How long is a really long time considered?
415387
It is a relative term.  \n\nFor the Marine Corp drill Sgt who has just given a command...2 seconds.\n\nFor a student, concerned that the teacher will ask a him a question he can't answer...5 minutes\n\nFor a woman who has just found out she's pregnant...9 months.\n\nFor an old man...the next 5 years are longer than the last 80.\n\nFor anyone looking at ages....15 years older or younger\n\nFor a historian....a century or two\n\nFor a geologist....a millennium

All the time.  I would say about 5-7 days is average.

Question 1 - 7 minutes.  Other question ??  Sorry..

Depends really on how long it lives.

We don't know. People used to think it was 4 seconds, but now studies are showing it's longer. They probably run tests. But who cares for one, and two how do they know for certain.

too much!  lol\n\nprobably 35 -40 hrs

1 hour or 60 mins or 3600 seconds :-) is the time it takes but it will still be 12:30 :-p

An interesting question, which requires thinking carefully about how our common measure of time is related to certain astronomical (solar) positional recurrences.  A lot of people (though not all) have answered you as though the year were exactly 365.25 days long on average, but it's more subtle than that.  \n\nThere are in fact two particular "years" of interest:\n\n1. The sidereal year (period of the Earth's revolution about the Sun with respect to the stars, i.e. operationally, the time for the Sun to apparently "return" to the same position against the stars, after a "year" [crudely 365+ days], as viewed from Earth):\n\n365.256366... days.\n\n2. The tropical year (time for the Sun to cross the celestial equator [the projection of the earth's equator in space] again [e.g. from south to north] after a "year" [crudely 365+ days]).  Alternatively, "the period of revolution of the Earth about the Sun with respect to the Vernal Equinox":\n\n365.242199... days.\n\n(Both figures are quoted to an accuracy sufficient for our present purposes.)\n\nThese two different "years" differ by just ~20.4 minutes, owing to the precession of the Earth.  (One full precession of the Earth's spin axis in space takes ~25781 years.  This long, latter number of years is in fact equal to 365.25 or so days divided by the (essentially observed) "motion of the Vernal Equinox along the celestial equator," at the rate of ~20.4 minutes per year as just mentioned --- check it out.  [Sorry about the technical language, but this is technical stuff.]) \n\nIt's actually the tropical year that determines the rate at which the observed seasons recur, and since we want them to be "at the same time of the year," our long-term timekeeping is geared to the tropical, not the sidereal year.\n\nNotice that at 365.242199 days, this "tropical year" is just a tad short of 365.25 days.  That's why, instead of the simplistic idea of a leap year occurring every 4 years (and having an extra day that accounts "exactly" for 4 x the extra 0.25 days), there will come a time when we've overcounted a bit.  \n\nFor example, after 100 years, we should have had 100 x 0.242199 "extra days," or 24.2199 days.  The "one more day every 4th year" rule would give us 25 extra days per century, ~ 0.78 days more than needed.  If we could drop just 1 day then, that would be better --- but then we'd be under by ~ 0.22 days --- aha! --- close to a quarter of a day!  That's why the revised rule comes in that complete century years are NOT leap years --- UNLESS they're divisible by 400!  (Figure out for yourself from the 365.242199 figure how well this works in the long run.  I think you'll find that the calendar, on average, doesn't get a full day out of step with these revised rules until something like 3,300 years have gone by!) \n\nO.K., so maybe this is much more than you wanted to know.  However, with the right understanding of what the length of the year we usually measure is, 365.242199... days, then 1 million days is 10^6 divided by this, or 2737.90926... years, or 2737 years and 332.10... days.***\n\n*** Remember, this is a mathematically average result, for essentially perfect intervening TROPICAL years (to the accuracy given).  If you want to know it in CALENDAR years and a specific whole number of days, the answer will vary slightly about the preceding result, according to when you start counting. This variability is not just because of the usual "every fourth year is a leap year"  pattern, but also because of the way that century years aren't all treated in the same manner.  It's awkward to give a general rule!  \n\nLive long and prosper.

At one number per second, it would take you 11, 570,000 days, or about 31709 years.\n\neven at 10 per second you would need 3170 years, so, being a mere human, you couldn't do it.\n\nWill

I dont really know if they have recorded that. I would think that it could go for a long time.

Depends of the person.  Some people 10 minutes in my place is too long others could stay forever.

If it was a serious relationship involving love, there is no true time limit. It all depends on when your ready. I would say six months. You never know, but if you try going out and it doesnt feel right. You would know that means your not ready.

I think the limit is that if you turn in FORM1 in under the time alloted it will become a substancial limit of only 10 times in the matter of the time that was given....so good luck : )
