There is nothing like a concise, logical, consistent argument!
Some things you cannot put a figure to, no matter how clever or concise you want to be, for example E=MC2, the only thing we might perhaps know is the speed of light, so Do you know the concise quantity of E and M ? so how much substance is in the universe and how much energy is in the universe?
And I said perhaps for the speed of light as it is again not concise, it travels at different speed through different materials, substances, and you measure it against time which itself is not constant, time slows down as you speed up, LOL! so how can you measure time or speed of light? concisely! do we not say that speed of light is constant, even if the observer was himself travelling close to speed of light, he will still see speed of light as quoted by mathematician/scientist, he won't see the differential speed. i.e. the difference between his speed and that of the light!
In Physics we were told that light travels in straight lines, for most practical purposes it does, but when you get to large scale, gravity bends light! Astronomers use this phenomenon and call it a gravity lense!
Gravity itself is one of the properties of Energy or God.
As for time or speed of light as a constant Einstein used, I am not sure if time seizes to exist when an object attains the speed of light, may be it does, in other words when an object acquires the speed of light it simply seizes to exist, and hence for it time becomes non-existent or zero! perhaps it converts/transforms back into Energy/God. which are in timeless bound. Who knows? I am not a physicist but i can throw some wild guesses and probabilities or possibilities.
