according to M-theory, there should be 7 ekstra spatial dimensions curled up at the plank lenght, but why do they need to be curled up? if light and matter is bound to the 3rd dimension like waves of the ocean is bound to the 2D surface of the water that wouldn't that be sufficient for us not to...
I know exactly how this is explained, what I don't know is why these dimensions have to be curled up when a much simpler explanation could be: The reason why we don't experience these additional dimension is that none of our particles can move in these directions, and therefore are stuck on our...
I know that the compactified additional dimensions is the standart explanation, but the way I have thought of this is: The reason we can't see these dimensions, is that light fotons are bound to the 3rd D, and can't escape. Just like waves at the ocean can't escape its 2D surface. and neither...
i know that the compactified additional dimensions is the standart explanation, but the way i have thought of this is the reason we can't see these dimensions, is that light fotons are bound to the 3rd D, and cannot interact with the higher dimensions, just like the mass cannot escape 3D...
but won't the intensity be increased near the center of the sphere?
like if you are projection light though a glass sphere on a paper, where the geometrical form will be a filled circle, but with a darker fill in the center? as 1/r^{2}
why? doesn't it has a higher dimensional angle, that...
according to string theory, gravity got the ability to escape the D-brane of witch all matter is bound. The reason is that the boson carrying the gravity is a loop-string, with no open ends linking to the brane.. this theory should explain why the gravity is so much weaker than the other forces...
which means that the change of the law being violated is regarded as zero, but not that it is zero?
and if the amount of particles in the containers is just small enough there actually is a good change that a sepperation might be the case

when i read this i was wondering, what if the deamon accuires no information at all and just shoots blind by guessing wherever a approaching particle is A or B..
in most cases the demon would end up with a no separation, but if its lucky...
thank you for your reply, but don't you mean the opposite? that the vertical position will change as a result of a perpendicular swing, and that the horizontal position will remain unchanged?
I'm assuming that the horizontal axis is parallel to the line of the pendulum and that the vertical...
As a school project I was assigned to measure the swing of a pendulum. At the time I was doing the experiment I found it almost impossible to prevent the pendulum from moving in an ellipse, at first i describe the elliptical movement as a source of error, but then it occurred to me that it might...
