Major problem with time travel

Movies that feature time travel or even the general conception of the idea is like this: You retain your position in space and travel through time to appear at the same place in future or past. Here is my problem, did nobody else foresee this? If you go back in time and conserve your momentum( seems like a must) to appear at the same place, you will most likely end up in empty space or in a star because the earth, solar system, milky way galaxy fucking moves in space. With our current momentum we can't match Earth's motion through space and all travelers will die in vain.
Jumping in your DeLorean and appearing at the same place in future huh? No, you will drift in space with 85 miles per hour to eternity.

We are all traveling in time. The problem is one can travel only one direction. You can't travel in time because even minor change in past would make the fact of you traveling in time nonexistent.

Movies portraying physics inaccurately?  Well I never!

>>2
>>3
You are missing the point.

>>4
Yep.
I don't know about OP's post though. Since space and non-accelerating motion are relative, changing to another point in time like that might not conserve momentum the way we think it typically does

>>4
Missing the point?
It is like saying that you can't buy  2000 kg mouse (animal) because you don't have enough money.
The point is just nonexistent.

>>6
really visionary scientist candidate aren't you? anything is possible, laws of today won't stay same forever or for every corner in space. special relativity is theorized due to the assumption that causality is absolute, that result cannot precede reason. To me that is just a perspective, it is a matter of choosing what reasons and results are according to human perception. There will be a time where we can alter this and time travel will be just a trivial matter like computer games today.

you are dumb

>>7
you are dumb

Perhaps the time travel machine in question would merely choose the position in space relative to its own.  For instance, in Primer, it always placed the person inside the machine, thus making it impossible for said person to appear in space or anything like that.  I do see where you're coming from, but to say that a person will retain their same position in space as they travel through time suggests that your location in space has any significance or may be determined without reference objects.  It would seem, though, that you would retain your momentum relative to objects even as your direction through time were reversed, thus requiring additional energy to change your relative momentum to stay within Earth.  This is all assuming your could travel through time, though.  The mere act of accelerating yourself to high enough a velocity to change your direction through time would require a literally infinite amount of energy, and traveling through wormholes that have been located at different points in time would make this entire point moot.

In general, it's more effective to have your topic placed in the first post of your thread rather than the seventh.

>>7
You are a dreamer! You believe in magic! Relativity is very generous in terms of time precedence but it never contradicts cause and effect.
>>10
There is no wormholes. It is just a SF term coined to allow SF heroes to travel to distant stars fast. Wormholes are impossible if you consider problem of time and speed of light. If you came to some place before your light it would contradict cause and effect, not speaking of gigantic light impulse generated by you when you traveled and hitting you when you stopped.

incredible arguments, now i feel dumb dammit.

Time travel doesn't necessarily have to be through means of approaching speed of light. Well whatever i lost my appetite to continue
>>12
dreaming or magic has nothing to do with it. what we do today computers, electricity, a flamethrower is all magic to somebody from an early age. it is not universe that is limited, it is our minds that is not willing to exceed certain amount of chaos in the process of universe. Chaos is just fine, order is something we define anyway, only by perception we can find recurring patterns in actions thus define their boundaries. I really doubt human mind and thinking is the greatest interpretation possibility of understanding existence. Mind is most likely a result of a bodily/chemical function and expecting that to be the ultimate perceptive center of universe would be outrageously arrogant. We gotta take into account every possibility

it's kind of like with newtonian gravity, it works fine to a certain degree but fails terribly at explaining the details. i think relativity is even more dangerous because einstein was such a "respected" person, nobody has the balls to question his weird assumptions and everybody tries to build his theories around those of einstein not leaving too much room for new thesis'.

as an example, if i said that passing the speed of light isn't a biggie and the only thing that will happen is that i cease to exist because the matter i'm made out won't be able to interact with its surroundings, somebody will point me to time dilation and tell me that i should reread it while the predictions of time dilation are just as weird if not even weirder.

>>14
yea but i think you wouldn't stop existing after speed of light. it might be a threshold level for interaction with a higher dimension, as things are we can grasp up to 3 dimensions, time said to be 4th but i don't buy it. a new set of understanding might just arise after such extraordinary conditions. after all what consciousness and understanding is very ambiguous, mostly treated as abstract. i like to think that there is a mind field like electromagnetic field that interacts with matter if certain chemical complexity is achieved like the brain. that is the power to transform thoughts into actions that can govern and change matter. after the light speed it is possible to reach a higher state of consciousness, a new occurrence that will pale thinking in comparison. but that limit doesn't necessarily have to be speed of light, light just carries information fastest meaning it is the fastest interacting particle. there might be faster matter but interacting with them would be roundabout if not impossible

I thought everyone else already talked about this problem in 8th grade. Yes, it's an easily forseeable problem. A lot of writers try to come up with ways to make time travel seem possible, but you don't want all the pseudo-science or sci-fi explanations to take up time during a movie.

