Re: This is how fast our universe is expanding

^ just like that movie event horizon theorized, folding space and time. great movie! i didn't even really think people imagined that idea plausible. i thought it was just something made up in the movie that sounded cool...

I think the theory is pretty old, objects in space with extremely large masses exert massive gravitational pressures and stretch space. So massive, that in fact light from stars curves around the object as it passes it. If light curves, it takes longer to pass and so now there's a stretching of time and space. So scientists theorize that if they can reverse that pressure, they'd compress space time so an object could essentially travel faster than light for the same distance.

Wikipedia's version is a bit more complicated, but really fascinating

whoa, if accurate (and i read it right), it means that the universe will appear to stop expanding past 16 billion years?

No, it means that one day the Universe will appear void to us , 16 billion light years of freakin emptiness. That's pretty mind-boggling, huh?

so hard to wrap my mind around 16 billion light years!
