How Can You Prove You're Real And Not Some Evil Genius Demon's Figment of Imagination? - VIDEO

Real

How do you know you exist? It's a simple enough question, but the answer is a little more tricky. After all, how do we know we aren't dreaming? Or that some evil genius demon hasn't tricked us into believing that "reality" is "real"?  

A new TED video helps break down these questions of existence - leading us towards Descartes' famous philosophical conclusion: I think, therefore I am.

Everything You Wanted To Know About Earth But Were Too Busy To Ask (In 7 Minutes): VIDEO

Earth1

Ever wondered the exact mineral breakdown of the Earth's crust? Ever wanted a side-by-side size comparison of Mount Everest, the Burj Khalifa, and the asteroid that killed the dinosaurs? Ever wanted to know just how minuscule our time here on Earth has been?

I was not sure I did either, until someone took care of the details and made the perfect little video about "living in a thin, moist layer on a small, wet rock." Produced by YouTube user Kurzgesagt, the 7-minute thrill ride through the Earth's history is full of fun facts and sardonic humor, all narrated in a wonderfully British accent.

Solar Flare Almost Ended Modern Life As We Know It: VIDEO

Extreme Solar Storm

For all of the end times prognostication that occurred in 2012, it turns out that modern life actually was almost completely destroyed that year, thanks to an "extreme solar storm" that sent plasma clouds hurtling from the sun at a rate of 3,000 km/s. Described as a "Carrington event", named after English astronomer Richard Carrington who observed a similar storm in 1859, the storm would have hit Earth had it happened only a week sooner, frying all electronics across the globe and leaving an impact that we would still be feeling today. NASA estimates the destruction would have cost $2 trillion.

The soothsayers and doom prophets would have been utterly insufferable.

Are You Getting Enough Sleep? - Video

Sleep

The ASAP Science duo (who recently publicly came out as gay) tackle another head-scratching science question: how much sleep do we really need? Is six hours enough? Ten too much? Is there a scientific sweet spot? Considering we sleep a total of 24 years during our entire lifetime and that it factors into our overall health, this is good info to know.

Why The Brain Is In The Head: VIDEO

Why The Brain Is In The Head

It's a sensible question: why is the brain, arguably the most important organ in an animal's body, covered in a thin bone shell on a stalk rather than behind the protection of the central body mass? In short, it's because animals evolved to have all of the major sensory organs - eyes, ears, nose, mouth - clustered in one location, and over time this clump of neural networking evolved into what we now know of as a brain.

You can watch the video give a much better explanation of this process - with construction paper cutouts, no less - AFTER THE JUMP...
