: I'm sorry, but the only lesson I'm learning is that physicists should always
: have a basic grounding in epistemology. For example, early in the video it
: says "We now know the universe is flat". My intuition says this
: is just bad epistemology, nothing more. For one thing, that entire section
: on the 'shape' of the universe assumes the universe is finite, which is
: certainly possible and perhaps likely, but there's truly no way for us to
: know at this stage, is there? For another, it assumes that whatever we
: think currently is just 'right' and we now 'know' the truth (a common
: mistake among physicists that just again proves they should study more
: epistemology, or maybe just more philosophy in general). I could go on,
: but really I just don't care enough to do so - all in all, the video made
: me cringe mentally.
:The word "flat" has a specific meaning in cosmology.
