Why don't people from the future come to our time?

Recommended Posts

Pure philosophically, the creation of the time machine will become true some day after reaching a certain moment of the development of science and technology. It simply does not have a chance not to happen.

 

Then why people from the future does not come to us? How do you think? What could be the possible reason(s) to stop the people from the future to come to our era? Can we think out how to change these reasons, and to make time traveling possible?

 

- Is it the reason, that it is impossible to be reverted the changes that the time traveler will made and something like the "butterfly effect" if inevitable?

 

- Is time traveling prove to be impossible after all?

 

- Will the going back in time be too expensive?

 

- Or maybe will be too hard?

 

- Or maybe the technology will be restricted only for use of future government and other institutions?

 

- Is time traveling an one way ticket - going once you can never come back?

 

- Is it necessary to destroy your body in order to come back in previous time?

 

- Or maybe the life in our time is so primitive, that nobody wants to have an excursion here?

 

- Or maybe after the transfer you may die or become an invalid?

 

- Or maybe time travelers exist today, afterall.

I think it's a matter of expediency. They could be all over the past, present, and future but have no reason to reveal themselves to us. Either that or they all got a lecture that went something like this...

 

"As you all know, one of our early chrononauts decided to go off mission, travel to various decades, and post on time travel forums all kinds of forbidden information. Anyone committing such acts will be EXTERMINATED before birth."

 

Did I mention Daleks run the future? :)

Thanks for the trailer :)

 

So...

There is something, that I can't understand. If they can exterminate the chrononaut before birth, why then can't prevent the postings of the early chrononauts?

That one is easy. They only do that with real chrononauts.

Doh! I should have suggested that at the meeting. Now we have to send other travelers back to prevent the exterminations. The past is just going to fill right up! Where were you next week when I needed you!?! ;)

Ha ha ha :) I hope, that I am not crazy. I am also not sure if the time traveling exists. It is a philosophical subject, that if there is not a scientific law, that not to permit a certain technology to happen, and if there are people, who are working over that technology, then the technology will appear some day.

In my bravest fantasy I have been dreaming about a technology to save lives by coming back to a certain event when somebody dies and to prevent the death.

The way I view that situation is it can only happen on an alternate timeline. If you go to that timeline and change something, how do you get back? If you do make it back, then the change you made will not have occurred on this timeline. And if you stay in that other timeline, then the other really big problem is that there are two of you now in that alternate timeline.

Sure. FTL is the only way to go backward along the same timeline. Not easy for a human sized object. Two entangled particles can be used as an on-off circuit. Changing the spin of one instantaneously changes the spin of the other, no matter the distance. This effectively achieves communication at faster than light speeds. Turn that into a radio signal and a message could be sent to the past.

To tell the true, I did not understand anything :) :) :) :)

 

So if I start from the present and go back in time, and, for example, I rescue soeone, lets say a child from a sure death (prevent a car to hit it from example), and I suceed to go back in the future... with the resued child ... then ... the change I made (the alive child with me) will not have occurred. And the child, that is alive now will be death? So it will come in the present death? Or it will be alive in the present and death in the past? I am totally confused :) :) :) :)

 

How about if you take the death body very fast after the death, or while it is dying and reanimate it and repair it in the future? The biological mass that has been taken from the past, can be substituted. E.g. a detah pig can be buried at the place of the death body. The reanimated or healed man/woman may remain in the future. Will this change the timeline?

Any change you make will alter the timeline supposedly. You already exist in all those other timelines. So there will be another you in any other timeline you travel to.

 

I suppose you could swap the body of a dead person for a live person and go back to your timeline. Or you could just stay on the other timeline with the decision to make on how to get rid of the other you, so you could take his place.

Well, I have no idea of getting rid of myself (the other me) and taking my place :) hahaha

 

So... only the swapping remains.

 

So...

 

I go back in time, rush to the child, that is going to be hit by a car, throw a death pig on the road, grab the child and dissappear back in the present.

 

Will it work?

DHS and FBI comes to mind. NSA Utah data center, totally now. Those groups track everything. They have time-watching technology at this moment with uranium oxide nano particle spheres. Potentially devastating tech. Fluorescent brain mapping, tagging, and tracking. Met a time traveler when I was a kid, he was a soldier, (so was his mom) he said the fluorescent tagging was a plague on health and was used up through 2040, researched to 2060s, taken out of practice 2080-ish after they noticed devastating effects on generations.

