expands everywhere more or less evenly...moves in addition

There cannot be expansion without motion....motion (inception towards death) adds expansion (life).

you are in the center of expansion

Indeed...center (life) of expansion (inception towards death) during motion.

speed of light is a constant

Speed implies measuring of ongoing motion by temporal matter from within. Light as constant implies before setting itself apart into a visible spectrum that can be measured.

nothing could move faster than light

Slow vs fast implies a conflict of reason aka measurement issue among rays within visible spectrum of light...not light itself.

Few trick many to measure while ignoring that each measurement aka each ones measuring mind is a fault within result.

could not lose energy

Lose energy into what and where? Energy implies all internal power aka both loss and growth in balance with each other, hence all being one in energy.

current expansion is one-way process

Current (inception towards death) expands (life) during a one-way process...internally/inherently.

And on top of that it all covered...

All reveals each one...one chooses to cover self by ignoring all (perceivable) for each other (suggested). Consenting to a suggestion puts oneself at bottom and another on top.

be completely different

A being cannot be complete...only a partial (matter) within an even (momentum) whole (motion) aka within the process of differentiation.

Few suggest progressivism (complete) to tempt many to heal the world by bringing together (tikkun olam) aka to complete that which is broken.

preserve current

Current moves...motion cannot be preserved. Prime example...currency. Many are tempted to hold onto currency; yet it miraculously flows out of their grasp...again, and again and a gain for few.
