Why a dead being cannot be revived?

Question

The scientists are understanding the human body since time immemorial but still they have not reached the point to make a dead living being live though they know how the different body parts work. The scientists have even able to create the duplicate copy of the living beings by understanding the genetical code. All the things that comprise a living body are extracted from the nature itself, but still they cannot fill in the missing thing to a dead body and make it live. Why didn't the scientists achieved this even on a dead ant (not to talk about human)?

Answer 1

Friend,

The missing thing is called Spirit,or Chaitanyam(Energy force)or Brahman that was in the body when it was alive...in fact this missing thing made the body function.
If you read some philosophical books ,it is explained there in a convincing way.For example in Indian Upanishads and in Yoga Vaashishtam (very elaborately in 32000 versus by Great RishiValmiki.)

Answer 2

Because in truth, we know very little about life. There are many challenges in trying to make the dead come alive. But I would like to point out that this has been achieved with viruses (sort of). You may want to see this link

There are also some viruses which can resurrect themselves on their own. Of course, some people argue that viruses aren't alive. Well, I would say that's just a semantic argument.

Hurdles:
1) DNA degrade very quickly after death
So if we can somehow correct the DNA in the cells, it is possible to resurrect the dead. There are some ideas floating around using nanotechnology to achieve this, but these are speculations.

2) Then there is entropy. Think about it. When something is dead, there is an increase in entropy. This is in accordance with the second law of thermodynamics. E-mail me if you don't understand this point.

3) Unless frozen, dead bodies decay quickly because of bacterial action. Which is why there is cryogenics, where dead people are frozen quickly using liquid nitrogen in the hope that they will be resurrected in the future.

There are more ...

Answer 3

Knowledge has nothing to do with it. Some things are simply irreversible no matter what you know. I could tell you everything there is to know about an egg, but that doesn't mean I can put it back together again once broken. I'd just have to grow another one. In physics there is recognized the concept of an "irreversible process" characterized by an increase in disorder. Disorder can even be measured in physics; it's called entropy. Death generally involves irreversible chemical reactions in your cells. Unless, of course, you're frozen. Then, all bets are off.

Answer 4

Doctors (emergency personal in contact with attending physician) are reviving dead people from time to time every day now a days. True, they just give it a try if it works it works.

It depends on lots of things, main driver is age of a person and temperature at which the dead person is kept at death, type of death, amount of trauma if a person dies by trauma..........and time since the death.

The other main problem is damage to the vital organs without blood supply to the organ due to temperature and other related effects on the organ.

Answer 5

Biology is one of the sciences that we know the least about. Most of the advances/gains have come about in the last 100 years. Thats one reason.

Freezing bodies in hopes of being revived is kind of a lost cause...water makes up a large portion of our bodies...water expands when frozen...therefore some very important cells in our bodies rupture when frozen, so don't count on it.

Answer 6

Death is the permanent end of the life of a biological organism.The principal causes of death in modern human societies are diseases related to ageing.Ageing makes the functions of certain organs fail.Science can replace certaimn parts but not all parts.

Answer 7

firstly... the true death of human is caused by "brain death". If any other organ dies... it can surely be made to function again nowadays...

but BRAIN in itself is too complex to understand and sorry we humans have still not explored all secrets of brains. and in my opinion humans cant ever understand BRAIN AtoZ.

welll if we ever could make a dead brain function... then we perhaps could make a dead body alive... and i just pray that never happen... cuz POWER in human's hands is never safe...

hope i helped

takecare

Answer 8

the body works to supply the brain with all it needs in turn the brain controls the body. If the body fails the brain dies.
the brain in extreme cirumstances shuts down organs to protect itself at the cost of the body.

Answer 9

Because we humans are not meant to be able to control EVERYTHING. I appreciate science, but have a great respect for nature and the thought of leaving some things to just "be".

Answer 10

because this "missing thing" that links a dead body and a live one is called a spirit...but scientists can't measure a spirit definitively, so they'll never be able to scientifically prove its' existence.
