There is some belive that the entire universe will eventually cool to absolute 0 (the so called heat death of the universe).
I wondered what was written on the Web about it and sure enough, WikiPedia has an entry about it that explains it more than I can.
Keep in mind, no one knows if this is a valid prediction and it is controversial.

There's no limit. Worst case is when all the stars die out, the universe keeps spreading out, and everything just keeps on getting colder and darker.
Lowest entropy was the homogeneous gas at the time of the Big Bang before gravity started making things get clumpy. That represented an increase in entropy, and it's been going on ever since. Newton was right.

What is the limit - add all energy and mass and that is the universal limit - then there is black holes with maximum entropy yet this is controversial on what this means.
There is research that proves there was maximum entropy in the big bang and there is low entropy in the past when the universe was a singularity.
Additionaly stephen hawking has reversed his support for the stand of blackhole containing entropy so basically humans still are uncertain in this area.
If your interested try researching yang-mil theories and supersymmetry.

The maximum entropy possible os embodied by a black-hole. The universe will never attain that level of over-all entropy though, because space is expanding quikly enough to eventually drive all galaxies away from one another faster than the speed of light, making it impossible for energy (or anything else) to be transfered between them.
I've never heard your Newton quote before, but I believe he is simply expressing that it is impossible to create anytihng with zero entropy (perfect crystal with no heat and movement).

Most entropy occurs when every particle is seperated by the next particle by an infinite distance, with no external fields. This could be the ultimate end to the universe after all the black holes have formed and evaporated by energy emissions, all the suns have gone supernova, etc. Dust to Dust, just very widely separated dust.

it really is a 2-edged sword. The credit bureau will look at it this kind: - beforehand you had a $2000 reduce and were using $1500 of it, this (assuming you've 0 different debt) shows that you're utilising seventy 5% of your accessible credit. in case your reduce were to strengthen to a $3000 reduce and also you're nevertheless using an similar $1500 you at the prompt are using 50% of your reduce. The credit bureau will be happier to work out that you're utilising a decrease percentage of your accessible credit. - on the different hand, your entire ability indebtedness replaced into purely $2000 beforehand while now that is $3000. The credit bureau will evaluate that added $one thousand as a plausible difficulty as that debt charge will now ought to "compete" with inspite of charge that you're making to a sparkling lender. commonly talking, it really is a sturdy signal that you're receiving a larger credit reduce. If not something else the corporate that raised your reduce has faith in you and feels tender which includes your credit worthiness. possibilities are extreme that it really is meditated in a larger credit status. word: once you've a large style of those charges (and specifically are branch shop or gas station playing cards) you need to judge paying off and shutting a number of them out. Dept shop credit strains are appeared at very otherwise from monetary organization-issued Visa / MC / Amex, etc.
