  • CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Ask a physicist anything. (5)

Three cheers for science :thumbsup:
Science serves to prove that when you are dead you are always dead, right?

( no... more.... life......! lights out ! :doh: )
Science is the systematic acquisition of knowledge. This includes the knowledge of death (what constitutes death, how to know when an organism has died, etc).

But God serves to prove that when you are dead you are always alive. Right !
Unless you've died, how do you know what happens after death?

As for badtim's comment, I think he was just pointing out that the feeling you ("I'm still alive....!......I....Feel......GREAT !........

") is the same feeling people experience by taking LSD.

I haven't died yet, therefore I cannot answer that question.

I haven't taken LSD, therefore I cannot comment on that thought.

Once you die, you die. It is not possible to be a little dead or a lot dead. Dead is dead.

The answer is when someone dies all that happens is that you cease to exist in the sentient way.

I had a similar experience; I died for about a minute (well not dead exactly because my brain was still alive). All that happened was I switched off. No dizziness, No fading away, No transition to anything, Nothing! I plainly just ceased to exist.

There is nothing to fear about death. I know that it is hard to accept that when you die you cease totally to exist in any form. Enjoy life while you have it because one day you will be no more.

No heaven, No hell, no angels, zilch!

Funnily enough, a few years ago I went on a course called Medlink- it was an invitation of many doctors to come in an present to us their fields in medicine, as I wanted to (and still do) want to become a doctor.

One of the doctors was with the RAF and his job was a sort of paramedic, part emergency doctor. He saved a man who had a lorry turned on his head, he saved a man who had been under water for five minutes unconscious, and he saved a three year old girl mauled by a dog and thrown around the kitchen.

In other words, he saved many people who were 'dead' but brought them back to life. His definition of dead is to have your head seperated three inches above the body (he can work on you if its 2.5 inches!), and he jokingly said that he sometimes tries to revive corpses only a week old when he walks through grave yards!:)

OK I have a goodie. According to uncertainty momentun and location of electrons cannot be measured at the same time. But does this principle necessarily still hold for QM as proposed by string theories, or is the uncertainty at experimental level resolved by an appeal to certainty but within higher dimensions which we cannot observe.

Please feel free to explain to me what happens after death. ! :confused:
The physical body decomposes. The concious mind ceases to exist, by all appearances. But you haven't answered my question.

No; the uncertainty in QM is inherent to the premises upon which QM is built. QM tells us that certain variables are inherently related (position and momentum, time and energy, etc), such that measuring one necessarily blurs the other. For string theory to do away with uncertainty principles, it would have to overhaul QM - which it may indeed do.

The idea of a vibrating string doesn't seem very uncertain to me. It must be a very simplistic popularisation.
Indeed. 'Course, quantum mechanical uncertainty is unrelated to the colloquial definition.

Your answer sounds like it's posted by a "Lazarus" heh heh.
