What If The Sun Disappeared?

Everyone is curious about what would happen to Earth if the sun disappeared. In short: We’d be hosed.

Popular science educator Michael from Vsauce returns to the web to discuss gravity and the Sun. As a thought experiment, he asks the interesting hypothetical, “What if the sun disappeared?“

It’s not going to happen, but interestingly enough, if it did, we wouldn’t be aware that anything was wrong for a good eight minutes, as it takes that long for light to travel the millions of miles from the Sun to the Earth.

The Facekini

This is a little creepy!

Beach-goers usually use sunblock and umbrellas to make sure they don’t get burned, but in China they use something called a “facekini“. The fact that it makes you look like a Mexican wrestler doesn’t seem to bother anybody.

The facekini is being called “China’s latest beach craze”, but according to a Qingdao sales officer, the bizarre mask has been around for at least five years. But photos of Qingdaonese swimmers wearing the bizarre accessory have only recently gone viral on Chinese social sites, and were eventually picked up by Western photo agencies and websites sparking readers’ curiosity. The bizarre clothing item is made of elastic fabric, covers a person’s entire head and neck down to the collarbone and has holes cut out for the neck, nose and mouth. They look pretty creepy, if you ask me, but that’s apparently a very small price to pay in order to protect yourself from getting a tan while going for a swim.

NASA | STEREO Reveals the Entire Sun

On Feb. 6th, NASA’s twin STEREO probes moved into position on opposite sides of the sun, and they are now beaming back uninterrupted images of the entire star—front and back.

“For the first time ever, we can watch solar activity in its full 3-dimensional glory,” says Angelos Vourlidas, a member of the STEREO science team at the Naval Research Lab in Washington, DC.

Video Description:

Launched in October 2006, STEREO traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. STEREO, when paired with SDO, can now give us the first complete view of the sun’s entire surface and atmosphere.

Solar “Death Ray”: Power of 5000 Suns!

I have my doubts about this. Would you hold your hand that close to something so powerful?

Video Description:

The R5800 is my latest and greatest solar creation. Made from an ordinary fiberglass satellite dish, it is covered in about 5800 3/8″ (~1cm) mirror tiles. When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 suns! This amount of power is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5’9″ and is 42″ across.
