If Time Travel Will Ever Be Possible...

GregoryNimmo

If time travel is someday going to be possible, couldnt we make a sort of target date for the "futurenauts" to travel back to?

Like all the world leaders agreeing that next monday would be the date that if ever in the future time travel becomes possible, they travel back to that date and inform us?

Do you get me? :P

There was something like this in “The Big Bang Theory” comedy show. The two main characters were signing their room mate agreement and one of the clauses in it was that if either of them were ever to discover time travel in the future they would agree to travel back and appear right at the moment of signing the contract.

However, if it helps, there are many ideas out there for how time travel might be possible such as establishing a singularity using massive amounts of energy etc etc.

However the issue with most of the theories I have heard is that time travel would only then by possible backwards from any point in the future to the point when the first singularity was established.

So if we want to know if time travel is possible we would have to first set up this singularity, which is currently massively beyond our expertise at this time, and then see who or what comes out of it.

That they could arbitrarily travel back in time to some point like next Monday however, is something I have seen no theories to support as yet.

Hwaking speculates that you can only go back to the point the 1st time machine was invented.

Think about it, every day we exist time could have been changed in our past and we wouldn't be aware of it anyway.

We'd need to revise the language somewhat. It would be wrong to say anything like "the time machine was invented on that date", since someone could use it to go back and invent it on an earlier date. Neither can we say "it will be invented in the future", since that could be changed "later". It either exists already ... or it never did and never will.

Stephen Hawking held a reception party for time travellers in the last year or two. He didn't send out invitations until after the event, but he gave exact time and space co-orinates for the party. Nobody showed up, shockingly...

That's what I said he said...... *tut*

Time is seen sequentially, as a series of events that are leading toward something: beginning, and an end. In Newtonian theory it is something absolute in reality, regardless of human perception. According to Steve and Newt time exists and we pass through it ergo we are all time travellers.

All be it travelling forward in time. Backwards is a different kettle of fish….

Time travel into the future is theoretically possible.

If it all goes to plan, I'll be back in a few mins with Wednesday's Lotto numbers!

Surely if travelling back in time was ever going to be possible, we would already know, because people would've come back and told us..

That's my totally unscientific perspective.. :P

Surely that would then be a duet ? I won't call you Shirley again btw.

but time travel is so complex...


for example if i could go back in time, i would be stuck between a rock and a hard place,

there are many things i've done that i wished i could go back and fix, but then if i fixed them would i have what i have today? probably not and i wouldn't want to lose what i have, so my problem begins, i guess im glad im not aware of time travel...


at least that way the decision is made for me,as much as i would love to i can't change a thing.

Of course time travel is possible. I'm from the future. Watch, I'll quote a post which hasn't happened yet...

Er.....how will you come "back" ?

If what you say in the first sentence is true, the best we could hope for is that you "disappear" until Wednesday, and we meet you there (then) with the Lotto numbers.

That's not much good!

I get you.

I was about to post a thread entitled 'Define yourself......philosophically, of course.' (And naturally, due for posting in the Philosophy forum, before it was moved.)

Time is such an integral part of our defined reality. It is, at best, an epistemology; based (presently!) on misleading and inaccurate ontological observations.

J.W Dunne (IRISH!) – ‘An Experiment With Time’ - approaches 'Time' from a scientific perspective, with surprising results.

I'm not implying that the above book is a bible for all who want to decipher the mystery of time; however, it is (was) the only published investigation into the phenomenon by a truly exceptional mind.

The struggle between creative thought (consciousness) and ‘defined’, empirically based theories (consensual ignorance) continues, since time immemorial.

Thought provoking question OP!

I would go back into the future.

The future hasn't "happened" yet, so there's no future humans available to travel back to us.

lol who would believe someone that claimed to be "from the future"

that person would be locked up or laughed at, unless someone physically proved time travel noboby would believe them and imo the only way they could do that is by transporting you or another doubter into the future/past

It's a small price to pay.

We'd need to build a time machine for time travel to happen, I know that's obvious but that's the only way people from the future will visit us.

It's like a telephone, you need 2 receivers to be talking to each other.

TeddyTedson

If you do travel through time though you start getting nose bleeds and die so that's why people don't do it.

Why would you want to go back in time? Its stupid.

I hate all this nostalgic stuff. Nothing would change.
If I did wrong, why would I go back in time? I'd just apologize now.
If I told a lie... I'd just tell the truth now to right things.
If I broke a rule... I'd own up and not do it again.

Live for the future, its a hell of a lot better.

I think that if someone invents a time machine they will be fine if they use it to just jump forward however far into the future, but as soon as they travel into the past they will change the events which led to them inventing the time machine and not invent it.

It's not just theoretically possible, it's a fact of life.
If the GPS satellite operators didn't take into account that time is passing slower for their satellites than it is on the ground (therefore they are actually traveling slightly into our future) the GPS system wouldn't be as accurate as it is.
Gravity and velocity affect the "speed" at which time passes, the faster you travel the slower time passes relative to a stationary observer.
Near the speed of light 186,000 miles a second, time almost stops.

Time, or at least its perception, is marginal.

Just fill your Delorean with a splsh of vitamin Pu and you're all set for a trip into the future. Once there pick up a Mr. Fusion Home Energy Reactor and from then on you'll be able to run your time machine on everyday garbage.

I keep my time machine working by feeding it printouts of AH threads.
