[@michaelscott7916]

I don't think 'traveling ' through time is possible. There are way too many variables involved. Every action a human or any animal makes effects his second to second existence . I did this (cause)& this was the result(affect) & there are 8 billion people on our planet making decisions & taking actions or making decisions & NOT taking actions all day, every day, nanosecond by nanosecond. This literally creates our reality unless, like some sci fi material such as Westworld has speculated, it doesn't. That free will is mostly an illusion & that humans are so predictable that if given the opportunity we would all make the same decisions, & make the same actions over & over & over again with the same predictable results or affects. That there are actually a few moments in each of our lives where we really do have free will & the ability to actually change the outcome of our futures but we mostly blow it because we either don't sense the moment or if do we simply make the wrong decisions. Michael Crichton wrote a book called Timelime a few years before he died that was very interesting. Yes , there was a movie adaptation . No, it's not good or really faithful to the book at all so don't judge this from that movie .Definitely would recommend you read the book though. This is actually possible(in theory) & though not technically time travel it may be the closest thing to it that humans might have a shot at achieving one day.

[@JustDoIt12131]

It's funny that you say time is an idea. If there is a single thing that it's clear that exists outside our brain that we are aware of, that is time. It's like "I think ergo I exist", but actually correct: that "I" is ambiguous because we don't fully know the nature of ourselves. But that doesn't happen with change. If we perceive that things change, something MUST be changing. Probably not what we perceive, probably not as we think it changes, but definitely something changes. Whether it's just "movement" or an alteration of a state. Because if there were no changes at all in the universe, the phenomenon of us perceiving anything would not be possible. The only thing that we can be sure of is that change exists. Time exists.

[@Jeff-fd8sc]

​@JustDoIt12131 Would it then be right to say that time as we call it only exists because we observe change? Change is constant of course, but we have to label and characterize it somehow to place it in our reality. Isn't that where the idea of time itself originates?

[@ontheroad5317]

I have always had a big problem with the concept of time travel. And it isn’t the traveling part that’s an issue. Let’s say it’s a given that we can now travel through time. The real problem isn’t WHEN we “land”, it’s WHERE we “land”. In movies, they always assume the point that you’re standing on the earth is the constant. But in order to successfully time travel, you need to calculate exactly what point in the UNIVERSE you will re-appear. Considering the earth is rotating at something like 1600 km/hour at the equator, and rotating around the sun at 107,000km/hour,and the solar system is moving about 700,000km/hour. Plus the galaxy is shooting through space. In order to do a simple time jump of, say, 10 minutes into the future, you’ll need to calculate the exact point in the universe where your feet will be 10 minutes from now. And it’s not a straight line, it’s a complex, spiraling, corkscrew path through space. And suppose your math is off by a few feet/a meter, you could arrive half buried in the ground, or floating in the air, or inside a tree, or any number of other gruesome possibilities. The calculations would be all but impossible. Unless you are time traveling by magic. Then I have no argument.

Only so many elements / molecules provide the characteristic to be a building block (carbon is tetravalent which means it can bond to 4 atoms at once). Energy needs to be absorbed and emitted in certain ways as well, so I'm sure scientists are looking from a more general perspective such as "what is producing these odd energy patterns, it could be life", rather than looking for a planet that specifically looks like Earth. Carbon and silicon can form solid structures within a certain temperature range for example, so they probably look out for factors such as that. I still agree with the fact we have no idea what alien life might look like, but at the end of the day it is still bound by the same chemical and physical laws of the universe that we are.

It's only 4.4 light years away, but it would still take us 6,633 years to get there at our current fastest speed of 450,000 MPH. And even if they knew we were here and just wanted to send us a message, depending on where they are in the galaxy, even that could take thousands of years to get here. It's a false paradox imo.

Countering the Fermi paradox, if you look at the time line of the earth's existence and specificaly the total period of time that human life has existed on earth, it is a tiny blip in time over the time line of the existence of our universe. So potentially we may have came to existence after other intelligent life ceased to ocupy our local area of the universe, or other intelligent life may not be evolved yet locally to us, given how big the period of time the universe has existed so far and likely to continue.

