    Can time dialation really just be the slowdown of physical processes?

    A quantum of time doesn't fit into any theory I'm aware of; what are you talking about? Time is either a measurement, or a dimension; you might as well ask for the quanta of length. These are not things which ask for or require quanta, even if they have a limit to their divisibility.

    What I've read since just confirms your supposition: after a lot of hard work this is another confirmation of GR to within .2% . From eclipses to to the smoothest spheres we've ever made, GR just keeps on keeping on.

    Anyone here play Portal? Portal + Relativity question

    OK, that does make a great deal of sense, and it answers the other question I was going to ask. This forum is fantastic for people trying to write fiction that doesn't utterly trample physics. Thanks JesseM. I'm curious, what would the radiation field around this kind of portal be like in...

    Anyone here play Portal? Portal + Relativity question

    If you had these portals, but they had a delay system so that they operated to only allow passage at or below 'c', it would not fall prey to the issue of time travel, right? In short, if you teleported (scifi) halfway around the Earth, but you stayed just below 'c', you would just have a REALLY...
