We are here for X years then we die. Everything you see around you including us is decoration for the passing on of genes. Have a good time while you're here because that is all there is.
I agree, we only live for "X" years. But the important question is: how long can be "X".
X can become millions of years, or its limit can be simply undefined. There are many ways to extend "X" to become as big as you need.
- An obvious way is to accelerate your body to near the speed of light, but there are other ways that seem more interesting to me:
To start with something, there are two possible cases:
case_a) If your "mind" is something more than a neural network (or a natural machine), then it is clear that it may survive to the dead of your physical brain. In this scenery we do not know how it works, we only know that the "mind" is not linked to your physical body, "by definition".
case_b) Your "mind" is just the product of a neural network. In this scenery, we are near to a point where we will be able to create an artificial neural network with similar complexity than a natural brain. If Moore law continue as expected, and if our knowledge about brain workflow becomes completed, in a few years you will be able to transfer your natural "mind", both data and integrated functions, to an artificial machine, and then from one machine to another, as many times as required to live for billions of years, perhaps until the end of the universe. Technically, it is not forbidden. Even more, your mind could be improved by a million factor, it will be able to cover all the existing knowledge, and it could be mixed with other minds, or interact with them in different ways that we can not imagine today.
Both cases are equally interesting to me. We are at the start of a very interesting age, I only expect that my X will be big enough to see it.

AlphaNumeric. I remember I think a French guy about four decades ago who claimed that the body lost weight after death, etc. The trouble was that no one could back up his "facts" and I doubt that anyone remembers him now.
I can't speak for worms but when humans die, they usually get rid of all the air inside them as they do so (lungs collapse I suppose). This would account for a slight difference.
But as to worms, they need a humid environment. All the time they are out of it (out of the Earth), they are drying out, so losing weight.

we dont have the ability to answer such questions as the meaning of it all which leads to the questions mystery. all we have at the moment are opinions.
its like trying to learn something from a text book that has all pictures, diagrams and words removed. how can we be expected to know if all we have is a cover.
so my opinion is that we are in no position to answer the question. what ever the answer is we are in no position to change the answer (or maybe we are???). you just have to sit back enjoy the ride and what ever will be will be.
although the most compelling answer I have seen of late is the idea described in god's debris by scott adams

marc 1000. This is another immortality wish. People think they would eventually be able to have their minds downloaded into essentially artificial bodies and then live the best of lives forever, but what makes us who we are if down to our own bodies, their limitations, even the chemicals they release into our brains. Given time, if you were "downloaded", the person you were would eventually become lost as would your humanity.
As essentially a machine, you would never tire or grow sick, though you could break down. You would never know the pleasure of eating or drinking again. Probably never dream. Never push yourself to go that "extra mile" because machines have set limitations. Never love or hate or have any moods because your body would not utilise the chemicals that do this, so never be happy or sad. Never know love or have sex. Never have children. Probably you would see no need for friends after a time. We try to accomplish things now because of our short lives but if you lived a few million years, what's the hurry? You could learn a new language in a minute or two and do similar things but the best things in life have to be worked for. How can you appreciate something that is as hard as standing up?

The best thing any of us can do is hope to enjoy the lifespan we have here because it is all we have in this world. I know a number of people who died suddenly (often smokers) believing they had decades more to live. Death is certain so there is no point in worrying about it any more than worrying about paying our taxes. Live like you expect to make it to 100 and don't be afraid to enjoy yourself. Don't make too many anchors to tie yourself down.
If you are not married, don't rush into it. Plenty of time to see the world and do all you want to do rather than dedicating it all to a wife who will nag you and ungrateful kids who will take your money. Live life first rather than when the kids are finally gone and you're fifty-something. Whatever your taste, there are probably a few hundred million people in the world who will be "just the right partner for you". That is what love boils down to. Here in Bangkok I can pick up a beautiful twenty year old girl for half what I earned in one day.
Everyone has to go through pain and suffering at times. It is par for the course with our weak bodies. I have known many who died and cancer is one way to get plenty of pain and suffering. Half of all smokers die because they smoked, and if there is a hell and you go there after dying of lung cancer, you'll think you've gone to heaven. Smokers start dying aged 35 so don't smoke. It is a very costly way of committing suicide.
Life is ultimately what we make it. If you are in a dead end job with poor money, look for another one. The most successful people have often been those with nothing to lose so who have been willing to take a big risk.

There will always be more that we don't know, more mysteries, no matter much we advance in our knowledge.

javierxlxl. I am not sure you would age less if you travelled near light speed. The facts that atomic clocks with moving parts move slower when undergoing the rigours of acceleration and being knocked about does not mean it does. But even if it did, a trillion years voyage where we age only 50 years would seem like only 50 years to us (Sexton Blake pointed out similar in a story written some 40-odd years ago to the villain).
Also I think we could reach a point where chemical reactions have lost enough speed that they are no longer able to take place so all living things would die.

brupen. Most atheists were christians at one time but saw that god was wrong.
The bible is full of mistakes and tells us nothing about the world around us.
To not understand everything and so claim "godmusthavedoneit" is a defeatist attitude. Science still has a long way to go but has explained many, many things and proven evolution.
DNA or RNA comes from just four basic molecules so is nothing to do with lying statistics used by creationist sites. Maybe a dozen labs are working independantly to create artificial life from inanimate matter and expect results in 10-20 years. So, who needs god?
If you are going to talk christianity and more important creationism on a science forum, and not even in the creation/evolution zone, you must expect people to be critical of you and your beliefs.

