A friend of mine, likes to sit outside at night and look at the stars. However, there is one star that is much brighter and bigger than a normal star. Even when there are no stars out at night, that one is still out and brighter than ever. It also seems to move. One minute it is in one place and the next it is in a totally different place. He claims that it isn't a star, that it is a satellite put there to help the law watch people. I say he is crazy because if that was the case, more criminals would be going to jail. Has any one notice this star or know what this could be?

to make it clear I'm talking about a 4th spatial dimension, not time as the fourth dimension.

i was reading a book by Stephen hawking and came to a weird conclusion. if we have a cube and pass it through a 2 dimensional plane an observer in that 2 dimensional plane would just see a square. so by that logic a 4 dimensional object, lets say a hypercube, would just look like a cube to us. so could all of the objects around us just be 4 dimensional objects in our 3 dimensional universe.
