Can you tie this together for me?(adsbygoogle = window.adsbygoogle || []).push({});

My understanding:

If something does not have mass, it does not interact with time. If something has mass it interacts with spacetime. When mass interacts with spacetime, and creates gravity, it may travel through n+1 dimensions.

My questions:

A.Time is considered a dimension, right?

B.If so, does light only "travel through"/"interact with" 3 dimensions (x,y,z)?

C.Does mass "travel through"/"interact with" one more dimension than that?(x,y,z,t)?

D.Is it possible that gravity completes the pattern and "travels through"/"interact with" one more dimension(n+1)?