Is it a wishful though to doubt that there are two different times;one for around a black hole and another for inside?
I am sorry but this disproves black holes on the spot. Light can always get out because there is no end to time. And if there is no end to time there are no event horizons. And if there are no event horizons light will always get out.

Light travels through space. We know that if you bend space (by gravity), then light which travels through it will bend too. If space is bent sufficiently by a black hole, then curvature of space is such that there are no paths for light to get out of a black hole.
"no end to time" is an idea and not a fact.
Escape velocity for a neutron star is 2/3 light speed. Why should it not exceed light speed when even neutrons are crushed to denser matter?
If there is no event horizon, then you have material at a trillion degrees centigrade. Brilliance of a star is measured by it's temerature. Our Sun is about 6,000.C on it's surface so appears very bright. How bright do you think something which is 1,000,000,000,000.C would be on it's surface? Such a light would seem like a searchlight even from the edge of the universe.

You are being just like Nick, but in reverse... you explain quite a bit for the existence of black holes, but you merely give your opinion that "a soul is impossible" without explaining why.
I would just like to point out that nobody in this thread has any clue what they are talking about when they pretend like science can prove or disprove things like this. There is no evidence one way or another, so why don't you stop pretending like you know differently?
----
Oh, and off topic, where did you get that idea that neutron stars have an escape velocity of 2/3 C? Surely neutron stars can be larger... large enough to have an escape velocity of 1 C, in which case it can form a "black hole" without degenerating into quarks.
To say with certainty that a black hole must be made of a material denser than neutrons, you would have to know the degeneracy pressure threshold for a neutron turning into quarks... and you obviously don't know that b/c nobody has ever been able to do it or see it.
In other words, have you ever seen a quark star? No. So why do you think a star can only trap light after it degenerates into quarks.
The threshold may indeed be before C as you are assuming, meaning that light will still be able to escape from any kind of neutron body, but there is an equal probability (with the evidence that we have) that the degeneracy pressure threshold may be after C, which means that a neutron body that is massive enough could trap light, and whether it turns into a quark body after that point can never be determined.

Latrosicarius. I have given reasons why a soul cannot/does not exist in a number of other threads. Here are some of them :
If you alter the brain in any way (surgery, drugs, impact accidents, etc), you alter the personality. No soul has anything to do with who we are.
We can effectively read minds in that we can detect electrical impulses in the brain and where they come from. Nothing to do with any mysterious soul. When someone dies, we cannot detect any brain or electrical signals from anything leaving the body.
We are who we are because of the brain's structure, the chemicals which feed the brain and the body and environment we live in. None of these would be present in/for a soul so you had a soul, it would not be you.
The soul is said to be totally immaterial so how could it hang onto a body? How could it record and store brain signals? What senses would it have since it cannot detect photons, sound, etc?
In thousands of years, no religion has shown that a soul exists. Science cannot detect one either.
A soul relies on a god and I have proven elsewhere that a god cannot exist.
Science cannot prove that Santa Claus does not exist which means by your logic that he must exist?

15th March 2007 - 01:29 PM
Latrosicarius. By observation, astronomers have set limits for neutron stars and black holes, what makes them, minimum masses, etc. I admit to not knowing enough to contradict astronomers as you are doing.
The mass, size and gravitational fields of neutron stars can be measured and they seem to be pretty standard, around 11 miles in diameter. A neutron star comes from a final mass of 2-3 solar masses. More than that and you have a black hole. There is very little room for manoeuver here and possibly a neutron star near the upper limit swallowing an Earth sized planet could collapse into a black hole from the extra mass. A black hole could be the fate of many neutron stars as they gain ever more mass.
Latrosicarius

kaneda,
I think you should re-read my post. You seem to think I was implying something that I was not.
About the soul portion... I was never making a defense for its existence. I was just pointing out how it is quite annoying when people say with certainty that it "definitely exists" or "definitely does not exist".
About the neutron star forming a black hole... Do you think I was implying something different? I agree with that, and I never said anything to the contrary.
All I was trying to point out is that once a neutron star exceeds the C escape velocity threshold, it turns into a black hole. BUT... It's STILL a neutron star on the inside. Nothing changes about it.
Of course, given enough mass, it may eventually transition into a quark star or further degenerate matter models, but ALL I was pointing out is that there's not unnecessarily anything different between a neutron star and a black hole other than increased gravity.
If you think I was saying anything different, please point it out the inconsistency because I was NOT trying to do so.