Kevin Brooks that's interesting . Once you wrap your brain around the incomprehensible size of the known universe & the time frames involved its an idea that's started to gain some traction in recent years. You know there's really only a couple of movies that takes this concept & runs with it & that's Forbidden Planet & the original Alien especially but just as a standalone film without considering the prequels at all. What essentially happened is that ship really just stumbles into a scene from some kind of cosmic nightmare that is supposed to have played itself out a long, long time ago. Unfortunately for the crew of that ship one small piece of that nightmare is still alive. Finding the remnant of some long dead civilization is, in many ways, more realistic than straight contact and Alien really capitalizes on that fear of the unknown factor better than anything still out there

When it comes to paradoxes in time, i have seen it done beautifully in one series so far "Steinsgate" How to save someone life without creating a paradox in time? Lets assume that we travel into the past (lets say 5 years) so save someones life that died 5 years ago. How can you save that persons life without creating a paradox in time? Stupid as it may sound, its very simple: Save that persons life, without letting anyone know that they didnt die. The events traveling their death have to transpire the same way, and the person has to remain "dead" until you reach the point in time you travelled back from. After that the person can reveal themselves as everything hence forth wouldn't create a paradox anymore, because you never reached that point in time before travelling back in time and up until then, everything had remained the same as you have known. you could either simply bring the person "back to the future" which would be the most failsafe way of doing things without creating a paradox, or make sure they dont effect the timeline in any way during the time of their supposed death. As long as the records stay the same up until the moment of time traveled back from, nothing changes. this sounds logical to me anyway. However, there is one good counter argument though: Time is not owned by humans, meaning, just because we dont know about something happening or not, doesn't mean the universe isn't aware (as stupid as it may sound) The person that died in the original timeline did not disappear from the universe. the particles the person was made of still remain in the original timeline and in one way or another effect the original timeline, as minuscule as it may be. and the absence of that effect of the timeline may cause a paradox in itself. ... or not, who knows. this shit is so complicated, ill go watch some mark wahlberg movie

It would also explain why quantum physics are so strange and different than normal physics - because the beings running the simulation have to impose limits to prevent us from being able to determine that we are indeed in a simulation. (Limits like the our fragile planet with limited resources, our delicate bodies, the hostile environment and vastness of space, the one-way linear flow of time, the speed of light, not being able to find any black matter despite it making up most of the universe, never being able to reach or see anything beyond 46.5 billion light years from Earth or beyond the event horizon of a black hole, or anything smaller than an atom, only being able to experience three dimensions, only a rudimentary understanding of how quantum objects exist in multiple states, quantum entanglement, etc., etc.)

I lived in a rural neighborhood in the forest in northern AZ as a teen and went on many hikes in the forest. To find artifacts left over from the native or wild west cowboy camps I would have to dig down to find them because they were buried from time passing. Trees dropping pine needles, wind blowing dirt, rain burying things in mud, etc.. I would clear rocks off the area before digging down to find the artifacts. If the artifacts are from the past 150 years or so, why are rocks that are millions of years old sitting on top of the ground above them? Many too big to have been blown there by the wind. Shouldn't the rocks have long been buried in time? I would find large and small chunks of petrified wood sitting openly on the forest floor, even though it's surrounded by pine trees. Shouldn't it have been buried under pine needles and everything, given how old it is? Some you would think someone just put there a week ago.

One problem with communication over interstellar distances is just that. The time it takes for radio signals to travel from one star to even the nearest makes it very impractical. Also, the ability to detect signals that have dispersed through space and over the inference in space makes it exceptionally difficult. Look at the Viking probes. If we didn't know they were there and exactly where to point our radio dishes it would be virtually impossible to detect their weak signals. Most civilizations out there probably use some focused beam tech to communicate which would make it almost impossible to intercept unless you happen to pass through the beam. So unless they come to our planet, it's unlikely we could ever find them by looking for random radio signals.

But we dont know of any such material yet

Its matter. First you must ask yourself where are all the photons coming from? From the light source they are blinking into existence. So if photons can appear into existence they have the ability to disappear just like they appeared in the first place. In a 4d universe, objects will appear and disappear to our eyes because our brains cant process what a 4d object looks like. So maybe theres a bigger picture to what light/photons actually are.

The Observer's Paradox / Schrodinger's Cat Box always struck me as less an exploration of quantum states and more an exploration of the learning limitations of our observation-based method of scientific inquiry. Those who take the paradox literally are suggesting that reality doesn't coalesce into certainty unless it is observed, but doesn't this suggest some sort of nigh-magical power on The Observer while simultaneously undercutting the idea that the universe operates based on consistent, demonstrable principles? After all, if we believe that reality only becomes fixed when it is observed we imply that all unobserved locations and materials are inherently unpredictable and could do or be anything until an observer comes into play -- the irony being that, if the unobserved universe were truly so fickle, we'd have abundant second-hand evidence of the chaos it would unleash, which we don't. This kind of thinking, it reeks of the kind of limited humanity-centric medieval mindset that gave rise to ideas like Spontaneous Generation, Humors, and Miasma. The idea that the cat exists in both states at the same time is ludicrous, and I strongly suspect that all the "serious" scientific theories that stemmed from it will ultimately be set aside as our observations and predictive modelling improves. The Observer Paradox, as far as I can tell, is just an outlet for people who never fully wrapped their heads around the early childhood concept of object permanence. Prove me wrong.

