super novae are only decreasing in frequency also, so the further back you look (until you get to periods before super novae were possible) the more likely it is you see one.

Does gravitational lensing of light and time occur at a 1:1 ratio?
Hopefound t1_jb8snne wrote
I would imagine that the answer is yes since light is just a phenomena that traverses space and time. Light can’t be impacted separate from the space time it travels through as I understand it.
Also, I could be super wrong and have no idea what I’m talking about, math is hard and I am dumb.
ImJKP t1_jb9ebvm wrote
Light travels at a constant velocity in a straight line through space. Gravitational lensing is an artifact of the kinks in spacetime created by massive objects; those kinks change what a "straight line" is for the light passing through that area of spacetime.
Time isn't affected by gravitational lensing per se. Gravity warps spacetime, and light is distorted (lensed) by the warped spacetime.

I'm confused. Wasn't Webbs' first picture taken last year? How are they 1000 days from the first pic?
RevengencerAlf t1_jbak72r wrote
It's all one picture. Due to gravitational lensing light emitted 1000 days apart in time reached the telescope at the same time. Basically the light from the first picture took 1000 days longer to reach us because the fabric of spacetime was curved forcing it to take a longer path while light emitted 1000 days later missed that gravity source so it was able to take the short route and get here at basically the same time.

Bob_Sconce t1_jbb313v wrote
So, here's the question: In the big-bang, everything ejected from this one point and spread throughout the cosmos. We are, at this moment, some distance from where that occurred at a location I'll call "X." This photo claims to show light emitted not long after the big bang. It's not possible to travel faster than light.
Q:. How did we get to X faster than the light?
bimundial t1_jbbqoiz wrote
There is no X. Things didn't get ejected, everything was extremely close to everything else, and of a sudden they started to get far away from everything else. It's like the surface of a baloon, if you inflate it, everything is further apart, there is no "point of ejection" on the surface.
Bob_Sconce t1_jbbs5br wrote
That doesn't really help -- if everything was extremely close to everything else, then just pick 'X' to be the geographic center of all of that -- the exact center of the uninflated balloon if you like. At the beginning, we may not have been precisely at X, but we were very very close to it.
(Also, I intended X to be where we are now, not where the mass that is currently the earth was at the point of the big bang. But, that was not at all clear, so I'm just going with 'X= point of the big bang.')
bimundial t1_jbbwvbm wrote
A ballon's surface doesn't have a center. If you inflate it, its area will grow at the same rate everywhere. You can put a point in any place of a sphere's surface and none of them will be the center, that's how it goes with the universe too, as far as I know.
So the big bang is basically that, it was a smaller area, maybe infinitesimaly smaller area, that just got bigger everywhere. Everything was just farther apart. There was no center before, there isn't one now, just like a inflated sphere surface.
Bob_Sconce t1_jbcds33 wrote
? The surface doesn't have a center, but the balloon does. If all the mass was on the balloon surface, then there is a point inside the balloon that is, effectively, the center of mass of all that mass. That's X. And, presumably, not ALL of the mass expanded outward, otherwise there would be a massive empty space in the middle of the universe. (As far as I know, that hasn't been discovered.)
bimundial t1_jbchal1 wrote
But the universe IS the surface. In this example, there is no inside. For an object placed upon the baloon, all that he sees is everything getting further apart, and that's how the universe behaves.
The universe was smaller, than it got bigger. It got bigger everywhere, in all directions, at the same rate. There is no 'X' direction where things got pushed out of, everything just got more distant from everything else.
Bob_Sconce t1_jbd1wp7 wrote
So, things got more distant from each other at a rate that was faster than the speed of light?
twistier t1_jbd3w5k wrote
The expansion of space does not have the speed limit that traveling through space has.
bimundial t1_jbdvkmc wrote
Yep. That's because the things weren't getting distant inside space-time, but space-time itself was expanding between things. Relativity only puts a cap on the speed things move inside time-space, not the rate that time-space itself grows
gyrofx t1_jbbev9q wrote
The way I understand it, there is no X, or put another way everything in the universe is point X.

