2wlp1d | If neutrons are electrically neutral why isn't the universe filled with free neutrons? | My assumption is that free electrons have a tendency to bind with protons as atoms so that is why we don't see free protons as much. | askscience | http://www.reddit.com/r/askscience/comments/2wlp1d/if_neutrons_are_electrically_neutral_why_isnt_the/ | {

4mw7h3 | After the dissolution of the Soviet Union, Russia was voluntarily deemed the sole successor state to the USSR.

3oby2f | How did the Soviets falsify photographs | I would often see photographs in history textbooks such as this _URL_0_ and it baffled me that the Soviets could do such a brilliant job in doctoring photos even before the existence of Photoshop or computers for that matter. Heck, their 'photoshop' skills are even better than some people's attempt at photoshop today.