There may be a flaw with schrodinger's cat paradox. The scientists are assuming that the cat won't interfere with anything inside the box. The cat is unpredictable.

[@LandonBradford-p4t]

your missing the point and the paradox, my guy

[@Molden-Mat]

I also think scientists are assuming that the cat won’t interfere with anything inside the box. The cat is unpredictable and may try to escape, scratch the box, or tamper with the apparatus. This may affect the outcome of the experiment and invalidate the premise of the paradox. In fact, some interpretations of quantum mechanics suggest that any interaction or observation, even by the cat itself, could collapse the superposition and determine the fate of the cat. The Von Neumann-Wigner interpretation does talk about this. The cat's state was already determined before the observation; it's just that we didn't know until we looked. I could be wrong though

[@vshah1010]

The universe has the built in property in the present such that time travel cannot change those events. You create a time loop. It will always be just out of reach and you have to make the same decision. Also, in a time loop if something has happened in the past, it has always happened (e.g. you did not change it). But, the universe's built in limitation does not take away from free will. Conduct your life to allow for possibilities if you ever suspect you might be in a time loop. The movie "Triangle" does the time loop well. Although in that movie, there is another copy of "you", present "you" cannot interact with past "you" in any way that will change the future. I believe time loops are finite and they are usually short time periods. You probably won't realize if you are in a time loop.

The solution the observer paradox is that when observed photon interacts with the photon received by our eyes changing its behaviour , this is also the reason for the wave function collapse and heisenberg,s uncertainity principle .. Now , where's my noble prize ?

[@patchesdf]

I think the problem with the double slit experiment is not the photon. It doesn't care if it's being observed. The problem is the observer. We are not capable of observing paradoxes. So when we make a deterministic observation of that this photon is up to, from the observer's POV the wave collapses. In according with the theory of parallel universes, the interference pattern is still there, we just don't see it because making that observation, coupled with our inability to observe paradoxes, only allows us to see one outcome.

[@tristintaylor7999]

I like that thought process

[@theunhappygamer1744]

I agree with you, only change I would make is that I personally don't believe there is a paradox. We only see a single outcome because we are apart of this universe. I think its probably much more simple than we are making it out to be. I think that anything that can happen does happen in another reality and when we observe the photon we are interacting with the photon causing it to show the outcome that was always going to happen in the reality of the observer. In fact the experiment may prove the exsistance of fate.

[@neilangus4401]

Correct Nice comment

[@LiteShaper1]

But what is the mechanism that causes the wave function collapse? A “deterministic observation” in the context of the double slit experiment should have no effect on the photon. In fact you can leave the measuring apparatus in place and just scramble the results with a computer preventing which way knowledge and the wave function is reestablished. I think the key here is when you say “from the observer’s POV”. Reality itself, as in a space/time matrix with locality (objects with actual location relative to the observer that are collapsed out of just potential ) maybe manifested by a sublime interaction with a form of consciousness more fundamental than space/time.

[@theunhappygamer1744]

​@@LiteShaper1 Its the interaction of the detector that causes the waveform collapse. Well you can believe what you want but I don't personally believe a consciousness is required. Science had to at least consider the possibility a hundred years ago when quantum mechanics and the double slit experiment were still young but the vast majority of scientists have long since moved on.

[@AdrianLParker]

The double slit experiment is not a paradox. It's an example of how the wave-like properties of particles affect the environment

[@titirititiri6360]

More like how our intentions affect the wave function as an observer, when observed there is a collapse in the wave function, “Brahma sitting on a lotus opens his eyes and the world comes into being, Brahma closes his eyes and the world goes out of being” observation is the act of creation thru inherited thinking

All paradox are are simply our inability to comprehend, failures in our understanding. Fact would not include any paradox. We invent paradoxes! Is time travel even real? Yet we invent a paradox on something not based in fact but mathematical equations, human constructions! The only valid paradox here is the double slit and like the others I think it's due to our limited/false understanding.

[@olivierdastein2604]

@@waylandsmith235 The cat paradox is totally valid, it's only very poorly presented here.

[@olivierdastein2604]

The paradox is very poorly explained. The gist is that what you describe for the coin doesn't apply to a particle decaying. Its state is undetermined until it's observed. Not undetermined in the sense that we don't know, like for the coin, but actually undetermined, like a coin that would stay in the air and never land until you'd look at it. Or rather that would land on both sides at the same time and only "pick" one when you look. That is established at the particle level, but the paradox is : what if the state of the particle had consequences at a macro level, like for instance a cat dying or not depending on whether the particle has decayed or not. We know that the particule is in an undetermined state having both decayed and not decayed, until we check. So, is the cat as well in an undetermined state, both alive and dead until we open the box?

