"Flat Universe"question.
Hello, everyone!
I'll start by saying that astronomy or physics are not my majors here; I'm a freshman Med School student, however I've recently started amateur astronomy as a hobby. Naturally I had to increase my knowledge on this subject so I started visiting different astronomy sites and youtube videos and I came across this video. At around the 40 minute mark, Mr. Krauss states that the Universe is flat when looking at the CBR. I didn't read too much into it because I still have my own studies to attend, however, if someone here could simplify it, like, for example: The 2D Universe on the surface of a balloon is expanding in 3 dimensions or something like that.
Sorry if this request sounds dumb or wastes anyone's time, but I tend to have these moments where I HAVE to realize how something fits.
Thanks! :)
