Is it possible to shrink people?

Question

I don't mean a few inches off their height. You can get surgery for that. I mean really small. Like they could fit in the palm of your hand.

Answer 1

No, this would involve either making that person incredibly dense or eliminating most of the molecules that make them up.  Neither of these things is possible.

Answer 2

It could work if you could reduce the amount of space between molecules.  But we just don't have the technology to do that.