[@randomgreyalien4835]

Well, I think that we are not the only living species in this massive and immeasurable space, and here's why. It is estimated that there are more than *100 billion planets* in our Milky Way galaxy alone. It is also estimated that there are more than *200 billion galaxies* in the *"observable"* universe. So if there are 100+ billion planets in one galaxy, how many planets do you think are there in 200+ billion galaxies? Now, we never sent probes to gather data on all those planets, so why would we assume that we are alone in the first place? That being said, I think there is a very high chance that there are lots of civilizations out there, but we are just too far apart to even make contact. And if these civilizations are too advanced, why would they seek us out? We are currently a type 0 civilization. Any civilization above type 1 would never care to contact us because we are inferior to them. At the end of the day, we really have no idea how immense the universe really is. There is a huge probability that there is an infinite number of galaxies, since it is said that the universe keeps on expanding. So, can we really say that we are the only living beings in this vast and unexplored unknown that is the universe? Are we really that special? Don't forget, we are only talking about the observable. We still don't know what lies beyond the observable.

I think the reason why aliens havent visited us is for 3 reasons 1. They cannot get to us, most of these inhabitable planets are millions of lightyears away and it is impossible for an object to go lightspeed or faster without using an infinite amount of energy so it could simply be that they cannot reach us. 2. They simply have no need, id imagine they have inner politics and a currency system and itd be expensive to travel to another planet millions of lightyears away however if they did theres a big chance since there a millions of planets just like ours theyd have no need to, we would be labeled as not advanced enough to even be worth bothering. We havent even past out galaxy or solar system or even to mars, what good does it serve intelligent life to visit a planet with non-intelligent life when there are millions of others just like ours. 3. They arent advanced enough, the universe is only 14 billion years old and it took earth 4.5 billion years just to put a rover on mars not even a human so if we arent having much luck going to other planets most likely these other planets arent either and you have to take into account our brains grew rapidly in the span of 3 million years, like faster than any other species had ever grown, what if we’re the most intelligent life on the universe, what if every alien is just about on the same stage as us or maybe they just got past the solar system, its interesting to think about

Take this with a pinch of salt, as it's heavily my own interpretation from a massive amount of sci-fi and physics consumption and a nice dose of nihilsm, but here goes: The issue here is making it human-centric, as we humans are so prone to do. A better interpretation is not that you are "creating" a timeline, but simply fulfilling the conditions of a timeline that already existed. A parallel universe isn't necessarily running in sync with ours on an equivalent timeline, they already have their own timeline with preset events, just like ours. Due to the infinite interpretation of Multiple Worlds, it's inevitable that there will be a universe that's so alike to ours but behind in appearance, that you, as a human who has to interpret things in relation to themselves, would assume that it's your own past. But it's not. you haven't even time-traveled at all, just been moved to a different location in a different universe. You aren't changing anything, because it was already going to happen anyway. You're not on your "own" timeline, you're in a parallel universe that you were always going to reach. "You" don't have anything to do with it, it was always there, you were always going to go there, and do whatever it is that you do there. Seems like you were already there with the part about "think is yours and probably just isn't", so kudos, you're on the right track, but you need to apply it to the entire scenario in a less personal interpretation. As for returning, if you have the sensational technology that allows you to dimension hop in the first place, you'd hopefully be able to use it to hop right back. As you rightly surmised, it was never "your timeline", just *a* universe - a location that still exists, and would continue to exist, for you to return to. In fact, you already did or didn't return, and nothing will change that because your original universe already has a set timeline, too. You might even hop back in on a different point in time, but that already happened if so, and we've just never gotten word of it. Think Star Trek Prime Directive, but for time travel (which is also a thing they have). A sort of half-way thought to use is that a timeline is only relative to you, and what you experience. YOUR past is a fixed experience, but so is your present and your future. Everyone else is experiencing the exact same phenomenon. For you though, the future doesn't exist yet because you haven't experienced it. Same for them: if you tell someone that you have come from "the future", you haven't, because that future does not exist for them, what you have come from is YOUR past. Is this more confusing? Maybe, but it's the best way I can rationalize it to work with our self-oriented POV. Naturally, we can't work out all these things beyond theoretical speculation anyway, because our 3D human brains can't interpret time as an axis. TLDR: Maybe you could go into "the past", but if so, you've already done that, it wouldn't be *the* past, and nothing would change. Thanks for attending my TED talk.