I find this concept interesting:
If I die and everything just goes black forever, as is purposed by atheism, then I was THE ONLY real being in the universe. If I'm the only thing keeping the lights on, then I'm actually uniquely special. Because reality ceases to exist - all other life forms are not co-equal 'viewing windows' of the universe. If my individual view of the universe stops when I die, then there really isn't anybody else out there. You're all just constructs of my brain.
It seems odd to think that everything stops when I stop. I don't think that's how it goes, though.
VictosVertex t1_jb8tuw9 wrote
Your argumentation isn't logically sound because you're missing one very important part: it "goes black" for YOU. If you died now absolutely nothing would stop for me, so your basic assumption that everything stops is already wrong.
If your argumentation was true, then this would also be true for any device with any form of sensory input.
A laptop being shut down and never turned on again also makes "everything go black" from the perspective of the laptop itself. Does that now mean that the laptop in question was the only true being in the universe? Obviously it doesn't.
And you as a human aren't special in any way shape or form either. Your singular experience ceases to exist, nothing less, nothing more. Same goes for any experiencing being that ever existed.
Everything "went black" for every single person that came and went before you.
Also it doesn't really go black. It goes nothing. Your experience is gone, thus you couldn't experience black either. Everything, including the perception of time, stops for you, thus nothing ever can happen - from your no longer existing perspective.
Now to make it interesting again: Your basic idea of being the only true being may still be true.
Scientifically speaking there is no way to prove or disprove that you aren't hallucinating everything, including me. Even if I lay out the perfect reasoning of why I exist to you, you could've just as well imagined it. From my perspective this obviously means that I may very well just explain to a hallucination of mine how I could be a hallucination of it.
This goes for every single statement that is outside of science though. God may exist, you may be a Boltzmann Brain imagining reality, this may be a simulation, this may be a single version of a multiverse like a decision tree - all these "fun to imagine" scenarios are outside the realm of science. Thus they may very well be true (or false), but we will never know.
Which is also why science never states absolute certainty and only models what agrees with observation.
BoringEntropist t1_jb93bgt wrote
Atheism doesn't propose such a thing. It's just the philosophical standpoint that denies the existence of deities. That's all. Topics such as afterlife, souls and other metaphysical stuff is outside of its scope. There are schools of Buddhism that deny the existence of god but believe in reincarnations.
Atheism isn't a believe system. Same as "not stamp collecting" isn't hobby. Not believing in god doesn't mean a person can't believe in other supernatural stuff (UFOs, chakras, whatever).
BTW, the view that you describe about reality not existing outside of your own mind is called solipsism. That position stands on epistemological shaky grounds though.
[deleted] t1_jb8o1xl wrote
Sorry but this is pretty nonsensical. First of all it shouldn't be this very far-fetched concept after we die according to atheism. We already have not existed for billions of years before we were born. It's just a matter of returning to the state of non existence we were in previously.
So if that whole concept of death is true then you were the only real being in the universe? I can kind of see what you're trying to convey but those are a poor choice of words. I think a better choice of words is that you're simply literally the main character. Which lots of people have already made that point before. There's a good Joe Rogan motivation clip that makes that point. But just because each person is the main character of their lives doesn't mean that everybody else isn't real.
But yeah it's kind of obvious that everybody should be the most important person for themselves. The typical exception is parent's love for their children. I will give you an interesting example of a thought i had that lines up with all of this quite perfectly. Back when i lived in Israel when i was younger i gave myself this thought experiment if i had to sacrifice myself to save the entire country of Israel and the answer i gave was that i wouldn't. It's because military is mandatory over there and that's why i was thinking about it. Because i so didn't care about protecting Israel i managed to get out of serving in the military though that's no easy feat. (had to convince them i was seriously suicidal)

There's a scientific theory that there's only one electron in the universe, that every one is the same one just looping back and forth in time (the instances of it going backward are all the positrons). It's almost certainly not true (one flaw is that there are a lot more electrons than positrons, for example), but the thought helped lead to idea that particle/antiparticle pairs are the same, just reversed in time.

Emotional-Courage-26 t1_jbgp0fr wrote
Have you read about panpsychism? It is somewhat aligned with this idea. Rather than say you were someone else in another life, you could also say they were you in this life. We're all the same consciousness in all of the lives, perhaps all at once as you mentioned. We're the expression of the same fundamental force of consciousness.
Akin to saying we are all drops of water in the waves of the ocean, and at one time we were shaped as another drop of water that you know of. This is irrelevant to say because we are all part of the same body of water, and as such, are the same. We are more like features which emerge from it occasionally in various forms, constantly changing was we splash and ripple, eventually sinking back into the ocean we came from.
This isn't strictly what panpsychism is or what it means; there are plenty of hypotheses around what consciousness being a ubiquitous feature of the universe would really mean, with that being just one interpretation.
I really like to think about it. I'm not a panpsychist, but I'm not opposed to the possibilities either. I am a big fan of the idea that we're all made from the same stuff, with the same core "being", perhaps expressed differently through how our physical bodies develop. I can't be upset with people as much if I imagine their circumstance is largely a product of how their physical development played out, and more or less, they are me. Fundamentally they're exactly what I am, expressed slightly differently by forces they largely have no control over.
It's also neat to consider consciousness as a force of the universe, similar to gravity. Why does gravity exist, and what's it for? Well, maybe nothing. Same with consciousness. It's simply there. It's part of how the universe works.
Maybe we're within the atoms of a larger being, and we're conduits of its own consciousness. Like electricity flowing through a circuit to a co-processor. We're the tiny neural network within it, computing all these simulations to help it understand itself better.

