I think this is a very interesting project and well worth reading up on it. Also if the designer Danny Hills has come up with something which can run for ten millennia with minimal maintenance and interruption then it might mean a rethink on service revenue for Omega ;0)

I appreciate their optimism that we will exist in ten thousand years

 

I think they are just optimistic the clock will exist …..

 

If you want to see someone looking really long term how about 8.4 million years..... and it is just as beautiful as anything the Pharaohs came up with... not a bad legacy if that is all we end up leaving as a calling card....
Time capsule: LAGEOS-1 (which is predicted to re-enter the atmosphere in 8.4 million years[6]) also contains a plaque designed by Carl Sagan to indicate to future humanity when LAGEOS-1 was launched. The plaque includes the numbers 1 to 10 in binary. In the upper right is a diagram of the Earth orbiting the Sun, with a binary number 1 indicating one revolution, equaling one year. It then shows 268435456 (in binary; 228) years in the past, indicated by a left arrow and the arrangement of the Earth's continents at that time. The present arrangement of the Earth's continents is indicated with a 0 and both forward and backward arrows. Then the estimated arrangement of the continents in 8.4 million years with a right facing arrow and 8388608 in binary (223). LAGEOS itself is shown at launch on the 0 year, and falling to the Earth in the 8.4 million year diagram.

 

Is this the Jeff Bezos project?

 

In terms of the clock I think not originally but he became involved for the funding.

 

Ah ok. understood, Thank you

 

That is truly a long, long time. I'm a fan of Carl Sagan but hadn't heard of this project.

Something else from Sagan's Cosmos series that makes long timescales more understandable is the concept of the Cosmic Calendar. Take the 13.8 billion years of the universe's existence and scale it down to 1 year. So each second in that year represents 438 years. All of recorded history takes place in the last minute of the last hour of December 31 for example.
