What do we know? We..... I am not sure, but I know that 2+2=4, to start with, and that branches off into a bunch of stuff. I know that if I jump out of a plane without a parachute, the landing will not be nice.
I believe that God is the creator of all things. And I do mean all things. That includes time. If one "creates" time then by definition, they are without time.
The phenomenon you are talking about is called "time dilation". It is common in life threatening situations. It is the brain allowing a higher percentage of its "power" to a specific thing.
This same process that the mind goes through, assigns a hierarchy, if you will, to a set of variables.........it assigns importance through proximity, movement, color, and other learned factors, such as if someone has a gun, or there is a fire.
An example of this is the old video of the kids dressed in white, throwing a red ball, and you count the number of passes between the kids. All the while, a black gorilla, walks right across the screen, and it is invisible. Sure, if you watch the video now, you will see the gorilla, but the first time, nearly everyone, 99%, do not see it.
Correlation is not causality, and although sometimes it can seem that way, more times than not, the truth is either more simple, or more complex than correlation would have one suppose. Of course this is not always the case, but in more in depth topics like this one, it is important to know the processes.
The above is taught, and trained against with many fighting forces that operate in urban terrain, or in buildings. It can mean the difference between life and death.
