you, but it involves the ever-expanding universe and physics. But worry not, you don't need to be a science genius to understand the concept.
The video is part of a series of educational videos called Minute Physics, which aim to explain science in an elementary way. The videos have been so successful that Reich has received an offer to join the elite Khan Academy.
To find out the real scientific reason why the sky is dark at night, check out the video above. Maybe it will cure your fear of the dark as well.
Sometimes you need to look at things a litter bit closer than usual to see the humor -- or the harsh realities -- that they really hold.
At Legoland Florida's Miniland USA, this is absolutely the case.
Over the course of two days, travel writer and blogger Raymond Walsh found and photographed a number of unexpected Easter Eggs that are built into the giant Lego structure.
According to Walsh's blog, more than 100 Master Builders from North America, Europe, and Asia worked for two years to complete the Miniland USA attraction. According to the photos he collected, some of them had a very twisted sense of humor.
With the release of the iPhone 5, Apple scrapped the old, reliable 30-pin connector in favor of its newfangled Lightning connector. Millions of 30-pin connector cords will be stranded in households across the world.
These proud workhorses of the iWorld shouldn't be simply put out to pasture. Save the planet by repurposing your noble iPhone cord to one of these completely realistic hacks.
Our texts, emails, tweets and other forms of communication may have shrunken in size, but there is no excuse for poor grammar -- especially punctuation.
A misused or missing comma or apostrophe could completely change your sentence. "Let's eat, grandma" becomes "let's eat grandma" instead. Who would do such a horrible thing to their grandmother?!
National Punctuation Day is Sept. 24. To celebrate raise awareness we've gathered some of the funniest, most unfortunate examples of poor use from around the world. Take a browse though the gallery, and then brush up on your grammar skills here.
Scrollbars help gadget users pinpoint their location in the vast computer sea. Are you at the top of the page or the middle of a document? The trusty scrollbar will let you know.
Twitter user Ivan Listes offers a look back at the history of scrollbars with a simple graphic that probably won't have you pining for the days of clunky red scrollers.

Just one smile can brighten up a room. A smile is a universal symbol: It's one of our first means of communication as babies and requires no translation across cultures. Although smiling may seem like a uniquely human trait, it's not uncommon to see smiles from animals -- or even inanimate objects. Thanks to the proliferation of Internet communication, smiles have even become a part of our written language.
Last week for the Mashable Photo Challenge, we honored the 30th anniversary of the emoticon by asking our readers to submit photos that represented a smile.
