N-Dimensional Mirrors

[Jay]

1d- improbable. There would be no light btw the onlooker and mirror. Even if there was some originally, it would quickly be changed into heat energy or something.

2d - possible and very practical. It shows the exact image of the onlooker, without distorting them in any way.

3d - possible but not as practical. It shows the invert of the onlooker in one dimension (right-left). This takes a little getting used to when using a mirror to do an action.

4d - possible but even less practical. It shows the invert if the onlooker in two dimensions (right-left, and I guess up-down).

I guess tetranonians aren't very narcissistic...

tetranonians

funny typo "tetra not onians" so those who don't live in tetraspace

light will probably in any dimension travel in a single direction v, so upon collidng with the mirror surface continue in the same plane (given by the travel vector and the "mirror surface pependicular" p)

suppose p = <0,0,0,1> then the collision would invert the light direction v[sub]4[/sub] ie <v[sub]1[/sub],v[sub]2[/sub],v[sub]3[/sub],v[sub]4[/sub]> --> <v[sub]1[/sub],v[sub]2[/sub],v[sub]3[/sub],-v[sub]4[/sub]> just as in 3d

I doubt that this would mean that if a tetronian shakes his leg, his mirror would nod his head The left right inversion we witness is a phychological onlookers step through the mirror

Surely light can exist in 1D. It will just go back and forth between the person and the mirror.

problem is here that the monodian must carry his own light, if he isn't radiating himself he won't see the mirror through his lightsource.
unless of course every monodian thing is made out of glass but then one couldn't see a thing :wink: .

he could be translucent

Of course there could be a problem with the light, since the point particle/wave that represents the light would have to be only one in the entire universe for the universe to be visible, since then if there were more, when they hit the mirror there would be no image of the person, since the particles have just been bounced back from the one that actually hit the mirror surface, and besides the particle would have to reflect off of the person and then on the mirror and back to his eye, (or at least off of him and to the mirror) and since there is only one direction of motion, that couldn't be possible, and even if the mirror was a half mirror, so that half of the light could get reflected and the rest go through, it wouldn't work since there is only one particle, and it would either go through or be reflected as if either there wasn't any mirror or was a whole one. If there were more than one particles to light, even then it wouldn't work, because if only one of them got reflected, then all the others would have to go back and hit reflect off the surface of the person and make a domino effect back and forth, until all of them go through the half mirror (a whole mirror would have gotten them stuck like blackbody radiation until all the energy got transfered into heat/sound etc.) I suppose if there was some kind of data transfer between the light particles in the 1D world could maybe there be some kind of a reflection, otherwise I suppose the 1D world would be a very dark and maybe cold place to be in.
