Do you think that it is possible to back to the past? Any scientific reasons? 作者: lodin 時間: 2009-1-30 07:47
Long time ago, I was reading some magazines and one article mentioned that scientists thought that worm hole could be used as a time tunnel to go back to the past.
I don't know the exact details but they claimed something like blackhole and worm hole were kind of inter-related. 作者: Godman 時間: 2009-1-30 13:27
Send the "whole human body" back to the past is very difficult.
I am thinking, just send "message" (EM wave) back to the past will be much easier.
If we can send message back to the past, lot of wonderful things we can do! 作者: 紅綠燈 時間: 2009-1-31 00:31

I always wonder if it is possible, why I haven't seen anyone from the future?作者: 小神 時間: 2009-2-4 07:36
Well, the most heated way is that build a machine that can accelerate so rapidly that the speed or velocity can exceed the speed of light...
When there's a machine that can go faster than light, then we can possibly go back to the past of future by the relativity, but then it's not feasible for human body, coz the heart cannot withstand the high pressure generated by the high speed. So, lots of problems arises =[ 作者: cyc@@ 時間: 2009-2-4 09:11
Unfortunately, according to Einstein, no matter or information is transmitted faster than c
So let's wait until we've got some new discoveries or theories
