Re: Why we can\'t reach the speed of light?
OOMBALA, Gee, I didn't know I had performed such a public service when I instigated this thread. Insomnia treatment, without a prescription, safe, fast, and effective OR maybe not if you made it all the way through. I just threw down a gauntlet, stirred the pot, and braced for collision. Hope you enjoyed the chatter.
The recent stuff I mentioned here regarding time travel might resurect the enthusiasm previously demonstrated when everyone seemed to have a chance to enjoy the light (there I go again) hearted debate.
The essential claim I'm passing along regarding time travel is that even if you could make a time machine it wouldn't go back before its own creation. What has been demonstrated recently by researchers that is so interesting is short lived and not effective for gross objects. What has been demonstrated leads researchers to think it possible to temporaly (not temporarily) decouple/desynchronize two regions of space, say for example, inside a room (time machine) and outside the room (rest of the universe). Time in the machine could be arbitrarily slowed to a small fraction of the external rate. After, say, 50 years, you could go into the machine and things would be as they were 50 years ago but the rest of the universe wold have plunged ahead as usual. Alternatively you could have stayed in the machine for a while and let the rest of the universe speed along ahead of you, time wise. After what would be a "short" delay as measured/perceived in the machine, the real world would have aged an arbitrary amount depending on time dilution of machine and duration of your stay.
You could for example, to borrow from the cryogenic life extensionists, put someone with a disease or condition into the time box with slow time and the disease would progress only a few seconds or whatever while centuries could theoretically pass in the real world and a CURE be found or techiques for "fixing" the patient. Unfortunately it is likely that the "survivor" would be a total liability to the future culture and would be at best a nusicence, trapped there unable to return to their own time or make a meaningful contribution to the one where they were now trapped.
Hope you get some sleep.
