because, when you bounce a basket ball, in the outside, like on a driveway, you hear the echo maybe half a second later. but when you flick a light switch, the light goes on immediately. but then, the sound has to travel to the atmoshere and back, so what is faster?

The Earth is a sphere. Imagine a toy plane on top a beach ball. If you push it fast enough it will come away from the curve of the beach ball. Now imagine the ball suspended in the air with gravity in the centre of it and the toy plane had a constant controlled force behind it, push the plane slowly and it will just travel round the ball always in contact with it but push it fast enough and it will travel around the ball at a distance away from its surface, is this the same as flying? Is flying really just controlled falling round the curve of the Earth?

Before 10^-43 seconds after the Big Bang occured, all four fundamental forces of physics were unified, therefore it is impossible to deduce what occured at that time, when time and space didn't even exist. Essentially I'm asking what happened before there were physical laws, the creation of matter, and the beginning of the expansion of time and space; the beginning of time?

then might this system be very much like dutch dolls or an onion. All of each matrix making up the one level. In other words a system of Universes, in which the building blocks are infinitly angular i.e smaller universes. Our level is but one in an infinity of levels. so that the 20billion light years is but a mere nothing to the next level?

Illustrations of multiple dimensions remain unclear to me, so how can an average person like myself really visualize this, or see signs of it in the natural world?

Michio Kaku kind of touched on this with his "fish in the pond" analogy, but could one of you guys, or gals, please expand a bit further?

Thanks. :)
