The discussion centers on the nature of time and events before the Big Bang, questioning whether time began with the Big Bang and if it is meaningful to ask what existed prior. Mainstream theories suggest that time, as we understand it, started with the Big Bang, making "before" the Big Bang a concept without clear meaning. Speculation exists regarding potential influences or events prior to the Big Bang, but these remain largely inaccessible to current scientific understanding. The conversation also touches on philosophical implications of existence and causality, debating whether the universe's origin can be attributed to a cause or if it emerged from nothing. Overall, the complexities of time and existence before the Big Bang remain topics of intrigue and speculation in both scientific and philosophical realms.

Only that which exists can change - act or be acted upon. This means cause and effect is a FUNCTION OF existence, a derivative of the fundamental phenomenon of being. No phenomenon can be the result of its own subordinate derivative, so the reverse can't be true - existence is NOT a function of cause and effect.

Time is simply the measurement of change.

If existence is not a function of cause and effect, it is not temporal in nature. And since existence didn't "begin", then neither did time.

Entropy leads to heat death of our visible universe, if this is the future what is the past? Big bang is one way to "look" back to the beginning but how do "we see" it? What if you think of big bang as a single event with two directions of motion, in and out like a focal point, let's call this motion energy and visualize it as a black and white whole. After 13 billion light years I would expect these two extremes to still be visible as our horizons. I like to think that because we are inside of the black hole and all paths are curved is why we always see a vanishing point, and the outside of the worm holes formed when the white whole flew apart is what makes up our focal points. Matter is the past that I "see" and mass is the past that I feel and if you think of the world line of matter as always beginning at the center connection called mass then you will always look towards the beginning by "seeing" the past.

I tend to agree with Stephen Hawking's idea of before the big bang. Assume that the lattitude lines on Earth represent time intervals in the early universe. You would assume the big bang took place at the south pole, moving north (along time). So therefore, it is silly to ask what is "south" of the south pole, as it would be to ask what is before the big bang

Apparently the concept that the phenomenon of existence is not a function of cause and effect is not so easily grasped. Understandable, given the proclivaties of Judeo-Christian science and religion...but specious, just the same.

:-p LOL...OK...OK...so Time really DID begin. And the way it is going, it will probably come to an end very soon.

I would not assume time as moving in one direction only. I assume that time is more like a dilating point or area, with the latitude lines as the surface, there by making both north and south poles possible.

I assume that time is more like a burrito, with the tortilla as the surface, thereby making both salsa and avocado possible.

The difference between our examples says a lot about how we think. I see dilating light waves as the motion of time, why else would time be tied to the speed of light? I see these individual dilating areas, each emitted from a massive point, as a dilating image within my eye. These images make up my present, they are my future, but my past is anchored within this dilating frame we call earth. Your world seems to revolve around food. :wink:
