Well hypothetically if the Earth was destroyed by grey-goo or something, the disc would still be there. But the other answer is that it's much easier to find.

Well hypothetically if the Earth was destroyed by grey-goo or something, the disc would still be there.
But the other answer is that it's much easier to find. Where would you put a ceramic copy of wikipedia on Earth to maximize it's probability of being found? Anywhere you put it could get destroyed, buried, or stolen. Who knows what will happen to it over the Eons.
This disc will be on the surface of the moon forever. Anyone surveying the surface of the moon for unnatural objects will find it. Although that might take some advanced technology, it would be easier than surveying the Earth.
And while they might find many artifacts on Earth, locating that single copy of wikipedia out of all the other junk we've left behind is a bit improbable. We haven't covered the moon with much junk.
- icebraining 11y agoThis disc will be on the surface of the moon forever. Or until a meteorite hits it.
- Florin_Andrei 11y agoIt's true. The surface of the Moon is a lot less peaceful than it seems. If you process the image, you can tell the affected area from a single meteorite strike is much bigger than the crater itself: http://www.astrobin.com/full/220884/0/ http://www.astrobin.com/full/220884/0/
- gcr 11y agoHas anyone compared the surface of the moon over time? We can count how many meteorites have hit the surface since we've been taking pictures of it, and we can also probably assess the actual damage they've caused.

- tamana 11y agoHow do "Earth-based observations of the dark portion of the moon" work? Is that the dark part of the light side, where the sun won't overexpose the video?
- Florin_Andrei 11y agoIt's as easy as night versus day. Flashes from bolide strikes are actually easier to see on that part of the Moon where it's night. Where the Sun is above horizon on the Moon, the ambient light is drowning out any light-producing events.
