Genesis 1 English Standard Version (ESV)
In the beginning, God created the heavens and the earth.
I've asked this before.
Some believe in a steady state universe.
Some believe the universe created itself out of nothing.
Some believe in this that or the other things.
With cause (defend your belief) can anyone come up with a reason for everything?
Using galactic counts the Hubble sphere has been estimated to have a mass-energy in the range of 1.5 x 10^53 kg, which is a lot of stuff, but apparently not much when compared to the size of the universe, in fact nearer a perfect vacuum than anything artificially created on earth. (Ref Quora)
But still if we consider E = mc^2 (energy = mass x speed of light squared) like all equations is reversible to (speed of light squared x mass = energy) then I suppose all that mass (1.5 x 10^53 kg), must have been produced by an awful lot of energy.
Assuming my layperson’s physics principles are correct we could propose that God shot a bolt of mega-lightening into the void which resulted in it being explosively converted into mass and stretched out across an ever increasing space time continuum.
Or it could be like a perpetual expansion and collapse, like this:
So we can look at it and say “well creation is simply a matter of being able to control sufficient energy to convert it into mass” or one could say “we just don’t know”.
