No queer "fourth" dimension of time required.
Nothing goes faster than light, nothing goes slower than light. There is no time travel, there is no faster-than-light travel. Wherever or whenever you go in this universe it looks much the same as here.
We are all interference patterns written upon the light.
From the photon's perspective, the photons we are made of, there is no time.
We are all Star Trek, or otherwise mystical, creatures of "pure energy."
E-equals-M-C-squared doesn't mean mass can be converted to energy, it means that mass is energy.
Unfortunately things like bacterial and viral pathogens are pure energy beings too. You are a creature of light, but so is a flu virus. Sometimes the virus wins, hopefully temporary, but sometimes prematurely from your perspective dissipating your being forever by death. Consider yourself fortunate if you just feel like death.
Just as bad, inconveniences like broken legs, automobile wrecks, and bullet wounds, are also aspects of our human existence as pure energy beings.
Sure, you are a being made of light, 100% pure energy, but that doesn't mean bad other 100% energy things won't happen to you.
