It's funny. What is time?

Try to come up with a all-encompassing definition of 'time'. It's tricky

Also, since I see we have a few physics TAs here, one of my fav topics is the origins of the universe.

Discuss because I am going to bed.

THat has not happens and it also states that the world is winding down.....going from order to disorder....wonderful law really...and it has not been proven wrong since it was theoried.

the word time travel is not really correct. it's not as if time itself is being changed, but if a person could travel at lightspeed his time would move at a different rate than a person who is not travelling at lightspeed. read the other post i posted about travelling to andromeda.

Tenchnology will progress to massive degrees. But timetraveling is impossible. It just cannot be done.

DaveC is right....even tho....it would be kinda fun to go back to great dj sets you were at and relive them.

British Aerospace are currently testing an Anti - Gravity device which cuts out the whole taking a year to slow down shit....which means we fold space, and travel through. A scientist in russia said he had proof that he can and was doing it on a regular basis, and yesterday BA confirmed they are testing the technology...which is nice

Maybe the time travel will not be done using some kind of machine going at lightspeed... Maybe it would be done using our own brain! There are some ppl who got some perceptions of the future... Have you ever seen something in a dream that happened days / months / years after this dream? Maybe it's a kind of time travel...

= Now I'm totally confused =

A few things to think about here :


Ok so you can time travel ! how the fuck are you gonna get back for your sunday tea.

One your gonna be the most popular guy in the world but , guess what you aint there to see the people.

If you could time travel some activest is gonna kill you, sadam is gonna nuke you and the cops are gonna bust ya arse.

Are you gonna have the balls , the chance you life , your family just to try time travel.

you have just travelled back in time , but you can't get back and your gonna get pissed off coz all you have is dinasours to talk to .

if time traveled forward , your gonna be dead, coz you live to 80 max right if ya lucky, in time travel your gonna have to travel in light years, physically impossbile as your body will prob explode.

what happens when you go past Before Christ your gonna end in fukin hell, coz christ aint there.

if you go past the future you gonna end up in Microsoft land. !!

I personally don't think it's possible but these guys certainly hope that a lot of people believe it. http://www.timetravelfund.com/

lol. wtf??? there was life before christ u no. Christianity has only been around for 2002 years. Before that it werent all fires and ned flanders with hot pokers

im very surprised no one has mentioned the most famous reason time travel cant be possible, the "grandfather paradox". wot if u were to go back in time and kill ur grandfather as a child, before ur father/mother was concieved? u wud never have been born, therefore u wudnt have been able to travel back and kill ur grand dad. also, i believe that time itself doesnt actually go forward, but we are the ones travelling, so u cant go back through something that isnt linear, or something, that sounded much better in my head! read the michael crichton book "timeline" for the theories behind the paralell universe type of travelling, all to do with quantum foam etc. very interesting stuff!

i guess time travel will be possible only to go forward in time.. i think its pretty impossible to go backwards into the past.. but to go forward into the future is very plausible. we do it every day.
