In progress....
What's Involved: Okay. There aren't many options here. Actually, there are probably only two basic ways: removal of matter, or compression of it.
The first is out, unless you're for the "it's magic" explanation. Matter can't just disappear and reappear. Where would it have been stored in the meantime?
Not only that; there's no way a body could work as well. Our brainsareyhtkhvkvkvh b,,hfgcccct6i6fd57

Okay. So how about compression? That sounds good. Everything's still there, just squished tighter together. But it fails, too. We don't compress well. xhfcjgbkbljlbj

There is a related possibility. However, it's quite a stretch. It involves compression of actual atoms. But that means altering Planck's length, which is considered a constant (unchangeable.)
Final Verdict: No way!
