Time had a beginning.It has to be so.
If you missed it, last week I wrote NOTHING BECAME EVERYTHING PART I. You can see that HERE.
At some point, prior to creation, there was nothing. (Though this is where it gets confusing because prior to creation there was no such thing as "prior" at least not in a way of which we can make mathematical sense.) There was no time, no space, no matter. Then, suddenly, there was everything.
Don't get too worked up about "when" did this event happen. That's a debate for another day. The point is, it happened. Everything came out of nothing.
In future weeks I will talk about how time, space, and matter are co-relative. One cannot exist without the other. If we can show time had a beginning we can show matter had a beginning. If matter had a beginning, space had a beginning.
Today I'll focus on time.
The particular argument useful for this is one leg of the Kalaam Argument, associated with medieval Christian and Muslim scholars, but recently popularized by Christian philosopher William Lane Craig.
That leg of the argument goes something like this:
"The past couldn't be infinite because if it were, we would never reach today."
Think about it this way:
If the universe is one week old it would take 6 days + 1 day to arrive at today.
If a hundred years old: about 36,499 days + 1 day to arrive at the here and now (excluding leap years.)
If a million years old: 364,999,999 days + 1 day to arrive (again, no leap years.)
But, if the universe is infinitely old, it would take an infinite amount of days PLUS ONE DAY to arrive at today. Impossible. There is no such thing as an actual infinite.
Because we are experiencing "today", we know the universe had a beginning. Again, "the past couldn't be infinite because if it were, we would never reach today."
The Universe had a beginning and the Christian worldview maintains, "In the beginning, God created the Heavens and the Earth."
