    Earth Slope Space Tube
Click For Summary

Discussion Overview

The discussion explores the hypothetical scenario of anchoring a tube on Earth that slopes into space, examining potential outcomes, theories, and related concepts such as the idea of a space elevator. The scope includes conceptual reasoning and theoretical implications.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant questions the implications of anchoring a tube into space and whether any phenomena would occur, expressing a lack of advanced physics knowledge.
  • Another participant asserts that the only result would be a long tube extending into the atmosphere, explaining that gravity prevents air from flowing through it, leading to a net flow of zero.
  • A different participant introduces the concept of a space elevator, suggesting that if the tube were of the correct length, it could function as such, albeit without the elevator mechanism.
  • Participants express enthusiasm for the idea of a space elevator, referencing materials like nanotubes as potential components for its construction.

Areas of Agreement / Disagreement

Participants generally agree on the basic outcome of the scenario, but there are differing views on the implications and potential applications, particularly regarding the concept of a space elevator.

Contextual Notes

The discussion does not delve into the technical specifications or feasibility of constructing such a tube or elevator, nor does it address the assumptions regarding material strength or gravitational effects in detail.

Who May Find This Useful

Individuals interested in theoretical physics, engineering concepts related to space exploration, and the feasibility of advanced structures like space elevators may find this discussion engaging.

All right, I know I'll make an azz of myself with all the big brains around but I have to know. (My physics knowledge is at a high school level so please forgive my ignorance)

I we were to anchor a tube on Earth and slope it all the way into space, would anything happen? Has there been experiments? Theories?

Just my stoner brain I guess :)

Thanks guys!

The only thing that would happen is that you'd have a very long tube sticking out of the atmosphere. There would be no flow of air through the tube for the same reson that the atmosphere doesn't blow away into space: gravity. The pressure difference between the top and the bottom is exactly offset by the force of of gravity so the net flow is zero.
 


Thanks a lot neg. Makes a lot of sense (even to me) :-p

Great link, ideasr. Go nanotubes...want to see that elevator built in my lifetime.
