Enlightening Videos on Dimensions

[pineapplebunnybounce]

I don't think the 4th dimension is time. I struggled a lot with the concept when i took intro astronomy in my first year, never really understood what 4th dimension is. My prof said just like a 2 dimension person would not understand 3rd, we won't conceptually understand 4th. I suck at physics but quite sure it isn't time ... because if it was i would've understood it immediately.

I do plan to reread my textbooks some time this summer though.
