“evidence for an old universe and also a young one.”
Sure but 6,000 years? Come on, I am a Christian, not ignorant.
No, I didn’t say that the universe is 6,000 years old, it is obviously older, but, I am saying that time may not be what it once was. It may not flow the way it once did. The Bible talks about the Heavens (space) being stretched out like a tent, at the creation. Then, God rested from His work. After the fall, I imagine the universe has been steadily collapsing which would alter the velocity of light by altering the permittivity and Permeability of free space constants. (which may not be constant at all) If this is the case, since we reckon time by using the vibration of cesium atoms, by measuring the speed of light, we may be ensnared in flawed reasoning. Trapped in a frame we can’t imagine our way out of. The earth may have existed before creation in an accelerated time frame, in order to age it for our benefit. And once aged, perhaps pushed into normal space. After all, the Bible teaches that God holds the universe in His right hand. if the universe started out as a dimensionless singularity, which I suspect it did, Jesus, in human form, could do this— hold it in His hand.
During the tribulation, while the universe is being repaired, the heavens, or space, are said to “tremble”, and the sky “shakes”. It may be at that point that He re-stretched space out to its original boundry.
