time travel

Re: time travel

That would make this thread pointless then. If it is possible, something would have happened already that would skew our past and there would be some sort of energy transfering or some way of interconnection like in the movie called "The One". None of this has happened so either it is illegal to time travel, they only made one possible device to time travel, or it just doesn't exist.

If someone could travel time, they'd be so advanced that it would be easy to blend in. Why would there be a need to reveal themselves heh, and if that branching theory is true, there is countless number of divergences and we are simply not lucky.

Re: time travel

I know one of my thoughts is true, there has to be a loop-hole on how time travel works.

How do you know? Heh all I am saying is pure speculation, theory. Call it what you will, I do not deny nor accept if it is possible or no. Because I do not have proof either way, but as far as speculation goes, there is superstring theory that make a heck of a lot more sense than saying that one of your thoughts is true, from the gut.

Re: time travel

Reach, the movie The Time Machine (both of the ones listed on IMDB anyway) are both based on The Time Machine by H. G. Wells, which was written long before the theory of relativity, or before people had put serious thought into the implications of time travel. So no, he had not changed the future. In fact the whole book was a commentary on the supposed eventuality of the gap between the social classes in Victorian England.

Relativity is useless here anyway. It talks about relative time. Noones really figured out anything serious on time travel anyway, because we still can't properly define it universally. XD

The newer time machine, I recall very specifically, he built the time machine to try to change the past, and it couldn't be done. No matter what he did he couldn't change what happened in the past.

So then he zoomed off to like 1,000,000 ad or something. And then some albino guy near the end tells him the future as it is exists because he created the time machine, effecting every event thereafter, and couldn't save his wife because he built the time machine in the first place; if he saved his wife the time machine wouldn't have been built.

So essentially -

You can't go back in time because the past is why the time machine exists in the first place.

You can't go forward in time because the reason it exists is because you built the time machine.

Makes sense to me actually. However yes, there is absolutely nothing solid on this topic. XD

Re: time travel

If the past was altered and the present cannot change, then it would skew 2 different time lines, making alternate universes. That, as we know, is impossible. Then if there was an alternate universe, then different energies would seperate between the seperate people that we represent. Time travel would then become illegal anyway for this purpose.

If it is possible, something would have happened already that would skew our past and there would be some sort of energy transfering or some way of interconnection like in the movie called "The One".

... what the **** are you babbling about? Have you even read this thread? What's this **** about the movie The One? Why are you people all quoting movies? Holy god, this is retarded. This is supposed to be the "critical thinking" forum...

Reach, I don't know, maybe the movie diverged from the book quite a bit, but I know the book certainly didn't have any of that. The reason I was talking about relativity was because that also meant that people didn't know anything about the whole speed of light barrier, time dilation, etc., and so hadn't actually needed to think much about time in terms of science except as a linear progression along which to measure data.

As for there being nothing solid in this topic - the theory of general relativity was the first to propose time as a dimension on par with our three spatial dimensions, a proposition which is now pretty scientifically accepted. I think this is pretty important in any discussion of time travel, because it brings up somewhere to at least start looking at it and reasoning about it.

Re: time travel

I suppose we have that as a pretty solid fact. Good point.

But I mean like, aside from time dilation, there are really no facts to support anything other than well...time dilation itself. Which I hope is the only sort of 'time travel' that will ever be possible XD

I brought up the time machine movie mostly because it uh, talks about the same stuff that has been mentioned on the last page or so here in a pretty good manner.

Re: time travel

Time is also perceived differently. For example when doing something interesting, it tends to pass quickly but when doing something boring. It tends to last a lot longer. I hate that part about it. ;p

So time that we measure via clocks is not accurate at all. Some hours are like 3 hours, some like 20 mins. I am guessing your time is ever adjusting regardless off the surrounding durations(time).

Some people live longer lives. Could it be because their time is different. I also know that genetics and for how long their cells possess ability to divide affect this, but isn't this also affected by duration?

Re: time travel

I see a little bit more clearler now. I now know that time travel does not exist for this reason. If the past was altered and the present cannot change, then it would skew 2 different time lines, making alternate universes. That, as we know, is impossible. Then if there was an alternate universe, then different energies would seperate between the seperate people that we represent. Time travel would then become illegal anyway for this purpose. I could make infinite skews in my entire life and I could even make myself king of the world.

THis Post and another one of yours talking about how time travel woould have already screwed up the present. If you look at them they sort of contradict themselves. If you say the present cannon change then why are you saying that time travel in some other universe would have screwed up our "present"

Re: time travel

Suzura metioned after the first post as how the present cannot change, and the second post, I stated how it would change.

This sounds like it would have more to do with memory.

If you spent an hour counting seconds, then it going to feel like a REALLY long hour because you were never occupied enough not to think about, and therefore register, how much time actually passed.

It's not time dilation. Time isn't moving faster or slower around you. If you were to wear a watch and synched it with a clock and they were different after an hour (assuming nothing changed the clock and watch, duh), then time dilated somewhere along the line. No matter how occupied you are, time passes the same (assuming you aren't moving fast enough for real time dilation to happen).

Re: time travel

Everything it matter and energy... and that is affected over time. No matter what, you would never be able to affect that matter in a way where it actually UNDOES itself, without giving off or absorbing energy, and that would mean that everyone would be affected by a time travel, being that the time travel wouldn't alter you, but everything else... or if you were to alter a single thing in a closed environment, how could you make grown molecules work backwards? The change of energy would always be so great, that the sheer impossibility, and the utter destruction of something would happen, before the time travel process could have started.

(Or so I would think)

Re: time travel

With our current means of generating energy...of course.

Zero point energy predicts something like 10^53 joules of energy in every cubic meter XD

Now if we could figure out how to use some of it.


And it's not really like we know how much energy teleportation/any of this would take anyway.

Re: time travel

Unlike in a tape recorder, though, events at one time influence events at another time instantly (i.e. because the tape itself IS time, there is no timeline along which to do anything to the tape).
