Okay, I understand that the universe is expanding. I also understand that in 1998 Cosmologist discovered that the Universe is accelerating rather than decelerating. My question is: "By expanding, do they mean that the mass in the universe is becoming more spread out, or is space time actually stretching out?" The idea that space-time itself is stretching out doesn't seem right to me. I'm just wondering.
Thank You
