Hi, quantum fluctuations enable virtual particles in space. If a rocket travels through space, these particles (real ones of antiparticle-particle pairs) could impact it. Is the effect of an impact dependent of relative speed of such particle and the rocket? For example rocket could be warmed...

i'll try to simplify my thoughts: - space is a link between two points (or objects) - time is a link between two events if a link between two points wouldn't exist, no information/change could propagate from one point into another - so it must exist. for example there's a link between a...

from wikipedia: I thought information about space (i.e. matter) exists in the universe regardless of humans. it's maybe in holographic, 1D or other form, but it is stored outside humans. while information about time is created by humans (by comparing memorised and new information) and...

IMHO that model is misleading, because you need another external space (where grains could exist, where the observer is, and where you actually can bend a paper). As was said earlier (by pervect), spacetimes curvatures are different.

thanks o lot, I think that answers my question

molecules of paper are equivalent to fabric of space, not particles. If we assume that space is discrete, the distance between two points is the number of points of fabric of space (= molecules of paper) between them. If we bend the space/paper, we don't change the distance.

That's what I don't understand. Why will it take shorter time? Light (or equivalent pulse) would allways pass the same number of molecules (the same amount of paper) regardless of how the paper is bent.

You could only measure the distance between paths with counting molecules. The number of molecules is not changing, so the distance would be the same. It only works if bending means creating or removing space.

If you are created by the molecules of paper, you can't tell if it's curved, or strechted. Do we exist beyond spacetime?

If I bend a paper, it doesn't change the things written on it. If gravity is bent space(time), we shouldn't be able to detect it. (e.g. things shouldn't be dragged by it) So why are we talking about bending space, if it's not the space itself that is bending? it's only our mental...

thank you for your reply, but does the time dimension really solve any of these problems? if space dimensions can't store information about where a particle/wave/whatever will be in next iteration (future), then the time dimension can't store that kind of information about *now*. so you...

hi, why do we need to have additional complexity to 3D space? we know that space holds information. but I'm not aware of any information in the universe which is held by "time dimension".. isn't there only changing space and our brain does the "time job" with memorizing and sorting...

so it exists without being stored? I mean.. how can something exist and not be stored?

Hi, if something exists, it must be stored somewhere. a program is stored in a hardware, our thoughts are stored in our brains, our bodies are stored in the universe. the universe exists, so it has to be stored somewhere. so a storage of universe exists - and it has to be stored somewhere...

Hi, what was first: the time or a change? a) time - time enables changes - time exists physically - spacetime exists physically - gravity/acceleration bends local time - high speed bends local time b) change - changes enable us to create concept of time - time...
