so, many shows on tv today that keep suggesting our universe is expanding. is it really?(adsbygoogle = window.adsbygoogle || []).push({});

1. if you can say "it is expanding" doesnt that imply you 1st have to know how big it is now, then make a observation (measurement)? so if the universe is already infinite in size how can anyone say its expanding (we cant measure infinity).....?

2. if the universe was a cube of space with the 2-dimensional sides increasing in size at the known max speed limit of C (speed of light), this seems possible, but as an observer inside the cube observing the edge where any two cube surfaces meet the observer would observe the edge moving away faster than C (the vector)! so to me a cube doesnt make sense.

3. going on #2, the universe is a sphere with radius increasing at C ?

4. and to wrinkle the math some, if the universe itself is not expanding at speed of C doesnt this imply that light itself can indeed reach the edge of the universe? and if it does what happens?

just wondering....
