the biggest fail to ever come out of playstation. what playstation has worked on for 4 years has turned out as a big fail. its a 3-d online world where you can use an avatar to represent yourself. where can talk to people using thought bubbles and also do actions with it pressing r1. but mostly everyone were mostly interested in hitting other peoples avatars. every girl avatar that you see in ps home is probably a guy trying to get some attention. (note for all you guys who try to flirt with girls in home: DON'T EVEN FUCKING BOTHER. THEY ARE PROBABLY GUYS AND YOU GUYS ARE EVEN STUPID ENOUGH TO BELIEVE THAT. WHAT GIRL WOULD EVEN GO ON PLAYSTATION HOME. IF YOU WANT A GIRLFRIEND JUST GO TO THE FUCKING MALL AND ACTUALLY GET OUT OF YOUR ROOM PLAYING YOUR PLAYSTATION!!!)

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
