What's space time based on, lightspeed, or something else? Gravity bends light, so would that effect time?

I _think_ gravity bends space, which alters the flow of time. It also bends light, but I believe that's unrelated. Ya want a better answer, you'll have to wait until Monday when I can prod someone who did more than first year physics at uni.

I think we shouldn't ponder it too much. Super volcanoes, asteroids, blackholes, sun flares and all that. Or maybe we should?

When one of the voyager (think it was voyager) satelites left our solar system it turned back inward facing to photograph it all, the photos were spread out 12foot in width on a wall to capture it all, our little planet just about made a tiny blue pixel (don't know what the resolution was). I don't feel safe anymore

Yep, there was one in Tesco's yesterday. It was on the baked beans shelf, I reached into get a tin and it just vanished, in front of my eyes. I felt my hand being drawn in but snatched it back quickly and all was well, although my fingernails had stretched to twice their previous length, so lucky escape. I complained to the Manager, he said it was not company policy to monitor mini black holes although if a full sized one entered the store they would review the situation, but he offered me some free nail clippers as compensation, so got a result .

Same thing happened to me last Thursday, followed by the Tuesday before. *pause* I hate it when time gets all misshapen.

Edit: On which note, no-one panic too much, it looks like the whole thing may be shut down by the future anyway: FQXi Community: Articles, Forums, Blogs, News - take THAT causality!

What, like trading accounts? How are mini black holes everywhere, this isn't going down the porn route is it?

Did you know, that if you could scale down our galaxy to A4 size it would be thinner than the piece of paper?
