Hi All, I get that one object can't travel faster than light with respect to another object because of SR and length and time contraction. What I don't get is how this meshes up with expanding universe. If the space between 2 objects is expanding then wouldn't two objects be accelerating away from each other at a pace which would eventually exceed the speed of light? Yet my understanding of SR says this isn't possible. Does this mean there is a limit to how fast the universe can expand with respect to any observer? Please help, thinking about this is making my brain short out. Oh, and I realize the above questions are yes/no questions so if you could also explain that would be helpful. Thanks!
