"Curvature of space"... "compression" is a better word

And you know, the greater the pressure of a tire onto a pavement, the greater the traction, the friction.<br /><br />In an area of negative pressure and negative space curvature, gravitational time dilation would be less than 1.<br /><br />If outerspace is like that, what appears to be a parallax showing that it's 4.2 light years away might be actually fooling us. It might be just outside our oort cloud. Yet we haven't past the 1/3 lightyears of it, ever.
