Well that unexpected excellent.

This video is informative but so strangely "ugly" somehow, like it looks like 1997 Stargate SGI cg or something, I can't put my finger on it. Was this all created by one person or a whole company?

He has a video on his channel where he explains that he’s making these videos alone after having started to learn Blender a few years ago. And that’s why he has so few videos.

I definitely see what you mean: it’d look bad from a big production, but it looks unbelievable to me from one person. I can’t quite comprehend it really.

Solvency3• 2 years ago

Eh. This magnum opus of an animation was created by one lone 3D artist in 2009!!! and it's not only a work of utter art, it looks better than 99% of videos on YT today.

I think YouTubers are conditioned to think it's impossible for one person to execute anything impressive because they're otherwise drowning in a sea of shit tier videos.

Obviously this is subjective, I just wanted to say that I personally found it's production to be incredibly beautiful.

The video seems to fall ever so slightly within the uncanny valley. The quality of renders and animation, especially the motion capture and facial animations, is far beyond anything I’ve come to expect from individual creators.

But it does seem to have landed just within the far edge of the uncanny valley. Often good enough that you don’t really notice, but occasional moments where it feels very odd and distracting.

It does also look like he’s had to make some compromises on render quality. There’s render noise appearing and disappearing at times, which is usually an indication that not enough rays were used during ray tracing, resulting in some pixels have very odd colour values. I can only assume that just the result to having to trade off between render time and render quality, especially as it seems he’s putting in quite a lot of effort to make sure the render and simulations are physically accurate. A very computational expensive thing to do, especially when trying to render crazyness like black holes that warp and distort space time.

Probably the weird orange/desert hue

Theres no way this is a single guy working in this channel

sakopov• 2 years ago

It actually is. He talks about it in this video [1]

For some reason, I think this video will show up in my recommendations.

Not gonna click the link to see what happens. I'll come back here later to tell

exodust• 2 years ago

Nothing happens, it's a relative size demonstration. Earth is the grape, the sun an elephant etc. Black hole with 4m solar mass is just a large sphere. Good video, but there is no simulation.

atum472• 2 years ago

I'm just trying to see if there's any relation to what I browser vs what is recommended to me on YouTube.

I saw some video topics here that I haven't clicked that end up in my feed.

Going to leave this gem here:

Black holes are weird because they are essentially macroscopic particles with only one variable, mass (ignoring angular momentum, charge and other details for the moment). But they scale very strangely.

For instance, its interesting to see what a black hole is like that emits precisely 100W of radiation. Or that is as big as a apple, or weighs as much as a apple. Or one that lives exactly 100 years, or that is as dense as water (as black holes have the odd property of getting less 'dense' as their mass grows). Its very unintuitive, and just punching values into the calculator illustrates it perfectly.

I bring this up because the illustration (a town sized black hole sitting over New York) is a very specific configuration, and it doesn't really illustrate how oddly these objects scale.

What is a black hole's density?

hazbot2• 2 years ago

Mass divided by volume encased by the event horizon?

ithkuil2• 2 years ago

For me, the most counterintuitive thing is that the more energy you put in the colder the black hole becomes.

Is there any other object that behaves that way?

bonki• 2 years ago

Lots of human beings behave exactly like that...

nh23423fefe2• 2 years ago

temperature is analogous to surface gravity which gets weaker at the event horizon as the black hole grows.

temperature is not expectation of a kinetic energy distribution of micro constituents. you don't measure a black holes temperature with a thermometer because you can't get information out of a black hole

In Sweden, they actually have a permanent model of the solar system in the scale of 1 to 20 millions. The sun is the size of the Globen arena in Sweden capital Stockholm. Models of the outer planets are somewhere in the north of Sweden!

somewhere in the north of Sweden

This is an interesting perspective considering that this north of Sweden is not really very north and is much closer to Stockholm than say Malmö is to Stockholm.
