Eugene Posted June 4, 2002 Report Share Posted June 4, 2002 It is suggested that just as itis not possible to describe the absolute static condition or perfect circle neither can there be accepted the possibility for the absolute straight line. A question arises regarding the theory for space curvature. Do we have any evidence or definitive figure (however minimal) for degree of curvature of the line? Does the curvature of space by its immensity have a 'gravitational' effect upon a so-called straight projection? Eugene Link to comment Share on other sites More sharing options...
Astronomer1302 Posted June 8, 2002 Report Share Posted June 8, 2002 No in space I do not believe a straight line is possible. The space curvature won't alow it. Link to comment Share on other sites More sharing options...
Astronomer107 Posted June 8, 2002 Report Share Posted June 8, 2002 I have a paradox that states mathematically, in the univere, a straight line cannot exist; however, it probably was thought of before me. That's the problem these days... hehe... no room for anymore ideas! A straight line may exist if it leaves the fabric of spacetime, but if it stays within the universe, and the universe curves, then the line will no longer equal 180 degrees, and thus is not a straight line. So, it depends on how you think about it. But as long as the line exists within the universe, it will not be a straight line. Link to comment Share on other sites More sharing options...
Eugene Posted June 9, 2002 Author Report Share Posted June 9, 2002 Is there a formula giving or estimating the effect of space curvature upon a straight line?Eugene Link to comment Share on other sites More sharing options...
Noah Posted June 9, 2002 Report Share Posted June 9, 2002 If, because of the curvature of space, there is no such thing as a straight line, does this also mean that there is no such thing as parallel lines? Noah Link to comment Share on other sites More sharing options...
Eugene Posted June 10, 2002 Author Report Share Posted June 10, 2002 I would suspect that to be the case. Then there is also the question of parallax lines, as in astroscience, etc. Link to comment Share on other sites More sharing options...
Mallory Knox Posted June 18, 2002 Report Share Posted June 18, 2002 I think the concept of a straight line is really more of a theoretical thing. You can't actually make (draw) a line, let alone a straight line. Link to comment Share on other sites More sharing options...
Eugene Posted June 18, 2002 Author Report Share Posted June 18, 2002 Mallory,I agree...but why do you think that is? Does space have curvature which effects a sort of gravitational force upon straightness; and if so, would that not suggest an aether?Eugene "We have nothing not given and nothing given not asked for."

Mallory Knox Posted June 18, 2002 Report Share Posted June 18, 2002 I'm just saying you can't create a 1-dimensional object inside a 3-dimensional world, there are no lines here. A line is what you tell it to be because you make it up it. Curvature of space can't affect something that doesn't exist. Link to comment Share on other sites More sharing options...
Eugene Posted June 19, 2002 Author Report Share Posted June 19, 2002 Mallory, If the curvature of space doesn't affect what we call a line, then what does? What physical effect? Do you have a formula for it? Eugene Link to comment Share on other sites More sharing options...
Mallory Knox Posted June 19, 2002 Report Share Posted June 19, 2002 How can something physical affect something that's imaginary? Link to comment Share on other sites More sharing options...
Eugene Posted June 20, 2002 Author Report Share Posted June 20, 2002 Mallory, At Last! I have found my mentor! Now that we have the line out of the way we can concentrate on curvature. Why is it that whatever distance on arc of the quadrant that figure multiplied by 8 gives the radian? Thanks in advance.... Eugene Link to comment Share on other sites More sharing options...
Eugene Posted June 23, 2002 Author Report Share Posted June 23, 2002 Mallory,It turns out that your perception is wrong. It is the length of the line that is illusionary, not its dimension. Though I would like to know how you came up with such a notion. Eugene Link to comment Share on other sites More sharing options...
