Sorry it took me so long to get back to you guys. How is a mixed state a real thing and not just something we don't know? If something is 50% probable this way and 50% probable that way isn't it really just one or the other but we don't know which one? I'm pretty familiar with...

Yeah I tried to understand it but I couldn't completely. So would physical information be something that occurs simply at the quantum level? I got the impression from the Hawking Susskind black hole debate that it had to do with reversibility, so since things happening at our level are part...

They (physicists) say that information can't be lost and I heard Susskind saying that he thought information of objects going into a black hole was stored in the outside of the black hole while the material was sucked in. I thought information was almost like a fossil, where an imprint of an...

I've finally got it down in my mind. Cool link btw.

Well I guess that answers all my questions about gravity. Thanks guys.

If there was a point in space where it wasn't curved by anything what direction would time move you.

I guess. Still weird though.

But if I put a pencil in the air it should stay in the air unless it is moved in which case it would fall along that path of least resistance to the earth. I follow the idea of the path of least resistance but if I'm simply suspended in air I shouldn't fall to the ground until I try to move in a...

Yes that's exactly what I'm saying, the ramp analogy is perfect. I understand that there is space-time but why would time cause me to move in one direction as opposed to another? Time physically moves us along the curvatures of space? When I lift my arm up in the air I'm resisting where time...

And then me lifting me arm up is me resisting that general current headed down towards the earth? I understand that. It still seems like there's a piece missing when things just naturally move along something rather than needing a force to move them. But how does traveling through time...

That makes much more sense to me but at the same time I hear different things. For instance Wikipedia says this: "Modern physics describes gravitation using the general theory of relativity by Einstein, in which it is a consequence of the curvature of spacetime governing the motion of...

I understand that space is curved inwards by the mass of the planet and I understand how curved space could redirect things towards the planet when they are moving. What is strange to me is the idea that curved space time itself could move me towards the earth. Gravity it seems to me is an...
