El Gordo (The Fat One) Galaxy Cluster - Deep Sky Videos

[@VincentGroenewold]

I'm so thankful you make these videos, as well as the other channels. Thanks to everyone involved!

[@zzzaphod8507]

Great to see another video with Prof Gray I'm glad the importance of uncertainty in the estimates was mentioned!

[@jursamaj]

I think even more important than the uncertainty is the small sample size. On a sample of *1,* an oddity isn't that surprising.

A very heartwarming story about your friend Felipe, we all have our little academic families to thank

[@bazpearce9993]

Euclid will give us more info on this. Looking forward to the first science results. Please do more NGC videos Brady.

[@NomDayPloom]

We call our orange cat 'Gordo' because he is a chonk. Now, here we find out he isn't only a chonk, but a galaxy cluster influencing our models of the early Universe. Very good cat! 🐈

[@Olhado256]

Depending on how big his error bar is, he might be not just a chonk but an absolute unit!

Congratulations one of the best real informative astronomy channel. Nice audio, perfect explaination without useless emphasis, nice selection of subjects. 👏👏👏👏

[@redwater86]

Love this channel so much! Thanks!

[@trainwreck3697]

Cool video as usual. One very minor point, “flaca” means thin or skinny, not exactly flat, that would be “plano”. ☺️

Always a happy day when a new Professor Gray 60 symbols (edit: deep sky) Vid drops.

[@yeet1337]

not 60 symbols

Thank you!

I understand that a Galaxy Cluster are Galaxies gravitational bound together. But Gravitation is everywhere, so, how to discern Galaxies gravitational bound or not? Great Video, thanxalot.

[@garethdean6382]

The check is whether a galaxy is moving fast enough to not orbit the center of mass. If it's moving too fast it will 'escape' the cluster and so is not bound to it. This is actually a relatively simple measurement to make.

I'm always excited when there is a new Deep Sky Video, I'm only sad they are so infrequent.

[@faenethlorhalien]

They missed the opportunity to call it "Teh Heccin' Chonker" instead.

[@Veptis]

By "cooling" is that simply the expansion of space? as in atoms move away from each other and hence lower the energy per volume?

[@PaulPaulPaulson]

El gordo, like the spanish Christmas lottery

My favourite !!!!

[@KiloOscarZulu]

They don't have an Edge, but do they have a Bono?

[@FHBStudio]

What's funny is that this video would've been the same had the point been across the line with most of its error bar below it. It's within error so there'd be no definitive answer.

[@judychurley6623]

I would think that an error bar is symmetrical around the data point.

[@FHBStudio]

@@judychurley6623It is, usually (depending on the underlying distribution). Which is why I said/meant that had the actual point been on the other side of the line, the lower end of the error bar would not have been.

😥 she's old now

[@NorrisSaiyan]

She’s older, yes, but I don’t think all that old, she’s just running with the Gray hair, which is the noble thing to do

[@judychurley6623]

@@NorrisSaiyan So are we all to exactly the same extent, no error bar needed.

[@ZennExile]

Cling to the model, defend legacy over evidence. It's what Einstein would have wanted. (warning! this textbox contains sarcasm)

[@judychurley6623]

This study is evidence, with the error bar helping define the range of certainty/uncertainty. That they are looking and measuring to test the model is what is interesting. If the data point fell out of the range, they would have excepted that, and moved on to a new theory.
