The Universe will end when it can no longer contain all of Simon's channels

Dear Simon, we absolutely adore space themes on sideprojects. The last few months have been full of them and its been a blast! Keep them coming, please

There is a theory which says if anyone ever figures out the universe it will instantly be replaced by something even more unfathomable. There is another theory that says this has already happened. - Douglas Adams, Hitchhikers Guide to the Universe

It’s also a popular theory that the supermassives were what is called a direct collapse black hole. Matter was so dense in the beginning that certain objects simply collapsed into black holes before even becoming stars.

The Great Attractor was discovered to likely be the Vela Supercluster, discovered in 2016 and of sufficient mass to explain the Great Attractor.

I love how the universe is a side project

[HBrooks]

in an infinite universe, with no beginning and no end, there's also no end to your kickass videos. informative and mind-expanding. thanks for the effort!

I love how SMBH sounds like it was named by a child ❤

[PRCOM]

Mention of the white hole reminded me of Red Dwarf 😂😂😂

Thanks Simon, for everything I didn't know, for everything i'm yet to learn. It's great to hear a presenter who is not over dramatic on these subjects. You do a great job.

Cool video this.. fascinating! The 2D into 3D just feels right for some reason! .. the joint I just smoked probably helped though..

[gregburns]

Thank you for putting time and effort into this. It boggles my mind and you help un-boggle it a bit.

ery impressed with this video. I have always been interested in astronomy and physics. It was things like this that drove me to enter those professions. Thank you for feeding my insatiable curiosity about the universe and the wonders that we discove

0:35 - Chapter 1 - Supermassive black holes may predate the big bang
3:25 - Chapter 2 - The great attractor
6:45 - Chapter 3 - White holes
9:40 - Chapter 4 - The holographic universe

my probably wrong theory on the 'great attractor' is it could possibly be a new class of SMBH, but galactic in scale. if it was as large as this, it would be harder for an accretion disc to form with enough density to give the usual radiation signatures we see on other black holes. maybe. i dont know

The most amazing explanation of the timeline of our planet I have ever seen.

[miltonable]

Simon Et Al will you please sort your sound levels out, I almost just blew my speakers out. Across your channels the levels are never the same. P.S. love your work ;)

[Enjoymentboy]

I like the idea that some of the supermassive black holes were actually formed from "shrapnel" from the big bang. That when the singularity "exploded" it did not do so evenly and some chunks were left that were still dense enough to remain as mini-singularities.

White Hole: one of my favorite Red Dwarf episodes!

Love these videos, reminds me about how much we don't know.
