Yeah of course they will...

The boys at the telegraph should lay off the crack pipe

I am not smart enough to understand any of this kind of stuff anyway but out of intrest how many here beleive its possible ?

Sure, why not.

Given enough time it's theoretically possible that time travel would become a reality.

I can tell you this though, if I was a time traveller I hink I'd spend most of my time trying to avoid the last couple of years like the plague (oh, and there's another period in time to stear clear of

).

A good dose of Manchester realism at the end:

Quote:

Dr Brian Cox of the University of Manchester adds: "The energies of billions of cosmic rays that have been hitting the Earth's atmosphere for five billion years far exceed those we will create at the LHC, so by this logic time travellers should be here already. If these wormholes appear I will personally eat the hat I was given for my first birthday before I received it."

Time travel into the past could be possible I suppose but time travel to the future? naaaaaaa how can you travel there if it hasn't happened yet. sounds daft but I know what I mean

What made it funnier was that I didn't have my glasses on when I read it. First pass I saw 'wombles' instead of 'wormholes'.

Come to think of it, that's probably more likely...

Yeah I get were your comming from but if it was/did become possible would'nt eveything become fu**ed ? I mean if people could time travel then they could change thing's no ? and if so well would we be here today ?

For me its very intresting but its very scarey to

Mikey845 · 11-02-2008, 08:33

I wouldn't worry about it, unless Doc comes back with his time travelling train I reckon your safe

Russ · 11-02-2008, 08:56

After getting 2 thirds through that article, my brain hurts

How big is the carbon footprint of these machines I wander?

Nobody knows for sure what the future holds, we can only predict.

Actually it's the opposite way round. Time travel into the future is not only real but many many people do it every day. Fly across the Atlantic and because you are further away from the gravitational pull of the Earth, for you time runs slightly slower compared to someone on the surface. When you arrive, in a very real sense, you have travelled a tiny fraction of a second into the future. Do the same thing around a neutron star and for you a few minutes might have passed but when you return to Earth, you could find yourself millions of years in the future with no way back.

Theroretically there is nothing forbidding time travel into the past but doing so can potentially cause so many paradoxes that many physicists believe that there will be some as-yet unexplained mechanism which will prevent it.

"Large Hardon Colinder"?

sorry

well I laughed out loud when i read the:
"The first time travellers from the future could materialise on Earth within a few weeks."

so if time travel is possible ever, would we not have seen something so far??? if they can time travel, then why come in the next few weeks?

and if time travel gets better, what companies will sell it? sorry sorry.
if time travel gets better, will they only be able to come back to the point where time travel was first used?
if so, then can someone from the future not come back with an upgraded version for them to use just now?
if they could time travel to the past, how do they get back to the future, without the power? (remember the flux capacitor was just in a film, its not true.....)

hehe

no matter what questions we have there is one answer I believe to be true......

no matter what (even dark matter

), Time travel is not possible........

time travel to the future was possible with concorde, but it is no longer in service

The effect is not limited to riding in concorde. (See here)

Anyway I digress.

Yes time travel of a form is already a reality, but it's hardly at a level where we have to worry about things like the Twins Paradox.

I wouldn't be surprised it 'proper' time travel does happen but the amount of energy to do it would be huge so I don't think it'll be done any time soon.
