Why Does Time Fly?

Yes, the "Dark Energy" may exist but still more usually if the theoretical model do not fit with the experimental observations then this difference is called "error".

Well, I used to Google to find forums with cosmology issues and I found some interesting discussions from your forum. So I decided to muck in and do my share to arise discussion and really I got quite much feedback, many thanks.

Yes I agree "time can be measured as events change", however, what you mean with rate of 10^-43 secs ?

What is Dark Energy? Has it been tested?

Yes, there are many more cheerful explanations for my primary question "Why Does Time Fly?" than I was able to invent. Especially "Time is fun when we're having flies. - Kermit the frog" describes the situation clearly.

it's a theoretical energy that we can not see (i'm not sure if we can observe it or not, someone else will answer that) but it accounts for a large percentage of our universes mass.
and if i recall correctly, if you use the balloon-universe analogy, the inside of the balloon would be dark energy.

i learned all of this from this forum, if it's wrong-sorry. i'll learn from my mistakes again.

I have understood that "Dark Energy" is only the difference between the semi theoretical model and experimental observations. Usually this kind of term is called "error".

I feel annoying that many cosmologists seem to be so confident on the current ideas inspite of the lack of the experimental evidences. It seem the be too easy to hide behind the complicated mathematical models and dimensions.

Yes but the theory that includes Dark Energy postulates that it represents more energy than all the normal matter in the universe, so its way beyond "error."

Its the measurable effect countervailing the gravitational forces of normal and dark matter. Its quite measurable, and both dark energy and dark matter have been shown to have locally non-homogeneous distribution. Now what it *is* is open to speculation and hopefully successful theorizing eventually, but it is there...

Time is as a tool to pinpoint the approximate start of an event and to measure its duration. Time is not static -- there is no "moment" in time and no specific increment to define it. Linda
