Is it possible to stop time completely?

When I was in school, I learned only Newtonian physics. Recently I have discovered that what they taught me was wrong, that gravity is not a force, it doesn't occur simultaneously, blah, blah, blah



Anyway, based on my study of Einstein's relativity, I was wondering if it's possible to slow time...
