  • I have heard the physicist Laurence Krauss claiming that the universe is flat.
  • Okay, but if we take four astronomers and we put one in the north pole, one in the south pole, one in the center of earth's east and one in the center of earth's west and we give each one the same telescope and they all look "straight ahead", all four could see galaxies in pretty much the same amount and distribution --- it's not that only the first two ones (north/south) **or** the last two ones (east/west) would see galaxies so there isn't really any vertical or horizontal "flatness".
  • What is the meaning that the universe is flat?
  • I understood it has to do with the fact that some triangles are straight and some triangles are curved but it didn't help me much in understanding the term "flat universe".

What is the meaning that the universe is flat?
I have heard the physics Laurence Krauss claiming tat the universe is flat.

Okay, but if we take four astronomers and we put one in the north pole, one in the south pole, one in the center of earth's east and one in the center of earth's west and we give each one the same telescope and they all look "straight ahead", all four could see galaxies in pretty much the same amount and distribution --- it's not that only the first two ones (north/south) **or** the last two ones (east/west) would see galaxies so there isn't really any vertical or horizontal "flatness".

What is the meaning that the universe is flat?

I understood it has to do with the fact that some triangles are straight and some triangles are curved but it didn't help me much in understanding the term "flat universe".
