Hi all, I had no idea were to post this, so a mod feel free to move it.
But a friend sent me this link, not that I no much about any of this science stuff, but this kind of makes me worried when I read the article right through.

Thoughts??

"Kids! The world is gonna end so I packed you a bag-lunch and a trip to Andromeda! Send postcards!" *makes kissy noises as world is being ripped apart*

Nice one!

Just hope they share the energy! The possiblities of this energy is endless, we could even power a matter converter!

As somebody in the comments (correctly) did the math:

200 petaWatts * 1.5 x 10^-14 seconds = 3000 Joules.

While that is an enormous amount of power it's not a heck of a lot of energy.

Depending on your electricity rate it's a bit over 1/100th of a penny.
