whoa ... note something here .... wait wait ... I need to do the math ...
dcl agrees with me ... and neverfly agrees with dcl ... thusforth neverfly agrees with me ...

did I do the math right?

There are times when I think that cosmologists are trying so hard to explain what they see, that they are forgetting that we don't see quite a bit.

It will have to wait until we can (technologically) make better observations but, I cannot help but think we are in for a few surprises.

Curvature of space :

Now can this mearly be an illusion as seen from our 3d perspective? Could matter blur the dimensions in a way where we observe a multidimentional event in a partial way.

For one thing, asking why expansion of the universe can't be a curved space-time is like asking why the speed of a bullet cannot be a tree. One is a property of an object, and the other is another object unrelated to the first object. You cannot ask why properties of objects cannot themselves be objects.

Why cant what we currently believe to be the expansion of the universe be caused by the curvature of space rather than new space being created.
