I don't know, that's a question I've asked myself for years and still think it'll never be obtainable. Time has a big ?mark because what is time? Given, it is a dimension... but it's way more complicated than that. Like I said in another thread, time is only a record of the past that doesn't exist anymore. Present is a precise instant that constantly renews itself. But I don't think we could ever "defeat" what we call time...at least this is what I think
