The Andromeda Paradox - When is "Now"?

Is every "now" the same? Does the past, present, and future all equally exist? Am I having a crisis?

*Thanks for watching my past in your present, nerdling swarm*

[@AruthaSilverthorn]

Many thanks for your videos I always have questions like these in the back of my mind since take minor in Physics I still think there is an intrinsic assumption in physics that is causing a lot of these paradoxes: Physics is the Science of Measurement, and we measure with light hence light speed is fixed and we have paradoxes about measuring differently. The example of Schroeder’s Cat is even in the same ballpark of What is now if I can’t measure it...

[@christineapplegate4873]

So if astronomers took photos at different points of our orbit when we would be moving fastest and slowest relative to our collision with Andromeda, how different should we expect those photos to be and do we have evidence of the differences?

Prepositions of time for time travelers must will been “fun” ⏳🧠😎

[@FosukeLordOfError]

The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be descibed differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is futher complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father. Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later aditions of the book all pages beyond this point have been left blank to save on printing costs. The Hitchhiker's Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term "Future Perfect" has been abandoned since it was discovered not to be.

[@Astronomator]

This is one of the best, most understandable explanations of simultaneity I've ever seen. Thanks for this. Perhaps in the future, you could address what this says about whether our universe is absolutely deterministic. Also, your Carl Sagan is very good, I must say. Well done, all around.

[@ZeusHelios]

Shh! I don't want determinism, lets stick with free will. Determinism is scary. ☺ OK let's put up a fight I mean a debate. If there are infinite choices then I would think that therefore there's free will, even if there is only a finite number of choices then free will can still exist because you can infinitely choose any one of the finite choices avaliable to you even if you knew the outcome. It's a bit like determinism with free will thrown in. ☺ Sorry if I wasn't too clear.

[@Astronomator]

@@ZeusHelios No, I think you're spot on. Viewed from the outside, our universe is like a two-by-four piece of lumber (with four dimensions), with time being one of its dimensions. It is what it is (heh), and no amount of turning it in our hands and viewing it at different angles will change anything about it along any dimension, including time. The future is as immutable as the past, and everything is 100% deterministic. That the future is as unchangeable as the past and that our universe is 100% deterministic is the logical conclusion we can draw from the way the universe jumps through whatever hoops are necessary to make simultaneity what it is, since one person's future can be another's past (and vice-versa), and both perspectives are perfectly valid. I know some won't accept that one person's future can be another's past and vice-versa, but we see this in other phenomena. Think of two trumpet players playing the same tune. One is standing on the sidewalk, and the other is in the bed of a pickup truck zooming away at 30mph. Due to the Doppler effect, each will swear the other is flat, and both perspectives will be valid. So if the universe is an immutable loaf, there is no free will. However, all our experience tells us that free will exists since we perceive time only in the present moment. All our experience tells us that we CAN change the future, but not the past. We can debate whether the flow (arrow) of time is an illusion and that we're just unchanging chrono-smears in a piece of lumber. But I believe (with admittedly no evidence whatsoever) that our perception of time is valid, and that we live only in the present moment and perceive the arrow of time as a feature of the universe. So does free will exist? From inside the universe, yes, it does. From outside the universe, no, it doesn't. And as with the trumpet players, and as with the two beings in different galaxies experiencing each other's future and past, both perspectives are perfectly valid.

[@ZeusHelios]

@@Astronomator ☺ 👍. What about consiouness? Does consiouness of our past still exist in our past even though we've traveled forward in time into the future. For example a 10 year old. Would a 10 yrd old still be consious of existing as a 10 Yr old even though that person is say 30 Yrs old now? In other words are our past still there and still self consious of itself existing in that time frame even though its in the past. Also say an consious alien exist on another world 100 light yrs away, we look at each others world from our own worlds seeing each others world as it was a 100 yrs ago. Let's say both human and alien died at 90 earth yrs would they still be consious or does light only carry physical images or does consiouness go with it. I suppose just as a video carries images the images probably don't carry with it consiouness. Silly questions I know probably because of my ignorance of how time works.

[@ZeusHelios]

@@Astronomator If the universe and our life's are predetermined then all the more we should do everything we can to make our lifes a happy predetermined life. ☺ We should be doing that anyway but some how thinking of a predetermined life is scary to me so all the more I feel I want to put more effort into making sure its a happy predetermined life. ☺

[@Astronomator]

@@ZeusHelios Ah, now you're getting into emergent qualities of the universe: things like consciousness, love, and the creepiness of scorpion mouth parts. I'm no expert in such things, but I would certainly say that if two beings can be living in each others' past/future, then by extension every moment in time (spacetime, actually) is always a valid perspective. Thus, you are always you, in whatever slice of your chrono-smear you choose to examine. So if consciousness is a thing (and I'm not saying it isn't, it's just that I can't prove it), then the ten-year-old is/will-be/always-has-been conscious of his existence twenty years ago.

Both of these post have entered the past and symbolize a societal interaction through the space time continuum roughly 1 hour apart. Perhaps these are not the only 2 post in the chain right now?

What two observers see at the same point in spacetime is completely defined by photons hitting their retina. At the same point in spacetime those are the same photons, so those observers see the same thing. Regardless of their relative speed.

[@2QRh6g1I]

Perhaps only quantum-entangled particles can truly share the same "now"

[@TESBADWOLF]

Consider you're observation of "now" as a ping in space: the sooner the response -the more relevant to the present, as the ping travels further in space, it travels further in time and becomes less relevant to the present. In order to truly capture a moment in time (to an approximate relevance) you would have to simultaneously collect data from multiple points at once (likely quantum tech), save it, send it, and compile it. From there you would have data account for what's happening in all of those spaces at that given moment. Basis is similar to looking at a mirror in space that is 1 lightyear away. You'll see 2 years in the past. Taking photos of things that are lightyears away results in data that is years old. If you wanna know what their "now" you would need to either be there or perhaps use quantum entanglement tech. Assuming its "entanglement" truly surpasses the speed of light to that degree

[@benpearse7565]

Yeah we'd need instant data transfer over large distances to actually measure this. Cool concept though.

[@TheBorkers]

The speed of light is also the maximum speed of causality. Nothing can effect anything else faster than light and that includes the transmission of information. Discernible information cannot be sent via entanglement. Even though observation of one particle would cause the wave function of the other to collapse in a perfectly predictable manner, the outcomes would have to be compared to transmit information. How would the two parties observing both entangled particles be able to compare results and communicate their comparison faster than light? That’s the problem

Well then, when will then be now? But then again, when then is now, what is now if not just then. When you think of it, if then would be now, then now would also be then, which then brings us back to the now-then dilemma.

[@kittaunne4074]

Another great video, thanks for putting these in more simplified examples!

[@gavsmith1980]

Sometimes it’s easier to look at it the opposite way, there is no “now,” it’s just the latest ripple in space, time, matter and energy from the Big Bang, where as soon as you’ve consciously observed it, it’s already in a slightly newer state.

The way I see it is that the paradox comes from the fact that no matter how we percieve things they still happen "now". It does not matter what the two nerds see because none of them are seeing it now. So we are just not capable of determining when now is if it is far away.

It's the new Penrose Paradox - his surname is legendary but his first name isn't.
