The fact that gravity/acceleration involves what is balanced inertia (and/or inertial resistance) is fully consistent with F=ma and E=mc2.
Time is necessarily possible/potential and actual on/in balance, as ELECTROMAGNETISM/energy IS GRAVITY. The fourth spatial dimension is consistent with time...
UNDERSTANDING TIME AND TIME DILATION IN CONJUNCTION WITH UNDERSTANDING HOW AND WHY ELECTROMAGNETISM/energy IS GRAVITY:
First, consider why and how it is that there is something instead of nothing. Now, we proceed !!!!
Consider what is the eye. (What is E=MC2 is consistent with wave-particle...
