Study Tries To Solve Hubble Tension But Reveals Something Strange Instead

Hello and welcome! My name is Anton and in this video, we will talk about an attempt to solve the Hubble tension by observing Milky Way's motion through the cluster Laniakea

Last time i was this early, the Great Attractor was just the Moderately Charismatic Attractor.

[t.c.bramblett]

Thank you Anton, you are without doubt the best Cosmology and astronomy teacher on YouTube.

[luminouseclipse]

Thank you for all of your hard work with the videos every day! Love you bro!

[artcafe]

I have been watching your channel for a while and I want to thank you for the vast amount of information you put out and all the reports you provide. I honestly don't know how you have the time to put it all into such short videos.

Thank you!

[SilverAlex]

I love that everytime we try to solve the hubble tension, shit just get weirder xD

[glyngreen]

The Great Attractor was in Doctor Who I remember - it’s actually a gigantic artificial black hole shaped into a computer running an AI. It goes crazy and tries to destroy the universe and most of the advanced sentient races of the universe gang up and fight a time war to destroy it. Perhaps this explains the crisis in cosmology?

[jasonmcdowell]

It makes sense to me as the density varies across time-space. Locally gravity would have some drag on the expansion also.

[MCsCreations]

There's a study from a few years ago that claims that if you remove the corrections (from Milky Way's movements, basically) from the supernova database, the acceleration of the expansion disappears. In other words, you still have the expansion, but in a constant form.
I'm not saying that this is the correct solution, but at this point I think we should restart from zero and recalculate it. Without any bias and accepting any solutions.

[LevelofClarity]

Every time Anton publishes a video I am thankful.

TY Anton for showing us what's causing so much tension in Cosmology.

[charlesblithfield]

It must be so interesting working on this stuff with macro galactic distance, time and mass scales.

[petrosros]

I wrote about this in your comments section some years ago.
I in order to measure something you need first understand what it is, then construct an appropriate ruler. Standard candles are ludicrous, I remember thinking that in my Science class in the sixties, and have no reason to change my opinion.

[jimcurtis]

Wonderful as always Anton. Thank you. 😊

dark matter, the cosmic joke that's been baffling astronomers for a century, and there's still no sign of the punchline. It's like they've been on an intergalactic scavenger hunt for a hundred years, and all they've found is a trail of breadcrumbs leading to more confusion.

Picture this: Astronomers, with telescopes pointed at the void, scratching their heads over this riddle that's been going on longer than your grandma's prized pickle recipe. Suddenly, they cry out, "Dark matter is the answer!" as if shouting it loud enough will magically make it true. It's a bit like believing if you chant "Open sesame!" to a brick wall for long enough, it'll turn into a door.

They've essentially transformed the pursuit of knowledge into a century-long Monty Python skit, where the punchline is perpetually delayed. And they're the stars of this cosmic comedy, playing the role of the befuddled protagonists who never quite get the joke.

But wait, there's more! Not only is there zero direct proof after a hundred years of searching, but dark matter conveniently shapeshifts into whatever form astronomers need it to be - Mothra, Godzilla, or even the Loch Ness Monster. It's as if the universe itself has a sense of humor, and it's pranking astronomers on a cosmic scale.

So, here's to our tireless astronomers, who've made chasing invisible phantoms a century-long endeavor. It's like they're stuck in a never-ending loop of a cosmic sitcom, with dark matter as the recurring punchline that never quite lands. Keep the popcorn handy, folks; this comedy of cosmic errors shows no sign of a finale anytime soon.

There was an awkward smile at the end. 😮
This whole subject was new to me. So relaxing to sit back and let it all soak in and over think. Thank you!

[charlesjmouse]

An, a-hem, observation:
Having calculated the Hubble constant via the cosmic microwave background we have a 'universal average' that doesn't agree with our 'local measurement'. I know the analogy is far from perfect but as it seems we find ourselves living in an 'explosion' would it be any wonder to discover that it's not perfectly homogeneous? No 'special physics' required, just an understanding that explosions tend to be 'lumpy'... So let's go measure the Hubble constant in other places if we can and see.

[stevenkarnisky]

Thank you, Anton! It is still very early in our quest to understand the universe around us. Our tools are still rudimentary, and even our mathematics is sometimes suspect. The only way to achieve accuracy is to keep at it.

[RED]

There seems to be a basic assumption - the universe is expanding at the same rate.
Why is that assumption true?
Could there be different rates of expansion depending on angles and mass? How about obstructions on the way (black mass)?

[docholiday]

The problem is labeling.
"Hubble Constant" should be "Hubble Variable".
String theory hold the answer.

[stuartmaclean]

LOL, "It makes the cosmological mystery even more mysterious, or even more unsolvable than before. And the biggest question of course is do we have any solutions to this?" Yes I have plotted a solution. I do love to answer big questions like "Why is the universe homogenous and isotropic?". Thank you, thank you again, more evidence to put into my pile.
