"moebius strip"
 
   Hello Alexander,

I saw your page about the moebius strip and I would like to comment you an idea that thumbles in my head about it...

Imagine your self step on the Moebius Strip... if you run enough in the forward direction, eventually you will be exactly in your starting point (after a full trip over the strip). If you could see far enough, you probably will see own your back in the horizon so:

1- We know that big masses in space can curve the space-time dimension

2- Demostrate that this curvature could follow a Moebius strip shape

3- Then if get in to that strip - could be using the Sun to curve the space-time around you, as it does with Mercury - you could get back in time just by going forward enough!

a colorary:

4- Looking into the sky you could be looking at the milky way several years ago - after if the ligth got trapped into a Moebius space-time strip to to the space curvature that big-galaxies create. (There are several examples of this phenomenon as twin-starts that really are a single one, whos light has been curved by a big galaxy in the middle)

I donīt know the mathematics behind the Moebius curve, but maybe you could apply the mathematical model to the space-time deformation that the sun produces and then we should have a space-time travel platfform Do you think this is a good challenge? could you, or any Moebius Strip guy you could know perform this?

Best

   Does not your logic apply to a non twisted strip - a cylinder?

   Actually yes... it does...

The Moebius Strip was what triggered this idea and actually it has interesting properties that could mean many different things in the space-time dimension, like that after a while walkin on the strip, you will be step downwards your self - like the matter-antimatter theory. When you deal with cylinder you donīt have this behaviour and also one should think what could mean to move in "time-space" to your left or your rigth... if the thickness of the ribbon get close to 0, then you will have
something that looks-like time, where you only can move forward.

BTW... could you mathematically represent a cylinder in the space-time curvature theory?

best and thanks for your reply

Juan

   The higher matters aside, on a cylinder too if you could see far enough, you'd be able to catch a glimpse of your backside.

   Yes it does! but what about the you-bellow-yourself property?

And also there is something that I dislike from the Cylinder... that you would have an inaccessible face (the inner face) and what could one expect to be there? the Moebius strip lacks this "inner space" and you have full access to the stipīs extension.

Juan

Never discuss your tastes in public. Space-travel-wise I believe
the cylinder will be as useful as the Moebius strip. But we'll have to wait and see.
