    Umm, Mars is remarkable similar to earth. It is a few Barr from having all three forms of water and people stille expect to find liquid water in aquifers on mars. The solar flux is well within the range that would support earth life. Mars is easily the closest planet to earth that we know of and in the past it was even closer.

    As far as computer viruses, it is VERY easy to "kill" them...I suggest a nice power button with a magnet on the hard drive followed by an install disk. In an overtly artifical environment, yes computer viruses are the closest to acting like life. Now tell me how a computer virus could arrise spontaneously....

    Even a sufficiently doped otherwise pure silicon asteroid bathed in solar energy wouldn't give rise to a "computer virus" and mars is not a sufficiently doped otherwise pure silicon planet. Therefore there is no reason to try and look for Computer viruses with the exceptionally limited resources availible on a Mars probe. Instead we should look for a life form that is even remotly likley.

    Actually, there are fairly good odds that alien life uses DNA in a similar way that we do.

    Primarily because proteins/amino acids are the only chemical family that has the variation needed for life to function. Sugars don't have the variety necessary and lipids have difficulty interacting with aqueous environments. the 20 amino acids we use cover the full range of conditions, acid/base/hydrophobic/hydrophilic/big/small/odd (proline). It is unlikley that other lifeforms will use significantly more or less amino acids even if the specific chemistry is slightly different.

    The biggest problem with proteins is that they can't store information. They can't form complements and unfolding a protein to directly read off the amino acid sequence typically destroys the original protein. Life needs a repository of information that is self correcting and is non-destructive to existing proteins.

    Since sugars and amino acids are common (sugar forms easily and amino acids are necessary for efficient life) it is not unlikley that DNA/RNA (which is based off of these two molecular families) would form and it DOES fit the bill for data storage. Since simplicity provides stability, it is unlikley that a huge number of different base pairs would be used so either 2 or 4 bases are likley. Due to space limitations it is very unlikley that a DNA/RNA system would use more than 3 hydrogen bonds and 1 hydrogen bond is too weak. Therefore the list of usefull base pairs drops to either 2 or 3 bonds and we call them adenine, thymine, guanine and cytosine.

    I freely admit that this is based off of an N of 1. But even with that said it is important to remember that life is hard and the simpiler/more efficient a system is the better able a life form is to survive. While the system we use isn't mandatory, it is very likley that it is representative of other similarly effective systems.

    A PCR system would be able to detect the residue of a lifeform that looks even remotly like us on a molecular level. Since we know our system works and we have no knowledge of a different life system it is only reasonable to look for a system we know works. PCR is our best bet for identifying life.

    Tell me that the next time your wife asks you "does this make me look fat". :-)

    You obviously haven't been married long if at all...the correct answer is "huh?" as you look aimlessly elsewhere :-)

    My point on lieing is that intending to mislead someone may salve a moment but doesn't help them in the long term. You never HAVE to answer anything if you don't want to. The truth is that everyone will die eventually. Lieing to someone to spare their feelings usually just helps keep them deluded and prevents them from addressing the problem...whether it is solvable or not.

    Now remember I use small lies like that as well. Honestly I just don't have the strength to be that honest with people.

    The original sin debate does rage on. The idea is that Adam as the original man is actually a representative of all man kind. However this is only a possibile argument if you aasume that the Adam-Eve story is just religious allegory and doesn't represent a true occurance. My stance allows for either allegory or fact.

    You're missing the point. I'm not trying to argue the morality of abortion one way or the other. Merely pointing out that honest people can have an honest disagreement about the morality ("goodness") of the act.

    Actually, I don't think there is any debate on morality. The debate is on the application of morality. Fundamental morality is very simple...respect for life and opinions. The question arrises when we try to define life or when opinions conflict.

    Let's say a woman has an abortion.

    If you follow the bible than she is doing nothing wrong. According to Exodus the unborn is chattel. If you kill the unborn you must repay the owner (Father in the old testament) but your life is NOT forfeit like it would be if you killed anyone else, even accidentally.

    I personally think that a fetus is as valuable as the parents decide. Some elevate the unborn on-par with a child. Others place no value on it. However once a child is born it has the same rights as anyone else. Unlike some other Christians, I follow the bible.