doubletaxed88 t1_jb6s8sh wrote
No, it is one image. The objects are behind another supermassive object which causes gravitational lensing, and you see it three times. Because of the extra distance it has to travel as the light bends, you are seeing the objects in different moments in time.
Edit: I forgot to mention there is also something called time dilation with gravity, and the more you have it the slower time travels, so the images that are lensed with the most gravity arrive later in time.
Chichachachi t1_jb72447 wrote
But why is it saying one was 320 days later and the other is 1000 days later? If it is just one image, how would we be able to know the time dilation to the precision of days of time difference? But also, James Webb was placed at the Lagrange point less than a year ago, so I guess we DO know the difference that light travelled to the degree of days.
The supernova event is 3.2 billion light years away. But we can actually tell that one lens delayed the light from one image by 320 days and the other by 1000 days. Incredible.

It's one image, with the Supernova's galaxy appearing in it 3 times, at 3 different moments in time. The duration was estimated using scans from Hubble last year. Believing it to be a type Ia supernova (which all have the same luminosity) allowed them to plug the numbers and figure out the precise "prescription" of the lens that galaxy in the foreground is creating. JWST confirmed it's a type Ia supernova, which means their numbers are accurate.
Lensing is pretty well understood and they have amazing software to help them out.

How much of the night sky is lensed? Is there any estimates of how much you see is duplicates, or is it a rare occurance?

I think for that to really come into play, you need to be looking pretty far. Like it's not something you'll really see in the stars you see at night with your eyes in our local galaxy.
But sure, looking into deep intergalactic space, which requires a decent telescope, it's probably not all that uncommon. Take a look at some of Webbs early pics, you'll see lots of warped and stretched images which I believe are examples of that phenomenon as well. And those are just in small patches of space.

Bensemus t1_jbfjhei wrote
Yes. However we can't look all the way back to the Big Bang. The farthest back in time we can look with light is the Cosmic Microwave Background radiation or the CMB. After the Big Bang the universe was too hot for atoms to form. Electrons had too much energy. This plasma was opaque to light. Any light that was emitted was quickly reabsorbed and then reemitted. About 370,000 years after the Big Bang the universe kinda instantly everywhere cooled down to a temperature where atoms could form and suddenly light was able to travel arbitrarily far. This light is the CMB. This is a major piece of evidence supporting the Big Bang. No matter where you look you will see the CMB. It covers the entire universe.
To see past the CMB we will need to use something other than light. Scientists are hoping it will be possible to use gravitational waves or neutrinos to detect their equivalent of the CMB but both of those would have originated from the Big Bang or right after it as neither are blocked by plasma.

Just to be clear this isn't a time lapse. It's a single photos that has capture the galaxy at three different points in time. This is possible due to gravitational lensing. Light from the galaxy took three paths to get to us, each one longer than the last.

Yeah, and its a long enough time that you can't build an animation out of it, unlike this:

What's weird to me is that in an infinite universe where anything could happen there's no reason why dinosaurs could have lived without going extinct or even a different type of animal evolving with intelligence completely different to humans. Aliens to us.

I had a shower thought the other day that if an object in space were to travel through a “worm hole” ending up closer to an observer, the observer would then be able to view the same object, at some time, for the difference in time/space traveled. I wonder if this might be it, but I didn’t read the article lol.

There is no evidence of worm holes. Maybe in quantum computers but not out in space.
If you read the article it would actually explain what happened.

For those curious but don't want to read,
First picture: day 0 (3.2 billion light years from earth)
Second picture: 320 days from the first pic.
Third picture: 1000 days from the first pic.
How do they know this? A supernovae clearly seen from the first pic can be seen in the other two images with the same positions but fading away in brightness.
Why are they different timelines? Gravitational lensing that not only bends light but also space time.