 

I've seen it in 2014 on a security soldier doing his surveillance, one of many on me, (who coincidentally was a model/actor for Liberty Mutual Insurance company magazine ads in Inc. magazine, what a novelty to notice that) a month or two ago when I was being surrounded by surveillance (the POTUS was going to be in town nearby and I'm likely classified a nutter/concern to gov't watch lists, so surveillance happens to me the day after every other nutter in the state has a meltdown/attack, and pre-government visits. It's a social stigma. Life goes on, I'm a pacifist regardless of what the neural-scopes at DARPA say! Silicon is typically wrong on carbon people anyways.) He walked into the restaurant, and he had in ELF-wave strata, sort of concurrent with WiFi in there, little eye-circle holes around him, and through them I could perceive his past/future (I don't know) of his perspective of where he walked as a soldier, with tan camouflage garb and helmet with camera, carrying a rifle walking with others, in a dusty town in some foreign land, middle east or north africa most likely. Then later I saw some online video of some former-government lady from Berkeley talking about depleted uranium rounds and uranium oxide nano particle spheres and I had the ah-ha understanding of what was seen. Poor guy was exposed to DU, the nano spheres have a density less than one, making a little time-warp bridge through his dna. Aw.

 

So yeah if I were a time traveler, I wouldn't visit this place either. Maybe some parallel earth where things didn't event quite the same way.

 

My nutter status being mentioned, I thought I'd mention that in some strata of time and space, to the west of the building where I live, there is some tripod device with a beam of light pointed at the window. Not there physically, but with cloaking/subspace/scalar technology, it may be there. Not sure who it is but every now and then it's two guys...I want to say they are Columbians or Cubans or people who look like that, but I don't know for sure. Well, anything is possible if time travel is possible, I think.

- Is time traveling prove[d] to be impossible after all?

Well, you can't actually prove that it is impossible. But that's not what researchers would be looking for in any case. They look for evidence that it is possible. So far we simply have no theory, none, that concludes that it is actually possible given the laws of physics in this universe. There are an infinite number of solutions to General Relativity that allow for time travel but they all consider well prepared "lab settings" and are based on physical assumptions about the state of the universe that don't appear to exist here.

 

That, of course, can all change if and when a theory is developed based on the world as it is. For the time being we're looking at centuries before we have the ability to make a practical time machine even if we do develop a workable theory.

 

And real scientists have to look at all of the laws of physics involved in a case for time travel. It's not enough to come up with a theory of how to warp spacetime. Once you have that theory you have to determine what actually happens in the region of warped space when you introduce all of the energetic fields that permeate space as well of the effect of introducing matter (a time traveler, for example) moving into the warped region. Hawking's "Chronology Protection Conjecture" is a humorous term that he coined but it is based on all of the full theories that have come up. Every time a time travel theory arises and is tested against all the laws of physics one or more of those laws throws up a barricade that prevents time travel. Then you have to determine how to navigate from A to B in a region of spacetime that is completely hidden from you behind some sort of event horizon. How do you get back? Can you get back? Do you travel in our universe or some other universe? If it's another universe refer to question 1 below - what is the purpose of time travel if the time traveler disappears into another universe?

 

Some big non-science social questions might be: what is the purpose of time travel; how much will several centuries of research cost; who will pay for the research; who will use such a device; how do you keep the technology out of the hands of malevolent people's hands given that the secret to the technology has to be kept hidden away virtually forever? We can't keep secrets for years, let alone centuries, in a world with no time machines. How do you keep any secrets in a time travel enabled world? You have forever to crack into the secrets and once you do then the bad guys have their own gadget.

DHS and FBI ... NSA ... have time-watching technology at this moment with uranium oxide nano particle spheres. .... Met a time traveler when I was a kid, he was a soldier, (so was his mom)

 

....

Tell me more about this time watching machine. What is it watching?

 

Why are you sure, that the man you met is a time traveler?

 

Well, you can't actually prove that it is impossible. .... So far we simply have no theory, none, that concludes that it is actually possible ...

 

... what actually happens in the region of warped space ... as well of the effect of introducing matter (a time traveler, for example) moving into the warped region. Hawking's "Chronology Protection Conjecture" is a humorous term that he coined but it is based on all of the full theories ....

So, noone can say, that time travel will work, but also noone can say, that it will not work.

 

What is the Hawking's "Chronology Protection Conjecture"?

 

These questions:

 

how to navigate from A to B in a region of spacetime that is completely hidden from you behind some sort of event horizon. How do you get back? Can you get back? Do you travel in our universe or some other universe? If it's another universe refer to question 1 below - what is the purpose of time travel if the time traveler disappears into another universe?

 

Can they stop a future time traveler to come to our time?
