Is time travel possible?

Two years ago, American actor Alan Alda challenged scientists to come up with a definition of "time" that could be understood by 11-year-old students. Alda's challenge was the second Flame Challenge sponsored by the Alan Alda Center for Communicating Science. The winners of that contest were announced in 2013. The winner of the 2nd contest's "written" category is Nicholas Williams, a retired scientist who spent 33 years working at Lawrence Livermore National Laboratory. Here is how Williams defines "time". Time has a lot of definitions; like time is history or time is age. But, have we ever considered a good definition? I have. Here'��s my definition. And no, I did not get this from some book or online. It'��s just something that makes sense to me. I think of time as Forward Movement.
Think about it! Everything moves forward, from the universe to every second of your life. And because everything moves forward, man developed a way to keep track of this Forward Movement and called it time. Man also invented clocks to keep a precise log of this Forward Movement in years, days, hours, minutes, seconds, and even parts of seconds. I'��ll always continue to think of time as Forward Motion. I'��ll also think of it as a Forward Motion that will never change, will never stop, and can never be reversed. The winner of the 2nd contest's "visual" category is Steve Maguire, a Ph.D. candidate in inorganic catalysis at the University of Ottawa in Ontario. In his winning video, Maguire defines "time" is one of the four dimensions and coordinates of space-time. One of the finalist's in the "visual" category is Dr. John Suchocki, an adjunct professor of chemistry and physics at Saint Michael's College in Colchester, Vermont. In his video, Suchocki states that "time" is a measure of change. He also suggests that the flow of time could be an illusion. * * * * * * * I do not see any conflict between the definitions of "time" given by the above-mentioned scientists. I will admit that the definition of "time" that I presented earlier is not correct, because "time" isn't specifically the measurement of the movement of celestial objects (although the definitions of "Year", "Day" and "Lunar Month" pertain to the movement of celestial objects). Yet, the movement of celestial objects is a kind of forward movement that Nicholas Williams mentions, a kind of change that John Suchocki mentions, and celestial objects have space-time coordinates, as Steve Maguire mentions. * * * * * * * Now, does anyone here have a problem with the definitions of "time" given by the above-mentioned scientists? Yes 'forward morion" sounds good; does the fact that changes have to always be in the direction of increasing entropy come into it also ? as we cannot totally reverse the effects of any previous change ? |

Tired but not sleepy, that's one difference now I am on my own I don't sleep easily, I always slept like a log when I wasn't on my own.

Dare I say something back on the topic...hmmmm...why not...really any relationship has challenges, regardless of age,...too big of an age gap could be a problem,...if he is 21 and she's 41...unless she ages gracefully it could be a problem...in 25 years...she may be retired and he would be still working...most men I know seem to be going pretty strong at 46...but most women at 66 are kinda not...hmmm...but love is a strange thing...my dad always said love is a meeting of two minds...in the mental world there really is no age gap...lots of smart young ones and lots of dumb old ones...and vice-versa... I totally agree with what you're saying but wonder how many 66 year old women you know, maybe you're right about 'most' women that age, I'm 62 and work out regularly at the gym. From my personal experience a person's lifelong lifestyle can have an enormous effect on their biological age compared to their chronological age - I'm sure I am fitter than most women (& men) in their 40s but that's also because a lot of people seem to totally let themselves go.  ... I can say that when I was 42 I dated a man who was 27 for a bit...we got along great for the most part...but It was really awkward in public...I bailed on that one, mainly cause mentally we did not click...no regrets.. Best wishes to anyone that wants to give it a shot though
People say I look younger than I did 10 years ago when I was working full-time and still looking after children. I'm retired from full-time work now and work for myself so have hardly any stress and I'm happier than I have ever been in my life - that makes a big difference to a persons health and sense of well-being. I now have time to go to the gym/swim & and try new things like weight lifting. One thing I'm glad I kept up is yoga, I've been doing it since I was in my early 20s and I do 20 - 30 mins every morning - keeps you supple :) I used to do belly dancing until a few years ago when I moved to VA & my teacher was in her late 60s - you should have seen her body - so toned & beautiful - I want to take up belly dancing again because it really is a great work-out. |

Interesting conversation, I may not meet a vegan on this site but I love the Physics - been out of the field too long to comment but thanks for motivating me to read up on it.

I was wondering what woman think of men wearing toe and finger nail polish . My sisters took me to salon for first time ever today . I thought it was great . Made me feel real good . At the end the woman wanted to know if I wanted polish on my nails . I said why not, and got black done on all my nails . I kinda like it, I might even like another color. I've been changing my attitude a lot more as I get older. I would like to know what you women think about guys that paint their nails Why not ? it's only a society norm for men not to wear it - personally it would make me take notice, although I think the colour might make a difference, black is neutral but red might be a tad OTT |

How many remember when cellphones were in bags? I do. My dad had one. Hehe. No, I don't remember bags at all; first one I saw in the early 80s was as big as a brick and nearly as heavy with an antennae about 10 inches long. Now I have the new iphone 6 :) How many remember when data input into a mainframe was done by feeding it with cards which had holes punched in them ? |

Whenever I am in the Countryside I often wonder what Cows think about as they graze away any ideas 
Maybe with all the environmental damage due to the meat and dairy industries they're wondering whether humans can think at all - don't believe me - watch "Cowspiracy" |

Does older women, younger men work out in the long run? I don't think age should matter if you find someone is your soulmate but obviously it depends on how big the age gap is, personally I would ideally like to be with someone my own age or a few years older - maybe irrational but that's how I feel. |

More or less I get it now. So a motion slows down the time, right????? Yet, is it speed, acceleration, or direction of movement, that slow down the time? What if you move millions times the speed of light (in theory of course), will the clock stop? and if you go even faster will it go backward? The faster you go the slower your 'clock' seems to be going compared to identical one left on Earth so twin in spaceship ages less than twin left on Earth. However the faster you go the more your apparent mass increases, so it's harder and harder to get extra speed (Force = mass x acceleration so as mass increases harder to force it to accelerate more) in relativity theory, the limiting speed anything could reach would be the speed of light ( c ) because as anything approaches this speed it's mass approaches infinity - well that's the maths anyway. However quantum effects seem to be propogated thousands of times faster than c & the Universe itself is expanding at a faster rate than c - interesting stuff but I doubt anyone (including the top names in Physics) really inderstands it |