    And yes I more or less understand the concept of original sin and I do not accept it as the premise for any rational discussion

    Deuteronomy states that we are not to stone the son for the sins of the father nor the father for the sins of the son. Each person must answer for their own sins. While the original sin does provide an example of the sins of man, you and I bear no guilt for the sins of Adam. We are each born with a blank slate...sinless. It is for our own sins that we must answer and no one else.

    Why would a white lie necessarily be bad?

    The intention to miss-lead is a sin. Why tell the person "I don't know where my family is." when you could say "There is no way in HELL I will ever tell you where they are." I have yet to find a situation where a lie is honestly necessary.

    yes I have actually read the old and new testaments cover to cover

I AM a christian and I can tell you that I struggle with doubt every day. In addition God doesn't give a time frame for the prayer to be answered.

    Yes, the bible was set in a very violent time. Yes it offends our modern tastes. However I have yet to find a place in the bible where god did not warn people over and over again BEFORE bad things happen.

    The closest is Israel occupying the promised land. But did you notice that God didn't instruct the Israelites to hunt down and kill everyone who voluntairly left Cannan? Yes, taking the land (which had already belonged to Abraham in the past) was a mean (but not uncommon for all cultures) thing to do, but God did not order the extinction of the local inhaitants, only their removal. Only the people who refused to leave were to be killed, and they knew they could leave.

    I hope you re-read the "evilBible" and keep a copy of the actual bible next to you when you do.

    Actually, with the exception of specific conversations between two people, the bible has proven to be almost perfectly accurate.

    Archeology, third party histories and other evidence pretty much always proves that the larger events and geographies are accurate.

    -There are egyptian writtings that confirm the plagues.
    -Sodom and Gramorrah have been found and were both destroyed at the same time, having burnt down.
    -There is more third party documentation as to the life and crusifiction of Christ than there is for the life and death of Julius Ceaser.
    -Paul's exploits were well documented
    -the dead sea scrolls showend minimal historical drift in the text

    The list goes on and on.

    There are very few sections of the bible that are presented as fact when they may be religious allegory..the genesis story and Revelation are the big ones. Most other places the extraordinary occurances are events that DO happen (ie the plagues of Egypt) or are presented in dreams. But what I find so interesting about Genesis is that it actually does follow our current understanding of the creation of the universe, our solar system and the earth-moon system. I could easily beleive that a stone age man "receiving" an image of how the universe began would come up with a Genisis story from what he saw.

    The astonding accuracy is a result of the honor placed on the document. Most of the old testement was kept in the Ark and once every 49 years it was taken out and read in public then returned to the Ark until about 60 AD. This archiving maintained the original text without historical drift. Once the new testament was cannonized in the 4th century, it was maintained equally zealously. Monks studies for years to be allowed to hand copy the bible and do so with such expertise that it was impossible to tell the original from the copy.

    The reason conversations are necessarily excluded for the statment of accuracy is simply because there is usually no way to confirm or deny them. We only have Moses's word that a bush appeared to be on fire and talked with him. However we can reasonably assume that the text in the bible is the same text that was written 1,800 years ago.

    You really should actually read the bible. It is a remarkably good read and provides real insight into that part of history, human psycology not to mention religious theory.

    Umm, the average commute is 15 miles each way so the truck described would be fine.

    Now if the guy used something other than very low power density lead-acid batteries he would get better than 100 miles but that adds to cost. Plus I bet he doesn't have very good regenerative bracking if any at all. Current regenerative systems only capture about 10% of the availible energy. This is steadily improving and is mainly restricted by the batteries ability to absorb the energy quickly enough.

    A True EV will have 4 smaller motors, one per wheel. These will double as brakes and have efficiencies in the 90% range. The primary losses for this car would be wind resistance and cabin environmental controls. It takes the average electric car 100 watt-hours to drive at 60 MPH and about 250 to drive at 80.

    Actually there isn't much of an issue here.

    EV's will mostly be charged at night which is already off-peak. Therefore the current power grid can easily accomidate all the power needs even if up to 80% of all vehicles were electric.

    Plus since the biggest issues with power plants profitability is the disparity between base and peak loads, having electric cars raise the base load could actually LOWER the overall price of power.

    Plus it makes the cost of solar power MUCH more favorable. Over the next few years solar efficiency and electrical storage will increase dramatically. This makes home power generation even more favorable.

    By the time the current power grid can't handle the demand (in about 20 years) there is plenty of time to upgrade the system without strain.