Moving with speed of light would require infinitive amount of energy, so you can't move with speed of light, so you can't move with speed faster than speed of light, so you can't travel back in time. How american one have to be to believe in time travel.

>>17
as i stated before you are so fixated on exceeding the speed of light. time travel is not necessarily related to your speed, time perception is already so ambiguous i expect it to be closely  interwoven with our understanding and way of thinking

>>1
The question is whether absolute coordinates exist at all in this universe. If not, "the current location" may not even mean anything when going back in time. If your current location is relative to something, why couldn't it be relative to the earth?

I would venture a guess that the problem with time travel is that it doesn't exist in a practical sense...and therefore is a waste of my time...which is probably why so many people wish and hope for it so fervently.

>>12
You're a fucking idiot. Do some research before talking about things you know nothing about. Sci-fi wormholes are very different from the wormholes predicted in theoretical physics. Also, from Wikipedia:

The American theoretical physicist John Archibald Wheeler coined the term wormhole in 1957; however, in 1921, the German mathematician Hermann Weyl already had proposed the wormhole theory, in connection with mass analysis of electromagnetic field energy.[1]

Actual scientific hypotheses existed long before the ideas started showing up in Sci-fi.

>>21
You fucking moron. You asskisser. You mother fucker.

Some stupid homo yankee and stupid homo german fagot say there are wormholes and you believe them. There fucking hundreds of scientists believing in ghosts and gods but still those things DO NOT EXIST you stupid masturbator.

>>22
wow, real solid arguments i am ashamed for all of us. i'm not him but wormhole theory is a plausible one and consistent with their explanations of dimensions. From a higher dimension you could create shortcuts in the lower one. To go from 1 to 10 in a 1-d numbered line, you have to cross all numbers in between. But from a 2-d space you could disappear from the line in "y-axis" and reappear at 10 without even meeting the numbers in between. So if you could reach 4-d you could create shortcuts in 3-d. Since they assume 4-d is time wormholes is suggested to be a way to travel through time but let's not bother with semantics. It is true time and space thus velocity are intertwined and that is why it will violate the laws when you travel a million light year distance in several minutes. But only for an observer from a 3-d world.

>>23
Dimensions?
Don't you think that after first 100 million years of evolution living organism would find way of moving in "other dimensions" if they existed to speed their chase after food or to run faster from predators? There is no more dimensions, and the three we know are not exactly distinct. There is one space but we think in terms of dimension because it helps us calculate vectors. Its only simple math. People who postulate "additional" dimensions need it to fit their inconsistent theories about subatomic particles to experimental data. BTW time is not a real dimension, it is just relation between causality and space.

>>25 and >>26
Now I understand. You are just a kid which tries to prove it knows something.

>>27
u mad? what you said is unbearably ignorant. answering it seriously would be humiliating

ITT: kids who know nothing about science pretending they do. See, I'm at least a kid who'll say what he doesn't know.  I don't know if time travel is possible, I don't know if wormholes exist (but I do know that they have been hypothesized by more than television), and I don't know how 3-d relativity necessarily behaves while traveling backwards through time.  Just....everyone attempt to use a bit of logic and refrain from using personal insults to prove your point.

>>21
This guy nor anyone else has said that they believe wormholes exist.  We have all just said that they have been hypothesized by actual scientists.

>>29
There is like about 100 million scientist living know. They hypothesized about everything, even about UFOs coming to Earth. It is not a proof that it has any sense. Many of them even believe in god!!!

>>30
you are lowering the discussion stage qualifications here. well every thread needs to die somehow, i guess it is you

>>31
maybe some arguments??????

>>30
"It is not proof that it has any sense"

You seem to be missing the point.  Not a single person has said that any of this has any basis in science.  We are merely saying that the theories behind this exists outside of sci-fi.  We are not saying that because a scientist hypothesized it, it is true.  We are merely offering up ideas for the sake of thought.  You can't say that because bogus theories have been put forward, any hypothesis is incorrect. 

tl;dr: "attempt to use a bit of logic and refrain from using personal insults to prove your point"

>>3
They took our JOBS!

