What if our observable universe is just a bunch of light particles that came out of a solar storm/burst of a gigantic star??? The bursted particles moves away from each other at the speed of light and the rest of the objects are in non observable universe and are the so called early universes(that jwst exposed) and we somehow called this entire event as big bang...

My answer to the photon question: At relativistic speed, space contraction is a thing as well as time dilation. Wavelength is a function of distance and time. Since the photon experiences no time, the space contraction is infinite. It doesn't see itself as being redshifted, it just "is". The perceived redshift is due to the mechanics of our observation, not of the intrinsic properties of the photon. The photon itself has the same properties at detection that it had at emission, but our relative time and space reckoning is what gives the illusion of redshift.

You can change the perceived red shift of the photon by changing your reference frame. For example, if you move closer to a black hole, you’ll see the photon red shifted. This means the redshift of the photon is a consequence of your observation of the photon, not a change in the inherent properties of the photon.

But isn't the very nature of redshift something that can't happen to a single photon? Redshift is an increase in wavelength, ie: a longer period between photons. IOW, it's a decrease in the frequency of the light. The single photon doesn't have a _frequency_ though: it only happens once. So the photon (particle) doesn't experience redshift, the _waveform_ experiences redshift.
@victorrielly4588
@victorrielly4588 4 ай бұрын
@@billmcdonough3950 the same photon will have a be perceived to have a different redshift depending on how fast you’re moving with respect to the photon. Just like there’s only one electron in the universe (they’re all identical to each other) there’s only one photon in the universe (They’re all identical to each other). One way to see this is to remember that the wavelength of a photon is inversely proportional to its momentum, and the relative momentum of a photon is dependent on the momentum of an observer. If the observer is flying toward the source of the photon really quickly he will perceive the momentum of the photon traveling toward him to be very high and thus the wavelength very small (blue shifted), but if the observer is flying very quickly away from the source of the photon he will observe the photon to have a much smaller momentum and to be redshifted.

So by the time those photons are observed on the earth, the wavelength has increased.

From the photon's perspective, nothing changed and no time passed. We simply experience the photon differently than the people who emitted it... we and they can do this because neither are traveling at c and time does pass for us. Each peak and trough of the photon's wave is frozen in time, but both the emitter and detector see each peak and trough at different times -- and the relative motion/gravitation between us shifts those peaks/troughs closer together or further apart.

I'm late to the party but since you are at the center of your observable universe it would mean that you are at the singularity of a black hole. And so basically any point in space would be a singularity since it is at the center of its own 93 billion light-years sphere of observable universe. So either the observable universe is not a black hole and it's just a fun fact that its "barrier" and the event horizon behave the same, or black holes don't have any singularity at their center. I'm leaning towards the former since there are other facts about black holes that doesn't fit my observation of the universe (matter distribution, tidal forces, etc)

About the question regarding photons and red shifting: If something acting upon the photon potentially causes it to experience time, could the same not be said of gravity causing its path to curve? The photon would experience stretching instead of steering as it travels through the expanding universe, so I would think they are similar in that regard. I would imagine as long as the photon is not stopped/observed, it doesn't register what the outside forces acting upon it actually do, with regards to the time aspect.
@HaggenKennedy
@HaggenKennedy 4 ай бұрын
I agree with you. I think it has more to do with frame of reference than with what the photon itself feels. You noticing a red shift is a consequence of your observation, not a change in the inherent properties of the photon. It's possible that it (the photon) may not notice that anything different is happening.

neil mentioning that the horizon of the observable universe is identical to event horizons got me thinking about how we all have our own individual horizons, and wondering if that also means that "we" aka our atoms(&quarks) are all made of "singularities" at the center of our own universes? and if so, is every photon, Lighting every singular Event we Observe, simply falling At us, at the speed of light, aka the terminal velocity of photons "Falling" into Our black hole universe?

I’m not a great communicator like Neil, but I find it’s actually (to me, at least) very simple if you think abuit it logically. Due to the speed of light, and the expansion of the universe, we can never send a signal that will even reach, much less cross, the edge of the observable universe, the same way that, inside of a black hole, you can never send a signal that would reach or cross the event horizon, or that you can never actually observe a signal enter a black hole is you’re outside of it. Additionally, as we look toward that event horizon, what we see is, essentially, the entire history of the universe, the same way you would as if you were falling into a black hole you would see the entire future of your universe. Mathematically, everything checks out, but, where we usually think of the math from the perspective of being outside the black hole, we have to take the inverse numbers because we are inside it, like being on the other side of an asymptote on a graph, which is what the graph of a black hole’s mathematics actually looks like as you approach the event horizon.

I see a logical contradiction in this analogy: We are, by definition, in the center of the observable universe. Someone, at half the distance to the edge of our observable universe, would also be in the center of their observable universe. Inside of a black hole, I think, everybody will agree on one, and only one edge and one center.

Is it? Once you are "inside", the event horizon is forever unreachable. At the same time, time dilation dictates that time would slow infinitely as you approach the singularity such that (from your perspective) it would take infinite time to reach it. This is not unlike our own universe.

Inside a black hole, the core, known as the singularity, is where gravity is so intense that it bends space and time to an extreme degree, leading to infinite density. Surrounding this is the event horizon, the boundary beyond which nothing can escape. Given these extreme conditions, how can scientists even begin to study what happens at or beyond the event horizon?

There's a bit of a circular case here. Indeed, to your point, nobody can ever do empirical science inside a black hole and get that information out to people on the outside. Instead, we do empirical science on the observable universe and model how it works mathematically, both general Relativity and quantum mechanics. Then we can see what the mathematical models predict happens inside the black hole. This is more or less what Neil says @14:10. It is a best guess based on the best evidence, but the accuracy is limited by how good the mathematical models are. On the one hand, we might argue that we can't ever know how accurate it is since we can't ever test inside a black hole and get the info out. On the other hand, our prediction of the existence of black holes, which we have confirmed empirically, and that you can't get the information out comes from those mathematical models. If those models are inaccurate about what goes on inside a black hole then they can also be innacruate about the ability to get information out. If we accept that you can't get information out from the models, why would we not accept the other conclusions of the same models. We a can't empirically prove that you can't get information out because if True we can't get the empirical proof out. At this point it is Occam's Razor. If we can't get info out, all we can do is model and the accuracy is irrelevant because what goes on inside can't affect us outside. If we can get info out, then we can improve the models, so we keep collecting evidence to find out where the models break down.

I think it happens because of the expansion of the universe artificially moving us away by creating space(very likely wrong that one)? Or expanding the light itself basicly redshifting it either way as time passes. Btw black holes can blueshift light if it travels toward the direction its spinning by the same principle basicly doing opposite of what expansion of universe does.

My hypothesis is that all mass taken in throughout the black holes existence "arrives" past the singularity all at once as time "kicks off" again past the event horizon. Essentially a "big bang". And when a black hole decays away via hawking radiation that's equivalent to heat death from the outside.
