It validated GR, it did not prove

[@ZeroOskul]

@ianstopher9111 Prove, probe, test, explore, experiment, examine, look into, delve through, demonstrate. Words mean things. Einstein being Einstein, who had his 1905 Annus Mirabilis, gave GR validity. Einstein didn't just appear on the scene with GR and stun the world, he'd done that a decade earlier with SR, the Energy/Mass Equivalence, Brownian Motion, and the Photoelectric Effect. GR was a highly anticipated followup.

[@mikejones-vd3fg]

It doesnt matter, our understanding of the universe is terrible, physics hasnt even accounted for free will as a force, the universe might be alive, that physics is also relative, we woudlnt know sitting here making assumption by just looking at stars. Anton himself showed us a study that had a different electromagnetic constant in a far off galaxy. That proves Einstien doesnt really understand the universe and every physicist before him who assumed physics is the same across the universe and made their theories with that assumption. Physics itself could have evolved overtime, if the universes is alive and moving about in giant space wed be too small to see any changes on our short time scale of existence and conclude laws and constants when there really could not be any fundamentally. Which makes any extrapolation of what happened in the beginning also invalid. You can show me a million studies that prove a theory right, i just need 1 to prove its wrong, and we pretty much have it. Science isnt a religion by the way, its a process of investigation, its not the conclusion, theres no followers of science, theres just doers. And the conclusions are up for scrutiny, always. Without scrutiny there is no science, its a religion with followers and fans cheering it on and persecuting those who dont. When i say it doesnt matter, i mean if physics is indeed different across the universe that would change everything, every theory would be wrong up to this point. And JWST is showing us more and more our understanding of light and age of the uinverse is wrong so it aligns with the fact we could have variable phsyics, if not across the unvierse, maybe over time. But that study Anton showed us we might have different physics not just due to time but space too. A galaxy could set the constants perhaps, and they could slightly vary. Amazing for the possiblities with exotic physics. The point is we need to get out there and explore to know for sure.

[@PreppenWolfLLC]

Gravity bending light directly disproves a lot of cosmology including distance and red shift. If light's velocity can be altered via gravity, then you cannot use the incoming light's shift to measure its original velocity. As you have no idea how far away the lensed object is from the gravity lense. We cannot solve this problem until we learn to measure the speed of light in one direction, which relativity prevents you from doing.

[@SomeoneCommenting]

When you think about it, the farther you see anything in time at the visible edge of the universe right after the big bang happened, nothing that you see is "where it is" since its light has traveled so much crossing the entire universe until reaching us that every single galaxy in its path bent the light a little, and a little, and a little, bouncing like a pinball machine ball as it continued forward.

[@stevenkarnisky411]

If enough gravitational lensing effects were piled up in a row, we might be able to see all the way back to the big bang! If one more lens were added, could we see to before the big bang? Thanks Anton!

[@Gregorythe5_5551st]

The thing is, the universe used to be too dense for light to go through for a few hundred thousand years, so you couldn't see before then, in fact this is why the cbm didn't immediately start at the big bang. And I'm not too sure about this but if I remember correctly time started existing with the big bang, so there wasn't any before to speak of.

[@stargazer5784]

​@@Gregorythe5_5551st I once heard of time being described as the measurement of a sequence of events. I suppose that under that strict definition, one might say that time 'began' with the big bang, but we can't know with any degree of certainty what may have been going on before, or if there was a before. Mind bending stuff to think about.

[@Deeken171]

This is just my own personal gut instinct based on the kind of information I've consumed over the years, but I have a feeling that actually perfect cross or ring shaped Einstein rings, are actually the outliers and in reality light is bent and twisted in so many random ways before it ever reaches us that we'd be hard pressed to ever really full understand it. It'd be like trying to follow and untangle a string that is bound together with millions of other strings for miles. For all we know, most of what we see in the night sky could be an illusion of the same objects repeated over and over in different phases of their life cycle. Especially the further away from our local galaxy you get.

Hello wonderful Anton this is person 🤣

[@VGAstudent]

If you look at the way the light bends and forms almost a small bounce when the light paths are looked at, is similar to the idea that the world was the center of the universe where planets were stars seen to fly in epicycles; what the light beam paths reveal is that the light actually orbited around a supermassive black hole before leaving to become lensed by the star, and the different areas where the light bent is where the lensing star was in it's orbit relative to the supermassive black hole in the same line of sight, forming something of a parallax?

So maybe the elusive Dark Matter Clumping, with its varying different densities, could also play some sort of part in these varying "distorted" gravitational lensing effects... other than just the orientation and the ever expanding distances via (Dark Energy) of a light emitting object/objects being projected around another objects background, into our observable foreground, here? Interesting... indeed. 🤔

[@crazyjkass]

Dark matter doesn't really clump, if it's particles they're not self-interacting except by gravity. Ie they're not colliding with each other the way massive particles like protons/neutrons/electrons/muons etc. more like photons. I used to be in the primordial black hole camp but when we looked for gravitational microlensing back in 2015 there just wasn't enough. I was confused and disappointed as I classified tons of images and my hypothesis was demolished.

[@Unknown17]

@@crazyjkass There's that, plus the minor detail that neither "dark matter" nor "dark energy" exist.

[@nmarbletoe8210]

@@crazyjkass cool that you worked on classifying images! interesting i guess we would say that DM doesn't clump but does gather?

[@wayneharrison]

​@@crazyjkass The "Dark Matter/Dark Energy labels" only relates to various observations of unseen forces via their interactions and influences on regular matter, as I understand it... correct me, if I'm wrong? However, if this is indeed is the case, real uniformity in nature tends not to be a thing, while on the "surface," patterns in nature are observed. It's only when you look deeper, you notice slight differences... the apples with apples comparison, as a scenario. Hence, my Dark Matter Clumping, that "might" explain Galaxy irregular formations... other than internal gases and star building processes from within, along with the occasional external collisions and gravitational influences (if they are present) from nearby neighboring Galaxies. Meaning, the greatest enemy for uniformity, is perturbations and time. i.e. Edward Lorenz: The Butterfly Effect/Chaos Theory. 🦋🌪

[@stargazer5784]

Spectrum analysis reveals whether an object is a lensed image or not.

[@crazyjkass]

Strong gravitational lenses, that is, lensing that you can clearly see are rare. Most lensing detected is microlensing. Microlensing is too subtle to be detected by the human eye and has to be sussed out with statistics.

[@davidh.4944]

Fewer galaxies would mean fewer lensing events. Also, lensings tend to distort objects, along with magnifying and duplicating them.

I have to point out that they will be answering question about the expansion as it was however many billion years ago, in that particular area. It is starting to look like expansion is not completely uniform, and it certainly appears to have accelerated over time.

They discovered the expansion is accelerating back in 1996 and got a Nobel Prize for it.

Mass bends spacetime, which is a shorthand for mass/gravity bends the path of all particles travelling through that area. Strong gravitational lenses like in the video are caused by massive galaxy clusters bending spacetime enough to be visible to the eye, like looking through a drinking glass.
