Hello wonderful person!

What I have learned from this channel is that reality is _somewhat unusual._

[blazeAkriti]

the first author of this paper is my friend, Fred (we are astronomers based in Chile). He is an amazing guy and scientist. Thanks for the great explanation

[coreysue]

Seeing the same object at different times of its life IS GOLD!

[chrisofthecosmos]

Long time viewer here. Got say Anton your videos are great. Keep up the great work man.

[GameraSoup]

I felt the same way, Anton. How can this even happen? The Golden Age of Astrophysics just keeps giving.

[StephenMcDonnell-hy]

All the videos are class but this is the business altogether. Cheers Anton

[Demonic_Tang]

I'm glad to be alive for such amazong discoveries. It may not seem like it, but we're living in a golden age of astronomy

[TJ-Network]

A new take on; Objects in mirror are closer than they appear. Thank you professor for your channel and explainations.

You know when the James Webb says, "Hold my beer..."
I think coffee came out my nostrils and tear ducts. Funniest astronometric joke ever!!@

🎯 Key points for quick navigation:

00:00 *🌌 Introduction to Einstein's Zigzag*
- Introduction of the discovery of "Einstein's zigzag, " a unique variation of gravitational lensing patterns.
- Explanation of gravitational lensing as bending of light due to massive objects between the source and observer, first theorized by Einstein.
- Historical reference to the 1919 Addington experiment proving Einstein's theory of general relativity.
02:02 *🔭 Importance of Gravitational Lenses*
- Gravitational lenses help measure the universe's expansion by observing light arriving from the same object at varying times and redshifts.
- Observations from Hubble and James Webb telescopes have revealed extraordinary lenses, with James Webb recently discovering the farthest gravitationally lensed object (21 billion light-years away).
- Hubble’s discovery of the carousel lens highlighted multiple galaxies at variable redshifts, revealing insights into distant cosmic structures.
03:50 *⭐ Discovery of Einstein's Zigzag*
- Description of Einstein's Zigzag, initially identified as an Einstein cross in 2018, with four bright points and two dimmer points.
- Reanalysis revealed it to be six copies of the same quasar, doubly lensed by two massive objects at different distances.
- Unusual lensing pattern caused by light passing through two deflection points, creating a zigzag formation and unique redshifts.
06:12 *🧐 Implications for Cosmology*
- The rare lensing phenomenon provides insights into dark matter distribution by analyzing light bending around the lensing objects.
- Time delays between the six quasar images offer a method to measure the universe's expansion rate, contributing to resolving the Hubble tension and dark energy mysteries.
- Comparing observed lensing effects with theoretical models allows scientists to refine cosmological parameters and understand mass distribution.
07:47 *🌠 Fascination with Cosmic Phenomena*
- Discussion of the strange and unexpected behaviors of light due to massive gravitational lenses.
- Mention of how objects in the universe may appear vastly different because of lensing effects, revealing the bizarre and complex nature of the cosmos.
- Tease for potential future findings and studies to build on this groundbreaking discovery.

0:59 Einstein/Eddington Eclipse Experiment, 1919
This proved General Relativity.
_EEEE 1919_
Don't forget it!
It matters!

The clarity of Anton's videos to those within and outside a given field is the standard I aspire to for my own presentations. Sometimes nuance is lost but his videos are the perfect introduction to research and I can decide for myself whether or not I want to read the papers to get that nuance back. Anton's format is basically a better abstract

[S.Kowalchuk]

You know the nearer your destination the more you’re zig zagging away.

[jeanpaulniko]

Thank you for distilling all this knowledge for us

[MrDermotMcDonnell]

Awesome, greatly appreciated Anton 👍

[lashamartashvili]

First ever Einstein's zigzag was discovered when Einstein got drunk for the first time.

[Haybott]

Thank you so much for your videos, Anton! Space has always fascinated me; I truly appreciate how well you explain your topics. 😊

Several students in my English class love discussing astronomy, and it's fun to discuss your topics with them.
Cheers, and many thanks! 😊

[jimcurtis]

Wonderful as always Anton. Thank you. 🤘😁🫡

Anton, God bless you for your hard work in giving so much quality information in a wonderful way. Rob
