I think that is true -- using the technology we can imagine today. BUT what if future humans work on this in, say, 1,000 years or 100,000 years when the technology may be perfect? I think too many people think about things using short term technology and don't have the ability to imagine what humans can and will do in many thousands of years from now. Also, my idea is not to use atoms or any physical matter in the project, but to start at the "Starting Time" with the *structure* of all the brains and the parts of Earth (and maybe a larger area) that are relevant to humans and then use knowledge of cause and effect to figure out what the previous situation was. We are talking about tiny fractions of a second, the smallest possible piece of time as each unit as each section of this project. Where I think the problem lies, is the question - Is an exact duplicate of you - you? If someone could make an exact duplicate of the structure of your brain (and so you mind), would that duplicate BE you? We need at least two things to work to be able to rescue others from the past. 1. Cause and effect reproduction in reverse developed to perfection. 2. A duplicate IS the original to be true. We know cause and effect does work in the forward mode. David Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=31717
