Let's say hypothetically, evolution is wrong...

I defined a micro-cycle. He defined a mega-cycle. It is the same.

And where do you get the data for the length of the cycle from?

So you will have different definition of day at different places in the solar system. What then is the day for voyagers that they are out of the solar system now? Would you need a local time system (a special watch?) if you migrated to the moon?

We're discussing days on Earth- it obviously varies for different planets.

 

[Ar Cosc]

It raises an interesting question though. You can define a day on any planet by the amount of time it takes to rotate once on its axis, how do you define it in interplanetary or interstellar space? Does it even have any real meaning?

It depends on where and when are you talking about. For example, moon, 5 million years ago, etc.

Earth's day is not always 24-hrs. It could be 10-hrs sometime ago.

Just like the definition of day, it is all about light and dark (or gray). That is where the meaning is. Time keeping would be the second purpose.

24 hours?

it would definitely have meaning in terms of any biologicals onboard -- their bodyclocks would still be operating in terms of that cycle, assuming that they are terran-derived. machine intelligences, not so much.

always need a frame of reference though, if for nothing else other than knowing when to put the coffee on

I have asked where do you take your data, not what is your data.

Data for "Day"? How about in a cave? Or, on the Mercury (by the new spacecraft).

I say it doesn't matter where you are in the universe, or how fast you are moving.

Day = one revolution of our home planet.

Day = one revolution of our home planet.

What if you were born on a dwarf planet?

 

[AV1611VET]

What if you were born on a dwarf planet?

In that case, 'day' would equal one revolution of our home planet.

 

[Ar Cosc]

In that case, 'day' would equal one revolution of our home planet.

So what word do you use for the time it takes for your dwarf planet to complete one revolution upon its axis?

Day

Day

Wouldn't that get a little confusing?

No

I'm not an Internet scientist -- I know what a day is.

What's an internet scientist? Somebody who studies the internet?

its like a internet bible expurt.

 

[AV1611VET]

What's an internet scientist?

Someone who doesn't know what a day is, can't tell the difference between something global and something local, thinks there was no life prior to abiogenesis, confuses magic with miracles, thinks one of the functions of Christianity is to hunt witches, thinks anyone but Matthew wrote Matthew (even though his name is on it in huge font size), thinks Israel was promised to them by anyone but Who they claim promised it, confuses the name of the Christian God with the name of an obscure German deity, etc. and so ad nauseum forth.

Somebody who studies the internet?

You, of all people, should know what an Internet scientist is -- q.v. your custom user title.

A scientist who only exists on the Internet ... thus, an Internet scientist, eh?
