There is a theory that time itself is not a constant, that the flow of time (when observed externally) flows faster at the beginning of the universe and slower as it ages. IIRC it's referred to as Planck time.

However this does not change 2 key elements:

1) it is not possible for us to observe time externally.

2) a year is measured by the time it takes the earth to revolve around the sun. Even if it used to be faster, the earth has still revolved hundreds of millions or billions of times around the sun and is, therefor, not 6000 years old ( for the creationist whack jobs amongst us).

The physical constants of the universe are not widely understood by the public at large, which may explain subby's confusion.  They're best explained through example.

For instance, the Planck constant is a measure of the 'free play' of the universe, which regulates determinism versus randomness.  The more free play in a system, the less order it contains, which can be illustrated by considering professional sports.  As no one plays for free in the NFL, the outcome of each game is completely predetermined, while in amateur unpaid football there is no logic.

No. A monkey would recognize that just because something evolves ,doesn't mean that a paralel track of evolution can't continue .

No, the Hubble "constant", is 1/tau, where tau is the age of the universe. So it is, of course, always getting infinitesimally smaller.

Then why do years seem to go by faster the older I get?

Every measurement is a direct interrogation of nature. It's a chance to sit down with the Universe and ask, "Did we get this right?" and "Do we really understand?"

That's not much of a direct interrogation.  I prefer to handcuff nature to a chair and hit it with a telephone book until it tells me what I want to know.

It's not strictly constant; that always made me chuckle anyway.  It's just statistically constant to any number of significant digits we ever expect to need. :-)

Because your frame of reference keeps changing.  When you're young, a year is a huge chunk of your life.  When you're old, meh, its just one more year of many.

I've actually got a strange videogame example...  If it doesn't show up below.

It's a empirical average.  We know of lots of galaxies that vary (usually extremely slightly) from the speed predicted by the Hubble constant because all matter has acquired some non-primal momentum (that is, not from the Big Bang).  Hell, the sign isn't even right for Andromeda.

Apparently there's a lot more sigma to this average than scientists thought, so either
1. the empirical methods and the assumptions behind them are incorrect, or
2. galaxies have acquired a lot more non-primal momentum than we thought

I wonder if dark energy fluctuates the same way matter does, and is causing some parts of the universe to expand faster than others. Would that cause this?
 
2013-04-17 04:02:28 PM
Blame the variances on Dark Energy and move along nothing to see here.

But It's okay, because they always have the speed of light to fall back on..

The reason there are still monkeys is that every time a monkey evolves into a human, a lemur evolves into a monkey to take its place; a chicken evolves into a lemur, a lizard evolves into a chicken, and so on down the line to the amoebae, of which there are trillions, so we will not stop evolving any time soon.

There was actually a Fark article on this not THAT long ago (or maybe it was ages ago).  Something to do with the way the brain works.  But I'm too old to remember shiat like that and too lazy to look it up.

The first year of my life took my whole life, the second only half my life.

Nowadays a year only takes a 40th of my life, they are just blazing by, faster and faster. so time is getting faster.

Also, when I was a child I had to struggle to get onto chairs, and couldn't reach the top shelves of the kitchen cabinets, but now I can reach them easily, so the universe is shrinking as well.

Scientists say 'mass' cannot be created or destroyed, if that were true, how can people commit 'mass' murder?

Checkmate, Atheists.

A very important distinction, IIRC.  The Jesuits seem to give more of a damn about people and progress than they do faith and dogma.

When you're young, years go by slower because you don't have as many years to compare them to. When you are ten years old, one year represents a much larger share of your life than when you are 50 years old.

If that makes any sense.
