Time Travel/Bootstrap Paradox?

[Neogaia777]

The light itself doesn't age.
From the light's perspective, it's at its origin and its destination at the same time, no matter how far it has traveled.

I don't know whether or not photons can age or not, etc?

But the images generated by light can be either younger or older though, depending on when they were emitted from/by it's source, and depending on where you are at on the receiving end of it from that source, etc.

 

[Neogaia777]

Yes.

K, now something very, very distant, if you could get there in an instant, would the time/age of that totals light distance, would it need to be accounted for so as to show what age/time everything really was there right now? Or would that all need to be taken into account, and/or accounted for? Maybe to prevent you entering a completely different "arrangement" of stuff/things things/stuff, etc, anyway, wouldn't that all need to be accounted for? And if so, then couldn't the whole entire universe be said to be the same equal "age", equally everywhere right now? Regardless of whatever we were seeing of it from our present position right now?

I'm afraid I have no idea what you're trying to say there.

Basically, yes. Note that this doesn't prevent time dilation effects, like the twin paradox.

 

[Neogaia777]

Basically, yes. Note that this doesn't prevent time dilation effects, like the twin paradox.

I'm not right now saying what needs to go there in that amount of time, or even how right now, etc.

But, you basically agree with me then, but there are some (many) on here who don't though, or don't seem to though, etc?

Or maybe some of them actually do maybe, but just are maybe (because of the nature of these forums sometimes maybe) are just always on the aggressive, or defensive maybe though?

Take Care.

 

[Neogaia777]

I'm afraid I have no idea what you're trying to say there.

If you had to adjust for billions of years of time of things being in a much different place now, then it might be a whole lot different than what we are right now seeing of it right now. Is basically what I was trying to say there I guess, etc. Or that's at least a much easier way of saying it anyway right now, etc.

 

[Yttrium]

I think there is just a problem understanding each other. Others here have been accurate with the science stuff.

 

[Neogaia777]

I think there is just a problem understanding each other.

I hope that's all it is.

Others here have been accurate with the science stuff.

I don't claim to have understood absolutely all of it with my current understanding/level of knowledge, but the attempts at understanding (and considering) one another (and their ideas) should work both ways though, etc.

I will continue in my growing and learning more however, etc. But will also continue to question every perception along the way, etc. Because that ability has gotten me where I right now am with pretty much everything, etc, and with many other things I right now know or understand, etc.

Take Care.

 

[Larniavc]

It's a very, very simple question?

You really mean to tell me you don't understand the question really?

Just answer it already please. A simple yes, or no, will suffice.

Because it really is that simple really.

I'll repeat it again:

"Are any light distances that we are viewing from our present position, are they also that "old" or not, as viewed from our present position or not?"

Yes or No will suffice.

You guys seem to handle all of this other "stuff" just fine, so are you now going to tell me you're having a problem with "this" now really?

I mean, come on now, really?

That sentence does not read very clearly. Are you asking how old far away things are?

 

[Larniavc]

I don't see how you guys can seem to handle all of this other stuff just fine, but can't even understand the most basic of questions seen by or observed through a "child's eye", etc?

The thing is, a ‘child’s’ eye is often overly simplistic and poorly defined.

Hence you’re question confusing people.

 

[Neogaia777]

That sentence does not read very clearly. Are you asking how old far away things are?

Or could be near, anything at any light distance away.

 

[Larniavc]

Or maybe some of them actually do maybe, but just are maybe (because of the nature of these forums sometimes maybe) are just always on the aggressive, or defensive maybe though?

That has to be it.

 

[Neogaia777]

Hence you’re question confusing people.

Then why does it (the question) seem so simple to me.

Anything at any light distance away, that it takes that long for the light to get to you, is it also that "old" or not also, etc?

Or if you could jump there in an instant, how would it appear when you got there?

If it were 5 light minutes away from you, would it be five light minutes ahead of what you were seeing of it when you left if you could get there instantly?

 

[Neogaia777]

That has to be it.

Well, then let's all of us (myself included) all agree to cut that out then, ok.

 

[Hans Blaster]

What's a "light distance"?

 

[Neogaia777]

What's a "light distance"?

Any distance where it is within our ability to measure or gauge, or be able to tell or know right now, the difference between what we are seeing of it right now, and what is actually happening or is actually present over there right now.

Would depend on the sensitivity of our instruments probably to be able to measure it or test it close right now, etc.

I'm sorry, but that doesn't make any sense.

Sensitivity is not an issue. Physics limits our observations of distant object to only the precise moment in the past corresponding to the time it take light to travel to us. If we want to know what happens to an object in its future relative to what we have just observed we have to wait. This is how we can observe the time variability of objects like AGNs and SNe in distant galaxies.

Light travels approximately 3 football fields in a microsecond, so if we could show that from either one of those positions/locations that they are also a microsecond old or in the past from either one of those locations when observing what is happening or going on in any of the other locations, etc...? Well, you figure it out from there, because I feel like I've already been about as plain as one can possibly be about it here actually, etc.

We could truly show that what we are really seeinig of it was/is truly in the past, and that we'd have adjust or account for that if we wanted to see it as it actually is now, from both theirs and ours, present locations, etc.

The principle applies for "local" things as well. We see the sun as it was 8 minutes ago and if we want to see what it is doing "now" we have to wait 8 minutes for that information to arrive. This applies for even shorter distances, but the processing time in the eyes and brain for images are much longer than any light travel time from a terrestrial object you can see.

Figure out what? The physics of information travel? I already know that. The question is about what you are claiming and the confused nature of your posts.

Edited my post a bit that you quoted.

We could record the two locations on different camera's or instruments and later on compare. There's a way to do it for those who are truly interested in it and/or truly care about it, etc.

 

[Neogaia777]

@Hans Blaster

Either way, however far away it is is how much were seeing it in the past, and to see it as it "now", you have to account for that, etc. And the universe is the same equal age, equally everywhere, etc.

Now if that's too confusing for you, or confuses you too much, then I am truly, truly sorry.
