When confronted by a new religion there is usually a dissonance.
The believer has a certainty in things that on their surface are completely irrational. Judaism began as a religion of animal sacrifice. Animals were deliberately killed in service to some god that demanded it. A bloody mess that has been dressed up into something less violent as human civilization has progressed beyond such ignorant superstitions.
I lived a long time before I was confronted by the religion of "no beginning". The religious belief that it is possible time has existed for "eternity".
When asked how much time occurred before any present moment the believer in the religion of "no beginning" says "infinite", as if that is possible. And they seem to believe it too. Like all religious adherents.
To model the situation with points and lines you can take any moment in time as the start and you can look at the simple consequences. This is possible if one is willing to do simple things.
Infinite time in the past would be an endless line extending from a point representing any present moment.
To get to that point would mean an infinite line was traversed.
A clear absurdity to those who just think about traversing completely a line that has no end to it. Or as the believers of the religion say: "Doesn't have a beginning". Same thing in terms of the ability to traverse.
I would like to begin an examination of this religion of "no beginning" with the idea of traversing an infinite line.
If there is a believer in this religion of "no beginning" that can explain how they imagine an infinite line, a line with no beginning as they say, was completely traversed I would love to see it.
How is it possible to traverse an infinitely long line? How does anybody believe for an instant it is possible?
This goes a lot deeper and it extends to the notion of progression. And the impossibility of progression with no start to the progression, but that is not the issue here.
All I want to understand is how some people think it is possible to completely traverse an infinite line. A line with no beginning as the faithful proclaim.
I would like to know the same.
If the universe always existed, then galaxies, stars, planets, life have always existed as well. But, it wasn't until humans appeared that the motion of bodies were taken to invent a measure called time.
If the universe has had a beginning, the scenario is similar, a nebulae which moved fast creating stars and planets and life. Plants and animals appeared, humans were formed, and after tall of this, humans saw regular motion of earth and celestial bodies an humans invented the measure of time.
Time has been always nothing but a measure and is finite because measures in the physical world are finite. Measures can be infinite only in the subjective, when we talk abstract mathematics.
In the physical world known as reality or better to say, physical reality, measures are finite or limited. We can measure the size of the universe limited to our resources, beyond what we can measure is simply "unknown", but the "real ignorant" called it "infinite".
