Most likely, Eventually, yes.
It depends on what you mean by above and below. Above the north pole is Polaris and above the south pole is Octantis. This changes due to the Earth's precession. To read more about this, look at the wiki for pole stars. |
u mean that it is like a almirah and we r at one shelf while there r other shelves below and above us???
but that should create gravitatonal force on all planets and sun as well in up or down plane.but they show no such force.
also none of them moves in vertical plane.
planets revolve around sun and sun itself around centre of milky way which itself is a spiral shaped.
m-theory is just a integration of 5 string theories into one
string theory showed how all the particles, and all of the forms of energy in the universe, could be constructed by hypothetical one-dimensional "strings," infinitely small building-blocks that have only the dimension of length, but not height or width
