Nothing can travel faster than the speed of light. (the observable universe is 46 billion light years wide, started at a single point, and is 13.7 billion years old,,,hmmmm)
Nothing can travel through space faster than light. But the expansion of the universe isn’t an expansion in space, it’s an expansion of space. Space can expand faster than the speed of light. This does not violate the lightspeed limit within space.
In other words, nothing in the universe can travel FTL but the universe itself is expanding FTL.
If you work out the math, matter past the edge of the 'known' universe (which must constantly be accelerating, in order for the expansion to remain constant) is already way past the speed of light. We may never ever be able to 'see' the entire Universe, for that very reason.
Now, if the Universe is 'infinite', then the speed of light is constant.
Mull that over a little.
I wonder if it possible to expand space within space.....
Damn, where’s my bong...
