I’ve read a lot about the topic of time. I’ve read that from a physicist’s perspective, there’s no real reason why time flows forward. I understand what they’re saying. That time for physicists is simply a part of an equation, and math is math, eternal and universal.
Time is an easy thing to talk about, but notoriously difficult to pin down once asked to define it. Time is the passing of … seconds (time). No definition that self-references is any good at all.
With that said, I think there’s some kind of equation out there that us poor mortals understand time. Now, I’m certainly not going against Einstein. And so, yes, time is relative. A second for me is different that a second for a GPS satellite circling Earth. Oh, the difference isn’t much. But it exists. They have be ‘corrected’ by 38 milliseconds (or maybe it’s microseconds). Anyway, time is flowing at a different rate.
So, here’s the thing. Time is related to the expansion of the universe, in my opinion. And so we could equate a unit of time to the expansion rate of the universe. Can we measure the expansion of the universe? I’m not sure, but I know we can measure the rate at which stars are receding from us. It’s from this data that scientists realized that the expansion rate is accelerating.
From what I understand, scientists believe this expansion is occurring everywhere in the universe evenly. It’s space itself that is expanding, like a balloon being blown up. Well, it seems to me that something is driving this expansion. If the expansion is just an aftereffect of the Big Bang, it would be slowly down or at least maintaining a steady rate.
Now, if my theory is true, then we can examine what happens to time, relative to me standing on Earth, for someone circling a massive black hole. Well, time would slow for them. If that person rejoined me on Earth, he may have aged one year when I aged twenty! But, this is where it gets interesting. Because a massive black hole has a whole lot of mass, which works against the pressure being applied by whatever is driving the acceleration. And so time passes more slowly.
A similar argument could be made for someone traveling near light speed, again relative to me. That person gains mass. And more resistance. And time passes more slowly, relative to me.
I’m certain that Einstein’s right. Time for us is relative. But that doesn’t mean we can’t have a good yardstick to measure that relativity. Let’s use the acceleration of the expansion of the universe to come up with a yardstick.
