Julie I believe the word you want is "posterior" !

What would moving to a larger orbit do to our expensive watches and grandfather clocks ??

I don't believe so William, I meant 'future generations':.

@Julie,
maybe if we put a sails on those asteroids 1 day...& sail with them across Solar system... ;)


Right, where the non-existing universal vacuum winds will propel us further to our destination ;D

Larger orbit means that we would have longer years not longer or shorter days.

Yes, assuming that the spin rate has not changed. However what would happen to the month and day indications on my watch if there were more than 365 days in one orbit around the sun. Also the seasons would get out of whack.

Spin rate of planets has nothing to do with the distance to the Sun.
Yes. You have to adjust month and day indications on clocks if earth is moved to a larger orbit.
But a day would still be 24 hours.
And the seasons will be longer.
What happens if they do I have no idea.

"Months" are an artificial time interval, unlike "days" and "years" which are directly related to the earth's rotation around its own axis and the rotation around the sun's axis respectively.
If you increased the "radius" of the earth's rotation around the sun by say 10%, but kept its own axial rotation rate the same a day would still be 24hours, but the number of days in a year would increase. Thus the calendar would have to have more days in it, which would imply that either a new month would have to be inserted, or the number of days in each month would have to be increased.
As for seasons, these are the result of the axial tilt and the rotation around the sun. Assuming that the tilt stayed more or less the same the seasons would still exist, but they would all be colder as there would be less energy input from the sun.

Not in religious communites and business accounting:)

Yes. It's much colder further out from the sun.

At the point that earth might be moved, the sun will be expanding and we will need to be further out. Can't really imagine us being able to do that though.

by d time Earth will have to be moved, we'd have to be @ least all over 1/2 of Galaxy...we're talking about "millions of years" in future!

This is all assuming there would be enough left of the Earth to salvage, of course. It's hard to imagine cosmic engineering when we can't even pick up our own trash.

No, I'm just wondering out loud what kind of shape the planet will be in by then. We won't need any extinction event to take us out at the rate we're going.

well, people are more obsessed about THINGS & MONEY, then about progress...yes, it costs some money...but it's the fact of the Goals!

we haven't put a clear Goal to go to Space...yet!

A new quantum teleportation distance record has been set

Building an entire "quantum Internet", would be faster, more efficient, and more secure than the networks we rely on today.
But if you want a backup of the information?

What particle was used? How did they know which one was the partner? How did they sync their clocks to measure the times.

Please describe what is meant by a "quantum internet" and how it would work.

While you are at it, enlighten us on how a quantum computer would work and why it is better than what we have today in sophisticated chip and computer architecture.

That was many question William.

It was photons.
Please describe what is meant by a "quantum internet" and how it would work.

Quantum computers works with qubits instead of bits.
That make Quantum Computers "QC" ideal to factorize integers.
While you are at it, enlighten us on how a quantum computer would work and why it is better than what we have today in sophisticated chip and computer architecture.

I let Seth LLoyd answer to that:)
