Fact, snippets of useless information and all of that kind of thing makes up most of what’s in my brain – so I thought I would infect the general interweb with al of this and see what fact I can trawl for you!

Enjoy!

Did you know…

To get to the nearest star at 1/10th of the speed of light using current rocket technology would take 42 years and need a hells lot a fuel!

When do we start?

  1. Simon, my wife asked a pretty good question tonight while watching Nova. It was, “Who decided north was up on a map?” It stumped me and there is no definitive answer from what I found. A Greek by the name of Ptolemy (2nd century AD) seemed to know the world was round and drew lat/lon lines on his maps defining its curvature. There is much more to the story, but north wasn’t always placed at the top of a map until the mid- 1500s.

    Maybe a quizz question to see what folks find?

      1. Part of the data I saw said exactly that. In engineering we draw/build in XYZ coordinates with Z “up”. In ship and aircraft building we use “XYZ” to represent station line, butt line and waterline – with Z/waterline as up.

        In spacecraft we use roll/pitch/yaw for axis system’s. There is no up.

  2. Yikes! That’s 42 light-years, right? I’m not even going to try to calculate the mileage. I’m guessing the number has a lot of zero’s in it.

    I would say it’s obvious that humans aren’t going to make that trip any time soon. They would need too many consumables for just a one-way ride – no way they would make it back. If we sent a probe there, what would be the delay time for communications with it? Days? Could we boost it with a “nuke” and get it there faster? Inquisitive mind here…

    1. It’s 4.2 but we’re only going at one tenth of light speed. The mileage is somewhat HUGE!
      Communication time would be years back and forth if we sent a probe there – radio travels at the speed of light or thereabouts.
      There is a treaty in place that no one will set off a nuke in outer space. I like the principle but I wish they would create a similar treaty for Earth.
      Basically we need to create technology that give far more bang that we currently do! 🙂
