10 of the Most Dangerous Space Walks Ever


In honor of the release of Gravity, Popular Mechanics posted 10 of the Most Dangerous Space Walks Ever Done.  Here are just a three of tidbits…

#10. Hubble Repair: …Had anything gone wrong, the astronauts would have had no refuge or hope of rescue…

#9.  Gonna Need a Bigger Door:  In the early days of the space race, no one knew for sure what was required for space walks beyond a spacesuit. One thing that’s nice to have: a hatch that’s big enough to accommodate a suit that expands when no longer being squeezed by outside air pressure. In 1965, Soviet cosmonaut Alexey Leonov almost paid for that oversight with his life when he couldn’t get back inside his Voskhod spacecraft after his historic first space walk…

#7: Sasha, I Don’t Think…: Decompression is a space station astronaut’s worst nightmare.

With alarms blaring, cosmonauts Michael Foale and Sasha Lazutkin had to use the only tool they had at hand—a kitchen knife…

Time Travel to the FUTURE is Possible


According to particle physicist Brian Cox time travel is possible, but only to the future.  

“Can you build a time machine?” said Professor Cox. “The answer is yes.”

There’s just one, tiny problem, Professor Cox says – if you can build a machine capable of time-travel, you can only travel into the future. You can’t come back.

Professor Cox explains how building a time machine to travel to the future is possible here and here.
