Moon Stick
It moves away from us at about 2 inches a year | |
In an equatorial zone of the moon on
the side that faces us, have a pole
pointed at the Earth that is marked
off in 2 inch increments. Have the
incriments translated into dates of
when the moon was approx. that
much closer at that time in the earths
history. Each year slide the dates
up
the pole by one unit.

That'd be one costly ruler. |
|
| |
What good does it do anyone if it's on the moon? |
|
| |
Just 'cause I suggest it doesn't
mean we have to do it today even
though it is possible. Perhaps, at
sometime in the future as an
exhibit in a museum this would be
a powerful example. For now you
can do a virtual version of this on
your computer. Make a 3d version
or photoshop something together. |
|
| |
Oh, so that's why the moon looks bigger in old photographs! |
|
| |
No, that was a different moon
entirely. The moon you see today
is refered to as the New Moon. :) |

Maybe you could have one of those signs with a whole lot of place names angled to indicate direction with the distances next to the name. You know those signs at tourist hotspots. And every 20 000 years you add on 1 kilometer. Pity all the arrows will be pointing in the same directon, and the distances would have to be updated realtime and what is the point really. |
|
| |
Gets a fish... the ruler could not be constructed as it would need lots of the material unobtainium which is presently unobtainable. |
|
| |
This doesn't make much sense. 2 inches is insignificant when you consider that the moon has about 30,000 miles of play in its eccentric orbit. |
|
| |
[venomx] what part of this is
unobtainable? Going to the moon
or putting a 16 foot high pole on
it? Hasn't past history shown that
we can do this? Did everyone
think that I was trying to connect
the two celestial bodies together
with a pole? The approx. 2in
measurements would be for show
as a central point in a museum,
the same thing could be done here
to show the distance the moon
moves away from us. |

// I couldent help but to notice that it took approx 3 years for the event to occur, since the last time. // |

There's no particular significance to this. Lunar eclipses occur just about every six months or so. It's been three years since one happened when it was night on your part of the planet. There'll be another you can see in November, provided it's not overcast like it was on my part of the planet last week. |

sartep, did you see my comment? Are you aware of the terms "apogee" and "perigee"? Could you perhaps explain the point of this idea a bit more clearly? |
|
| |
Sorry waugsqueke, yes I do
understand apogee and perigee.
But the moon is moving away from
us. Even though it has an
eccentric orbit, the radius of that
orbit is on average 2 inches more
each year. Since the same side of
the moon faces the earth, I felt a
stationary pole could be placed on
the surface giving an indication of
past orbits. |
|
| |
True, this wouldn't be the most
accurate measurement, at best it
would be a simplified example to
prove a point of the moons
increasing distance from the earth. |
|
| |
Ultimately, it would be designed to
look the way poles here show past
ground levels with dates next to
them. |
|
| |
No and no, however the lightwave
version of doppler is redshift/
blueshift. |
|
| |
sartep, it just seems to me like a very arbitrary and inaccurate thing to measure, particularly located in a place where not a soul will see it, and for no real reason that I can ascertain. |
|
| |
nacho, the red colour is due to the refraction of the sun's light passing through the earth's atmosphere, around the edge of the shadow, before striking the moon. It's the same process that causes red sunsets. |
|
| |
Sorry, you've lost me. Are you drinking, by any chance? |
|
| |
Ah, right. I just hope you're not driving anywhere. |
|
| |
Waugs, just because it could be
built today doesn't mean that
would be the best idea. However,
it can be designed today, like
many things. However in the
future there is a very good chance
many eyeballs will glance at a
thing like this. Maybe in perhaps
the first lunar museum or
something. |
|
| |
Ah, therein is the beauty of it - when an irresistable force meets an immovable object - they become dust free. So, when we get slammed into by the moon yo-yo - the ruler will once again be legible. By who, I don't know, as there will be few survivors. Best if the ruler is marked in metric *and* capitalist pig. |
|
| |
That's funny as hell, thumbwax.
Yeah, I'm not really the biggest fan
of building on the side of the
moon that faces us. But you
know, that those landing spots will
be places of interest in the future. |
|

You want the moon on a stick! |
