Why do we need to see gravitation as force?

[Dex]

why cant we see it as dimension like time?

 

[Nabeshin]

Gr aviation is an effect of the topology of dimensions, but not a dimension in and of itself. To try and describe it as a dimension is meaningless.

Also, I'm not sure we see time as a dimension either. Many people still have a hard time dealing with a 4-D spacetime picture of the universe. So, it's certainly not something intuitive.
