By the why, while the original link doesn't work, if you want to see what it was about it can be still be found here

On an unrelated note: if you made a one-way freeway along the earth's equator, and had traffic driving across it, would it cause our days to grow shorter/longer? It seems to me it would, but only so long as the traffic is moving. To make things really silly (because the original idea was perfectly serious and not at all silly), even though the jump doesn't move the earth, any movement of the earth on the way up being undone on the way done, there might be a tidal effect while the people are in the air, so it could slow down the earth's rotation...

It was on the BABB. It can now be found hereBe warned, this thread has a lot of toilet humour. But is darn funny. It took me a while to stop laughing enough to be able to post - but I'm tempted to add the following quote from JayUtah to my sig file:

Funny stuff.
Regarding the UAOI: How would you account for the propulsion assembly being so far off from the center of mass on most units?

Well the distance from the centre of mass isn't a huge problem in rocketry, the bigger problem is that the vector of the thrust is unlike to be through the CoM which could lead to a serious tumble if the Astronaut holds the equipment at an incorrect angle. Luckly however it was designed in such a way as to allow for easy adjustment.

That's funny. It reminded me of an interview with a Washington DC cop, who was giving advice on how to best avoid getting shot by the DC sniper. He said "Walk sideways". True story. I wish I could find a link to the article.

At least it's rather easy to vector the thrust.

My Physics teacher told me it is not possible to alter Earth's Orbit in this way. When the people jump, the people and Earth distance from each other: the people "go up", and the earth "goes down", if I could put it in those words. Gravity attracts one another, so then the people "go down" and earth "goes up". (This sounds like the earth flops away for a great part, but that's not very true: it'd be nearly immeasurably small.) Which would bring yourself in the same situation before the jumpings.
This is about what my Physics teacher told me quite a long time ago; he might not have literally said what I just typed.

Exactly right, you'd have to cast something off of the earth to get it to move. And it'd have to be a fairly large chunk of stuff too. Or have it leaving very very fast, I suppose.

OK this is slightly O/T but I have a friend who works for a Communications company , they doing a lot of work for oil companies here in the NE of Scotland setting up links to platforms -
These days is most Satelite based,using Geo sats - there's an obvious delay - so one of the managers in one of the Oil companies , frustrated with the delays , phones my friend and asks f there's anything they can do about these delays's
"Yup" he said , just give up a blank PO to amend the earth's orbital velocity - and we'll get right on to it" ;D - it took a while for it to sink in at the other end of the phone! - there then followed a brief lecture on Clarke Orbits , the Speed of light , and other relevant topics!