>>22
and thanks to those Yankee homos and German Homos for giving me some imaginations that I can never follow up on. I appreciate it. :/

>>29
also, a hypothesis is a statement of the possibility of something existing, but is lacking in experience and further information.
Interesting that "Faith" is the pursuit of possibilities, wouldn't you agree? :/

>>30
I think you meant to say, "It doesn't have to make sense to be proof." often times Chaos theory is the impossibility or improbability of an event, nevertheless, an event takes place. In other words, a miracle.
It would be like the pope and a satanic witch getting together and having a child that became mormon later on. Who the fuck would have guessed or even attempted a guess at such an unlikely happening?

I bet no one here would even venture a thought about their own sanity. I bet they would all assume that they are sane. Would I be even remotely accurate in this assumption, knowing that it is just an assumption at this point? Alright, and what if I told you that everything this person knows is comfortable to him which is what seems to make him think that what he is doing is sane. However, this man might just as well be Jeffry Domher, but would he consider that what he is doing is insane?
Of course not? The joys of indulging in the deeds of comfort are comforting...for the moment...and when the moment passes? Back to square one, and projecting, rendering, and repeating for more of the same through habits and rituals. It is a complete return to animalism.
Spiritualism on the other hand, if studied in detail and depth, reveals something awkward about our nature. It reveals that all the supposed evils that man deals onto his fellow man, he had to also do onto himself in one sublimated form or another. And in the end, this man did nothing wrong. Every deed he does is a portrait of what it means to be human. However, to go against the animalistic human nature of being cruel and inconsiderate to his fellow man would appear to him to be insane and uncomfortable yet upon doing this the man would grow, adapt, and evolve far beyond what he had been in the past. When he would be normally faced with doubt, he could easily overcome this with, "It exists, how is the question." And in that sense, the scientist is born out of a spiritual man. And does this man have to be "all-knowing" in order to be considered intellectual and astute in scientific matters? Of course not! He is a human being! His origins are all that of ignorance and a striving towards awareness.

I would dare anyone to accuse anyone on here of being stupid, and that should be the very proof that this man would be the epitome of his own accusation.

I thank you for your time. :3

>>33
Oh yeah! Back to the wormholes on my hook. That is where you put the hook after all.

I have rarely heard about wormholes except in regards to an Einstein-Rosen bridges in regards to black holes and white-holes. I've seen many of sci-fi movies where this information has been exploited for profit. Hey, I'm not arguing, I'm just stating a fact of an event. The point is, there is money to be made on things that are real...and equally on those that are not. I dare anyone here to research and calculate the gross profits of fiction books vs non-fiction books; and equally, entertainment industry vs science industry. I guarantee you, it'll be a close one. The porn industry ALONE! And that's not even scratching the TRUE surface of humanity in the black markets and such.

As for REAL wormhole or time-travel science research. The only thing I've heard is that some scientists somewhere are using something that was able to put some piece of information at the opposite end of a table and the information reached that end before the light did and that somehow constituted time-travel, faster-than-lightspeed. That's about the extent of my research into this field.

Now, if I took what I knew JUST about this; I guarantee you I would have more information regarding this topic, who is researching it, who is funding it, to what ends they have reported they are doing it, and what possibilities this might entail.

As far as I've heard, it sounds like they are just trying to improve communications transmissions across the globe and possibly for space communications as well. But, then again, what the hell do I know, eh?

Is that sound enough logic for ya?

2250 "SINGULARITY" (all humanity disappears)

"bobbles"

DISTANT FUTURE

LAST HUMAN COLONY


Dewey: "The end of the world has come and gone. But there are survivors - time travelers from the past, brought to the distant future in time-stopping "bobbles". With luck, they might just be able to restart the human race.

Then Marta, co-founder of the colony, is murdered - left outside a booble to die of old-age. Wil Brierson, the last detective on Earth, has to solve a Whodunnit with the highest stakes of all.

Oh, and there's the little mystery of what happened to the rest of humanity.

And who bobbled Wil, tearing him away from his wife and children?

But first things first."

Did Marta's lover kill her out of jealousy?

Was it the Republic of New Mexico, the world's last democracy?

Or the family that wants to personally witness the end of the universe?

Or the Pearl Authority, who used Boobles to rule the world?

Or Della Lu, star pilot and Wil's investigative partner?
