There shall be a resurrection of the dead, both the of the just and unjust. -- Acts 24:15

"Very truly, I tell you, no one can see the kingdom of God without being born from above." -- John 3: 3-9

Among all biblical teachings, resurrection from the dead is probably the most difficult to accept. Everyone knows that, after death, the body will decompose into molecules and NEVER recombine to form the original body. Then, how could there be "life after death"? How could anyone be "born from above"? What does the resurrected body look like? Will it include anything that represents the person before he dies?

According to the string theory, we are confined in a three dimensional braneworld that is embedded in a ten dimensional world. We have assumed that the higher dimensional world could be the "Kingdom of God". There is a natural mechanism that prevents us from seeing anything outside the braneworld. This agrees with Jesus' teaching that we cannot see the Kingdom of God while we still live in the terrestrial world. However, Jesus went a big step further to tell us that we may enter and see the Kingdom of God after we are dead and "born from above". 

In 1 Corinthians chapter 15, Paul spent quite a few words to explain "how are the dead raised up? and with what body do they come?". He said "It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body." Thus, the natural (physical) body does not go to heaven. When a person is raised to heaven, it will be in the form of a spiritual body. 

Which part of the person will be included in the spiritual body? According to the string theory, all matter that constitute our body cannot leave our braneworld. Therefore, your legs, your heart and your brain cannot go to "heaven" (the higher dimensional world). Some people may say "the soul can go to heaven". However, what is the soul? what is the physical definition of the soul? where is it located?

Physically, the only thing that can identify a person and also possibly go to heaven is memory. Although memory is stored in the brain, it is not matter. It is a kind of "information" that is not confined in the braneworld. As an analogy, the information you receive from a website is stored on a server (a special kind of computer). The server may be confined in a room, but the stored information can be transferred to other places.

We do not know what the spiritual body look like. It may contain some "organs" that fit the higher dimensional world. Our original organs cannot, and does not need to, go to heaven because they are designed to fit the terrestrial world. These organs cannot represent a person anyway. To construct a spiritual body that represents a person, God may simply retrieve a person's memory and integrate it with some kind of "spiritual organs".  Interestingly, one of near death experiences is "life review" - a playback of memories. The life review could be the memory transfer process from a physical body to a spiritual body. Further details are given in the next article.
