If objects can be infinitely large, doesn't it follow that they can be infinitely small? If that's true, then isn't every space, no matter how small, also infinite in it's proportions when seen from the correct perspective? Lets say I had a spaceship in my living room and had the ability to shrink myself as small as I wanted to. If I continued to shrink and accelerated forward (towards the wall) at the same rate as I was shrinking, wouldn't I simply go on forever without ever reaching the wall? Is there a point where if something is so small it simply pops out of existence?

What kind of effect would the other planets have on our own orbit? It seems to me our orbit around the sun would have to be incredibly wobbly and unstable, yet it is always shown to be perfect. If any object with mass has gravity, wouldn't all those other planets and moons affect us more than they're given credit for? Even if the effect was minute, wouldn't it still be enough to throw all the planets off course in the long run?

If a pipeline has an entrance of 2’ and exit of 1', water flows into the entrance at 100ft/sec. The pressure at the entrance is 200lbs/ft2 what is the velocity and pressure at exit? (Density of water is 62 lb/ft3). I know I need to use Bernoulli's Principle but I do just not understand how to plug in the numbers

I am not familiar with physics or quatum physics so you'll have to forgive me if I don't ask this right.
If space is infinite and the universe is expanding in that "empty space" starting from the supposed "big bang" theory that would have started from a finite amount of matter that was "extremly" dense. Assuming that the whole universe doesn't collapse upon itstelf .... would matter eventually loose cohesion at an atomic level and cease to exist?

is it the very very small distance/displacement of a particle in rotational motion or can it be of any distance in the path of the body cause if it is then we cannot compare it with linear motion since neither is the velocity nor the displacement constant during the motion please help im really confused here

Yes I know it is more stable that way, but why? If particles can spontaneously form from energy as some evidence suggests, how does their spin get started?

I found this movie presenting ideas I'd read were on the way to being proven to be true....Dr. Candace Pert has written Molecules in Emotion and is respected for her research in mind/body field whereas other people in the film have no credentials nor do their ideas hold validity. I was told this movie is completely pseudoscience... Have any of you researched this area....or have read similar ideas in this movie that have been proven by now.
