Thanks. I agree that pressurising aluminium tubes probably isn’t the best method. I’m working on other methods that include pre-stressing styrene foam, cable-staying and creating an inverted conical shape with the wing spars and tying them together with multiple lines like a spider‘s web...

Thanks.

I’m designing and hope to build a human powered helicopter (HPH) and am wondering if pressurising a thin walled aluminium tube by filling it with compressed air would strengthen it’s structural properties. Hope this is the right place to post this.

If time dilation is a consequence of moving and time dilation is essentially “moving slower” then why doesn’t time dilation affect the motion that causes it? How does the time difference of time dilation occur without acceleration?

I guess it is essentially what I’m asking. Specifically relative acceleration. Can you give a non-mathematical, simple as possible explanation why it doesn’t?

Does the relative motion of a thing slow down the relative motion of a thing? Hope that makes sense or you can work out what I mean.

Thanks for all the posts. Merry 2010/2011 and beyond.

So "I" is defined by the current number of monkeys? Doesn’t this "anything is possible" approaoch remove any particle meaning and use of the term infinite? In other words hasn’t the very meaning of infinite been changed and not just the numbers system? ETA - Isn’t infinity merely a...

In a newly created number system would it be possible to say that the current number of monkeys in the world is I (infinite) and when a monkey gives bisth it is I + 1?

Can you have infinity plus or minus one? Assuming infinity is possible of course.

I don’t see how you can have any form of existence without having time. Given there must be things that exist to have distance between them I would conclude that you automatically must have time if you have distance. Even if distance doesn't "need" time. Does that make sense?

Don’t see how a thing taking different times to cover the same distance in different circumstance means in any way that “it IS possible to have distance without time”.

Thanks - That's probably the best answer for my purpose.

Sorry but I can’t relate any of that to my question.

Thanks - General Relativity aside, would it be possible?
