some scientists say there are 10 other say there are 11 dimensions, i dont know which is true i havent really checked that deeply into both, its not really high on my priorities

Im still beginning college so I don't really know too much on this... but here are my questions: - By claiming a 4th physical dimension exists with those arguments... wouldn't that imply a 5th physical dimension and so on? - Also if the 4d object can see 3d, 2d, and 1d objects or whatever, shouldn't we see 2d and 1d objects too? At least I haven't seen 2d or 1d beings.

That was interesting to watch. Didn't learn anything new though, and I'm STILL skeptical on the 4th dimension.

It's just a thought exercise; a 4th physical dimension MAY exist and it may not. Sagan didn't say it exists for sure; he only said that even though we can't imagine a 4th dimension, we can still think about it.

I'm pretty sure ledingrace was just joking.

i dont and never will get the whole time and space thing. Its way too beyond our technology. Maybe in time we will find the truth, but as of now alls we have is men like this who have theories, but it would be cool to know all the crazy stuff with space that we don't know yet!!!!
